Oakland Tribune, February 2, 1922, page 7:
SCRAMBLED JAZZ IS BANISHED BY NEW AIR RULES
To prevent the atmosphere from being "cluttered up" with wireless music, news bulletins, speeches and sermons, which are often broadcasted by amateur wireless telephone operators not licensed as radio commercial stations, orders have been received by Radio Inspector J. F. Dillon of the bureau of navigation from Washington preventing broadcasting by these non-licensed stations.
The order is the outgrowth of what was known as the Pacific Plan for regulating amateur radio traffic adopted at a conference representative of 25 radio clubs which met in San Francisco in December.
From today on only radio stations specially licensed, like commercial establishments, may broadcast news, music and the like. The new order will eliminate the duplication of such stunts as the playing of jazz music during a church sermon, as occurred at the recent demonstration of The TRIBUNE'S wireless, when the sermon of Rev. R. A. Van Winkle was interrupted for a few moments by the playing of jazz music.
The TRIBUNE'S wireless telephone, operated by P. D. Allen, wireless expert, who conducts a wireless school at the Hotel Oakland, is a licensed commercial establishment. News bulletins are broadcasted every evening at 7:15 o'clock.
