Owned and operated by Radio Témiscamingue (a non-profit organization), it broadcasts on 93.1 MHz with an effective radiated power of 18,400 watts and a peak effective radiated power of 34,000 watts (class B) using an omnidirectional antenna.

The station operates a small relay, CKVM-FM-1 in Témiscaming, which broadcasts on 92.1 MHz with an effective radiated power of 10 watts (class LP) using an omnidirectional antenna.

The station went on the air on January 7, 1950, on 710 kHz, originally using 1,000 watts full-time (and using a directional antenna at night).

[1][2] CKVM was widely known for failing to follow its nighttime technical parameters by operating at night with 10,000 watts omnidirectional, therefore causing interference to American clear channel station WOR in New York City.

The station admitted this situation during a Canadian Radio-television and Telecommunications Commission (CRTC) public hearing in 2001.
