CKMF-FM (94.3 MHz) is a French-language Canadian radio station located in Montreal, Quebec, owned and operated by Bell Media.

CKMF-FM broadcasts with an effective radiated power (ERP) of 41,400 watts as a Class C1 station, using an omnidirectional antenna from the Mount Royal candelabra tower at 297.4 meters (976 ft) in height above average terrain (HAAT).

Its studios and offices are located at the Bell Media Building at 1717 Rene-Levesque Boulevard East in Downtown Montreal.

Classical music ended in 1970 and the call sign was changed to CKMF-FM on May 1, 1971,[2] airing an automated Top 40/CHR format.

One of the station's biggest on-air personalities of the disco era was the openly gay Douglas Coco Leopold, whose trademark was his local trendsetting lists of who and what was "in" and "out" of fashion.

As was fictionalised in the 2010 Canadian film Funkytown, Montpetit's popularity as an influential DJ and promoter was tarnished by being named as the prime suspect in the 1982 murder of a model in New York City (which would not be confirmed until 2002), and would prompt Leopold to criticize fellow air staffer Montpetit on air publicly.

In 1987, Montpetit died of a drug overdose in Washington, DC, just months after station management fired him after he showed up drunk and appeared too incoherent to do an air shift.

The move reunited the two stations in the same facility for the first time in a decade as CJMS had never relocated to Roy Street in the 1970s and had instead stayed on Berri ever since.

However this plan was notified internationally, which explains why the United States Federal Communications Commission's FM Query webpage erroneous claims that CKMF-FM has a power of 75,000 watts.
