Heart Gloucestershire (formerly Severn Sound) was an Independent Local Radio station owned and operated by Global Radio as part of the Heart network. It broadcast to Gloucestershire from studios in Gloucester.

The transmitter is at Churchdown Hill, just west of the M5; the same transmitter as Radio Gloucestershire.

Severn Sound started transmissions on 23 October 1980, from its first studio at the "Old Talbot Pub" in Southgate Street, Gloucester. The pub had been bought by local businessmen including Clive Lindley (Chairman of the Roadchef motorway service stations and Chairman of Severn Sound).The station's first employee was Chief Engineer Quentin Howard, who converted the pub into the radio station.

The original presenters were Alan Roberts (Head of Music) on Breakfast, Christopher Musk on mid-mornings, Eddie Vickers (Programme Controller) on the Lunchtime News and Topical programme, Laura de Vere on the Afternoon Show and Steve Ellis on Drivetime. There used to be a Sunday lunchtime show where the presenter would go to various areas of Gloucester and share Sunday lunch with the residents of that house.

One notable director was the writer Dennis Potter, who played an active role in the station's early years and lived in Ross on Wye. Potter's Pennies from Heaven producer, Kenith Trodd, presented a Sunday programme of 78 records featuring singers such as Al Bowlly, which Todd and Potter had used in Pennies from Heaven. Another Director was England rugby player, Mike Burton, who also started Gulliver's Travels, a sports travel agency.

On 1 July 1984 two of the station's engineers, Nigel Lane and Tony Cooper, were killed on an outside broadcast.^[1][2] The telescopic mast of their radio car touched an overhead 11 kV power line, whilst they were preparing for a live broadcast from Sudeley Castle, Winchcombe. The inquiry into the accident found Severn Sound guilty of health and safety offences and fined the company £2,500. Many new safety procedures for radio cars were introduced across the whole industry as a result of the accident.

The station was sold to the Chiltern Radio Group, after some resistance, in 1989 and was later taken over by the GWR Group in 1995. GCap Media was sold to Global Radio in 2008.

During the Gloucester/Tewkesbury flood crisis of Summer 2007, Severn Sound was forced to move, temporarily, to the GWR FM Bristol Studios, due to a loss of electricity and running water.^[3]
