Wireless Experiments in Cleveland
In order to demonstrate the practicability of radio communication in the fire department, First Assistant Chief James E. Granger made several practical tests recently which convinced him as to its importance which cannot be overlooked. A portable station was set up in the chief’s office, which was compact in an ordinary suit case. The official United States weather renorts were received, also signals from various Great Lakes radio stations, including the So. Detroit, Buffalo, Cleveland, and the Glenn Martin Air Field. These signals were all very distinct and could be heard in any part of the room with the receivers lying on the table. After these demonstrations, Chief Granger took his car with the equipment and drove to a different part of the city, and after stopping within five minutes a temporary station was in full operation. Chief Granger heard, while standing beside his car in the street, Detroit and Buffalo talking, also Detroit talking to a D. & C. vessel, also a freighter on Lake Superior. The set consisted of a regenerative receiver with one step amplification. The battery for the starter on the chief’s car was used for the primary or “a” battery.
