The station started broadcasting on 1548 kHz/194m AM, 95.2 and 95.9 MHz FM under the name of Radio Hallam from its studios at Hartshead in Sheffield City Centre on 1 October 1974. The first presenter heard on air was ex-BBC Radio 1 DJ Johnny Moran - the first record he played was I've Got the Music in Me by Kiki Dee, which stuck after a minute and a half. On 1 October 1985, Radio Hallam's broadcast area significantly increased when it began to broadcast to all of South Yorkshire. In 1987, Radio Hallam merged with neighbouring Yorkshire stations Pennine Radio in Bradford and Viking Radio in Hull to form the now-defunct Yorkshire Radio Network. The frequencies were changed during the 1980s to 96.1 FM for Rotherham, 97.4 FM for Sheffield, 102.9 FM for Barnsley, and 103.4 for the remainder of South Yorkshire. After a take-over of the parent company YRN by the Metro Radio Group, the AM frequency became Great Yorkshire Gold. As part of Hallam's licence agreement, the Rotherham transmitter ceased to be used by the station in the 1990s and is now used by Rother FM. Hallam also moved its studio facilities to 900 Herries Road, just minutes from Sheffield Wednesday's Hillsborough ground. The office space at Hartshead was formerly used by the Sheffield Star newspaper. As the Metro Radio group was bought by EMAP, Hallam FM also became part of the Big City Network in Northern England. In 2011, Bauer Media's Big City Network was replaced by the Place Portfolio, containing the group's local radio stations. As of October 2019, Hallam FM's Sheffield studios are shared with sister Yorkshire station Viking FM, following the closure of Viking's studios in Hull.
