Don FM is an influential London pirate radio station, which along with a handful of other stations, was critical in the development of Breakbeat hardcore, Oldschool jungle and Drum and Bass music. It first broadcast in November 1992 on the frequency of 105.7FM from South London. On the 28th March 1994, it ceased broadcasting to apply for a temporary Restricted Service License. It won this and broadcast legally for 4 weeks from 28th August 1994 on 100.5FM to London, and remains the only pirate radio station of its genre to have done so. Don FM returned between 1995 and 1997 on the frequency of 107.9FM.

Don FM has produced a number of today's highly respected Jungle, Drum and Bass and Garage DJs, MC's and artists, such as DJ Trace, Ed Rush, Deekline, Hyperactiv, G-Force, and Stevie A.
