The station first signed on the air in 1964 under the call letters WRJC, under the leadership of Richard C. Bakalars. The station was licensed as a "daytimer" on 1270 kHz, meaning it was required to cease broadcasting at sunset to prevent interference with other stations on the same frequency. In its early decades, WRJC focused on "Full Service" programming, including local agriculture reports, high school sports, and local news tailored to the Mauston and New Lisbon areas.

In 1969, an FM sister station was launched as WRJC-FM (92.1), which expanded the station's broadcast reach beyond the immediate Mauston area.
