CKLM was a French-language Canadian radio station located in Laval, Quebec (near Montreal). It operated from 1962 to 1994. The station broadcast on 1570 kHz with a power of 50,000 watts full-time as a class B station, using a directional antenna with different patterns day and night (the nighttime pattern being significantly tighter). While the station's signal was not particularly impressive from a strictly local point of view, the station was received by many DXers in Europe and was considered there as one of the "easy" targets for Transatlantic DX.
