Crown FM began broadcasting trials on 3 July 1999 using a restricted service licence on 107.3 MHz FM via a mast at Mousehold Heath.
Further RSLs took place in the 28 days leading up to Christmas in 1999, 2000 and 2001, and from 26 April to 23 May 2003.
The British communications regulator, Ofcom, advertised a permanent licence for the area on 8 December 2004. On the closing date of 9 March 2005, Crown FM was one of five bidders, with Lite FM Norwich (from Forward Media), Norwich 99.9 FM (from Wireless Group), NRG fm (from local interests, including Archant Regional) and Today FM (from UKRD Group).
Ofcom announced 13 weeks later that Crown FM had won the licence for 12 years.
The station opened on 29 June 2006 under the name 99.9 Radio Norwich with the slogan The New Number For Norwich.
