The station adopted its current call sign and format in 1990, after the three stations were acquired by Pelmorex Radio Network. Pelmorex sold the stations in 1998, when Telemedia acquired CJMX, and 1999, when Haliburton Broadcasting Group acquired CHYC and CHNO. Haliburton subsequently converted both stations to FM after receiving approval from the CRTC on August 31, 1999. In 2000, the stations first aired on FM and discontinued their old AM signals. CHYC moved to 98.9 FM in early 2000 and simulcast on AM 900, until it left the air on March 31 of that year after the licensee resolved a technical problem relating to the implementation of the new FM transmitter.
