Radio Mercury began airing on 20 October 1984, on 103.6 FM and 1521 AM focusing on Crawley but serving much of East Surrey and North Sussex. Two years later, the FM frequency changed to 102.7 as part of the UK-wide re-organisation of the VHF/FM band. 1989 saw a relay of the station added for the town of Horsham on 97.5. In 1991 the station took over most of County Sound Radio in Guildford to form the Allied Radio plc.
Mercury then, having played a broad mix of music, became a mainly Top 40 hits station. County Sound's AM frequency was later renamed "Extra AM" and then again was shortly renamed to "Mercury Extra AM" to make the connection between the two AM frequencies of both stations better known. It also became known as The Breeze, until the Classic Gold Network took over the AM licence of 1521 kHz. On 102.7 FM Mercury was renamed "Mercury FM" after the takeover of the group by GWR, later GCap Media. Before that Mercury lost the County Sound region again, and Eagle Radio took the Surrey 96.4 FM transmitter, and County Sound returned to 1476 AM.
The station was incorporated into GCap's "One Network" of stations, until the merger between GCap and Chrysalis Radio, forming Global Radio. As part of this merger, many of the former One Network stations were rebranded and reformatted under the "Heart" network which still stands today.
