fact, a legal limitation on the number of songs radio stations can play. On September 14, 1990, at 5 PM, CHTX moved to 990 kHz, increasing its power to 50,000 watts full-time from a new transmitter site located in Ville Mercier, and converting itself to AM stereo. However, 990 was a class B frequency, requiring the station to use a directional antenna which is slightly directional during the day and extremely directional at night to protect clear channel (class A) stations CBW in Winnipeg, Manitoba and CBY in Corner Brook, Newfoundland and Labrador. The switch occurred one week later than initially scheduled, on orders from the federal Department of Communications, due to the "tense security situation" (the Oka Crisis) in the neighbouring Indian reserve of Kahnawake. Another format change occurred on May 24, 1991, with the new format being oldies, although the station would also air Dr. Laura's syndicated advice show. The station changed its call sign to CKIS and identified itself as Oldies 990. ON January 15, 1996, the station returned to its original CKGM call sign, as the station moved to a talk radio format known as "Talk Radio With Attitude." The station aired mostly syndicated talk shows. For that reason, the station got low ratings, with fewer than 100,000 listeners. The CKIS call letters moved to a Calgary radio station formerly owned by Rawlco, and as of 2009, are now used on a Toronto radio station. When the 1998 Ice Storm took place, CKGM continued to rely on automation, making few efforts to broadcast adapted emergency information. On January 9 of that year, competitor CJAD lost its broadcast towers due to the accumulation of ice. After that station moved temporarily to 1410 kHz using the former facilities of CFMB, CKGM leased its signal to CJAD on a temporary basis, starting on January 22, 1998. (Technically, CKGM left the airwaves and was replaced on 990 kHz by CJAD.) CJAD returned to 800 kHz on May 29, 1998, and after two weeks of simulcast, CKGM returned on June 12, 1998, at Noon. The station took the opportunity to re-launch itself as a largely automated oldies station, again using the "Oldies 990" as its moniker (but keeping the CKGM call sign).
