It broadcasts on FM, DAB, digital TV and via BBC Sounds from studios on Queens Road in Brighton.
The transmission area was initially restricted to little more than the immediate Brighton and Hove conurbation, with the surrounding suburbs.
On 22 October 1983, as part of the BBC's move to extend its local radio network across the UK, the station expanded further to include the entire county.
However, in September 1997, two dedicated breakfast shows were introduced, one for Brighton and Hove on the 95.3 FM frequency and another for the remainder of Sussex.
Listeners in Crawley and parts of East Grinstead cannot receive FM signals that broadcast BBC Radio Sussex.
BBC Radio Sussex covers every Brighton and Hove Albion and Crawley Town game live.
On Saturdays, BBC Sussex Sport starts at 2pm, presented by Johnny Cantor[citation needed] from wherever Brighton are playing.
