The station originally began broadcasting on October 19, 1957 as CKEK at a frequency of 570 kHz on the AM dial. The EK in the call letters stood for East Kootenay Broadcasting Ltd. (Robert A. Reagh). In the 1960s, the stations' slogan was "The Voice of the Rockies".
On July 24, 1972, EK Radio Ltd. received approval to acquire CKEK and CFEK from East Kootenay Broadcasting Co Ltd.
On July 27, 1973, CKEK was authorized to increase its daytime power from 1,000 to 10,000 watts, its nighttime power would remain at 1,000 watts.
By 1984, CKEK was owned by Columbia Kootenay Broadcasting Co. Ltd.
In 1984, CFEK Fernie received approval to add an AM transmitter at Sparwood on the frequency 1400 AM.
In 2000, Monarch Broadcasting Limited (division of Jim Pattison Industries Ltd.) purchased Columbia Kootenay Broadcasting Co. Ltd.
On September 12, 2001, Columbia Kootenay Broadcasting Co. Ltd., a division of Jim Pattison Industries Ltd. Cranbrook, British Columbia received CRTC approval to move CKEK from the AM band (570 kHz) to the FM band at 102.9 MHz, which moved there in 2002 and became CHDR "The Drive".
It is uncertain when CKKI Kimberley was deleted, although the FM transmitters that went on in 2002 reach Kimberley. Also, it is uncertain if CFIW Canal Flats is currently still in operation, as CFIW was last listed in the 2008 CRTC renewals  and is not listed in the 2015 licence renewals (pending approval). As of 2016, CFIW was deleted from the Industry Canada database.
