KCTR-FM (102.9 MHz, "Cat Country 103") is a commercial radio station in Billings, Montana. KCTR airs a country music format.^[2] Licensed to Billings, Montana, United States, the station serves the Billings area. The station is currently owned by Townsquare License, LLC.^[3]

102.9 FM began broadcasting in August 1979 as KOOK-FM, sister station to KOOK (970 AM). The new outlet used Schulke Radio Productions's automated beautiful music format with just eight commercial units an hour.^[1]

KOOK-AM-FM was acquired by "Major" Dan Miller, a 25-year employee of the stations, and the Mesa Broadcasting Company of Chicago in 1983.^[4] Citing low support, KOOK-FM flipped to country as KBIT on January 16, 1984.^[5] The station returned to KOOK-FM on November 4, 1985, as part of a format and call sign trade between the AM and FM stations that moved country to AM and the former contemporary hit radio format on KOOK to FM.^[6] The move failed to generate increased interest in the stations, and Miller left the management group and KOOK.^[7]

After the FM station improved in listenership over the course of 1987, KOOK-KBIT was sold again in 1988, to Citadel Associates of Phoenix.^[8] Citadel wasted little time changing the format on KOOK-FM back to country; KOOK and KBIT began simulcasting as KCTR-AM-FM, retiring the KOOK call letters from Billings radio after having been used since 1951.^[9]

In October 2007, a deal was reached for KCTR-FM to be acquired by GAP Broadcasting II LLC (Samuel Weller, president) from Clear Channel Communications as part of a 57 station deal with a total reported sale price of $74.78 million.^[10] What eventually became GapWest Broadcasting was folded into Townsquare Media on August 13, 2010.^[11]
