BROADCAST GAME VIEWEDBY EXPERT “Carl H. Butman Discusses Possibilities Relating to Wave-Length Changes. BY CARL H. BUTMAN. Instead of twirling our tween the & and the 200 meter marks, within a yvear or two we may be tuning in stations on 120 or even )0 meters. Many experts and ex- ponents of the broadcasting game be- lieve the future development of hroadcasting, lies in the use of (g1 paratively short wave lengths, oper ating below the present broadcast hands, with greatly reduced power. But there are many experiments vet to be completed and their results studied. besides which broadeast re- ceiving sets must be modified, to tune in_the lower wave lengths In any event the extension of the hand assigned to broadeasting down- ward would make it possible for sta- tions iwaiting _an available channel to open up. It would make room for many more stations on the r. The lower we go in wave ngths, the more broadcast chan- nels can be ovened; because, as wave lengths decrease in meters, the sepa- ration between the channels in kilo cyeles becomes greater. Between 200 d 150 meters, for example, there are 500 kilocycles, making possible 50 separate channels, 10 kilocycles apart. whereas between 150 and 100 meters there are 1,000 kilocycles, giv Ing approximately twice many channels. View as to Class A Stations. Some radio experts believe the present class A stations, particu larly those on the shorter wave lengths, will be in a better position for broadcasting in a year or two, if they hold their assigned channels than some of the more powerful class B stations on the higher wave lengths. Recent demonstrations with the shorter wave lengths indicate their greater practical value and show that less power is required to pro- Ject signals to great distances. Be- sides this, the short waves seem to override static better than the higher waves, Not long ago the old amateur band between 200 and 220 meters was as signed for use in radio-phone broad- casting, where it was badly needed The amateurs were very decent, but lost nothing. as their recent activity on shorter waves has proven. Many of them went down to around 80, 40 and 20 meters, where they now oper- ate to great distances with less power and marked success. The Navy and other experimental researchers have also been successful in operating on wave lengths between 70 and 20 me- ters, even in davlight. But today these short channels, or high fre quencies, would not be suitable for broadcasting, as the signals have a tendency to disappear at certain dis- tances from their source, uncannily reappearing again at further away. Broadcasting of necessity should serve in all directions equally well and at all distances up to a station's limiting range. A study of very that dials be- | | | I\ short waves 1s essential before they can be applied to this phase of radio- telephony, ‘but the study is going orward Field of Probable Extension. In the band lying just below present broadcast band, which is wow used to any great extent by amateurs, lles the field where the probable extension of broadcasting rights of way will first be found. Manufacturers of broadcast receiy- ing sets will of course develop and produce receivers which will reach to these lower levels. Few such sets today operate efficiently even at 200 meters, although WIBD at Joliet, TIl., is on that wave length. It is of course now useless to broadcast on wave lengths below that figure. However, it no great problem to design new receivers or modify the present sets so as to extend the limits of reception down to even 100 meters. The amateurs have already improved their receivers, through their own efforts. Although today prospective broad- casters are clamoring for long wave lengths, around 400 meters or above, and also for high power, in the very near future it will be found that quite short waves with only mod- erate pover will prove more prac tical and economical. Therefore, the class A waves soon will be in great demand and probably will become as scarce as the class B channels are today. the not LOW POWER FEAT London Receipt of Connecticut Message Believed Record. LONDON, May 1 R. W. H. Blox- am of ckheath, an amateur radio enthusiast, successfully intercepted recently d: ight signals transmitted by John L. Reinartz from South Man- chester, Conn., on a wave length of 20 meters. The Royal Geographical So- ciety estimates the distance at 3,334 miles, and reception, it is believed, constitutes daylight record for the Jow power used. The power utilized in sending was one kilowatt, which is less than that consumed by an ordinary domestic electrio heating radiator. The receiver used Py Bloxum was a standard two- valve set, but with special tuning ar- rangéthents for 20.meter reception . Permits Anthem, Is Fined.

PIGEONS BRING REPORT OF EXPOSITION OPENING IFirst Event Devoted Exclusively to Travel and Entertainment Features Held in Munich. By the Associated Press. MUNICH, May 3$0.—Fifteen hun- dred carrier pigeons today flew from Munick to Frankfort with the news of the opening of the German traffic and communications exposition, said to be the first of its kind devoted exclusively to tne demonstration of the science of travel and communi- cation. The opening ceremonies were at- tended by Dr. Otto Gessler, minister of defense, and other members of the cabinet; Premier Held and the BaVva- rian cabinet, and by representatives of foreign countries. The carrier pigeons were loaned by the Frankfort Bird Fanciers' Society. After Dbeing released from wicker cages the birds circled over the ex- position for a few seconds and then winged their way toward Frankfort, where they arrived this afternoon at 6 o'clock. The distance is about 200 miles. The exposition. which is sponsored by the federal government and by the German states, will remain un- DAY STAR, WASHINGTON, WOMAN Miss Grace Hazen, assistant physicist at the Bureau of Standards and one of the few women in the count sion.

Thus radio is making for greater perspective of those who profess a belief in God, and enlightening those who fall to do so. Practically every other broadcaster in the country transmits regularly or occasionally from one or more churches. All told, there are chur licensed to broadcast, as well eral stations operated privately ministers and divines, and some or- ganizations like the Y. M. C. A. This is a very small percentage out of more than 236,000 churches located in the United States, but is representative. The broadcasting of religious talks and doctrines takes place in 26 States, benefiting church members who can not attend, and also unattached indi viduals. Numerically, hes ev by the Baptists lead, ating broadcasting stations. while the Presbyterfans follow with 9: the Episcopalians and Methodists have 5 each, and the Congregationalists Christian and Methodist-Episcopalians 4 each. The 13 other denominations are represented on the air by 1 or 2 stations. In some communities broadcasting stations are operated for all or sev. eral churches, in rotation. The Chri tian churches of Little Rock, Ark., own stations KFMB, and the United churches of Olympia, Wash., operate KFRW. In St. Louis many churches broadcast through the Truth Center. station KFWF. In Washington WCA transmits services for 13 churches, including a Catholic and a Christian Science Church, the sequence being arranged by the Federation of Churches. Besides the churches proper, the Bible Institute of Los Angeles broad. casts from KJS, and the People’s Pul- pit Association operates stations in Brooklyn, N. Y., and Batavia, 1ll. Y M. C. A. stations are located in Vir- ginia, Minnesota, and in Pawtucket, R. I As far as is recorded in the De- partment of Commerce files, there ap- pear to be no stations owned or op- erated by either the Catholics or the Christian Scientists, although local churches are known to have broad- cast their services through privately owned stations.~ In New York the Paulist Fathers have applied for a broadcasting license and await a wave length. For the first time in history a mi crophone was recently installed in St. Peter's, at Rome, and the ceremonies, including a speech by the Pope, were broadcast. Incidentally, by means of loud-speakers all the people in the great edifice heard the ceremonies distinctly probably for the first time. Almost all religious faiths are going on the air, somewhere in the country, and if they continue to preach their doctrines fearlessly and in an un- biased manner, many listeners feel that religion will come to have an im- portant part in every fan's life. Cer- tainly sufficient creeds are offering ceremonles so that every non-church- man can select one, if he desires. This muitiplicity of creeds available to the fans makes it possible for every one to secure at least a fair idea of the elements of each religion, and should tend toward giving listen- ers a better understanding of religion in general and eventually human Thousands more attend services via the air than go to church in person. \per- Giant Speaker for Radio Show. The largest loud-speaker in the world will have its public debut at the forthcoming second annual radio show, to be conducted by the Radio Merchants' Association October 5 to 11. The glant speaker is the latest de- velopment of the Radio Corporation of America’s laboratories, and is designed to supersede the public address tem of amplification now in general use in auditoriums throughout the country. Instead of a number of horns scat tered through the building, as in the present method, but one horn will be used in the new R. C. A. system. This horn, it is said, has a carrying range of from 5 feet to 5 miles with per- fect clarity. Policing the Air. Before broadcasting commercial ma- terial, either advertising or publicity matser, the National Vigilance Com- mittee of the Associated Advertising Clubs of the World suggests that sta- tions be sure the copy or text is not only interesting but true, and also that the advertiser is reputable. When broadcasting such programs it also Is requested that station announcers tell the listeners in advance what they are about to hear. While this organization finds most radio broadcasting stations have adopted and maintained a high stand- ard of requirements as to material transmitted, they find that some sta- tion managers have occasionally failed to fully safeguard their own popular- ity and good reputation which this use of the air must maintain if the broadcasting is to be commercially | effective or aid in paying for the costs of broadcasting. Studio facili- ties here and there, a recent report from the vigilance committee states, have been made accessible to adver- tisers whose copy would not be ac- cepted by first-class newspapers and magazines. Possibly, they believe, some self-styled “doctors,” for exam ple, who have found other advertis- ing channels closed to their copy, are seeking this new medium of reaching the public. Several broadcast efforts of this type prepared in imitation of bona fide financial, health or technical talks have added little to the reputa- tion of the stations used, the report states. Other stations when offered apparently safe material by unknown concerns ‘have discovered, when they consulted the Better Business Bu- reaus or the vigilance committee, that either the material or prospective client was undesirable. The committee also suggests that it is necessary to quote frankly the source and purpose of all commercial ‘broadcasts so that the fans will know RADIO ENGINEER ting sets is further restricted by the!

For several months the interdepartmental radio advisory committee has been working on a draft of this plan for regulating radio trafc and routine matters within the several departments of the Govern- ment, but the completed text, as ap- proved by representatives of the State Navy, War, Post Office, Treasury and Commerce departments, has just been sent to the chief co-ordinator for final examination. If it receives an 0. K. in his office, it is understood that Gen. Lord will hand it to the President within a week's time. Although this plan does notiaffect commercial, amateur or private radio broadcasting. it is nevertheless of con- siderable general interest, since it outlines the attitude of the Govern- ment upon the operation of national radio circuits, and makes for stand- ardization and co-operation of Gov- ernment-operated radio stations owned by the Army, Navy, Post Office and Coast Guard. Radio Artists on Stage. Many radio artists have stepped from the stage to the microphone, but station WKRC at Cincinnati is put ting forth the first vaudeville troupe to step directly from the microphone to the stage. “Doc Howard's WKRC Broadeasters,” who present a regu lar Monday night program and ap- pearing again every Tuesday night with orchestra, male quartet, charac- ter singers and whistlers. goes into vaudeville this Summer billed as “‘the WKRC Broadcasters™ and are already booked in theaters throughout the country A motion picture is used in the act, showing a family group listening to & radio program from WKRC.

Mittendorf introduces Doc Howard and his_entertainers on the silver screen. and then the film fades out, enabling the curtain to lift, show- ing the stage fitted out as a studio with microphone, etc., and the vaude- ville act is under way. Signal lights and the general studio theme is car- ried out in the act, with Doc Howard announcing -each number on the pro. gram into the microphone, presenting a unique treat for the audfence to enjoy. Broadcasting Popular in Japan. Japanese radio fans are applying for receiving licenses at the rate of about 1,500 per week since broadcasting be- gan, the Department of Commerce is advised. Applications for permits received by the Osaka radio broadcasting bureau between March 15 and May 1 total over 10,000. Importers of radio sets believe even more sets wiil be in use, as many persons will be tempted to operate unlicensed sets to avoid the tax. The demand for radio apparatus of certain makes has exhausted the sup- ply in Osaka and Kobe. One large American exporter. who has already disposed of 12,000 tubes in Japan, is sending another 20,000 shipment. A Japanese firm in Osaka, reported to be manufacturing 500 receiving sets a month, is steadily running behind on deliveries. Broadcasting in Japan is vet in its first stage of development. It was on March 3, 1925, that the Japanese gov- ernment’ authorized the Osaka radio broadcasting bureau to operate the first public broadcasting station in the district and the third in Japan. The others are operating in Tokio and Nagoya. The Osaka bureau charges approximately 75 cents a month against owners of receiving sets living within 100 miles. In addition a flat tax of about $1 is levied on each set by the government. The use of receiv- government to approved types of one and two tube regenerating models.

No. 18—From Radio to Audio. Smith is ona of those rare persons who always manage to take advan- tage of disadvantage. There are some nights when reception i not so good. or times when he doesn't like what he can get over the air, but instead of grumbling he recognizes the chance to learn something more about how the set works It was at one of those eventful occ: sions that I happened to find him tr ing to trace the radio circuits from imput to output. The various basic units of the set were becoming as fa miliar to him as the arrangement of engine, clutch, transmission and dif ferential in his car. He had formed a definite mental picture of the order from aerial to tuner, to radio frequen cy amplifier tubes. to detector, to audio amplifief tubes and to loud speaker, but it was that changeover from radio to audio that still puzzied him “I don't blame you for being puz zled,” T cheered him a bit. “There is probably no part of radio theory that is more carelessly explained than the change from radio to audio. I think | you have got it pretty well fixed in your mind that the original sound variations or values are carried on electro-magnetic waves oscillating anywhere from 50,000 to 1,000,000 cyeles per second, and you recognize this as alte ting current. but from the talk you hear it is certainly difi- cult to know whether the current is ternating direct after the de- tector tube has rectified it Smith Has Same Problem. That's just my problem,” he ad- mitted. “I can visualize the radio frequency—those high speed oscilla- tions—reaching the grid of the de- tector tube. I can see the negative electrons being attrabted across the gap to the plate of the tube which is positively charged with the current from the “B" battery. I can clearly understand that this arrangement means that the current from the plate to the earphones can go only in one direction because it has been recti- fied by the tube. But then why do they talk about this rectified current as ‘audio frequency'? 1 thought ‘fre. quency’ was the term used to define the number of cycles of any oscillation And after the current is converted into the audio type it's supposed to go in just one direction Here he pointed to contradictory statements which he had picked from various sources, which certainly lef doubt as to just what did happen after the detector got through with the radio frequency form of the current. “I've been puzzled over just the same point,” 1 told Smith, “but I've finally got it straight from practical electricians. It is a pretty and I guess there is much to be taken for granted, but it ease you considerably to know that the current is no longer alternating after it has passed through the detector, whether you use a crystal for this purpose or a detector tube.’ “Fine!” Smith exclaimed. *But then why speak of audio frequency when the current in audio form is not alter. nating? How can there be oscillations in direct current?” Term Found Confusing. “That's just where they confuse us.” 1 explained. “You see. all electrical circuits are oscillations. It is the basis upon which radio stands. But the term is rather vaguely used First they are using it to mean alter nations, then to mean pulsation This is confusing, and unnecessary. “Just picture the current coming in over the antenna as alternating cur rent. Picture its changing its direc- titon thousands of times a second. And regard it as a series of electrical oscillatians. Now you have the term ‘oscillations’ jn its most logical sense and you can figure that, used in other connections, it is often somewhat loose- ly employed. I will give you an in- stance: ““On these oscillations of the current being sent out by the broadcasting station are impressed the audio fre- quencies or sound wave variations. After this current is picked up, am- plified and changed by the detector tube to direct current the original osclllations disappear and the only characteristics that remain to influ- ence the direct current are the original sound waves. This causes the direct current to puleate. Instead of being constant it is really intermittent be. cause it is being controlled by the Now he has takenm up radio, tions are often loosely referred to as oscillations. “An electriclan I talked with sug- gested a simple way io think of this tricky part of radio. He says to con- sider radio frequency as referring to the number of cyclas per second of the oscillations received by the set and to consider audic frequency as the number of cycles per second of pulsa- tions which correspond to the sound waves and which, with the aid of the earphones, are audible to the ear. He said that in the changeover from radio to audio the alternating current merely loses one ‘leg.” 1,thought that about sized it up.” “After l0sing a leg it can't move so swiftly, I suppose,” Smith added, “and we then get a chance to catch the sounds and learn what's going on over the air.” A|Next Week, No. 19—Nothing on the e (Copyright, 1925, by the Ullman Features Service.)
