4GR is an Australian commercial radio station located in Toowoomba, Queensland, currently broadcasting as Triple M on 864 AM.[1]
The station was the first commercial radio station to broadcast in Queensland.
4GR was the brainchild of Edward Gold[2] who had conducted test radio broadcasts in a shed from his experimental radio station 4EG prior to obtaining Queensland's first commercial radio licence to establish 4GR, which began broadcasting on 17 August 1925.[3]
Transmitter power is 2 KW.
In 2015, 4GR celebrated its 90th birthday.[4]
Despite the station identifying itself as its original callsign 4GR for more than 90 years, the on-air branding was changed to Triple M in December 2016 as part of Southern Cross Austereo's branding overhaul of its regional radio networks.[5]
4GR's name change came under fire from some quarters. An online reader's poll run by The Chronicle newspaper in Toowoomba found that 74% of respondents were unhappy with 4GR taking on the Triple M brand.[6]
