Tuesday 8 October 2013 sees the 40th anniversary of the UK's first independent radio broadcaster the London Broadcasting Company (LBC) on 97.3 MHz FM and 1152 kHz AM
Prior to then the only licensed radio broadcaster in the UK was the state controlled BBC (the UK Government controlled the level of the BBC's income and had the right of veto on senior management appointments).
Although LBC's coverage area was London and Home Counties the AM signal on 1152 kHz could be received far wider. On 13 November 1985 Gary Deacon received LBC in Cape Town, South Africa.
