The stations air the same programming at all times, although both stations produce a portion of the shared broadcast schedule from separate studios. Their contemporary hit radio sister station CFJO-FM also produces programming in both cities, although it serves the region from a single 100-kilowatt transmitter.
The station was launched on February 12, 1950 by Radio Mégantic. Broadcasting on 1230 AM, it was a private affiliate of the Radio-Canada network. François Labbé became president of the company in 1965.
The station moved to 1330 AM in 1976, and disaffiliated from Radio-Canada in 1979. The station moved to its current frequency in 1999.
In April 2014, Montreal-based Attraction Radio announced plans to acquire all of Réseau des Appalaches' stations, including CKLD-FM and CJLP-FM; the decision is currently awaiting CRTC approval.
