4RGK
4RGK is a radio station in Central Queensland, currently broadcasting as Triple M.
The station adopted the Triple M branding in December 2016 as part of Southern Cross Austereo's branding overhaul of its regional radio networks. Prior to this, the station had been known as Sea FM.
4RGK began test broadcasts in Rockhampton and Gladstone in September 2000, and officially launched as Sea FM in October 2000, broadcasting to the Rockhampton area on 101.5 FM and the Gladstone area on 95.1 FM.
When the station was launched, it was owned by RG Capital Radio, which already owned the existing Rockhampton AM station 4RO.
A rival radio company, DMG Regional Radio, also launched their FM station in Rockhampton at the same time, with Hot FM beginning transmission in Central Queensland. RG Capital Radio and DMG Regional Radio both successfully bid for the FM licenses in 1998, eventually leading to the simultaneous launch of the two competing stations in 2000.
Unlike Sea FM, which began broadcasting a 'live and local' format from their Rockhampton studio between 5am and 6pm, Hot FM heavily relied on networking their daytime programming from their hub in Townsville. In 2005, RG Capital Radio and DMG Regional Radio merged to become Macquarie Radioworks, and the two rival stations became stablemates. The merger also meant that the two AM stations 4RO and 4CC were also owned by the same company, and as a result had to be offloaded and were later sold to Prime Media Group.
Since the original merger, a number of other mergers have occurred which has affected Sea FM's formatting. Macquarie and Southern Cross Broadcasting merged to become Macquarie Southern Cross Media, then Macquarie Southern Cross merged with Austereo to become Southern Cross Austereo.
Since Sea FM became part of Southern Cross Austereo, the station is now considered to be part of the Triple M Local Works stream to be aligned with the network's metropolitan Triple M stations, and is due to change its name from Sea FM to Triple M in December 2016.
