Rádio Mieux-être (CFAV)

CFAV is a French-language Canadian radio station located in Laval, Quebec, near Montreal. Founded by Gilles Lajoie and Colette Chabot, and operated by Diffusion Laval, Inc. the station broadcasts on 1570 kHz with a power of 10,000 watts as a class B station, using a directional antenna pointing east which has a slightly directional pattern during the day and a much tighter pattern at night. While the station's signal is unimpressive from a local point of view and does not even cover entirely the Greater Montreal area even during daytime, the station has been received by many DXers in Europe and is considered there as one of the "easy" targets for Transatlantic DX.

The station's format evolved from a mix of adult standards and oldies when the station opened on March 9, 2004, to a more traditional oldies format focused on the late 1950s, 1960s and early 1970s in June 2005. Initially identifying itself as "Radio Nostalgie", the station now identifies itself as "Radio Boomer AM 1570".

The 1570 kHz frequency used to be home of the now-defunct CKLM, also located in Laval but using 50,000 watts of power instead of only 10,000 watts. That station opened in December 1962 and went dark in July 1994.

In spring 2007, the sale of CFAV and Diffusion Laval to Pierre Marchand was approved. Since then, the format has been tweaked to include some 80's music as well, especially during weekdays.
