Wireless Concerts Said Coming in Near Future
_______
CINCINNATI, O., Thursday, Feb. 5.--"Wireless concerts" in which a properly equipped audience in San Francisco can sit and listen to the playing of a symphony in New York will be an innovation of the near future, in the belief of John L. Gates, wireless telephone expert.
He bases his belief on the results of an experiment here in which wireless telephone operators within a radius of ten miles "listened in" on a phonograph record concert he gave. He reported they heard the music distinctly.
