Radio Answers the Call of Total Defense Wi ith characteristic speed, radio today is responding to the call of national defense. Enrolled to serve the public interest and fortify the Nation's invisible life-lines of communication are: Research, Engineer- ing, Manufacturing, Broadcasting, Inter- national Circuits, Ship-and-Shore Stations. In 1919 the Radio Corporation of America was organized as an American-owned, American-controlled radio company. RCA has established a world-wide communica- tions system, independent of all foreign interests, and has pioneered in the creation and development of a new art and a new industry. Today, each of its services is equipped and ready for action in the first line of America's total defense on land, sea, and in the air. RCA CALLS THE ROLL OF ITS SERVICES TO THE NATION: WORLD-WIDE COMMUNICATIONS Vital to defense and commerce, RCA operates 24-hour direct communication service to 43 countries. This service avoids the censorship, errors, and delays which might occur at relay points. The Nation is protected against the loss of overseas communications through the cutting of submarine cables in war-time. Supplementing these globe- girdling channels, RCA operates a domestic radiotelegraph system that links 12 key cities in the United States. MARINE COMMUNICATIONS Life and property at sea are guarded by modern radio coastal stations and radio-equipped ships. Eighteen hun- dred American ships are equipped with RCA apparatus. The shore-lines of the United States are fringed with radio beacon transmitters to guide the fleet and shipping in American waters. American ships do not have to depend upon foreign-controlled means of communication to send messages home. RADIO RADIO TODAY BROADCASTING RCA pioneered in establishing the firsl coast- to -coasl network of broadcasting. The National Broadcasting Company, formed in L926, todaj serves an American radio audience through 50,000,000 receiving sets. NBC. provides these listeners with serious and popular music, in and information, drama and education, public loi is and religious services. Under the American sys- tem of broadcasting, t he finest and most extensive variety of programs to be had anywhere in the world is free to l he listening public. The richest man cannot buy what the poorest man gels free by radio. The broadcasting service of NBC is also maintained internationally, hv short wave, and helps to strengthen good-will and cultural and economic relations between the Americas, and with other parts of the world. An informed public opinion, promoted by a free press and a free svstem of broadcasting, is an important national assel in total deiense. MANUFACTURING The RCA Manufacturing Company operates five large plants, strategically located at Camden and Harrison, N. J., I ndianapolis and Bloomington, Ind., and Hollywood, Calif. \\ ithin the year the company has invested millions of dollars in expansion to facilitate production and rapid rilling of orders from the Army and Navy. Machinery is geared for national defense in addition to providing for normal requirements of the public. RESEARCH AND ENGINEERING Through science and research, the RCA Laboratories are enrolled in national defense. Research in electronics, wave propagation, television, facsimile, acoustics, optics, and in other fields has opened new services and extended the scope of existing services, both commercial and military. No longer must an aviator "just look to the ground" to find his way to a target or to his base. He may fly and land blind". by radio. The electron microscope, a product of RCA Laboratories, i^ a new means to help protect the national welfare as it opens new horizonsfoi bacteriologi I chemist, physicist and industrialist. In these and man) other ways, peace-time radio research has buill new bulwarks of defense for our Nation. INVENTIONS AND THEIR USE RCA licenses many manufacturers lo use its inventions and patents. By making them widely available, RCA has helped to create an industry as well as an art. Through this licensing policy the radio industry has access to results of the research of RCA Laboratories. In this way, competition has been stimulated, and numerous sources of supply opened to the publicand the Government. TRAINING More than 1,100 students are enrolled in the completely equipped schools of the RCA Institutes, Inc., in New York and Chicago. From this enrollment and from graduates of the Institutes, the United States can enlist the services of trained men in all branches of radio, from ship operators to service men. Scientists and engineers associated with RCA present and publish hundreds of scientific papers each year as aids to others interested in radio. For those who follow technical developments of the art, RCA Review, a quarterly journal, prints the latest scientific reports on progress in radio. EMPLOYEES Labor relations between RCA and its employees are excellent. Employment in the RCA organization in 1940 increased from 22,000 to 27,000 employees. Principal officers and many employees of RCA are members of the Army and Navy Reserves. For 21 years the pioneering efforts and services of RCA have safeguarded American preeminence in radio. RCA continues to serve the public interest and is fully prepared and ready to carry on in the first line of total defense!

For radio tubes and all their vacuum-tube cousins have become the new master-tools of science and of industry. Events all about us demonstrate that this is increasingly an age of Radio Magic — and that the world is entering upon a Radio Age. So far the coming of the Radio Age has been manifested chiefly in the world of thought — in science, in entertainment, and in communication. Now it is creating electronic devices which promise a similar revolution in the fields of industry. In other words, just as industry has moved from the Steam Age into the Electrical Age, it is now moving into the Radio Age. As we enter 1941 we are under tremendous pressure to increase our production in the national defense. Later, if, as, and when peace comes, we shall have the even more difficult problem of meeting world competition. In both cases, the answer must lie in the supremacy of America's mass production. Already we lead the world in that field. But radio can help us keep ahead. For there is no factor that can be more important in further speeding up mass pro- duction than the introduction of radio and electronic devices into the machinery of that production. We are probably doing as well now as any combination of human eyes and hands with electricity can do. By putting radio tubes and electrons to work, however, we can introduce a new factor of such precision, delicacy and speed, that we should be able to increase radically the output of our machinery.

JANUARY. 7947 Radio men can be counted upon to do their part in the big defense and armament program — directly, in arms production, and indirectly, in sustaining morale. Both are important. And manufacturers who temporarily turn their facilities in whole or part to war-goods production, are not under the necessity of sacrificing their regular distribution or markets. They should hold onto their regular outlets which will be again needed in the peace days that are also ahead. For eventually all radio men must take their places in a peace economy and help to build the bigger and better service of radio and television which the future promises. TODAY'S TRENDS Good Business Ahead for Radio Men Reports pouring in indicate that the Christmas season just closed rang up the greatest merchandising totals in U.S. history. Retail sales of all kinds ran ahead of previous years, and radio did its share of this record business. Meanwhile for the first quarter of 1941, radio men look for good busi- ness. Already the effects of the em- ployment and armament moves are being felt, but the full impact of the government's spending of billions will not reach the general public until the end of 1941 or the first half of 1942. Millions of people who have been off payrolls for years, at last are getting wage-envelopes regularly, and these folk have indicated that their first purchases are going to be radios, re- frigerators and other goods that stock radio dealers' stores. Prices May Go Up in 1941 Possible price increases are seen, as the rearmament program develops. Raw materials in certain lines are ex- pected to show shortages, with costs to radio manufacturers going up. Two alternatives face manufactur- ers in planning their future price schedules. One course will be to "up" the list prices, and raise the price J. M. Spangler of National Carbon Co., makers of batteries, has been boosted to vice-president as well as general sales manager. 1941 has already been called "radio's battery portable year." structure all along the line. The other course will be to trim present models of special luxury gadgets, and hold price brackets as before, but with slightly stripped models. The latter course will be especially difficult in radio, where essentials have to be whittled into, before any marked in- road of savings results. General feeling seems to be that great customer spending splurge is ahead, with millions having first easy money since 1928, and that radio as a "favored-item" purchase, can break upwards into new price levels in 1941. FCC-NTSC Television Conference Jan. 27 Early standardization of television will be considered at an FCC confer- ence in Washington, Jan. 27, with the National Television System Commit- tee. A status report and possible tenta- tive television standards will be sub- mitted by the NTSC. Agreements have been reached by some of the panels, or subcommittees, on television standards. Chairman W. R. G. Baker of the NTSC and all panel chairmen will participate in the January 27 confer- ence, called by the FCC on November 16, when the Commission also an- nounced licensing of ten additional television experimental stations, add- ing that the total budget of all experi- mental stations engaged in television research now amounted to $8,000,000. Members, of the FCC will visit the New York area Jan. 24 and personally inspect late television developments. Radio Gives 'Em Time to Pay Installment selling is more popular among radio dealers than among the retailers of any other trade except one, and that's auto dealers, according to the findings of Dun & Bradstreet in their 1940 Retail Survey. Retailers totalling 13,000, in 52 trades were surveyed as to their operations in 1939, and it was found that 81 percent of radio dealers extend installment credit. The figure for auto men is 86 percent, the top. It was found that the typical part of the total volume done on installment credit by these radio dealers was 47 percent. Other findings were that only 11 percent of radio dealers were doing a cash business, that is, 90 percent or more for cash. About 67 percent of the radio fellows extend open credit, and in these cases they do 22 percent of their volume via open credit. "This year, angels have us by the hand," was Sayre Ramsdell's enthusias- tic phrase as he predicted increased em- ployment and consumer spending, at Philco's distributor convention in Chi- cago. See page 46. Exchange of Ideas and Goods Of real import to the whole U.S. radio industry is an announcement made by William S. Paley, president of the Columbia Broadcasting System upon his return from a 7-week air tour of Latin America. Columbia will now extend its network to 18 of the 20 Latin American republics. Nego- tiations are under way to include the two remaining nations. NBC short- wave beam programs are already avail- able for rebroadcasting in South Americfi.

This "good neighbor" plan also includes the broadcasting hero of features originating in Latin America, Mr. Paley concludes that "the peoples of tin' two continents should know each other better ami whatever part radio can play in bringing this about should prove of immense value in relationships between the Amer- icas." Plans for Expanded FM Service Construction permit for the sev- enth FM station in New York City and the 26th in the country, has been granted to CBS, which will erect its 48.7 mc transmitter on the Salmon Tower, 42nd Street. Meanwhile the big- 40,000-watt Alpine station of Ma- jor Armstrong has gone to a program of transcriptions and records, but is understood to have applied for a com- mercial license. FM programs of WOR and WQXR continue in the metropolitan area. NBC has reconstructed its Empire State transmitter on 45.1 mc, and is now operating Saturdays and Sun- days, including the Metropolitan Opera and Toscanini programs, though off the air Mondays and Tues- days. New FM applications by Muzak, New York, and WIBG, Philadelphia, are also before the FCC, making a total of 58 FM applications now pend- ing at Washington. Broadcast Re-Allocation May Be Postponed The general re-allocation of broad- casting stations, which will affect most of the stations of the United States, may be postponed beyond the previous- ly announced date of March 29, 1941, because of international difficulties. This re-allocation, made under the Havana radio treaty, to improve broadcast reception in the Western Hemisphere, requires the approval of all nations concerned. Already Cana- da and Mexico have given their assent, but a snag has been struck with the Cubans. The IT. S. State Department will hold conferences late in January, in an effort to clear the remaining ob- stacle. But even if all nations are in accord by Feb. 1, there is still doubt that the re-allocation can be put through by the date announced, March 29. Radio Salesmen Work Hard for "Floor Time" At Max Barnett Furniture Co., New Orleans, La, radio salesmen sell one of the biggest volumes of business of the entire store — because radio department manager Mike Magoni believes in pro- viding an unusual incentive for his sales staff. Radio now has friends in the fancy poultry business — Wm. C. Grunow, left, and J. J. Davin, Sr., shown at Mr. Grunow's Val-Lo-Will chicken farms, Lake Geneva, Wis., where Mr. Davin is sales manager. It is his belief that more radios can be sold outside the store than it is generally felt possible — so many, in fact, that all the radio and appliance salesmen of the store spend the major- ity of their time on "outside calls." This outside selling program had one bad feature however, in that sales- men are likely to become discouraged with "cold canvassing." Accordingly, Mr. Magoni developed a selling plan which means that every man sells every week at least three radios, run- ning up to a minimum of $100 a week in "outside" business. "Floor time" in the first-floor radio department at the Barnett store, is naturally highly desirable to salesmen, inasmuch as there is a traffic of aro I 5,000 pei on dailj pa i the ection, \ n tl< tnai can swiftly close Bale i at this i I and u tia can earn the large tl pan of hi inc n the floor. Sewn ale men I pecialtj appli ances and radios) are concerned in 1 be plan. None can earn the right to spend a selling day on the radio partment floor until they have brought Mr. Magoni a fixed amount of out,.-."1 business which has been sold entirely independent of the store's help (no telephone inquiries, floor customers, etc.). When this quota is reached and checked at the end of the week by Mr. Magoni, the salesman receives one day on the radio floor; rotating days through the seven-man staff. So Long As They Shall Live There are a few married couples around the country who have a re- cording of those innocent and low- spoken words which marked the begin- ning of the joint life, be it bliss or battle. It happens that at their weddings, somebody hid in the shrubbery with a microphone and set a recorder to turn- ing, so that the fatal "I do," complete with music, was all registered on a permanent record. These discs become priceless as time goes on. They create a sensation when played at anniversaries, and the child- ren of the couple show a genuine, if perverse, interest in them. It's one of the most dramatic illustrations of the worth of home recordings. No doubt these wedding records are played sometimes when hubby gets tough, or the wife gets cross, in order to re-emphasize the "love, honor and obey" section. But the discs remain the most interesting document to be found in any of the bureau drawers. Bristling with "Blue Ribbons," GE execs are shown in Atlanta with new lines pre- view they gave in 9 key cities. Headquarters officials are A. A. Brandt, right, ladio sales manager, and Harry Deines, second from left, ad manager. See p. 47.

JANUARY, 1941 29 AUTO-RADIO OPPORTUNITY FOR PARTS DISTRIBUTORS Whenever a radio man can address the parts distributors of the country and say, "there exists today a very substantial and rapidly increasing market for service parts, which you are almost completely ignoring," then the trade will stop and listen. Such an undeveloped market for radio parts lies in the service depart- ments of new-car retail agencies, de- clares Ken C. Burcaw, sales manager for The Radiart Corp., Cleveland. "Now, most jobbers will say, 'My salesman contacts them — I am getting their parts business, but it is small.' WAKE UP, Mr. Jobber! You are only getting the crumbs from the table and perhaps not that. Go out yourself — call on these accounts and ask them how many aerials, vibrators, volume controls, condensers, resistors, control heads, etc., they are buying from their factories. Naturally, they are taught to buy these, sometimes even kidded into believing they have to. This in itself should constitute a challenge to every jobber to get this business. ONE JOBBER'S STORY In making similar statements at jobber sales meetings, I have been in- vited to prove my point, and naturally that constituted a challenge to me. It is always a pleasure to accept such a challenge, for, if advantage is taken of the relative positions, the situation certainly is in the jobber's favor. "Here is an actual experience to- gether with a few added points which were not needed to sell one "X" car dealer. "John Doe, a very good parts sales- man for a large mid-western parts job- ber, dared me at a sales meeting to spend a day with him. The following day I made four calls with him, selling all four accounts aerials for a total of 78 units. He then took me to "X" car dealer hn whom he admitted he never called. Naturally, it is doubly hard if the dealer does not know the salesman or the company he repre- sents. PROFITS FOR ALL "Bill Jones, the sales manager (it is advisable to talk to the sales man- ager), assured us that the parts man- ager handled all such matters and that all accessories were "X" car acces- sories. I took time to talk to some of Bill's salesmen on the floor, and found out that they had actually lost sales on radios because the only aerials they had required drilling the body of the car. Some customers just won't stand for drilling their new cars, and there- fore all this business was being lost. We sold Bill Jones on underhood bracket aerials right then and there — and with that, he took us to the gen- eral manager and sold the idea of underhood aerials for us. They called the parts man up and told him to give us an order for twelve aerials. "Having established ourselves, we felt it was time to do the dealer a REAL favor. Bill's floor salesman had also revealed to us that he, and the other boys, had been telling customers that only "X" car radios and "X" car antennas would work on "X" cars. He also stated that they have had people walk out because they could 'Every Second Cor You See" Is Prospect for Auto-Radio Radio servicemen and dealers have a great unsaturated market in auto-radio. Look at the cars parked or passing, and realize that at least "every second car" is an immediate opportunity for sale of an auto-radio receiver! not use their old radio (which was satisfactory in every respect) in their new cars. Many car salesmen are do- ing this same thing! Yes, you're right — we sold him control heads. He then spoke to his salesmen for he did not want people's confidence destroyed in his organization by such a policy. MAKE FRIENDS "People eventually do find out they can use their old set in a new car. When this happens, the result is that they will never go back to that dealer again. Suggest to the dealer also that a good radio service department is just as important as a good motor ser- vice department. "Show him that you have parts for all the old sets he gets in in trade so that he can put these in perfect order. You are a local business man and many of your employees are his poten- tial customers. No one need ever be ashamed of the old reciprocity argu- ment. His car salesmen use it every day. "Incidentally, the jobber recently wrote me stating that Bill Jones now averages $350.00 per month. "Don't forget he often gets 25 per cent or 30 per cent from his suppliers, where you give him 40 per cent, and he frequently pays transportation from the distributor or factory. Frequently he is required to buy large standard packages. You are close by and can give him service thereby reducing his inventory. " Most of all, go out and try this yourself. See it work, and then see that your salesmen use it!" Jobber Accents Credit Standing A novel postcard, which calls atten- tion to "our reputation for meeting our obligations" is used by the parts jobbers, Dymac Radio, Buffalo, N. Y., as a regular reminder to credit man- agers that "in every case we've kept our word." When the firm pays a bill, the payment is followed some weeks later by the card, on which is also noted the date of the bill and the date of payment. The card says, too, that "at times during the past 18 months of expansion we've felt somewhat pinched," but adds that "Dymac re- members!" Dymac presents itself to the trade as "the fastest growing radio, photo and model distributor in western New York" and uses the slogan, "Service — Our Key Word." Distributor Enlarges Branch House From Radio Service Laboratory, 1191 Elm St., Manchester, N. Y., comes the news that the company has moved its branch at Bangor, Me., to new and im- proved quarters at 45 Haymarket Square, that city. This prominent job- ber also has branches at 34 Free St., Portland, Me., and at 188 S. Main St., Barre, Vt. Radio Service Labs has just issued a new 200-page catalog, with an at- tractive fund of up-to-the-minute in- formation on radio parts and sound equipment. It is available from Man- chester. 30 RADIO TODAY Two More Execs in Sonora Expansion Ed Harris of Sonora Further news of the sales expansion of the Sonora Radio & Television Corp., Chicago, is an announcement by president.

Speaker compensating resistors. Winter sound jobs are found in school, church, and civic auditoriums. Here, the plays, graduation exercises, musical programs, and town meetings will be given, and here are the sound installations to concentrate on. Many of your previous installations will need new equipment for either replacement or modernization. New school systems are using two-way communication in addition to the usual sound distribution network. Bi- aural systems are receiving more con- sideration and many present installa- tions can be converted by adding an- other amplifier and locating additional speakers. Sound jobs, such as these audito- rium installations are bringing profits to PA specialists. One of the many ex- amples is the school sound business garnered by Hunter Radio Shop, Enid, Oklahoma under the direction of Walter C. Hunter. The recent completion of the Enid, Oklahoma high-school sound job by Hunter wound-up the program of pub- lic address installations for the three secondary schools of that city. USING MULTIPLE SPEAKERS The first school equipped, Longfel- low Junior High School, utilizes 22 five-inch P.M. dynamic speakers baffled in wall-type cabinets. Each speaker is equipped with a matching transformer reflecting 2,000 ohms impedance into the line. Single- pole, double throw switches and 2,000 ohm one-watt resistors are used at each speaker to compensate for the load when speakers are turned off. Parallel lines feeding out from the of- fice accommodate the various branches of the building. The loads reflected by each of these branches (2,000 ohms divided by the number of speakers on a branch) were added by series con- necting the various branches. By this method it is quite convenient to build up a reflected impedance close enough to one of the several available output taps (2, 4, 8, 16, 166, 250 and 500) and form quite an acceptable "match." INFINITE BAFFLE The amplifier uses push-pull parallel 45's, a 56 and a 57. An American double button carbon microphone, de- riving button current from a well by- passed tap on the 57 bias resistor, is used. A small AC-DC radio, with a power line isolation transformer, a phono-motor and pick-up complete the installation. Emerson Junior High School uses 42 eight-inch P.M. dynamic speakers equipped with 2,000-ohm matching transformers, 2,000-ohm one-watt re- sistors with S.P.D.T. switches. Emerson is designed with air shafts from the attic to each room. The building has three principal floors so one shaft in each tier reaches from the attic to the basement. By mounting the speakers on 12 x 12 x % in. flat baffles and cutting a 10-inch round hole through the "Masonite" bulletin borders over the black boards and through the chalk tile of which the air shafts are constructed, it was pos- sible to mount the speakers in true infinite baffle manner. Each tier of speakers is fed by a line dropped from the attic. The amplifier is a Vocograph 30-watt unit. The speaker lines are matched in the same manner as in the Long- fellow H.S. installation. A Shure crystal microphone, a phono-motor and pick up, and a large console radio complete the central system. TWO WAY SYSTEM In the auditorium, two 12-inch P.M. dynamic speakers are mounted on flat baffles — cut back into the proscenium fan rooms to provide infinite baffling. They are fed by push-pull parallel 45's. The voltage amplifiers are one 57 pen- tode into one 57 triode into cascade 56's. A third 56 fed from the first 56 is used as a cathode follower to feed the central amplifier in the office. Thus the entire school may listen to any- thing originating in the auditorium, the vocal or instrumental music rooms. The stage amplifier may also be fed from the central amplifier speaker lines. This makes possible amazing two-way conversations and programs from the office and stage without switching or volume adjustments. ELIMINATING HUM The Enid High School system, re- cently completed, uses 70 four-inch P.M. dynamic speakers housed in bass reflex baffles. Matching transformers reflecting 7,000 ohms are used at each speaker. S.P.S.T. switches in the voice coil leads are found quite satis- 32 RADIO TODAY factory. While opening the voice ooi] circuit causes a rise in reflected lm- pedauce in the primary of the match- ing transformers, no ill effects are noted even when many of the speakers are "off." Speaker line branches are connected in series to approach a '•match" at the Audiovox 30-watt am- plifier. Operadio record playing equip- ment and a Howard 435 communication receiver provide phono and radio fa- cilities. The microphone is an "As- tatic" crystal unit. Parallel cotton covered number 18 wire is used for speaker lines. It Is tacked to the plas- tering along the halls and drops are' fed into each room through a small hole in the non-opening transoms. By working these drops around the mould- ing to the bottom of the transom the hole is easily concealed. The wire is tacked along a color break of a so- called dropped ceiling and is not no- ticeable. It is well to mention that almost all hum, distortion or transient "bugs" Emerson's principal, i>. Roj Daniel, Longfellow's Leon R, Vance and the High School's D. Bruce Selby, assisted in the installation. It Is of mutual ad- vantage for the principal to assist in the installation since he knows the building so well. Such teamwork gives a greater knowledge of the system to the principal and leads to better use of the facilities. Frequently a principal can be shown the advantage of an inexpensive sound installation much more easily than an entire board. Emerson's system was financed by two plays; the High School's out of the athletic fund.

The footlight microphones normally operate at maximum sensitivity; the stand microphones, of course, are op- erated at various levels depending on their particular use. The central control unit incorporates a voltage amplifier with individual in- puts for the microphones, a 50-watt power amplifier and a monitor ampli- fier which in addition to actuating the monitor speaker feeds a line to ten hard-of-hearing aids located in the up- per tier of seats of the auditorium, a feature which adds greatly to the utility of such an installation.

The added sensitivity and selectivity of an RF stage is possible with a two-gang condenser and the type of inter-stage coupling used. Several parts of the circuit are dif- ferent from the usual practice. The B-|- supply is filtered by choke action through a part of the output trans- former primary. By supplying the plate current of the output tube through one section of the winding and the other tubes through the lower portion of the winding, core magneti- zation due to the DC is reduced, thus permitting better audio quality. A ten-meg resistor between the oscillator grid and the AVC bus pro- vides a small negative bias voltage to control the tubes at zero signal. IF ALIGNMENT Feed a 455 kc. test signal through 0.1 mfd. capacitor to grid of 12SK7 IF tube and tune dial to quiet point around 1600 kc. Adjust secondary and primary of second IF transformer. Reconnect signal to 12SA7 detector grid and adjust secondary and primary trimmers of first IF transformer for peak response. The short-wave band is aligned with a 19 mc. test signal fed to the an- tenna post through a 47 mmfd. ca- pacitor. The tuning dial is set at 19 mc. and the oscillator trimmer on the tuning section is adjusted for maxi- mum response. The short-wave an- tenna trimmer (C31) is peaked while the signal generator is radiating a 18 mc. signal through a short piece of wire. The dial is tuned to resonance with the signal. A radiated signal of 6.1 mc. is tuned-in and the inductance of the short-wave antenna secondary is varied for maximum output by dressing the AVC lead near the coil. Connect a 1720 kc. signal to the an- tenna post through 200 mmfd. capac- itor and adjust the oscillator trimmer for maximum. This trimmer is across the oscillator coil. The dial is set at 1720 kc. for this adjustment. A ra- diated signal of 1400 kc. is tuned in on the set and the antenna trimmer (C33) is peaked. Connect the signal generator through the 200 mmfd. ca- pacitor to the antenna post and adjust the oscillator tracking padder for max- imum indication at 590 kc. The broadcast band alignment should be repeated for accurate re- sults. Stage gain figures shown at the top of the diagram serve to check the sets which do seem to be quite up to par. The 5X figure for the 12SK7 RF tube means that a signal voltage of some value on the grid of the tube will be five times as great when measured at the plate of that tube. These figures are approximate and were measured with a RCA Rider Chanalyst. The values for the DC oscillator grid volt- ages at different frequencies are also shown. These may be measured with a VTVM. Note that when making gain measurements of tubes, a fixed AVC voltage of 3 volts is used. Stewart-Warner Models 7 7-704 and 11-10AZ Audio howls in these sets may be corrected by one or more of the fol- lowing means. The chassis must be allowed to float on the rubber mount- ing cushions. Loosen the four mount- ing bolts which hold the chassis and also remove the wooden strips which may have been used for shipping. See that the knobs, shafts, and dial me- chanism does not touch the cabinet. On chassis not stamped with letter S, a tendency to howl or rumble may be stopped by changing the .01 mfd. audio coupling condenser from the diode load resistors to the radio-phono push-button key to 0.002 mfd. Re- placing the rear rubber grommet on the gang tuning condenser with a soft gum rubber type will clear up the last bit of trouble. The washers and mounting bolt are not replaced if this is done.

I (ll)C \ Magnified orbss^sec- Hon of finished resistor to ehow exclusive in- ner construction. Flattering and widespread imitation following IRC's development of the Insulated Resistor with its obvious advantages as compared with old-style, non-insulated units has resulted in such uniformity of appearance that it is difficult to distinguish one make from another. This similarity, however, is only skin deep— only as deep as the insulation. What lies beneath is of the utmost importance from the standpoint of performance. The outside insulation is important only because it protects the inside resistance element, prevents shorting and facili- tates rapid and economical assembly. Not this protection but what it protects is the final determining factor of quality — and it is under- neath this insulation that insulated resistor similarity ends. As an outstanding example, the IRC type BT insulated resistors, comprising the unique "Metallized" filament element and specially developed insulating phenolic covering, have humidity characteristics hitherto un obtained. More than 10 cycles of alternate two hour im- mersions in 100°C and 0°C. salt solution followed by two hour loadings at normal rating result in an average change in resistance value of less than 10%. In connection with the present defense program such performance is essential for dependable communication equipment but it is also obviously very important for all commercial applications.

JANUARY, 1941 39 SOUND IN AUDITORIUMS (Continued -from page 33) specifying acoustic plaster for the en- tire ceiling and upper portions of the interior walls. This, of course, is a contributing factor in the excellent sound coverage obtained. The acous- tic plaster to a great degree compen- sates for the absence of any other sound absorbing material. The sound installation was made by the RCA- Victor distributor at Kansas City, Mis- souri. Even with overflow crowds, which have exceeded six thousand persons, perfect sound coverage is obtained with the amplifier operating at only a small portion of its total rated output. Now is the time to analyze the auditorium in your vicinity and then design a complete sound system to do the job. Recorder and Phono Servicing Notes "Wow" or the wavering of pitch during the playing of records or home recordings is a particularly annoying trouble with turntable mechanisms. The type of "wow" falls under one of two classifications; intermittent varia- tion, or variation synchronized with turntable rotation. These notes are from the Wilcox- Gay Corp., Charlotte, Mich, and while they apply in particular to models A93 and A94, much of the data is appli- cable to all types of recorders and record players. For the intermittent varying va- riety, the following suggestions will usually clear up the trouble. First, the old stand-by, be sure the rubber tired drive wheels are clean and free from oil, or grease. The wheels should run freely in their own bearings though, and a drop of oil is occasion- ally needed. The bearings should be free from any side-play, that is, the bearings should be tight. The inside rim of the turntable should also be free from oil and dirt. If speed variation still exists, the tension on the rubber rimmed drive wheels against the turntable rim should be increased. If the drive wheel or wheels are allowed to ride up on the turntable rim, it is possible that they will rub Position of lubrication points for auto- matic record changers. on the under side of the turntable and slow it down. Intermittent variation of the turn- table speed on record may also be due to binding of the lateral feed screw bearing. An adjustment is provided on the gear housing to take up end- play, and the correct adjustment is one which gives only a slight amount at any point in a complete rotation of the feed screw. SYNCHRONIZED VIBRATION If the "wow" occurs each time the turntable makes a certain part of a revolution, the trouble is usually due to a flat spot on the rubber rimmed drive wheel, or an out-of-round turn- table. The inside rim of the turntable should be perfectly round and mod- erately smooth. The table should be replaced if it is damaged. Warped records, or records with oversized center holes are also causes of "wow." If the "wow" is being cut into home recordings, the cutter head damper may need adjusting. 1. The adjusting screw should be turned to the right so that no pressure is exerted on the cutting head by the felt damper. 2. Raise the recording arm to a vertical position so that the stylus screw is midway in the slot in the front end of the arm. The cutter head should oscillate back and forth when moved. 3. Turn the damper screw to the left until the stylus screw returns to the center of slot without oscillating when it is moved to one end and released. Frequent oiling of recorders and record players is not required. A small amount of oil should be used about once each year for best results. The diagrams show the points where lubri- cation should be applied. The turn- table is removed by applying upward pressure around the rim and gently tapping the top of the spindle. Two or three drops of electric mo- tor oil is applied at A, turntable shaft bearing; B, upper motor bearing; C, between drive wheel mounting disc and bed plate. At D, place a coating of petroleum jelly on the lip of the master cam. Two or three drops of oil can be placed on the recording arm pivot post E, and the straddle plate slot, F. FM, Tele Simultaneously On Same Antenna FM sound and television video sig- nals are being radiated simultaneously from the big video antenna on top of the Empire State Building, New York. This antenna was designed to cover the broad band from 30 to 60 mega- cycles and therefore can be used to transmit the FM sound signal at 45.1 mc. and the video television signal at 51.25 mc. if suitable means are used to prevent each signal from feeding back into the other transmitter. A unique system of cut-off filters eliminates in- terference between the two signals at each transmitter. A recent test demonstrated that no interference resulted at the receiving end when both FM and television transmitters were operating together. The FM station is operating five days a week and the television station operates for approximately four-hour periods three days a week. The Counter Display That Says — Buy HOWARD D/scs NOW!

Connor spoke recently before Hempstead, N. Y. RSA Chapter, Jean Lapler chairman. New circuit changes and FM were dis- cussed. RCA Models VHR-207-407 These home recording phono-radios use DC on the filament of the 12SK7 mike pre-amplifier tube to reduce hum. This DC voltage is obtained across one section of the bleeder network. Be- cause the filament is "below ground" and across the grid bias section of the bleeder, it will be burned out if the B+ is shorted to ground. The extra flow of current through the 2000 ohm section from the transformer center tap to the rectifier filament through the short will increase the voltage drop enough to burn out the filament. Use a voltmeter, not a screwdriver to check plate voltage. Stromberg-Carlson Models 505 and 575 A reduction in sensitivity or com- plete loss of signal on the FM band In either of these models may be caused by the 22M resistor connected between ground and grid end of the second IF transformer heating and changing value. Most cases of this trouble can be corrected by removing the resistor from the circuit. If oscil- lation should result after the resistor is removed, replace with new 22M unit.

Price, $1.25 An understanding of the basic tool of the serviceman, the electric indicat- ing meter, is the result of reading this new text. Its ten chapters cover the various types of instruments, their uses, and their limitations. A few of the chapter titles are, Mov- ing-iron meters, which are commonly used for AC instruments; Moving-coil meters, the most common of all DC indicating meters; Electrodynamome- ter meters, the combination current and voltage measuring instrument used to indicate electrical power. Other chapters deal with thermal and electrostatic meters, mechanical features of design such as damping, bearings, magnets, scales, etc. Elec- trical characteristics of various meters and their effects upon circuits under test show the proper methods of ap- plication. The physical make-up of "The Me- ter at Work" is entirely different from other texts in that each page is divid- ed so that a diagram, picture, or form- ula occupies the upper third and the text material the lower two-thirds. This permits the reader to have before him at all times the particular dia- grams referred to in the text. This text has much information that will help the serviceman to further understand the instruments which give the clues to set troubles. A KEN-RAD DEPENDABLE^ RADIO TUBES! Make 1941 a Ken-Rad year.

One of the major obstacles confront- ing Edison in developing the phono- graph some 50 years ago was the design of a stylus, or needle, capable of reproducing the recorded sound clearly, without destroying the record. In Edison's characteristically thor- ough style, every known substance was used — and discarded, until a permanently installed sapphire needle was tried. At last he had found the ideal ! While the records we enjoy today are sturdy beyond comparison with the frail wax records of the I890's, the requirements of high-quality repro- duction — without record wear — still must be met. Today, as then, the permanently installed sapphire needle ideally meets every require- ment.

"Profitizer" to Compute Expense and Profit In the conduct of any retail business the relationship between expense and gross profit is one vital factor the mer- chant must have at his fingertips. For easy reference, these two figures are always expressed in percentage of selling price. Percentages of course, are simple to work with, easy to compare. But complications soon present themselves to many dealers, when the practical applications to their daily business make it necessary to figure percentages quickly and accurately. Some use the "rule of thumb," some guess, and some just don't bother. There is a little slide rule called the "Profitizer" made by Smith Lee in Los Angeles, Calif., small enough to tuck in a vest pocket, simple enough for a child to use, inexpensive enough for anyone to own, that solves all of these retailers' percentages in no time at all. EASY COMPUTATIONS Knowing your cost and selling price it will quickly tell you gross profit in per cent of selling price or markup in per cent of cost. Knowing your cost and desired gross profit, it will quickly tell you necessary selling price to maintain the desired gross profit. Knowing selling price, and per cent of discount, it will accurately tell you the cost. Knowing desired "gross profit" ex- pressed in per cent of sales, it will tell you "markup" in per cent of cost necessary to attain the desired gross. Knowing your cost and per cent markup, it will tell you selling price in dollars, to give you desired gross profit. This little "Profitizer" will throw the "rule of thumb" out the window and take all the irk out of the work of figuring percentages. It's a great little aid to any merchandiser.

Lo- cated here in the Empire State we use only local calls such as WTRY, WGY, WOKO, WABY, WABC, WEAF, WJZ, WOR & WTIC. These are either Capital District or Metropolitan Dist- rict calls. Our shelves contain a hundred pack- ages of call letters which are useless to us because the stations we use are not to be found there. However, they are full of value to fellow dealers and servicemen who are located in a differ- ent part of this great country of ours. I would like to exchange call letter packages with some other dealers and servicemen, who do not use the same calls as I use. These are for Philco sets only. If the dealers would advise what they have, I am sure we could both profit by the exchange. Very truly yours, Edward Scribner Schoharie, N. Y. Rainbault Named Manager of GE Air Conditioning John P.

It is significant that the U. S. Forestry Service is a steady user of RAYTHEON Tubes. Their engineers have found that RAY- THEONS can be depended upon even for use in portable two- way equipment carried in packs over rough mountain trails for use in EMERGENCIES! Replacing tubes in home receivers, auto sets and amplifiers may present easier problems, but the same dependable RAY- THEONS are available and cost not one penny more than ordinary tubes. No wonder the ENGINEERS among Servicemen use them exclusively. Over 9,000,000 push button radios must he reset for the new frequencies. This is a good time to replace weakened tubes with RAYTHEON and increase your service business in general.

Radio men report that this advance wave of Defense pros- perity is now beginning to reach radio channels — in full force! Already it is reflected in new purchases of radios, phonograph units, records, portables, service jobs, and electrical appliances. Meanwhile the more aggressive radiomen are going out after particular people who have new jobs or new payroll increases. They are selling where there's new-found "cash-in-pocket." How this Defense upsurge has worked out in one typical American community and its effect on local radio outlets, is described in detail in following pages. Here is a lesson for every community and for radio men everywhere. Radio prosperity, like all prosperity, goes to the man who goes after it! EDITOR, Orestes H. Caldwell; PUBLISHER, M.

MARCH 29TH Another great impulse to radio and service sales is handed to radio men in the FCC's order changing the channels of 795 of the country's broadcast stations on March 29. This means that 11 million push-button sets will need resetting after March 29. So the door will be opened to homes everywhere for receiver inspection and overhauling, and for tube and parts replacements and even receiver sales. What to tell the customer, how to reset different circuits, and how to cash-in on the results of this great March 29 "Mov- ing Day", are all outlined in this issue — with more details to come next month. In this great open-season for servicemen, caution must be observed that button resetting and overhauling be done care- fully and conscientiously. Radio will be given a black eye locally if this opportunity is seized by a few to go "off-side" in straight-arm selling or bad servicing. Every qualified serviceman will use it as a great oppor- tunity for real service to the public, in restoring good reception after the stations shift March 29. FEBRUARY, 7947 7 7 TODAY'S TRENDS Retail Sales Speed Up General retail sales in all parts of the country are reported as 5 to 7 per cent ahead of corresponding sales for a year ago, with the national average running somewhere about 6 per cent increase. Defense speed-up has built up em- ployment rolls and pay-roll increases, and these improved conditions are be- ginning to be shown in sales of ra- dios and electrical appliances, one of the first directions in which new pur- chase money goes. To Explain Re-Allocation Benefits To explain to the radio audience why the coming March 29 Broadcast Re-allocation was necessary, and why it will improve reception for both rural and city listeners, Editor O. H. Caldwell of Radio Today will tell listeners about the great shift of 795 radio stations, during his regular "Radio Magic" program, Friday, Feb- ruary 21 at 7:15 p.m. EST (6:15 CST) on WJZ and NBC's Blue Net- work. "Radio Magic" programs at the same time on following Friday eve- nings, will give further timely hints to radio listeners in connection with the re-allocation shift, advising how to utilize the services of radio men to reset push buttons, check tubes, parts and antennas, and eliminate electrical interference. RMA Making Defense Survey Under the direction of Bond Geddes, executive vice-president, the Radio Manufacturers Association is surveying by questionnaire the plants of radio manufacturers. While the questionnaire is brief, it is carefully drafted to bring out all of the essential facts and will give a complete picture to the national defense organization and government officials, as well as the industry, re- garding productive capacity for the national defense program. The sur- vey is designed also to assist in the sub-contracting program now being- urged by the government. Twelve Million Radios in 1940? Previous estimates regarding the number of radio sets made and sold by American manufacturers during 1940, appear to have been on the side of conservatism. Now that more com- plete figures for the year are avail- able, revised estimates indicate that approximately 12,000,000 sets were sold, including exports, automobile radios, and all types of sets. By months, (with December esti- While Philco continues radio promotions on "music on a beam of light", the firm also starts the refrigerator season with '41 convention orders double last year.

Tube Prices Go Up Early this month, the advancing prices of radio's raw materials be- came a very tangible factor in the boost of list prices. Throughout the tube manufacturing industry a 5 cent average increase in tube lists became effective, with an appropriate lift in wholesale prices. It was pointed out that since tube prices had already been pared and re- pared until the profit margins were smaller and smaller, that any rise in the cost of making them would be sensitively reflected in list prices. Court Upholds Stamp Ban The 1939 "Wisconsin trading stamp law, which prohibits the issuing and redeeming of trading stamps with the sale of fair trade merchandise when redemption of the stamps would bring the net price below the producers' es- 72 RADIO TODAY tablished minimum price, was held constitutional last month by the state supreme court. The plaintiff stores were sustained in their contention before the lower court that the law was "unconstitu- tional class legislation" by Circuit Judge Qustav (J. Gehrz. 11 is opinion is now overruled by the high court. The supreme court pointed out that it had previously upheld the state fair trade act and that the trading- stamp law related directly to that aet and consequently the stamp measure was not "indefinite and uncertain," as the plaintiff stores had claimed. The decision stated that "this chap- ter (trading: stamp law) was designed to fortify the earlier act and to pre- vent what the legislature considered to be a form of price cutting. J. H. Rasmussen is the new manager of Crosley Corp.'s radio division. He'd previously held key sales posts with Zenith, Grunow, and others. FM Plans Go Ahead More than 30 construction permits are now approved by FCC for new fre- quency-modulation transmitters, while some -56 FM applications still await the attention of the Commission. Zenith Radio Corporation, recipi- ent of a construction permit for an FM station in Chicago, has signed a nine-year lease with Chicago's 600- foot Field Building. The agreement becomes effective May 1 when Zenith's 50,000-watt FM transmitter starts oper- ation on a commercial basis as W51C. Meanwhile, WGN is reported rushing completion of its FM installation on the 25th floor of the Tribune Tower. Both stations will cover a wide area of 10,800 square miles in which some 4,500,000 persons reside. First capsule for space at the Radio Parts National Trade Show, June 10-13, is drawn by Helen Staniland, Quam-Nichols vice-president, who hands it to Show committeeman E. S. Riedel of Raytheon. Irving Kahan, left, of Sprague Products, finds the number to be that of John Rider, radio publisher. The Stars of f he Radio Business The comparative popularity of the various programs on the air is of everlasting importance to the men who are selling sets. If a retailer does not know which are the favorite programs, he is apt to leave a ranking comedian or a great singer out of his sales talks. Each year, the New York World- Telegram polls the radio editors of the nation for their program prefer- ences. The paper has released the results of its tenth such poll, and the vote shows that the top show is still Jack Benny, with Fred Allen second, Information Flease third, Bob Hope fourth, and Fibber McGee & Molly fifth. The much-dialed Mr. Benny wa9 also named the leading comedian. Other broadcasts picked in the poll included Information Please as the best quiz show, Guy Lombardo as the No. 1 orchestra, Bing Crosby as the male singer, Kate Smith as the girl singer, Bill Stern as the top sport announcer, Raymond Gram Swing as the favorite commentator, Lux Radio Theater as the best dramatic program, Irene Wicker as the leading enter- tainer for youngsters, Lily Pons as the top classical singer, Toscanini as the symphonic conductor, and Dinah Shore as the "new star." Stromberg-Carlson's merchandising plans, in which FM plays big part, get the once-over by general sales manager Lloyd Spencer, with book, and Jenkins Music execs.

For this report, the magazine's re- porter took the trouble to interview, in Lancaster, seven radio dealers, two radio jobbers, the local Manufac- turers' Association, the Chamber of Commerce, three of the leading man- ufacturers, the local Unemployment Agency, two bankers, the local De- fense committeeman, the town news- paper, and a string of citizens.

The full effect of re-employment and payroll in- creases are si ill to he felt. But radio men agree that a general tone of im- proved business is already there, and thai it's time to think of the methods for handling it. Lancaster, like many other Amer- ican cities whose industries are pre- dominantly average-sized and well di- versified, will never let itself in for a terrific "boom" as Government orders rush in. The town is located in one of the richest agricultural counties in the U. S. and the local in- come is neatly balanced between farm products and industrial wages. Yet this type of city is in position to make more than a dozen different products for Uncle Sam. Current orders are for parachute silk, aircraft watches, army socks, bearings, forges, coat hooks, life preservers, army cots, shells, mosquito netting, anchors, wood-working machines, buoys, as- bestos cloth, padlocks, etc. And the plants are humming, whether it's due to generally im- proved business or defense orders.

At the Animal Trap Co. of America, near Lancaster, where Defense committeeman Wool- worth is president, defense orders so far amount to $328,000 and the firm has bid on $935,000 worth. For pro- duction peaks, this company hires an extra 100 or so workers. WORKERS CAN BUY All this is expected to boost the $50,000,000 annual retail business reg- ularly done by Lancaster business men, to a new figure for 1941. And as the city's normal number of em- ployes grows from 27,000 to a fresh total, the other economic element in the area, the farmers, will be bene- fited. The local farmers now make a practice of bringing their products to Lancaster's five markets, where they sell direct to townpeople. As the city folks' incomes increase, these markets improve, and farmers are in better position to buy more radio products. Now, what are radio men doing about the pickup in business? Radio man Arthur C. Brown at Kirk Johnson's, who is working now against a background of "a very nice radio business," is planning some new promotions of a general nature, par- ticularly on higher priced sets. More salesmen will be added.

At the Armstrong Cork Co., whore 3 in. anti-aircraft, and 75 mm. ex- plosive shells are ordered, the firm takes on 100 additional workers at a clip. Armstrong regularly hires nearly 5,000 workers. De Walt Prod- ucts Co., which deals in wood ma- chines, is planning to doube its num- ber of employes. At the Animal Trap Co. of America, near Lancaster, where Defense committeeman Wool- worth is president, defense orders so far amount to $328,000 and the firm has bid on $935,000 worth. For pro- duction peaks, this company hires an extra 100 or so workers. WORKERS CAN BUY All this is expected to boost the $50,000,000 annual retail business reg- ularly done by Lancaster business men, to a new figure for 1941. And as the city's normal number of em- ployes grows from 27,000 to a fresh total, the other economic element in the area, the farmers, will be bene- fited. _ The local farmers now make a practice of bringing their products to Lancaster's five markets, where they sell direct to townpeople. As the city folks' incomes increase, these markets improve, and farmers are in better position to buy more radio products. Now, what are radio men doing about the pickup in business? Radio man Arthur C. Brown at Kirk Johnson's, who is working now against a background of "a very nice radio business," is planning some new promotions of a general nature, par- ticularly on higher priced sets. More salesmen will be added. He believes that radio volume in 1941 will be (Continued on page 24) 75 What to Tell Your Customers, Why the Re-Allocation Was Necessary. More Dollars from Resetting Push-Buttons and Overhauling Sets. Next month most of the broadcast- ing stations of the United States will move to new wavelengths. This means that after March 29, most stations will be found at new positions on all radio dials. For some stations the shifts will be slight. For a very few stations there will be no change of position at all. But certain stations will have to make wide jumps, half way across the dial (see accompanying table). On dial-type radios, after the March 29 "Moving Day," most sta- tions regularly heard in your town will be found somewhere near where they were before — usually higher. MAKE CLEAR TO THE PUBLIC THAT— On push-button radios, however, the buttons will have to be reset for all stations that are moved at all. This will mean calling in a competent radio man — to reset the push-buttons and to re-tune them squarely on the new station positions — so that the listener may once again get clear undistorted reception. This March 29 change in station positions will bring improved recep tion, especially to those who live in rural districts. City reception is also expected to be improved. And sub- ruban reception will undoubtedly be as good as before. Besides improved reception, the radio-set owner can also take satis- faction in having a part in a "good neighbor" gesture to our fellow Amer- icans to the South, as Uncle Sam "moves over," slightly, to make room in the ether for Mexico and Cuba ! For the principal result accom- plished by the coming reallocation will be to provide special channels for the big Mexican and Cuban stations which have developed during the years since the last broadcast alloca- tion was made in 1928 by the original Federal Radio Commission. You see, there were no Mexican or Cuban stations of any power when the existing set-up was originally made 12 years ago. At that time the small stations then operating "south of the border" could be easily accom- modated in the same channels as U. S. and Canadian stations because of the blanketing effects of tropical static. In the last few years, however, Mex- ico and Cuba began to acquire more and more — and larger and larger — broadcasting stations. MAR. Mexico, for example, today has the most powerful transmitter in opera- tion in the Western Hemisphere — a station of 350 kilowatts power — seven times as powerful as the largest transmitter now authorized to op- erate in the U. S. As these big stations South of the border came on the air, their opera- tors, finding no assigned space for them in the radio spectrum, sand- wiched them in between U. S. "clear- channel" stations which, like all U. S. stations, are on even-10-kilocycle as- signments. Some of the foreign high- power stations thus took channels with 5-kilocycle designations, half way between. Each such interloper thus spoiled reception of two im- portant U. S. broadcast stations, over wide areas. In other cases, the in- truding stations came squarely on U. S. channels, producing bad hetero- dyne interference all over the United States, in regions 50 miles or more from the transmitter. So bad had this interference from across the bor- der become, in the radio sets of rural and small-town dwellers all over the United States, that "something had to be done." INTERNATIONAL CONFERENCE So a conference of the principal North American nations was called at Havana a couple of years ago, and ef- forts were made to provide a sound engineering allocation of the 1300 broadcast stations on the North American quadrant, just as if all Use the Pushbutton Change, March 29th, To Sell- Tubes, Parts Antennas Noise-elimination filters Overhaul jobs Vibrators Extra radios Portable radios Full-BC-band radios (550- 1600 KC) Record-players and records Electrical appliances 76 RADIO TODAY BIG BROADCAST SHIFT 1300 stations were under one single authority, instead of being operated five nations, each with sovereign rights to all the wavelengths. Che Canadian, Mexican and Cuban stations, of course, have only the same ether to work in as our U. S. stations. And being sovereign nations, Canada, Mexico, Cuba and the rest feel that they have just as much right to use the whole broadcast band of 105 chan- nels as we have. Of course, if each nation insisted on its sovereign right to use all 105 channels of the broadcast band for its own "national" stations, chaos and confusion would result throughout the whole broadcast band, and listeners everywhere on the North American continent would suffer intolerable in- terference. Nobody would then be able to get good radio reception. RE-ALLOCATING 7300 STATIONS So an engineering allocation was made by an international committee of radio engineers to provide for all the 1300 North American broadcast transmitters — employing engineering standards of good service similar to those worked out by the Federal Com- munications Commission. That is, exclusive channels were to be provided for wide coverage of rural and isolated areas. And when sta- tions were to be assigned to share the same channel, adequate separation of distance was to be provided to pre- vent interference in each other's ser- vice areas. Under the broad international plan, Canada gets six exclusive channels, Mexico gets six, Cuba one, and the U. S. more than 40. Other channels are set up for high-power sharing be- tween two nations, at distance sepa- rations which will safeguard service to each. Under the reassignments the United States has had its number of chan- nels increased from 44 to 59, and it can use 15 additional channels under certain restrictions set out in the Treaty. On the other hand, its num- ber of regional channels has been re- duced from 42 to 41. GET READY TO GO AFTER BUSINESS These many shifts in broadcast sta- tion frequencies are scheduled to be carried out on Saturday, March 29, at 3 a.m. Radio dealers and radio service men should at once make plans to reach listeners with push button sets, to make these push button changes — to make sure that the job is done right and that the set owner, after March 29, will get the maximum volume and quality out of his favorite stations in their new positions. [f the resetting is not done cor- rectly, the listener may get badly im- paired reception after March 29, and lose the full musical quality and crispness of voice announcements, news bulletins and dramatic presenta- tions— if not lose them altogether. CHECK TUBES, PARTS, ANTENNAS And while push buttons are being reset, the service man should check tubes to see whether some may not be worn out and giving impaired reception. The service man too should check the antenna — gateway to all radio reception. If the set has an outdoor antenna, see whether winter storms, sleet and wind have impaired its pick-up qualities. If an indoor an- tenna, see if it is really adequate to bring good reception, without also bringing in a lot of electrical inter- ference. And if a loop antenna is being used see that it is turned cor- rectly for the stations most wanted. Check over volume controls and condensers, for noisy and worn-out parts. And if the customer is suffer- ing electrical interference, apply the necessary remedies. A splendid new period of radio re- ception is before American listeners as the result of the reallocation of March 29— Radio's "Moving Day." But you will want to plan now to be ready to do your part in going after the increased business which will re- sult by putting customers' push but- ton radios in first class operating con- dition for the new radio set-up. Cash In On the Big Push-Button Change Follow up all owners of push-button receivers, (including auto-radios). Reset push-buttons. Check their tubes. Look over antennas. Check noisy parts. Leave new radio-sets on trial with good prospects. Eliminate electrical interference. Collect your money.

A I HALF THE CARS . . . radio installed in your own car. Tell trie owner your story. Offer to fix him up while his car is in its down- town parking place — tell him you'll pick it up, install the set and return it, all radio equipped. Whenever you see a driver sitting in a radio-less car, step up to him, open a conversation, and ask him if he wouldn't be interested in listening to news and music as he sits there waiting. CARD REMINDERS IN EVERY RADIO-LESS CAR And have cards or folders printed to put into cars without radios which are parked at the curb all around your neighborhood. (Don't put the cards under the windshield wiper — that will irritate your prospect when he has to remove card in order to drive away.) Put the card on the front seat, where he can pick it up and read it at leisure. ...NEED RADIOS BIGGEST UNSATURATED MARKET FOR SETS TODAY IS "ON WHEELS" What is the greatest unsaturated market for radio left today ? Undoubt- edly, automobile radio. Just look out the window and watch the prospects for car-radios go by! Half the cars you see pass are real prospects for radio sales. Half the cars you see parked along the curb — or in any parking lot — have owners who want auto-radios right now, but "haven't got around to it." A lot of car owners, of course, have auto-radios already. And those who have 'em wouldn't do without 'em. (This is proven by the fact that second-hand auto radios are scarce as hen's teeth.) EIGHT MILLION HAVE 'EM Of all the cars on the road, taking the country as a whole — 8 million cars or about one-third the total already are radio equipped. They aren't pros- pects for radio set sales, now, it is true {but they are prospects for radio ser- vice maintenance and repairs.) Then there are a lot of old cars too far gone to be prospects for radio. Cross these out, of course. But you will find that left as real prospects — after subtracting the cars radio-equipped and the hopeless jalop- ies— are. about half the cars in regu- lar use. Ask these owners why they haven't a car radio. Hear the answers : "Oh yes, I've been intending to get a radio for my car but I just haven't gotten around to it." WHAT CAR OWNERS SAY "It takes a lot of time to put one in, I suppose, so, though I wanted a radio, I haven'j bothered." "I didn't know just who to go to, to get a car-radio installed." "Nobody ever offered to sell me a car-radio!" So here's the big opportunity for sales, installation and repairs waiting on a silver platter for radio men in every town. Hundreds of people within walking distance of your shop this very min- ute have a half-formed desire to have an automobile radio. They realize "it would be nice to have a radio in our old bus." But they don't know just how to go about getting it. And they don't know who to go to. So there's your cue, Mr. Badio Man. GO OUT AND TELL 'EM You go to them. Explain how easy it is to install a car radio — how little it costs to have all the enjoyment of news and music as they motor. Whenever you see a garage, make a call at that house with a sample car Watch for a time when the car manufacturers are plugging their new models in big-scale ads in your local newspapers, and make your auto set announcements in the same is- sues. (Most of the new cars may be radio-equipped, but anyway the in- terest in driving conveniences will be at a peak.) Arrange to distribute auto ra- dio fliers at places where large num- bers of cars are parked . . . football fields, race tracks, etc. Start with the "noise" aspect of car listening, in some of your pro- motions, both to emphasize the qual- ity of your units, and to get away from the usual accent on price. PUBLIC DEMONSTRATIONS Demonstrate your car radio on downtown streets when news events, special speeches or important events or baseball or football games are be- ing broadcast. People will be inter- ested in stopping to listen. And have a sign with your name and address, and a reminder — "A radio like this in- stalled in your car for $ Ask us about it. Bemember, one car out of every two that you see, is a hot prospect for a car-radio this spring. 20 MOJO TODAY RCA VICTROLA MODEL V-300 From the distinguished beauty of its cabinet down to the tiniest part in its chassis, this instrument is real quality.

That important fact is at one and the same time Kelvinator's#most valuable possession and the Kelvinator franchise holders' assurance of continuing and expanding profits. One by one Kelvinator has faced the problems of refrigerator and range retailers — haphazard step-up pricing — too many retailers — high prices — complacent engineering and product planning — too many models. And, one by one, Kelvinator has sought solutions. Fortunately for Kelvinator, this "attitude of mind" is perhaps the one thing in business that cannot be copied. It helps explain the fact that Kelvinator for 1941 is, any way you look at it — "the hot line — and the hot franchise". Kelvinator Division, N ASH-KELVIN ATOR CORPORATION, Detroit, Michigan Set KELVINATOR FEBRUARY, 1941 2 3 DEFENSE JOBS SPEED RADIO SALES (Continued from page 15) worth it. The record department has already been expanded. At Douglas Radio & Television Co., there's a very aggressive attitude. The report is that "business has picked up steadily" and "people seem to have more jobs." Manager G. W. Douglas likes to use other business people to get additional leads and prospects for radios. He keeps the store open till 9 p.m., has connected with a number of people who work in places where they contact the public. These places often close up earlier, and the "scouts" for Douglas are encouraged to bring their prospects and leads to the radio store before 9 p.m. SOUND PROMOTION These "part-time salesmen" get a fee for their pains, and they help the Douglas volume. This radio man also believes that more "demonstra- tor" radios should be scattered around in business houses who do not handle radios. He now has receivers spotted in five barber shops, with an accom- panying card to mention his store. The barbers are willing because cus- tomers like radio music, and Mr. Douglas knows of eight sets that have been sold as a result of the plan. He plans to double the number of radios thus selling themselves. He also has what seems to be a star idea for a program on the local station, plug- ging radio-recorders especially. The beforementioned Mr. Cannon of the Troup Music House strikes a note of caution, when asked how to locate and sell the people who are going back to work. He believes that many of these people will need time to "catch up" on financial obligations.

All sound Jobs are not associated with huge auditoriums, stadiums, and other few and far between locations. Many jobs are right around the corner from your place of business. Many times, the jobs won't know they are there, but some selling will show it to be the case. For example, there are probably three or four "gas" stations within a few blocks of your store. One or maybe two of them have washing or greasing racks in separate buildings, or at least in separate rooms. Here i is a real prospect for two-way inter-communication. The ex- tra convenience and greater speed In handling jobs will sell the system. - MP Sound systems are needed in busy in- dustrial plants. AUTOMOBILE JOBS Along in the automotive field are tlie garages, parking lots, taxi and bus centers which need calling, announc- ing, and inter-comm. systems. Parking-lot operators in particular have the problem of bringing cars in from the lot when they are called for by the owner at the lot office. Run- ning hack and forth between the far end of the field and the office is un- necessary when a two-way call system would allow an assistant to pick up the car whose license number is re- layed to him from the office. A typical parking lot system would consist of a 3 to 5-watt amplifier, mike with talk-listen switch, PM speaker for office, a PM speaker and weather- proof trumpet foi the far-end of the lot. "Wiring of course should be a a very good grade of weather proof cable. Keep it away from telephone, and power lines to avoid inductive 30 pick-up. The talk-listen switch can be a double pole double throw to switch the remote speaker from the amplifier output to the input transformer Traffic direction and control is another good field for the sound man Bridges, cross roads, viaducts, and busy intersections within the town need mobile or fixed PA units to speed the flow of cars, and avoid accidents. Mobile units such as the one shown in the Texas traffic control truck are typical of the types needed. These trucks are equipped and usually main- tained by the sound man. There are excellent profit opportunities in the initial sale of the equipment and the continued servicing of. the units. The truck shown was equipped by Olsen Radio Supply Co. of San An- tonio. An Erwood 20-watt amplifier with built-in phono turntable is used to- drive the Atlas speakers on the roof. It is used to patrol the streets and guard busy intersections against traffic violations. Bridges, toll roads, highway cross- over and intersections also need am- plifiers and speakers for routing traffic. The San Francisco-Oakland bridge uses a PA system to keep the passen- ger and commercial traffic properly separated and flowing over this largest of all spans. Atlas Sound Corp, exponential pro- jectors and PM drivers are mounted over the toll booths at the Oakland end of the bridge. These speakers are controlled by a police sergeant at a master traffic control station. Instruc- tions given the motorists guide them in entering the correct lanes. Further back from the bridge, on the approaches, another speaker di- rects the first division of the passenger. .. and truck traffic. Bridges, and other highway sections i which may bave use for this type of sound control, are usually under the control of county or city high-way de- partments. The best time to sell this type of job is during the construction stage. Traffic control engineers are. the ones to see about their plants for sound equipment. By working with them on the design and layout, the jobs can be sold. This' type of outdoor sound system' requires "plenty of- power, and equip- ment that will stand up under long, periods of. use. INDUSTRIAL SOUND Factories are excellent markets for complete sound systems. Added de- fense business has doubled and tripled man-power in many plants throughout the country. This extra personnel must be used efficiently, and sound fills a big order in helping with this job. A few of the things that sound can do in small plants and factories near you are as follows. 1. Speed office work and executive di- rection with complete, efficient two- way inter-communication among the firm heads. All of your local orchestras are excellent prospects for compact sound systems to be used as individual instrument amplifiers. Sell mikes, amplifiers, complete units. 2. Speed up production by using sound communication systems to place orders in the various departments route material through the manufac- turing processes, get tools and special equipment into the correct depart- ments, direct loading and crating of special and rush orders. 3. Save valuable man-hours by over- riding high machine noise levels with instructions, etc. 4. Sound systems can speed up the processes of delivery of raw materials and shipping of the finished products' by directing trucking in the un-Ioading and loading area. 5. Monotony of routine piece work may be alleviated by use of amplified music delivered in the working area by a PA system. 6. Employee recreation rooms need to be equipped with a PA system Game rooms, athletic fields are def- initely in the sound man's class. The factory picture shows a weath- er-proof speaker being used for giving yard instructions. LOCAL ORCHESTRA JOBS Every town has several aspiring bands who can use lots of PA equip- ment in the modern trend toward am- plified instruments. Many popular small orchestras use several amplifiers to boost the volume of the usually weak instruments, violins, and other stringed instruments. The band market needs amplifiers, mikes, speak- ers, contact mikes, special foot vol- ume controls, tubes, etc. Get the names of the leaders of these bands from the local sheet music store, newspaper, country-club officials or other social organization. Talk to these leaders, and let them try out in- dividual pick-up with foot type volume controlled amplifier on several of the instruments in the band. Sound systems for orchestras need to be the example of compactness, rug- gedness, and dependability. Lay out any system you plan to sell to or- chestras for the least number of con- trols, interconnections, and weight A job that will be self-contained is also easier to sell. Be sure that the mike, speaker, cables, and amplifier can all be quickly placed into a single con- venient case. RENTAL BUSINESS It is advisable to have some of the right types of sound systems for or- chestras available for renting. In this way, a band can try out the new effects of amplified instruments and sell them- selves the sound system. An accompanying photo shows the popular Russ Morgan band which fea- tures "Singing Strings." Stringed instruments were not for- merly featured in dance orchestras be- cause of the low volume of the sound they produced. However, with the use of contact mikes and amplifiers, they are now able to compete with the brass instruments. The more flexible vio- lins can produce many musical effects, which when amplified, become the main feature of the orchestra. The violinists shown in the Morgan band picture have Amperite Co. Kon- tak pick-up units clamped under the bridges of their instruments. OTHER JOBS NEAR A good many other jobs are near you and take only a little investigating to hunt them out. Suppose that the department store up the street is holding an anniversary sale, or any other sale. Go to the store manager and suggest using a sound system in the store to announce the various special bargains of the day and the floor on which the merchan- dise will be found. A rather simple Traffic control and safety campaign trucks are being used by many city police de- partments. Sound men can equip and maintain the system. Olsen Radio Co..

A local manufacturing plant is hav- ing a convention, for their representa- tives, etc. An inspection trip through the plant will certainly be a feature of the program. Here the sound man can rent an amplifier system to help the guide explain operations of machines and processes where the noise level makes ordinary conversation impos- sible. SELLING THE JOB The banquet and business sessions will also need a PA system for the speakers, entertainment, etc. Many similar everyday events offer real opportunities to the active sound man. By keeping up with these events and getting there first with the right system, will keep your sound business "humping."

Here, insignificant on his scratch pad, are the "doodles" of a radio engineer. . ."Doodles" that may well be the foundation of a highly significant development when RCA Research and team work have finished with them "Doodling" is a habit of thinkers. And that is why the scratch pads of radio engineers are often a pattern of "doodles." These men are ever thinking, probing, studying in their ceaseless ef- forts to uncover new radio devices and services. To this end, RCA Research plays an impor- tant part. The scores of outstanding develop- ments that have first seen the light of day in the RCA Laboratories are concrete proof of the progress research makes possible. In conducting research, RCA engi- neers and scientists have at their dispo- sal the greatest experience in electronics and sound. RCA is the only organization that makes and does everything in radio. Broadcasting problems frequently find solution in the experi- ence of the National Broadcasting Company . . . Communications problems are more easily solved with the assistance of R. C. A. Communications, Inc. . . .The answers to manufacturing problems may be secured through consultation with men at the RCA Manufacturing Company. . . Prob- lems encountered in marine radio development are overcome with the help of the Radiomarine Corporation of America. In short, the aid of the entire organization is extended to those in the RCA Laboratories who look to the future.

IT'S done nearly every day, in the Utah factory, as an extra precaution against transformer failure in the field. One of the most common causes of failure in ordinary transformers is due to inade- quate protection against moisture. In these torture chambers, Utah Transform- ers, encased in layers of specially made, mois- ture-resistant paper, are heated under a vacuum for hours. Thus, all of the air is safely removed from the paper and all of the moisture is evap- orated. Only then is the molten wax drawn into the vacuum tank and forced into the emptied cells of the paper under high pressure. As a result, an inter- layer insulation is obtained which is impervious to moisture. This is but one of the reasons why Utah Transformers have established such outstand- ing records, even under severe conditions. And why they offer you extra value.

THOSE FINE POINTS IN KEEPING YOUR RECORD PROFITS UP I'anicuiai success in the retail radio- phonograph business comes from pay- ing close attention to every detail. Every item in the music department should be merchandised. Not just the records and de luxe , combinations should get real sales effort, but the smaller essentials and accessories that With recorded music. And one of the details is the phono- graph needle. Some 75.000.000 records were wrapped up last year, and 900,- 000 phono-radio combinations were sold. The latter figure is double the total for last year. It's a trend, and one way to keep it going full blast is to give proper attention to the tiny point that rides in the groove of the record. In a new review of the needle busi- ness today, a number of "hints for dealers" are revealed. You start with the principles. A retailer should realize that what a customer may expect in a needle is (a) good reproduction, (b) minimum record wear, (c) low surface noise and (d) convenient durability. A record man should also be hep to a certain amount of technical informa- tion, such as the character of the rec- ord groove, the fundamental nature of point materials and metals used for needles, the significance of the polish and the shape of the needle, the impor- tance of the weight of the pickup, the angle at which the needle plays, etc. (Did you know that the record groove is about .065 in. across the top and .002 in. deep? Or that the needle travels about 595 ft. in playing a 10 in. record?) PROFITABLE POINTS He should likewise be aware of the methods used by his manufacturers to insure the uniformity of the needle point. For example, some are "Micro- spected" or "Shadowgraphed" at the factory as a positive check on the shape of the playing tip. Another requirement of the disc merchandiser is that he keep up-to- the-minute on developments released by the manufacturers in the field. New products and their customer-getting possibilities. Announcements on the replacement sales possibilities of the new lightweight pickups with perma- nent sapphire stylii, for instance, and the public interest created in the photo-electric record player — the "mu- sic on a beam of light" device. When people are interested in better equip- ment, that's the time to sell them— at a good profit. Dealers need, too, a demonstration routine that will illustrate to custom- ers the details of surface noise, worn needle points, record wear, etc. Some dealers, for example use magnfying glasses fo show prospects the point of a needle after a fixed number of play- ings. Some stores make a habit of using a good symphonic disc on which to demonstrate a number of different (Continued on page 48) FOR MODERN REPLACEMENTS • Here's new business . . . good business . . . easy to get. These pickups have so many advantages ... so many fine selling points . . . that only "low pressure" sell- ing is necessary to convince a customer of the wisdom of modernizing phonograph equipment with Astatic's New Low Pressure Crystal Pickup. With only one-ounce stylus pressure on the record, scarcely more than one-third the conventional weight, records will last a lifetime. Built-in, permanent sapphire stylus eliminates the necessity of ever changing needles, and reproduction is greatly improved with the elimination of surface noise and distortion. There's new business to be had! Every lover of recorded music, especially those possessing symphonic, operatic and other prized recordings is a potential customer. Depart- ment stores demonstrating records, schools desirous of prolonging the life of educational recordings, and many others, are all prospects for Low Pressure Pickup business.

Pacific Coast Servicemen Get Money-Making Hints Radio men on the West Coast were treated to a new series of illustrated addresses on profitable angles of ser- vicing last month when George C. Con- nor, Hygrade Sylvania commercial en- gineer, appeared there in the Cali- fornia, Washington and Oregon ses- sions of the Sylvania Service Schools. Of special interest to the service- men attending the Fresno and Oak- land, Calif., meeting, sponsored by DeJarnatt Wholesale Radio Parts Co., was the innovation of writing with fluorescent chalk on a white board by Mr. Connor to diagram wiring of radio circuits. The room was totally dark and the board illuminated by ultra violet ray beams. Meetings were sponsored by Syl- vania jobbers in each locality. The distributors were represented at the meetings by members of their respect- ive organizations, namely; Frank A. Nelson of the Frank A. Nelson Co., Paul Hanson of E. M.

GENERAL » ELECTRIC FEBRUARY, 1941 39 HOW TO RE-SET PUSH Simplified set-up procedure for six basic type of me- chanical and electro-mechanical push button systems. The "big shift" of radio push-buttons next month will bring into your hands a group of mechanical and electrical tuning systems which you have not worked with for some time. The fol- lowing diagrams and set-up directions will familiarize you with the popular mechanisms. Several general rules apply to set- ting-up of all push-button mechanisms. First, allow the set to warm-up for ten to twenty minutes before making any adjustments. During this time you Fig. 1 — Cam and lever mechanical sys- tem. Loosen cams, press button, tune in station, tighten cam lock. can clean the chassis and speaker, make a general inspection of the con- dition of the set and estimate any re- pair work if it is necessary. If a push- button alignment device is used, allow it to warm-up during the same period. USING YOUR OSCILLATOR Second, be sure the adjustments you make are secure and will not shift during continued use. This means careful re-checking of all set-ups by actually operating the mechanism sev- eral times. Screws, knobs, and other adjusting devices should be tight enough to hold their positions. Where it is necessary to reset push- buttons in advance of the March 29th change-over date, some standard fre- quency source will be necessary. One method which may be used is that of re-calibrating your signal generator for the broadcast band by beating its signal against the present known fre- quency broadcast stations which you can receive in your locality. Plot the dial readings of your signal generator against the frequencies of broadcast stations on the largest sheet of cross- sectioned paper you can get. Get as many points as possible as a check. The best time for this will be late in 40 the evening, when with a good receiver, plenty of known frequencies can be logged. Draw straight lines between the successive points where they are only a few kilocycles apart. Your re-calibrated oscillator should then be used to set-up a push-button alignment oscillator which will hold calibration over long periods of time. The^e are available from several man- ufacturers. It is important that every means of checking the frequencies should be used. Crystal controlled cal- ibrators which have numerous har- monics will also give a double check, usually at 100 kc. intervals. CAM AND LEVER TYPE This mechanical type of mechanism is usually found on the smaller table model sets with four buttons. It is characterized by a downward lever type action of the button. The cut- away view Fig. 1 shows the important parts of the tuner. The roller on a push-button lever (C) is pressed against its respective heart-shaped cam (B) when the button is moved downward. The pressure of the roller turns the cam to a "dip" or low point, thus tun- ing the gang condenser. To set-up these buttons; 1. loosen set screw or locking device on the cam shaft (A). 2. Press down any button for which an adjustment is to be made. 3. Man- ually tune in station to best position. 4. Set up other, buttons in similar man- ner. 5. Lock cams on shaft. Some receivers using the cam and lever system use the tuning knob and a gear system to "un-lock" the cams for adjustment. The knob is pressed inward until it engages the releasing mechanism, and is turned to the left until the cams can be adjusted. The station set-up procedure is the same, however. Other variations involve the locking of the cams with special screws or knobs. Another popular type uses a snap-in button in the dial escutcheon to cover a locking screw. Remove the button, and insert a screw driver. Press in, and turn locking screw to left until cams are free for adjustment. ROCKER BAR TYPE Another mechanical push-button tuner similar to the cam and lever type uses a rocker bar or plate attached to a sector gear which in turn drives the tuning condenser. Tuning to a par- ticular station is accomplished by pressing firmly on a button which has an arm-type cam attached at a partic- ular angle to the button rod. The cam pressing against the rocker bar tends to align it at the same angle thereby turning the condenser shaft to the pre- determined position. See the photo Fig. 2 of a typical mechanism. Springs are used to return the buttons to their normal "out" position after a station has been tuned. No change-over be- tween manual and button tuning is re- quired. The type of unit shown in Fig. 2 is set-up as follows. 1. Pull the push- button from the push arm. 2. Loosen the cam locking screw %-turn. 3. Us- ing the manual timing, select the de- Fig. 2 — Rocker-bar mechanical system is adjusted by loosening locking screws a half turn, pressing the push-button and holding it while tuning desired station manually, then locking the cam holding screw. Repeat for other buttons. CAM LOCKING SCREWS PUSH BUTTON LOCK SHOES CAM SPRINGS UTTONS Bired station carefully, I. Press In the push arm as far as it will go and ac- curately re-tune the station. 5. While holding the push-button down, tighten the cam locking screw. 6. Replace push-button knob and proceed to next button for set-up. OTHER ROCKER TYPES Other types of rocker bar assemblies have the cam locking screws integral with the button. The cams are released by turning the buttons counter-clock- wise 1J2 turns. The set-up is exactly the same as described above. The lock- ing screws on other types are exposed by removing the station name tabs from either the ends of the buttons or the escutcheon plate. Still others are located alongside the push rods and are exposed by removing the button trim plate or escutcheon. STATION SETTING CONTACTS INSULATION LINE BRASS SELECTOR DISC ( Fig. A — Electro-mechanical split selec- tor disc types adjusted by moving con- tact buttons 1, 2, 3, etc. TELEPHONE DIAL TYPES The revolving telephone dial-type tuner is another mechanical system which, uses stopping pins to return the gang condenser to its correct position. The diagram of Fig. 3 shows a cut- away view of this mechanism. The push-buttons are small spur gears with a crank-shaped pin fastened firmly to the inner end. The plate which holds the push buttons has mating teeth to hold the buttons in a particular posi- tion. A metal disc with a curved sec- tion cut from it to permit the removal of one button at a -time and a clamp- ing nut are the adjusting parts. When a button is pressed and the dial is rotated in either direction, the bent pin on the back of the depressed button comes to rest against a metal vane which acts as a stop. The gang condenser is attached to the dial mech- anism and is turned simultaneously. To set up the buttons for this mech- anism, proceed as follows. 1. Remove the bakelite cover plate by removing the large face nut in the center. 2. Put thin metal disc with circular notch on the hub of the dial and replace the face nut. This notched plate is used only to hold the buttons during set-up. FEBRUARY, 7947 Fig. 3 — Mechanical telephone dial type. Crank pin on each button is adjusted to stop dial and condenser at correct posi- tion when housing is turned. Tune station manually and set top button pin to vertical cen- ter line. Set button forward or backward one tooth at a time until station is tuned sharply. The springs back of the buttons may throw them out of the holding ring unless the set is tilted backward dur- ing the removal of the bakelite hous- ing. Notice that one hole is not used in the revolving plate. 3. Select the but- ton whose frequency range will include that of the station to be reset. 4. Care- fully rotate the thin notched plate after slightly loosening the face nut, until the notch is in line with the button to be adjusted. Hold each but- ton with your finger as the disc is moved by, or the button will spring out and lose its setting. 5. Manually tune the station to be set-up. The but- ton being set-up will be near the top of the housing. 6. Insert button so that the tip of the crank-pin is in line with the center of the metal vane. This is ap- proximately the same as the joint in the cabinet veneer. The large notch in the rim of the button locates the tip of the pin. See Fig. 3. The station must remain perfectly tuned during this op- eration. 7. Move the notched plate slightly to hold the button just set. 8. Check the set-up by dialing the sta- tion in both the clock-wise and counter- clock-wise directions. If the station is not sharply tuned-in, carefully move the button one tooth at a time until correct tuning is obtained. 9. Adjust the other buttons in the same manner. 10. Tilt the set backward, carefully re- move the notched metal plate and re- place the bakelite cover so that the blank space covers the unused hole in the button holder. Care must be used to prevent the buttons from springing out of the housing. SPLIT-SELECTOR DISC TYPE Two buttons with extra long crank- pins are sometimes used for reaching a particular station. These are used only where the short pins do not reach. It is important that the arm of the pin be either horizontal or pointing at some angle away from the hub (viewed when it has selected a station). This is nec- essary to prevent interference between the pins and other parts of the mecha- nism. Various electrical tuning mecha- nisms employ a metal disc attached to the condenser gang and tuning motor, which is divided into two insulated sections. A group of station contact buttons are adjustable in concentric semi-circular tracks. See Fig. 4 for a layout of this tuner. To set-up stations proceed as follows. 1. After the set has warmed up, press the "dial tuning" button and manually tune the lowest frequency station to be reset. 2. Hold down the dial tuning button and press the corresponding station button. Both will remain in. 3. Move the correct contact pin until it is directly on the narrow strip of insulation dividing the metal disc. The center dial lamp will go out when the contact is adjusted correctly. The contact buttons are counted from left to right when facing the back of the set. 4. Press down any other button to release the dial and button just set up. Pressing the button just adjusted will re-tune the station. 5. Proceed with the other buttons in the same manner. OTHER TYPES The divided selector disc should be adjusted so that the insulation line is horizontal with the dark material at the left end when the condenser is full meshed and viewed from the back of the set. Do this, if necessary, before adjusting the buttons. The Stewart-Warner "magic key- (Continued on page 42) Fig. 5 — Four steps in setting-up "mag- ic keyboard."

The best time for this will be late in CAMS ROCK! 40 MDIO TODAY HOW TO RE-SET PUSH- BUTTONS Simplified set-up procedure for six basic type of me- chanical and electro-mechanical push button systems. The "big shift" of radio push-buttons next month will bring into your hands a group of mechanical and electrical tuning systems which you have not worked with for some time. The fol- lowing diagrams and set-up directions will familiarize you with the popular mechanisms. Several general rules apply to set- ting-up of all push-button mechanisms. First, allow the set to warm-up for ten to twenty minutes before making any adjustments. During this time you Fig. 1 — Cam and lever mechanical sys- tem. Loosen cams, press button, tune in station, tighten cam lock. can clean the chassis and speaker, make a general inspection of the con- dition of the set and estimate any re- pair work if it is necessary. If a push- button alignment device is used, allow it to warm-up during the same period. USING YOUR OSCILLATOR Second, be sure the adjustments you make are secure and will not shift during continued use. This means careful re-checking of all set-ups by actually operating the mechanism sev- eral times. Screws, knobs, and other adjusting devices should be tight enough to hold their positions. Where it is necessary to reset push- buttons in advance of the March 29th change-over date, some standard fre- quency source will be necessary. One method which may be used Is that of re-calibrating your signal generator for the broadcast band by beating its signal against the present known fre- quency broadcast stations which you can receive in your locality. Plot the dial readings of your signal generator against the frequencies of broadcast stations on the largest sheet of cross- sectioned paper you can get. Get as many points as possible as a check. The best time for this will be late in I he evening, when with a good receiver, plenty of known frequencies can be logged. Draw straight lines between the successive points where they are only a few kilocycles apart. Your re-calibrated oscillator should then be used to set-up a push-button alignment oscillator which will hold calibration over long periods of time. The/se are available from several man- ufacturers. It is important that every means of checking the frequencies should be used. Crystal controlled cal- ibrators which have numerous har- monics will also give a double check, usually at 100 kc. intervals. CAM AND LEVER TYPE This mechanical type of mechanism is usually found on the smaller table model sets with four buttons. It is characterized by a downward lever type action of the button. The cut- away view Fig. 1 shows the important parts of the tuner. The roller on a push-button lever (C) is pressed against its respective heart-shaped cam (B) when the button is moved downward. The pressure of the roller turns the cam to a "dip" or low point, thus tun- ing the gang condenser. To set-up these buttons; 1. loosen set screw or locking device on the cam shaft (A). 2. Press down any button for which an adjustment is to be made. 3. Man- ually tune in station to best position. 4. Set up other, buttons in similar man- ner. 5. Lock cams on shaft. Some receivers using the cam and lever system use the tuning knob and a gear system to "un-lock" the cams for adjustment. The knob is pressed inward until it engages the releasing mechanism, and is turned to the left until the cams can be adjusted. The station set-up procedure is the same, however. Other variations involve the locking of the cams with special screws or knobs. Another popular type uses a snap-in button in the dial escutcheon to cover a locking screw. Remove the button, and insert a screw driver. Press in, and turn locking screw to left until cams are free for adjustment. ROCKER BAR TYPE Another mechanical push-button tuner similar to the cam and lever type uses a rocker bar or plate attached to a sector gear which in turn drives the tuning condenser. Tuning to a par- ticular station is accomplished by pressing firmly on a button which has an arm-type cam attached at a partic- ular angle to the button rod. The cam pressing against the rocker bar tends to align it at the same angle thereby turning the condenser shaft to the pre- determined position. See the photo Fig. 2 of a typical mechanism. Springs are used to return the huttons to their normal "out" position after a station has been tuned. No change-over be- tween manual and button tuning is re- quired. The type of unit shown in Fig. 2 is set-up as follows. 1. Pull the push- button from the push arm. 2. Loosen the cam locking screw %-turn. 3. Us- ing the manual tuning, select the de- Fig. 2 — Rocker-bar mechanical system is adjusted by loosening locking screws a half turn, pressing the push-button and holding it while tuning desired station manually, then locking the cam holding screw.

Press in the push arm as far as it will g0 and ac curately re-tune the station. 5 While holding the push-button down tighten the cam locking screw. 6. Replace push-button knob and proceed to next button for set-up. next OTHER ROCKER TYPES Other types of rocker bar assemblies have the cam locking screws integral with the button. The cams are released by turning the buttons counter-clock- wise l»/2 turns. The set-up is exactly the same as described above. The lock ing screws on other types are exposed by removing the station name tabs from either the ends of the buttons or the escutcheon plate. Still others are located alongside the push rods and are exposed by removing the button trim plate or escutcheon.

These are used only where the short pins do not reach. It is important that the arm of the pin be either horizontal or pointing at some angle away from the huh (viewed when it has selected a station).

Unlock mechanism, tune station, push knob in, pull out and lock mechanism. See text. 47 RE-SETTING PUSH BUTTONS {Continued from page 41) board" mechanism is a combination of electrical and mechanical units. To set-up the buttons, see Fig. 5 and pro- ceed as follows. 1. Remove the tuning knob by pulling it out from the panel and pull out the set-up knob on the same shaft as far as it will go. Rock the knob slightly to engage the gears. Turn the knob clockwise as far as it will go. During this operation, the dial pointer will move to the right and stop. The set-up knob is rotated about % of a turn beyond this point. 2. Push the button that is to be reset, being sure it is all the way in. Using the set-up knob, manually tune the de- sired station for best reception. This button is set as soon as another but- ton is pressed. Proceed to set the re- maining buttons by pressing each down and tuning the desired station. 3. To release the last button pressed, push the set-up knob on the tuning shaft back into the cabinet as far as it will go and then pull it out again, being sure to rock the knob to mesh the gears. 4. To lock the mechanism, turn the set-up knob counter clockwise un- til a definite stop is reached after the dial pointer moves to the left end of the scale. The set-up knob is pushed back in and the tuning knob replaced. This completes the set-up procedure. KEY AND DISC ELECTRIC TYPE The electric tuning mechanisms which travel to one end of the dial scale and then return to the desired station are usually arranged like the system of Fig. 6. Set up as follows. 1. Warm-up the set, put the range selector on standard broadcast, and the control knob to "Electric". 2. Press the first button to be set, and wait until the pointer stops. 3. Turn the control knob to "Manual". 4. Put the set-up pin into the adjustment strip above the selec- tor disc corresponding to the particular push-button. Be sure pin is well SWITCH ON CONDENSER GANG REVERSES MOTOR UPON REACHING! EITHER EXTREMITY down into the notch. 5. Tune the re- ceiver carefully to the desired station. 6. Remove the set-up pin. 7. Turn con- trol to "Electric". This button is now properly adjusted and the others may be set-up by holding the correct disc with the pin while tuning the station manually. The newer types of inductance and capacity trimming units for push-but- ton receivers are simple to re-adjust. The mica trimmers or iron cores are adjusted for best reception on the par- ticular station within their tuning range. The oscillator trimmer is ad- justed first, and then the detector and RF trimmers are peaked. Tube Failures in AC/DC Battery Portables Burned-out filaments in the tubes used with portables are one of the chief complaints in these sets. The ACj/DC, battery type in particular give trouble because of the usual surges in voltages common with half-wave rectifiers. The four, five, or six tubes are con- nected in series with a voltage drop- ping resistor across the output of the rectifier. A filter capacitor of 50 to 100 mfd. is connected across the series group of filaments. If one of the tube filaments burns out, the filter con- denser charges to approximately 150 volts. If a good tube is then installed, the 150 volts across 4 or 5 1.5 volt tubes will quickly burn-out one or more filaments. Even of the line power is off, the condenser may have sufficient charge to blow the tubes. CONDENSER FAILURE In some circuits, the high capacity condenser is of 10 or 25 volt rating in which case it will fail if one of the tubes burns out and allows the full rectified voltage to build up across it. If this condenser is out, it should be replaced with one capable of with- standing the full rectified voltage. Since the power tube is located at the positive end of the string to obtain bias, the plate and screen current from this tube would have to flow back through the filaments of the other tubes if a bleeder resistor to ground were not used. 1000 ohms is the usual value. The best type of circuit will have a bleeder resistor across the high capa- city condenser which will prevent a tube from being blown due to a high charge on the condenser. New tubes put in while the set is turned on the line power may not be protected how- ever. In any of the combination battery portables, the filament circuit should be studied so that you will know ex- actly what happens when tubes are removed or burned out. The set should be disconnected from the line and the filter capacitor shorted before any tubes are replaced. X REVERSING SWITCH MOTOR -GLAK ON CONDENSER GANG Push-button Tone Control on Zenith Models The Radiorgan tone control on many Zenith models is shown in the accom- panying diagram. A 6J5G is used as a diode second detector. A separate tri- ode is used as a audio driver. The six push-buttons give 65 different com- binations of tone. Closing switch A gives low bass. Switch B is "treble," C is for "voice," D closes is "normal," E is "alto," and F for "bass." The switches control the shunting across the volume control and the feedback from the plate circuit of the audio driver.

RCA Model 15BP Changes Better reproduction of the high fre- quencies will result if the RF by-pass capacitor across the first AF output is changed from 390 mmfd. to 100 mmfd. Cases of hum in this model can be reduced by putting a shield around the 1H5GT and securely grounding, or by adding a filter network to the plate circuit of that tube. Add a 100M ohm resistor in series with 1H5GT plate supply and by-pass the plate end of the new resistor to ground through 0.1 mfd. Dial cord slippage may be elim- inated by taking an extra turn around the drive shaft without lengthening the cord. 42 RADIO TODAY HERE'S A BIG SAVING for Any Serviceman Who Makes Frequent Volume Control Replacements WHAT IS IT?

Cook, owner of Cook Radio Service, 211 K St., Lincoln, Neb., en- dorses the idea of leaving a small set with the customer while the old set is being repaired. A satisfied customer is the best form of advertising says Mr. Cook, and the convenience of a loan set builds satisfaction. Cook has been in the radio game since 1928, and holds the ham license W9FWW. A photo of his service bench shows the handy outlets for 110 AC and 6 volts DC. A soldering iron heat control is also built into the rear bench strip. Antenna terminals and small drawers add to the convenience. Note the inclined test equipment panels. Plenty of work space and knee room add to the bench features. Typical Troubles Acratone 94 Oscillation Oscillation which is traced to the second RP circuit is easily remedied by turning the second RF coil at right angles to the antenna coil.

Banquet in the Lehigh Valley The Lehigh Valley Radio Service Association held their 3rd annual ban- quet late last month at the Hotel Allen, Allentown, Pa. Servicemen brought their friends to this big event which included, besides the dinner, prizes, favors, speakers, floor show, and dis- plays of test equipment by local job- bers. "TSK! TSK!" SAID ADAM HONEYMUG, THE WAY THEY FUSS ABOUT CONDENSERS!' Serviceman Adam Honeymug brushed a cobweb from beneath his chin, propped his feet more securely on the service bench and leaned back comfortably in his chair. "These parts manufacturers are screwy," he said to his wife, "Take the time I was up in North Adams, Mass., and dropped intotheSprague factory. The way those fel- lows fuss around, you'd think condensers were the most important part of ar radio set." "Yes, dear," replied his wife patiently. "That re- minds me. While you were over at the taproom, Mr. Jones called and said that condenser you put in his radio set had exploded. It scared the canary so it won't sing any more. He said if you didn't put in a good condenser this time, he'd come over here and kick your teeth in." "What's he griping about, anyway? Just because I picked up that condenser for 16c and it doesn't have any name on. he thinks it's no good. He's screwy, too." "Yes, dear." "Well, as I was saying, kid, you'd a died laughing up in North Adams. Just think of it! They've got about twenty engineers, doing nothin' but designing condensers. I could do it with my eyes shut." "I always said you were wonderful, dar. ling." "I could certainly show those birds how to reduce the cost of condensers. Why, when they make wet electrolytics, do you think they'd take faucet water? It's good enough for 'em to drink — but it ain't good enough to put in their condensers. They built a special dam up in the mountains and piped spring water Into the plant. They even distil that. They're screwy. I could . . . say, answer that 'phone, will ya." "It was the telephone company," ex- plained his wife a minute later. "They said they are cutting off our service until we pay our bill." "To heck with them," exclaimed Adam. "I don't need a 'phone much anyway. Well, as I was sayln', those guys up at Sprague spent about 'steen thousand dollars developin' f special machines to put the electrolytic formation on the aluminum foil used in dry electrolytics — just to make sure that every tiny bit of area was covered with the electrolyte. If they'd asked me, I'd a told 'em to paint it on with a brush." "But maybe that wouldn't be so good, dear." "Lissen, kid. I know what I'm talking about. Why, take the way they test con- densers. They got about a billion good-lookin' girls doin' nothing but testing. They test the condensers for everything — capacity, working voltage, surge voltage, leakage and series resist- ance and goodness knows what else. Think what that costs." "Yes, dear." "Yea, but that ain't the worst of it. They even throw the bad ones away. I offered to buy some for half price, but they said they wouldn't let me have 'em at ten times the regular price. They'd rather bust 'em up for junk than get real money for them. If that ain't screwy. Hey — what the . . ." "Oh, darling, the shop Is on fire. Call the fire department, quick!" "Huh, and give those screwy dopes down at the engine house a chance to wreck my business? Nothing doing. Let it burn. I don't much like this radio service racket anyhow." SPRAGUE PRODUCTS COMPANY North Adams, Mass. FEBRUARY, 7947 47 RECORDS AND RECORDERS FINE POINTS IN RECORD PROFITS (Continued from page 37) needles in succession, for comparison. When making comparative tests of needles, dealers should remember to take into consideration not only their own musical ear, but also that of the customer, which is most important in the final analysis. There should be also a display style in the store that will regularly empha- size quality needles. Display stunts may include diagrams of points and grooves, displays of pickups from man- ufacturers, illustrations of distorted music, etc. PROFIT SCHEDULE Finally, it is important to have an aggressive attitude toward "selling up" in needles. Don't be afraid to move up to more expensive needles or the quality pickups. Plenty of prospects want the convenience of 15,000 play- ings without a needle change and are willing to pay for it. The trend to automatic record changers helps this market because these changers are not really practical if the operator has to keep interrupting it to change the needle. For the market between the cheapest needles and the most expensive sap- phire ones, there are now available the needles whose average service is rated RECORDINGS Hymns, Sacred I'HUUfV Songs Attract n.W&% Church Patronage r SELECTED sacred and serai-sacred composi- tions— the favorites of millions. Meet the present amazing demand for selections of a serious type. Reproduced in acetate low- scratch materials. Advertised in an influential list of religious publications. Prospective customers for these records know what they want, and only perfected ren- ditions are necessary to sell them. It is also a fact that such renditions of sacred songs, hymns, suitable for all denominations, are ex- tremely rare. Equip yourself to meet this situation. You can — with profit. A number of these records are made espe- cially for musical towers or carillons — no scratch, two-sided acetate 12" transcriptions.

These retail at medium prices, well within reach of masses of record fans. An additional sales point: when you are trying to sell a quality needle, and have on your floor an expensive com- bination which comes equipped with it, be sure to point out that the needle is the choice of leading manufacturers. It will help. It is reported that in Dayton, Ohio, one aggressive radio dealer is offering permanent jewel needles with his com- binations, and bringing the customers in! He's using large newspaper space to plug the deal, and he's making plenty of sales. This action illustrates how new needles can be used as a fresh way to attract buyers. Hammermill Paper Goes in for Discs New entry into the business of manufacturing blank discs for home recording is the Hammermill Paper Co., Plastics Division, Erie, Pa. A complete line of blanks will be sold through jobbers and dealers; the Hammermill disc comes in 6", 8", and 10" sizes, complete with dealer dis- plays. Walco Has Lower Price on Sapphires A price reduction of 30 per cent on Walco sapphire phonograph needles has been announced by Electrovox Co., 424 Madison Avenue, New York City. The list price for the jewel needles is now $1, with full trade discounts applying. Electrovox says that the new price is made possible by "a vast production increase brought about by adoption of Walco needles as standard equipment on new phonographs of leading manu- facturers." Walco execs point out that the widespread interest in light-weight pickups with permanent jewel points has made the 1941 sales theme, "No More Needles to Change." The idea is being vigorously promoted by lead- ing makers of new combinations and Walco sees "a tremendous sales in- Good Sales Bets Among New Discs WILL BRADLEY and his orchestra playing 3 Ring Ragout — Columbia 35871.
