DevonAir was initially successful, but financial problems resulted in a takeover by Capital Radio in 1987.

In October 1993 the station lost its franchise and closed on 31 December 1994, leading to the creation of Gemini FM.

In September 2008, it was announced that Gemini FM was to become Heart as part of a national rebranding exercise by new owners Global Radio.
