Reception can be obtained from local stations and from stations located at considerable distance with a small in-door wire aerial.

THE INDIANAPOLIS TIMES

AIR CONGESTION NOW PROBLEM FOR ENGINEERS Wave Lengths Being Sought for Stations Asking Licenses. Bu XK.I Service WASHINGTON, Sett. 24.—With more than 680 broadcasting stations now in operation, radio engineers are seeking wave lengths for new stations which are constantly applying for licenses. Congestion problems could be solved if it were possible to keep the aerial traffic jams out of the cities. Tabulation Made A recent tabulation of all stations by the Radio Bureau shows that out of forty-seven stations in Illinois, seventeen are in Chicago. New York City and immediate vicinity has most of New York State's thirty-four. California, with forty-eight, leads all States in the number of stations. Eight of these are in Los Angeles, seven in San Francisco, five in Oakland, and three in Hollywood. Curing the summer the Bureau of Standards has conducted tests of socalled superpower stations. Results showed that highpower did not result in signals of such overwhelming intensity as to drown out smaller stations. Reception Fluctuates The investigations also disclosed that reception from stations broadcatsing with ordinary power, more than fifty miles away, is continually fluctuating. While engineers are experimenting, the public is increasing its use of radio. The Department of Agriculture estimates that more than 550,000 American farms are equipped with radio receiving sets. FRENCH CHIEFS GKT SET President Doumergue of France if.- one of the country's leading radio fans. He has had anew receiving set installed,, in the summer residence of the French chiefs of state.
