On May 7, the CBC was authorized to open a new FM station at Calgary with a rebroadcast transmitter at Edmonton. The new station would broadcast programming originating from Radio-Canada’s La Chaîne culturelle as well as a minimum of 20 minutes of local programming per week. The Calgary transmitter would operate on a frequency of 89.7 MHz with an effective radiated power of 100,000 watts. The transmitter at Edmonton would broadcast on 90.1 MHz with an ERP of 100,000 watts.

On December 12, the CBC was given approval to decrease power for the Calgary transmitter from 100,000 to 10,000 watts. The Department of Industry determined that the use 100,000 watts would create interference and was not acceptable to Nav Canada.

On June 22, the CRTC approved the CBC's request to modify the technical parameters of the transmitter CBCX-FM-1 Edmonton by moving that transmitter to the site currently occupied by CHFA-10-FM, More... by moving that transmitter's frequency from 90.1 MHz (channel 211C1) to 101.1 MHz (channel 266A) and by decreasing that transmitter's ERP from 100,000 to 3,931 watts (non-directional antenna with an EHAAT decreasing from 193 to 123.7 metres). The Commission also approved the CBC's request to modify the technical parameters of the transmitter CHFA-10-FM Edmonton by moving that transmitter to the site currently occupied by CBCX-FM-1, by moving that transmitter's frequency from 101.1 MHz (channel 266A) to 90.1 MHz (channel 211C1) and by increasing that transmitter's ERP from 3,931 to 100,000 watts (non-directional antenna with an EHAAT increasing from 123.7 to 193 metres).

CBCX-1 moved from 90.1 MHz to 101.1 MHz. CHFA 680 took over the old 90.1 frequency. The 101.1 frequency had been used by CHFA-10, the former nested repeater for CHFA 680.
