History

The 5CK transmitter station, located around 5 km from Crystal Brook on the Gladstone road, was officially opened on 15 March 1932 as a relay of 5CL Adelaide,[1] the Australian Broadcasting Company's fourth regional station (after Rockhampton, Newcastle and Corowa).[2] It was initially provided with a 6.25/7 kW STC transmitter,[3] on a frequency of 635 kHz, and at 7.5 kW aerial power one of Australia's two most powerful broadcast stations, with 2CO Corowa.[4] In 1935 the station's frequency was regularized to 640 kHz, and in 1978 to 639 kHz, following the new standard 9 kHz spacing. The original antenna, suspended between two 56 m masts 80 m apart was in 1962 replaced with a guyed mast antenna 190 m in height.[5]

From the outset programmes were fed to Crystal Brook from Adelaide by landline, mostly a "split" of the 5CL programme, but with occasional substitute material provided.[6] From 1937 5CK's programme was mostly a "split" of 5CL's new sister station 5AN, with its greater emphasis on sport, current affairs and light entertainment.[7] A differentiated programme for the regional network was to develop later. Locally produced programmes began in 1952 with the opening of ABC studios in Port Pirie.[8]
