CKBD is a radio station in Vancouver, British Columbia, Canada. It broadcasts at 600 kHz on the AM dial. As of 2007, the station is owned by the Jim Pattison Group and airs an adult standards format promoted as "Unforgettable 600 AM Adult Favourites". Founded in 1923, in the past the station has broadcast other kinds of material on other frequencies, under the call signs CFXC, CJOR, and CHRX.
CJOR increased its transmission power to 1000 watts in 1941, moving its transmitter site to Lulu Island, where it is located to this day (making it the oldest broadcast site in the vicinity in continuous operation). In 1944, it became the Vancouver affiliate of Canadian Broadcasting Corporation's (CBC) Dominion Network, then increased power again to 5000 watts in 1947 with two 280-foot towers at a site in Richmond; that same year, Chandler established CJOR Ltd. to run the station.
In 1961, CJOR further increased power to 10,000 watts (and three towers), and became an independent station the following year after CBC ceased the Dominion Network's operations. Following Chandler's death in 1964, Pattison acquired the station the following year after the Board of Broadcast Governors (predecessor of the Canadian Radio-television and Telecommunications Commission, or CRTC) decided not to allow station parent CJOR Ltd. (by then owned by Chandler's widow) to renew the licence, but requested that it find a new buyer for CJOR.
On October 31, 1983, with the pending demolition of the Grosvenor Hotel on Howe Street, CJOR relocated from the Hotel's basement to its present studios at 1401 West 8th Avenue. In 1988, CJOR dropped its talk radio programming, adopting a classic rock format with the new call sign CHRX. In 1994, it switched formats and call signs again, adopting its current CKBD calls and the on-air brand The Bridge for Canada's first contemporary Christian music station. In 1998, the station changed to its current programming format.
On May 30, 2008, CKBD was given approval by the CRTC to move to 100.5 MHz on the FM dial. As part of its move to FM, CKBD plans to switch from its longtime easy listening/MOR format to adult album alternative with a new call sign CKPK-FM. The date for the frequency switch has not yet been announced.
