The station was fully launched on 20 September 1992 (the licence ran from the 5th, when test transmissions began to include programmes about the Salisbury Arts Festival). Spire FM broadcast from City Hall Studios in Malthouse Lane, Salisbury, part of the City Hall entertainment venue. Originally independently owned, it was acquired by Radio Investments Limited in 1995, and from 1996 the station was owned by
The Local Radio Company, which was a joint venture with
GWR Group until it was converted into an AIM-quoted company in 2004. TLRC was acquired by
UKRD Group in 2009, and
Bauer Radio bought UKRD's ten stations in 2019. Spire FM won a prestigious
Sony Radio Award for Station of the Year in 1994 and the runner-up award in 2003. Other awards included the KPMG Marketing Excellence Award, and Wiltshire Business of the Year finalists.
Bauer Media rebranded the station as Greatest Hits Radio Salisbury in September 2020, as part of their national
Greatest Hits Radio network. It now broadcasts national and regional music programmes with local news bulletins. In January 2024, Bauer dropped local news bulletins for Salisbury - determining these to sound "jarring and parochial" alongside networked programming - and instead transmitted bulletins shared with the (then digital-only, prior to the April flip of
Wave 105) South Hampshire iteration of GHR. Salisbury-specific bulletins on weekdays were reinstated in March 2024.
Ofcom considered that a complaint about the lack of local news material had been resolved by their reintroduction. ==Programming==
