Spin 103.8 is owned by Denis O'Brien's Communicorp group and broadcasts under a sound broadcasting contract with the Broadcasting Commission of Ireland.
Despite their name, they do not broadcast on the medium wave band (1038 not being a valid mediumwave frequency, anyway), but on 103.8 FM.
Spin 1038 is mostly heard in Dublin but can also be heard in towns such as Naas, Celbridge, Leixlip, Maynooth, Drogheda and Bray due to their close proximity to Dublin.
The station (which originally applied for its contract as "Spin FM") was one of three new ILR stations which were awarded franchises in October 1999. It was intended to provide an alternative for listeners younger than those catered for by the original two Dublin ILR stations, FM104 and Dublin's 98FM. The station however was subject to delays due to legal action from an unsuccessful opposing consortium, however finally took the air as Spin 1038 at 10:38am on 19 April 2002.
Despite being initially known as "the dance licence", the station now plays mainly popular music.
