CKCH was a radio station which operated at 970 kHz on the AM band in Hull, Quebec, Canada from 1933 to 1994.
Due to CKCH's modest power, Radio-Canada also relied on the 50,000-watt signal of Montreal's CBF to reach the National Capital Region's francophones until it signed on an Ottawa station of its own, CBOF.
In 1984, CKCH's then-owner, Telemedia, received approval from the CRTC to renew its licence for another five-year period, from October 1, 1984 to September 30, 1989.
On September 30, 1994, Telemedia and Radiomutuel merged their AM operations in Quebec, creating a new company, RadioMedia.
But in doing so, the new combined company closed CKCH, along with CJMS, CJRP, CJMT, CJRS, and CJTR, as they felt it was not economical to continue operations of those stations.
