L107 replaced '107 The Edge', which was originally launched as 'Clan FM' from 1999 until 2003, when it was saved from closure by the Kingdom
Radio Group and rebranded. Within two years, the station was again saved from closure by former Radio 1 and Radio Clyde presenter Mark Page (founder of the UK forces station Garrison Radio), who led its relaunch as L107, a full service local station.
The station closed at 10am on 18 August 2008 but reopened at 9am on 26 August 2008 following a buyout and continued broadcasting for another year. The station went off air for almost a week on 30 April 2010 when its main transmitter was removed from its Hamilton site.
