W2XCR
Encyclopedia
W2XCR was founded in 1931 in Long Island City, NY by the radio station WGBS (now WINS-AM). During the period early part of 1931, but before the call letters were changed to WINS, the station began experimenting with mechanical television broadcasting, operating a Jenkins mechanical scanner through the experimental transmitter, W2XCR. The station broadcast using both 48-line, 15 frame/s, and 60-line, 20 frame/s standards during 1931.
Mechanical TV broadcast in the AM radio band (550-1600 kHz) in 1928 and 1929. With 24 and 30 line systems, only about 10 kHz of bandwidth was needed, so standard radio channels could be used. Some stations also broadcast in the shortwave band. Beginning in 1930, the 2-3 mHz band was used for television, with 100 kHz channel width. 60 line systems required about 40 kHz of bandwidth. TV broadcasts could be identified by their distinctive sound.
