The station, serving a population of around 150,000, broadcast programmes from its studios in the town during daytime (6am - 6pm) but shared output from its larger sister SGR station in Ipswich at other times.

The Colchester station was an immediate success and quickly built an impressive audience locally, soon establishing itself as market leader.

Staff in the early years included Mike Stewart (group programme director), Danny Cox (station manager) and presenters Nick Jackson and Simon Taylor.

In January 2009, owners Global Radio re-branded SGR Colchester as Heart Colchester and the following year, it was merged with Heart Essex, resulting in the closure of the station's studio base in the town.
