CINCINNATIAN REFUTES KDKA 'PIONEER' CLAIMS
Declares Old Precision Equipment Company Broadcast First After Naval "Stunt."
Recent celebration of its sixth birthday by station KDKA, at Pittsburgh, has caused considerable discussion as to the birth of radio broadcasting together with the questioning of KDKA's claim of being the first broadcaster on the air.
According to Lieutenant F. H. Breckel of the Precision Equipment company of Cincinnati, his organization built and operated a 10-watt station under the call letters 8XB several months prior to the commencement of broadcasting at Pittsburgh. Even before this time in 1919, the Cincinnati station transmitted under the call letters PC, test programs that included phonograph records and voice accompaniments.
The first music that was ever broadcast, according to Lieutenant Breckel, was "On the 5:15," a popular song of eight or nine years ago. This one record was played over and over hundreds of times and reception of the music was reported by amateur wireless operators several hundred miles from Cincinnati.
Although claiming the honor of being the first broadcasting in the United States for the Precision company, Lieutenant Breckel points out that a broadcasting stunt prior to those carried on in Cincinnati was performed in 1918 during the world war, when the U. S. S. George Washington, lying in the harbor of Brest, transmitted phonograph music through its wireless for the entertainment of the patrol and anti-submarine forces nearby.
