CKOC is the oldest continuously-operating radio station in Canada, on the air since May 1, 1922. Station CHAB, in Moose Jaw, Saskatchewan, began broadcasting a week earlier, on April 23, 1922, and is still on the air today -- but was shut down for a period of time in 1933 before re-opening.
Originally, CKOC's station was based in the Lower City at the corner of King William and John Streets and was an offshoot of the Wentworth Radio and Supply Company owned by Herb Slack. He figured he could sell more radios if he also owned a radio station and in the spring of 1922 the station became only the third radio station in all of Canada. Other broadcast locations over the years for CKOC include, the 11th floor of the Royal Connaught Hotel in the downtown core, the Lister Block building on James & King Williams Streets and the a studio on Garfield Avenue near King & Sherman Avenue North. During its early years, the station broadcast on a number of frequencies, including 880, 630 and 1120 kHz; the station moved to its current frequency of 1150 in 1941.
Later History: Top 40 and Oldies formats
CKOC featured a Top 40 music format from 1960 to 1992, and increased its power to 50,000 watts in 1979.
On February 17, 1992, after a countdown of the Top 500 hits of all time (a long-running annual tradition at the station), CKOC debuted "Oldies 1150" with the new calls CKMO ("More Oldies"). However, on April 2, 1993, the station reverted to the heritage CKOC calls, admitting that dropping the calls in the first place had been a mistake and that the station's listeners wanted the original calls back. The station mentions its Top 40 heritage on the air as part of the current oldies format, with liners such as, "The station that played 'em then... plays 'em again." The current branding started sometime in late 2006.
CKOC currently airs a schedule of primarily local programming during the day and evening, with Program Director Ted Yates doing morning 6am-12pm, and long-time station personality Rockin' Ray Micheals handling 12-7pm, with the station automated on overnights. Syndicated programming includes "Elvis Only" and reruns of the 1970s-era American Top 40 on weekend evenings.
In mid-June 2013, after Vinyl 95.3 switched formats from Classic Hits to hot AC, CKOC added more 1970's and 1980's music to its lineup. It's the first time in the station's history that any music later than the 1970s was played on the station.
CKOC has suffered from much co-channel interference from CJRC in Gatineau, Quebec at night, particularly in Southwestern Ontario and north of Toronto which received a relatively clear signal for CKOC during the day. In these areas, CKOC was almost impossible to pick up on some nights due to CJRC. This interference was remedied in Spring 2007, when CJRC moved to the FM dial and closed the AM signal.
