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 mentioned 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 "Good Times, Great Oldies" branding started sometime in late 2006.
