In November 2005, it was announced that GCap's local radio stations in the South West, including Plymouth Sound, were to be sold as they were outside of the company's primary target area.

[1] Four months later GCap decided that the sale would not go ahead, essentially because the offers made fell short of their expectations.

[2] In September 2008, it was announced that Plymouth Sound would be rebranded Heart FM as part of a national rebranding exercise by owners Global Radio, which saw twenty-nine stations renamed as Heart.

[3] The new station, Heart Devon, began broadcasting from Exeter on 27 August 2010.

[4] The Christian media group and radio station Cross Rhythms grew out of a half-hour Christian music show on Plymouth Sound FM, which aired on Sunday evenings between 1983 and 1996.
