In 1968, an FM station was added as WKIT at 102.3 MHz. At first, the two stations simulcast their programming. Then briefly it took the WKFI call letters until the early 1970s when the call sign changed to WDHK with an adult contemporary format. That format remained throughout the 1970s and 1980s when the call sign was switched to WSWO-FM in 1982 and then playing new country in 1997. It became classic country in 2003 as a brief AM/FM simulcast of WBZI until WSWO-FM was sold to EMF Broadcasting becoming WKLN, the southwest Ohio repeater of K-LOVE, a national Christian Contemporary format.
On March 23, 2018, WKFI rebranded as "Real Roots Radio".[3]
