- TELEVISION METHOD DIVIDES ENGINEERS One School Favors Wired Ra- .dio, Another Holds Broad- casting Best Medium. ‘Two schools of engincering thought | have developed with respect to tele- | vis.on. One hofds that television’s best | chances lie with wired radio—that is, along the carrier frequency Klths of telephone or power lines. The other regards space radio as the more feasible transmission medium for television signals. Wired radio is making progress an its introduction as an additional audi- 1s only a short dis- A ired radio interests are not overlooking television in their de- velopmental work. They are lookha e day when they can offer visu: :lonl with audible entertainment fea- ures. Space radio, better known as broad- casting, is, of course, firmly established. Many experimenters in television are working toward the end that the ether channels shall carry signals to be trans- lated into moving images at the receiver —in fact, the space radio television workers have been much more articulate than these working with wired radio, although it is a fact that most experi- ments with television are usually first | conducted with wires. Institute Head for Wired Radio. J. E. Smith, president of the National Radio Institute of Washington, is one of those who believe that wired radio will remove many of the perplexing ;mblem! that must be solved in per- ecting television. “Who knows,” says Mr. Smith, “but that the invention of wired radio may bring about the same advancement in Jm development of television that the vacuum tube brought to the ex- nsion of transmission and reception the early stages of radio? “There would be no necessity,” he continues, “for considering the width of the wave band, or, as it is sometimes called, the 10-kilocycle channel allotted the Federal Radio Commission for the television transmission, because by wired radio television signals would be Testrictea to the metallic conductor acting as carrier. The engineering prob- lem of finding methods to eliminate blurs on the receiver picture, caused by the atmospheric disturbances known as static and fading, would be over- come.” Synchronizing the receiver with the transmitter would be simpler along wires, according to Mr. Smith. The ‘wave length factor would be eliminated, for the television by space radio re- a band of channels ten times t required for audible broadcasting. already crowded and no leral mfinl hannels, t v; channels, except as exgenmen the hours after midnight. Radio Engineers Differ. All radio engineers are not in agree- ment on the practicability of trans- mitting either - audible or television by wired radio. The indus- doubt is plainly prompted by fear of a disturbed market for radio re- selving sets. It is also the belief in some circles that the public, accustomed %o obtaiming its space radio programs free of direct cost, will not be willing to pay for wired radio service of a line , even the wired pro- contain no X Refusing to be qyoted ly Because their affiliations, several ‘eminent in the radio ve admitted to the writer that wires as the logical medium of levision when TO CHICAGO LIBERTY LIMITED Lv.

LOUIS First Heavy Frost Of Year Recorded By Bureau Today With the mercury hovering at 35 degrees yesterday morning, Wash-, ington " and the surrounding country was bathed in the first general heavy frost of the year, according to the Weather Bu- reau’s announcement yesterday. ht frosts had been recorded in ti suburban areas prior to Tuesday night, the Weather Bu- reau explained, but the condition which was caused early today was the first severe killing frost of the year. ‘The forecasters are of the opin- jon, however, that if there is any frost at all tonight it will be con- siderably lighter, for they believe it will be much warmer after to- day. While Washingtonians were concerned with the effects of the frost on their flowers, aviators were thinking about clothing. Red flannel underyear may be out of date, but it would have been welcome to pilots on the New York-Richmond airmail run last night. “Dick” Merrill, north- bound, and Lawrence Pabst, southbound, reported plenty of cold all the way. Merrill, how- ever, has more than the cold to worry about. His mascot, a tiny flying squirrel, which has accom- panied him on the night mail for weeks, is absent without leave. SWANSON PREDICTS RETURN OF SOUTH Holds Virginia Election Indicates Normal Political Condition Is Democratic. Senator Swanson, Democrat, of Vir- ginia, commenting yesterday on the re- syt of the Virginia elections Tuesday, persisted that the South will return to the Democratic party. Senator Swan- son issued the following statement: “The result of the election just held in Virginia very clearly indicates that under normal political conditiéns and issues Virginia is overwhelmingly Demo- cratic. ‘The result in this election in- sures that in the election to be held next year Virginia will by a very large majority elect a Democratic Senator and Democratic Representatives from every congressional district in the State. ‘The majority in the State and in every congressional district next year will ex- ceed the majority given in this election. “The result of this election means that in the future there will be but two parties in Virginia, Democratic and Re- publican. “This election also indicates that the will return to the Demo- A irrespective of the differences o by television is perfected. They based their conclusions on the belief that the tech- nical difficulties are easier to overcome and that some one will have to pay the cost of television. On the other hand, Dr. Alfred N. Goldsmith, the Radio Corporation of America engineer, says that wired radio has technical difficulties of its own that are even more serious than the prob- lems of space radio. Dr. Goldsmith foresees a distinct problem in getting people to pay for television services. He says he confidently believes that ad- The cont of mual programe, Just s tacy cost of al , just as now for the immediate costs of audibl casting. by North American News- per_Allianc THE EVENING STAR, WASHINGTON, STRIDES IN RADIO MADE IN 9 YEARS = Station KDKA Broadcast the First Election Returns November 2, 1920. Popular broadcasting started exactly nine years ago today. November 2, 1920, the first scheduled radio program went on the air trom Station KDKA, Pitts- burgh. The program consisted of the election returns which carried Warren G. Harding into office. Program radio has passed through many viscissitudes sinte that time, and the end is not yet in sight. The broad- casting spectrum, with its scarcity of wave lengths, is congested with a multi- plicity of stations. The Federal Radio Commission, created only after radio had passed its sixth birthday anniver- sary, is still casting about for ways and means of bringing order and equity into the broadcasting realm. ‘This anniversary of radio, from the point of view of the American listener, who has invested well over $3,000,000,000 in radio receiving equipment in the last nine years, is notable most for radio’s remarkable achievements in the face of technical and political odds. Conditions Are Changed. As bad as reception conditions are in some parts of the country, there is scarcely any spot where the choice of two or three programs at any hour of the day is unavailable. Nine years ago, when crystal receiving sets were owned by a mere handful of persons, this would have been regarded as an ideal condition. Station KDKA was not the first to broadcast speech and music after new- ly developed wrinkles in the art of radio-telegraphy had made it possible to utilize somewhat broader radio chan- nels for radio-telephony. Dr. Lee De Forest, justly called the father of mod- ern radio, because of his invention of the vacuum tubes, operated an experi- mental broadcasting station in the Metropolitan Opera House some years earlier. Station KDKA, however, was the first to broadcast a program for reception by a relatively large audience. | The success of the KDKA broadcast, the technical supervision of which was in the hands of Dr. Fran Conrad, West- inghouse engineer, lent impetus to fur- ther broadcasting activity. Station KDKA, then regarded as a part-time experimenter in “radio-telephony,” did not, in fact, secure its Federal broad- casting license until November of the following year. Meanwhile the first license was issued to WBZ, Springfield, FOUND A way to beat Old Man Depre- ciation; just see what you save on a, 1930 Dodge automobile.

In the meantime the Westinghouse company stressed the market for crystal receivers, many of which are still in use today. So that many persons would buy these receivers, more stations took to the air. The single wave length of 360 meters was reserved by the Govern- ment for broadcasting, still regarded as merely a curiosity. The beginning of 1922 found 36 stations in operation. The same year ended with nearly 600 on the air. There are still more than 600 sta- tions in existence in this country. The‘ largest number ever on the air was 733. Many fell by the wayside as the indu: try looked for means of sustaining i self financially. Early programs ma‘ no advertising. Broadcasting was first regarded merely as a necessary adjunct to an industry seeking a market for its wares. The market could only be found by creating more listeners. , ‘The rest of the story of broadcasting’s growth and development, particularly after the sets using Dr. Forest's vacuum tube began to be marketed, has often been told.

Aftr 1924 the public generally has preferred to buy cw:lnpleu sets—rather than parts for re- pairs. (Copyright, 1929. by North American News- Daper Alliance.) Clmand e Students Renew Attacks on Jews.
