(Part of Series) Mobile Teletype

San Pedro, California--The army signal corps demonstrated a mobile radio-teletype so new it was never used in battle from San Pedro Hill near here, transmitting to and receiving messages from a similar mobile unit at Coles Signal Lab near Red Bank, N.J. These mobile units, the first to be built and tested by the army, provide a single 60 word per minute teletype channel with a range of 2,000 miles. Similar sets have already been installed in President Truman's plane and train. All needed equipment can be carried by four 2 1/2 ton trucks. The three "shelters" with operating, transmitting and receiving stations, power units and antennae can be put into operation in about four hours or dismantled in two. Fifteen men, plus teletype operators, staff a unit. This equipment could be used in ship to shore communication. In amphibious operations, once a set is landed, communication can be made within four hours to similar units as far away as 2,000 miles.
