Radio Invicta is a free radio station that broadcast in London from 1970 to 1984. Most of the time, Radio Invicta operated in VHF on 92.4 MHz. It used the slogans "Soul over London" and "Europe''s first and only all soul station". Radio Invicta was the first UK station to play only soul music, so it had a major influence on soul and dance music in the UK. Radio broadcasting is an audio (sound) broadcasting service, broadcast through the air as radio waves (a form of electromagnetic radiation) from a transmitter to a receiving antenna. Stations can be linked in radio networks to broadcast common programming, either in syndication or simulcast or both. Audio broadcasting also can be done via cable FM, local wire networks, satellite and the Internet.
