to CFCF the following year.) Top 40 era On January 1, 1970, CKGM changed its format to become a full-time Top 40 station. The ratings quickly climbed, with CKGM beating direct competitor CFOX, also a full-time Top 40 station, in the Fall 1970 BBM ratings. CKGM would quickly become one of North America's legendary AM Top 40 stations. Legendary morning drive time host Ralph Lockwood, formerly of CFOX, made his debut on CKGM on October 2, 1972. He would remain with the station until late 1981. In 1975, CKGM introduced "La Connection Française", referring to a trio of bilingual personalities (Rob Christie, Marc Denis and Scott Carpentier) which used both English and French on the air and played songs of both languages. As CKGM remained an English-language station, this resulted in French-language stations complaining to the Canadian Radio-television and Telecommunications Commission (CRTC) and even refusing to observe quotas of Francophone music. On-air bilingualism would remain a distinctive CKGM feature until stringent CRTC regulation forbidding it (and also enforcing quotas on the Francophone side) went into effect on January 1, 1980. CKGM got a record-high number of listeners among English-language stations in Montreal according to the Fall 1976 BBM ratings that were released on December 13 of that year, thanks in part to the large numbers of Francophones who listened to the station. (Almost 40% of CKGM listeners were French-speaking.) During its Top 40 era, CKGM was one of a handful of Canadian radio stations to carry the syndicated countdown show American Top 40 with Casey Kasem. Sale to CHUM Limited On August 20, 1985, CKGM and sister station CHOM-FM were sold to CHUM Limited. CKGM switched its format to gold-based adult contemporary under the "Lite Rock, Less Talk", and "Favourites of Yesterday and Today" monikers a few months later, on January 15, 1986. The station returned to a Top 40 format at 5 p.m. on February 10, 1989, changing its call sign to CHTX in an attempt to distance itself as far as possible from its earlier days as a Top 40 station that even included adopting a new phone number. CHTX identified itself on-air as 980 Hits, and also referred to itself as "the station that plays the most music allowed by law" (in reference here to CRTC regulations that limited hit music on FM stations). Anecdotal evidence suggests that at least some listeners wondered if there was, in
