The station was first launched in 1934 as AM 950 CRCK, Quebec City's second-oldest radio station. It was an affiliate of the Canadian Radio Broadcasting Commissionm airing programming in both English and French. It became a part of the Canadian Broadcasting Corporation in 1936. It adopted the callsign CBV in 1938, becoming the second station in Radio-Canada's French radio network. In 1941, CBV moved from 950 to 980 kHz.
In 1974, CBVX-FM, broadcasting Radio-Canada's FM network, was launched. It was initially known as CBV-FM.
On July 4, 1997, the CBC received CRTC approval to convert CBV from the AM band (operating at 980 kHz) to the FM band at 106.3 MHz. After the move to FM, the old AM 980 signal was discontinued. It took over the CBV-FM callsign, and the existing CBV-FM became CBVX.
