The station was established in 1977 as a local rebroadcaster of Vancouver's CBU, replacing private CBC affiliate CFJC (now CKBZ-FM).

CBYK switched to CBTK-FM Kelowna after regional programming for the Southern BC Interior commenced from that station in 1987.

[6] The CRTC subsequently issued a notice that it had approved an application by the CBC to change the local programming source of its Radio One transmitter in Revelstoke from Kamloops back to Kelowna.

[8] CBYK-FM produces its own local morning show, Daybreak Kamloops, which began October 9, 2012, hosted by veteran broadcaster Shelley Joyce.

[5] The station continues to carry CBTK-FM's local afternoon show, Radio West with Sarah Penton, which airs across the whole interior of British Columbia.
