Following the successful application to run a new station in Leicester which it launched as Leicester Sound, Radio Trent expanded transmission to neighbouring Derbyshire in 1987. Renamed Trent FM in 1988, it launched a separate oldies-format service, GEM-AM, on its own medium wave frequencies alongside that of Leicester Sound. Its owners Midlands Radio plc were taken over by the Capital Radio group GWR Group in 1993, which then disposed of the East Midlands assets to GWR. The Nottingham and Mansfield FM services were branded 96 Trent FM, while the Derby service became known as RAM FM. The medium wave GEM-AM service was then rebranded, to become Classic Gold GEM, and ultimately Classic Gold.
