CKOC (AM)

From Wikipedia, the free encyclopedia

CKOC is a Canadian radio station, broadcasting at 1150 AM in Hamilton, Ontario. The station airs an oldies format branded as 1150 CKOC and is owned by Standard Broadcasting.

CKOC is one of the oldest radio stations in Canada, on the air since May 1, 1922. 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. 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, 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 first applied for an FM station in 1968, but the FM station did not take to the air until 1986 as adult contemporary station CKLH.

CKOC airs the syndicated Wolfman Jack Radio Program.

CKOC suffers from much co-channel interference from CJRC in Gatineau, Quebec at night, particularly in Southwestern Ontario and north of Toronto, which receive a relatively clear signal for CKOC during the day. In these areas, CKOC is almost impossible to pick up on some nights due to CJRC. This interference may be remedied in Spring 2007, when CJRC moves to the FM dial and closes the AM signal.
