CBM was the longtime English language Canadian Broadcasting Corporation (CBC) anchor in Montreal, Quebec on 940 kHz. Today, 940 in Montreal is occupied with CFNV, which uses a Francophone news/talk format. They were an easy catch in Maryland in the 1980’s. I heard them a few times in Utah and once in Spokane.
In 1983, Lee Fortune of CBM sent the QSL card below for my reception report.
