The station went on the air as WTCO in 1948, broadcasting at 1150 AM. The station was headed by H.T. Parrott and James Schacklette with the group South Central Broadcasting. In 1950, Redman Turner would lead Taylor County Broadcasting to launch a second AM station in Campbellsville, WLCK at 1450 AM. Four years later, Clifford Spurlock would become manager and part-owner of WTCO, and would arrange a merger between the two stations in 1945. The more-powerful 1450 frequency was kept, with call letters changed to WTCO. The 1150 allotment would later be relocated to Munfordville, Kentucky.
WTCO would gain a companion on the FM band at 104.1 MHz in, providing overnight service for WTCO as it was a daytime-only station. Local businessman Lowell Caulk would become majority-owner of WTCO-AM-FM in 1978, and would make wholsesale changes in 1980. Both stations relaunched as WCKQ and adopted a rock music format as Q104. The simulcast would be maintained for only a few years, as in 1981, WTCO-AM was relaunched as WKXJ, with a country music format under the branding Kicks Country.
In 1985, Caulk sold WCKQ and WKXJ to George E. Owens Jr. and his Heartland Broadcasting. Three years later, Owens would lead the station to change its call letters back to the original WTCO.[3] The station and WCKQ were purchased by Commonwealth Broadcasting, owned by Steven Newburry, in 1997. The two, plus WGRK-FM, would be sold in 2014 to Forcht Broadcasting, owners of the WAIN stations in nearby Columbia, Kentucky.[7]
