THE ROMANCE OF THE RADIO TELEPHONE [NOF extract]
BY C. AUSTIN
Probably it is not generally known that the United States Navy is a pioneer of broadcasting, but Navy records and the memories of early radio enthusiasts prove that the Anacostia Naval Air Station near Washington broadcasted music by radio phone for the first time on January 17, 1920. The Navy had, of course, been broadcasting by code for some years previously, but this was the occasion of the first radio telephone entertainment. Commander A. Hoyt Taylor was then in charge of the Anacostia station, then the highest powered radio station in the country with a range of 1,000 miles. A phonograph concert was transmitted weekly, followed by technical information for amateurs, for a considerable period. Navy records show that communications were received in February and again in March, 1920, from St. Louis, Minneapolis, and places in Pennsylvania congratulating the Anacostia station on the strength of its signals.
