BOARD IS WORKING ON GHAIN PROBLEM Synchronization Suggested as Possible Solution of . ‘Radio Question. A plan which would virtually make the proposed prohibition of chain broadcasting within 200 miles area un- ¢ necessary is being sought vainly by prominent engineers and members of | the Federal Radio Commission. It is| apparent that a solution to the problem is wanted before the regulation. which would cut the size of networks into ap- | Pproximately one-half, becomes effective on February 1. | On September 8 the radio body issued | @n order simultaneously with the new | allocation plan which would prohibit | duplication of netwerk programs within 300 mile area. Stations affiliated with the networks and thousands of listeners | registered sharp protest to this regula- | tion. with the result the commission | postponed the effectiveness of this order | until February 1. It was announced that this temporary retraction would give the board further time to conslderi the plausibility of the plan before mak- | ing a decision. | Board Considering Plan. | It is reported that the commission is considering several. plans which would | golve the chajn program situation. The | board’s original intention was to apply this regulation only to stations operat- ing on exclusive channels, the idea be- | ing, of course, to give greater service to | listeners throughout the country. It| was argued at the time the commission decided upon the regulation that the | average set owner is able to receive less than a half dozen programs under ordi- nary conditions, and under present chain conditions 50 per cent would be duplications. Under the present allocation of wave Jengths there are 28 stations operating full time on exclusive channels and 12 others operating cleared bands on a time-sharing basis. Of these stations, more than 70 per cent are affiliated with chains, and this is the situation which the commission seeks to alter. Despite numerous allegations from smaller broadcasters, perhaps none too ‘well treated under the new allocation, the commission claims that partiality has not been shown to chain stations. It merely happened, according to the commission, that the gountry’s best stations, serving the greatest number of listeners, are members of mnetworks. ‘The commission in making the assign- ment chose those stations serving best in “public interest, convenience or ne- cessity” for the most desirable wave lengths and power allotments. With only a few exceptions, broadcasters af- filiated with networks are not owned by the chains, but the managers of the stations themselves chose to join the country-wide systems. Order Will Limit Chains. If the commission’s order becomes effective on February 1, present chains will be allowed.only one hour during the evening. It has been reported in official radio circles, however, that the board in proposing_the chain limita- tions seeks to have the broadcasting ompanies precipitdte some plan of so- ion before the orders becomes effec- ive. Despite this assumption, none of | the broadcasting organizations has men- tioned any arbitrary solution, but in stead have sought to have the com-; mission retract the general order. ‘The commission’s object in clearing 40 channels in the broadcasting spec- jority -ef these station broadcast pro- grams originating from the same studio, nothing has been accomplished by the commission plan. < + Suggests'Board Regulate Claim,” _ One prominent engineer suggests that chains be allowed to continue under the jurisdiction of the commission. Hdwever, the commission so far has not made any recommendations to the broadcasting companies. Under exist- ing conditions, the matter of joining a network is entirely up to the owners and operators of the broadcasting sta- tion. It is interesting to note, how- ever, that a number of the stations re- cel power or better wave- lengths during the past year have sought affiliation with the networks after the assignment had been granted. One instance of this is WEBC, at Su- perior, Wis. The commission granted this station a power increase last Sum- mer, in order that the President might listen to broadcasting while sojourning &t Cedar Island Lodge, near Superior. Soon after, the station affiliated with one of the larger networks. . Without doubt the chain programs are extremely popular with radio lis- teners. This was evidenced by the num- ber of protests received by the commis- sion and radio experts following the announcement of the chain crder, and it is largely because of these protests that the commission decided to post- pone “the regulation until February 1. Synchronization May -Be Solution Probably the most plausible solution to the chain problem would be the syn- chronization of the network stations, allowing them all to operate on the same channel. With chain stations all operating on the same wavelength there would be no waste of channels, and the network programs would be al- Jowed to continue with possibly in- creased service areas. ‘The main obstacle in the synchroni- gation plan is still undeveloped. Some engineers, favor the scheme, while others. denounce it as being entirely impracti- cable. However, it has been tried and WO successfully with two stations. ‘Whether it will be developed to the stage where ‘more than two stations may operate successfully on the same wavelength awaits the research of radio engineers. This system is now func- tioning satisfactorily in the case of {Co. are the leading applicants for the SHORT WAVE FIGHT NEAR SETTLEMENT Federal Radio Commission| Soon Will Announce Com- mercial Allocations. ‘The smoke-screen that has enveloped the whole subject of the allocation of short waves for commercial use is about to rise. Behind closed doors, and with utmost secrecy the Federal Radio Com~ mission has been deliberating this vital matter, to determine who shall get the largest slices of this virgin radio ierri- tory, and just what character of radio service will be permitted. Decision will be made shortly, even though things are not entirely serene within the commission as to which of the major applications should be granted; these relate primarily to the setting up of radio-telegraph networks within the United States that would parallel existing land wire servicés, and transact message business by radn in the same manner as the Western Union and Postal do their telegraphic business. There actually are hundreds of other applications pending for short wave channels- in. the continental band, but the message services and the policy that must be adopted in that connection are of major importance. Leading Applicants for Service. ‘The Radio Corporation of America, the Postal Radio & Telegraph Co., and the Uniyersal Wireless Communications Thessage sérvice. Each asks for between 30 and 40 of these channels, and it is not yet decided whether any will be granted, although the trend is for the establishment of one, and only one such service. . The Universal Co. is a new- comer in the radio field, but is said to have “heavy financial support, well equipped experimental laboratories, a vast number of patents that are par- ticularly adaptable for message work, and, lastly, the support, of some mem- bers of “the commission—perhaps a mejority, | There has beep an inkling of doubt | on the part of some members of the | commission as to the propriety of licensing for the radio message networks as public utilities, either the RCA or the postal groups. This develops be- cause of the terms of the radio act, regarding radio holdings by a company that has interests either in cable or telegraph utilities, in the case of the postal group, and because of the anti- monopoly laws as regards the RCA. These are matters being debated, but near conclusion, and matters that may tend toward the application of the uni- versal group. The sudden and quiet manner in which the commission has begun con- sideration of the short-wave allocation has been somewhat surprising. This is in view of the fact that it heretofore has held in abeyance any consideration | of commercial allocation until some definite arrangement with Canada, Cuba and Mexico had been reached as to the distribution between the countries of these channels. Canada, so far as is officially and publicly known, has refused to negotiate with the Unifed Btates on short waves unless it is u: anteed 50 per cent of the total num- ber of channels, on an equal basis with this country. WBZ and WBZA at Springfield and Boston, respectively. When engineers | found that it was impossible to hear | the signals of WBZ in Boston several | years ago a solution to the problem wa | ought. It was finally decided to try chronization, and since then has | operating successfully. | he prime factor in the operating of two or more stations on the same wave- | length is that their frequencies be iden- | tical to the fraction of a cycle. The| reason for the necessity of this extreme | precision is to prevent hererodyning in- | terference, which would result in a| high-pitched whistle equal to the dif- ference in the two frequencies. It is believed in official radio circles | that the comumission will make some | reconsideration on the chain regulation before February 1. No definite solution to the problem has been proffered by either members of the commission or broadcasting companies. Chain pro- grams are so popular with listeners that | it is believed some plausible plan which | would allow their continuance will be forthcoming before the date set by the commission for the prohibiting of sta- tion tie-ups within the 300-mile radii. Bicycle Advertising Barred. PARIS (#.—An organizer of radio concerts in Paris submitted his program to the authorities, in conformity with the regulations.

MEXICO CITY (#).—The govern- ment has instelled a powerful radio | statfon on Chapultepec Heights, over- looking the city, by which it plans to maintain a regular public communica- tions service with practically all parts of the ‘world. On tests contact was fade with Burope and Asia, A conference was to have been held in Ottawa early in' November to con- summate the “gentleman’s agreement” between .the several American _coun- tries that would have given Canada approximately one channel to each four for the United States. But Canada re- fused even to hold the conference un- less the principle of 50-50 divison was | agreed to by the United States. Now it is felt that perhaps some tentative understanding has been made | with Canada and that a conference jater will be held to consummate a new “gentleman’s agreement.” This infer- ence is drawn by the fact that the commission is at work on the matter of allccating waves to applicants even before it knows how many channels it will get. Yet another factor is that the in- ternational radiotelegraph treaty goes | into effect on January 1, and in the reassignment of wave lengths among | nations under that treaty, the commis- | sion must lay down a rule regarding | the public service to be rendered by | companies assigned to use the short waves, (Copyright. 1928. by the Consolidated Press.) | Beads Cause Disturbance.

They get me on the air, and I sup- pose-that’s ‘why so many:of them lay a-~coursé in my direction. At first they almost ate me up, like a plague of red ants, and 1 was always dodging down back stairways, or sending word by the office boy that I had broken my leg and would be in bed for two or three years, or something like that. As it is now, our company has a pretty sizeable plant, with many elevators and private rooms, and one has a much better chance of escape. Mr. Giddings, our efficient program director, has things weil in hand, but I always find myself arriving and departing more or less furtively, with an anxiqus sideways 100k. My fears are justified. Most of these people lie in wait like a submarine,.and they sink you sooner or later. There' was one big, strong lunged chap, with spats, a circus overcoat and a big rock in his necktie, who was after me for six months.

Invaders Vary in Type. Many, of the invaders, like this one, can instantly pegged as nothing worse than a nuisance, and disposed of as gently as possible. Others are not so easy to pigeonhole, and their type requires continued alertness on the part of the program director. Frequently they have letters of introduction from persons - worthy of consideration—how they get them I don’t know. ‘The visitor is an_expert analyst of stocks and bonds. He has some record which sounds plausible. He is not par- ticularly interested in any monetary re- turns, but there is such urgent need for dependable information, with the publig investing heavily, that he belies a short, concise daily analysis of the market would be a splendid feature on the air.

The program director has to dis- illusion her as tactfully as possible. The Wheat and the Chaff.: There is a bit of pathot in these cases, but any honest or ambitious young person wanting to do something for the radio, may always be sure of a sym- pathetic hearing. In spite of his neces- sary - watchfulness for cranks and frauds, the program director is always hospitable to real talent and to real ideas. There is always a place. for these in_radio, and when I see the amazing }dmv raish of bilk and bilge into broad- casting studios, I conclude that the broadcasters are performing marvelous- liv a most djfficult task in throwing up "the flag against ‘all this'dnd putting out fine musical, educational and gen- eral entertainment programs.

Scramble for Waves. Early in 1928 business gave sudden recognition to ‘the new importance of radio and there was a scramble of com- | mercial enterprises for.the short-wave channels. The radio telephone traffic between the United States and Europe increased greatly and new links were established. Radio again demonstrated its value in expediting rescue and relief. When the St. Francis Dam broke in Cali- fornia amateurs flashed the. first news of th catastrophe and helped in the organization of relief. In the Porto Rico and Florida hurricane amateur and other operators also gave aid. Radio was used by Gen. Nobile in the navigation of his dirigible on_ his ill- fated flight to the north polar regions and played an important part in the rescue of his party. The record flight of the Southern Cross from San Fran- cisco to Australia demonstrated the ef- fectiveness of the radio beacon and compass. S 0 S Saves Courtney. An S O S sent by Capt.

Radio Answers Representative questions are se- lected each week from the queries of radio fans and will be answered col- lectively through this series by lead- ing radio engineers. In this way most accurate and authoritative so- lutions to every-day radio problems are assured to our readers. THE QUESTIONS: Can AC tubes give amplification com- parable to that obtained with DC tubes? What methods are used to climinate | hum? What type of AC tube is most | generally satisfactory? A comparison of the three important alectrical constants possessed by vacuum | valves or tubes shows the superiority of the AC valve as an amplifier. With | respect to amplification factor, the —26 | type shows an increase of 5 per cent |and the —27 type shows an increase | of 11 per cent over the —01A type of tube. With respect to plate impedance, at the usual plate potential of 90 volts, | the —26 is 15 per cent lower than the | —01A and the 327 is 9 per cent lower. The average mutual conductance val of the —26 and the —27 at 90 volts | plate potential is approximately 22.3 per cent more than that of the —O01A. High amplification factor, low plate im. { pedance and high mutual conductance | are conducive to greater amplifica- | tion. They affect total receiver output | volume and tone quality, the first and third increasing volume and the sec- ond improving quality by permitting beiter low frequency transfer between the vacuum valve and the coupling unit. ‘The methods of “hum” elimination | or minimization are' numerous. Correct | electrical balance in the filament cir- | cuit is of great importance, particularly in the case of the —26 type. This elec- trical balance is the correct location of the tap on the-transformer primary | or the resistance shunting the filament. | This tap is the grid and plate circuit | return, and correct location greatly | minimizes the voltage ripple or hum. | Correct plate and grid voltages likewise minimize hum, although these poten- tials are not of such great importance in the case of the —27 tube. In the 26 type, however, they manifest a great influence and govern the suc- cessful utility of this valve. Elimination { of coupling between the AC filament circuit and remainder of the receiver minimizes hum. The application of cor- {rect grid potential is influential. The correct location of the center tap of | the filament winding and the by-pass- ing of all bias resistance are likewise of importance. | The —27 type of vacuum valve, em- | ploying a cathode as the source of electrens and the filament as a simple | heater, is the most satisfacto: | reasons ere numerous. In the first | place filament circuit unbalance di | plays little effect. Secon: and plate current values are not critical. Third, the AC filament is not a part of the grid and plate circuit, and dis- turbances in the filament circuit do not | affect the other two circuits, conse- quently hum from this source is greatly minimized. All of the above combine to permit greater and easier adaptation and less critical operation. FAR WEST HOOK-UP BEGINS TOMORROW N. B. C. to Open First Permanent Coast-to-Coast Radio Span. The Pacific Coast will be permanently | linked in the nation-wide radio net- work of the National Broadcasting Co. | at 9:30 o'clock tomorrow night, when & 24-hour program circult from Den- | ver to San Prancisco will be hooked up | for coast-to-coastdistribution of pro- |grams. The final link in the perma- | nent_circuit required intensive work for more than a year, and is the final operation in connecting by specially engineered wires and 58 stations asso- | lated with the National Broadcasting | Co. | The first span in this transconti- | nental link was completed June when the line was extended from Omaha to Denver. Maintenance of the permanent circuit will cost the | National Broadcasting Co. $220.000 a | year, it is said. Sticcessful installation of this cir- cuit is regarded by engineers as an achievement of first magnitude. They recall that the first telephone ecircuit from New York to San Francisco was not completed until 1915, and out that it is comparatively simple to install telephone circuits in comparison to permanent specially engineered lines carrying musical tone. ~Experiments were made for 18 months before the 2.200-mile circuit was ready. Exten- sive tests were made to assure uniform transmission of programs to and from the coast. ‘This new circiit serves two interme- | diate transmitters, KSL, Salt Lake City, {and KOA, Denver, and enables the Na- | tional Broadcasting Co. to provide the ;l‘ntlr? country. with its network pro- grams, 1, RADIO GROUP TO MEET, | Institute of Engineers to Hold Session May 13 to 15.
