2MT
2MT was the first British radio station to make regular entertainment broadcasts, and the world's first regular wireless broadcast for entertainment. Transmissions began on 14 February 1922 from an ex-Army hut next to the Marconi laboratories at Writtle, near Chelmsford in Essex. Initially the station only had 200 watts and transmitted on 700m (428 kHz) on Tuesdays from 2000 to 2030.
