Radio Digest (July 1924-Apr 1925)

RADIO DIGES T— Illustrated February 14, 1925 HIS VOICE TO REACH ALL OVER COUNTRY President Coolidg-e will toe the first president of the United States ever to have had his inaugural ceremonies broadcast. On March 4 over thirty stations located from coast to coast, a record-breaking chain of broadcasters, will give the inauguration program simultaneously direct from Washington. The above photo was taken when he broadcast a speech some time ago at a banquet in New Yorfc. BROADCAST INAUGURAL (Continued from page 1) wire lines transmit the program "to WJZ, its New York station, and WGY, the Schenectady station of the General Electric company, for broadcasting at those points. Probable Stations to Broadcast The usual A. T. & T. link, consisting of Stations WCAP, WJAR, WEEI, WDBH, WGR, WCAE and WPI, will undoubtedly carry the inaugural program. Many other stations will be tied in besides. The "Westinghouse group of WBZ, KDKA, KYW and KFKX are almost certain to be included. KOA and KGO, Denver and Oakland stations respectively of the General Electric company, are also fairly sure to be in the link. More than sixteen other 500-watt broadcasters located in every part of the country are negotiating for the privilege of sharing a part of the expense and carrying the ceremonies on March 4. The final list of participating stations will be announced just prior to the event. To the Radiophan of today the fact that a public address loud speaker system is to be installed means but little. Four years ago, however, it marked an epoch-making event in the history of voice transmission. Newspapers throughout the country on the evening of March 4, 1920, and the following day carried the headlines, "125,000 People Hear Harding's Voice," "A Telephone Achievement Ranking with the Opening of the Transcontinental Line," and then proceeded to tell the story of how, "with the aid of the Bell loud speaker, installed at "Washington by engineers of the Bell system, President Harding addressed the greatest number of people that has ever listened to one man's voice at one time in the history of the world." People throughout the land were amazed when they learned that on this inauguration day the voice of President Harding was clearly heard and understood by a crowd of 125,000 people, a crowd that completely filled the plaza in front of the capitol and overflowed into the park beyond. Today this same equipment acts as an aid to bring the voice of the President of the United States not to 125,000 but to several millions. It is this equipment, combined with the use of the long distance telephone lines of the Bell system and Radio relays, that brings the human voice to many stations for broadcasting. THEATRICAL LIGHTS GIVE RADIO ALARM WHILE MOVIE MANAGERS INDORSE BROADCASTS Actors' Equity Organizes Committee to Discuss Radiocast Competition and Other Problems NEW YORK. — Representatives of actors, managers, dramatists, composers, scenic artists, publishers, stage hands and musicians — leading lights of the theatrical world — sounded a Radio alarm recently when they met together here for the first time in history to form a committee to make plans for the "betterment of the institution to which we all belong." Radio broadcasting and its relation to the theater, discussed pro and con, mostly con, for two hours was named as the first matter for the committee to handle. The Actors' Equity association is the moving spirit behind the organization of the new committee of the theater. Although many other problems are said to be ready for discussio/i by the proposed committee, none of these has been named. Radio's so-called competition with the spoken play is of chief interest. Movie Managers Indorse Radio While the Actors' Equity in New York was sponsoring the call to arms against Radio, down in Atlanta, Georgia, the Famous Players-Lasky theater managers from all parts of the United States and Canada in convention assembled unanimously indorsed Radio broadcasting as an influence beneficial to the growth and prosperity of the silent drama. The motion picture theater managers further declared themselves in favor of a policy of close co-operation between theater directors and broadcasting stations. The meeting was attended by Jesse L. Lasky, production manager of the organization, and Harold B. Franklin, head of the theater department. Lambdin Kay, director of WSB, the Atlanta Journal station, spoke in behalf of broadcasting. FADING RECORDER IS AID TO ECLIPSE TEST The apparatus pictured is a fading recorder and was used by the Radio Corporation of America in the recent Radio eclipse tests in New York city to make a permanent record of the effect the eclipse had on Radio signals of various wave lengths. If signals came in always with the same strength the result would be a straight line on the paper tape. Note the wavy line on the tape.
