In 1987, Canberra radio station 2CA was awarded the licence to operate a supplementary FM service. The station was assigned the call-sign 2ROC and on-air branding FM104 (later changed to FM104.7). It commenced broadcasting on 27 February 1988 on the frequency 104.7 MHzFM. FM104, along with rival KIX106, were the first new commercial FM radio stations to be licenced in Australia in eight years and were the first supplementary FM licences in Australia.
In the mid-1990s, due to AM radio's dwindling audience and the increasing popularity of the music based FM stations Austereo - owner of 104.7 & 2CA and ARN - owner of Mix 106.3 & 2CC, merged to form a joint venture ownership of both FM stations - Canberra FM Pty Ltd. The AM stations were sold off and moved to other premises.
