[2] The FCC granted the application on November 18, and station WLYK started broadcasting in August 1969 from a studio on Main Street in Milford and a transmitter at Dry Run.

Along with other programming changes, Cincinnati radio personality Bud Stagg was hired as a morning announcer,[5] and ratings increased by 50 percent.

The latter proved particularly popular, attracting new advertisers and listeners (though not much new revenue) and motivating the station to sign a three-year contract extension with the school for 1983, 1984, and 1985.

[10] After Samuels reached a deal to sell WLYK in March 1982 and then called it off that same week,[11] he sold it to the Cincinnati Broadcasting Company, led by Richard Hallberg and Bob DeLuca, in 1984.

[12] Despite initially planning to keep the beautiful music format, the new owners slowly moved the station to adult contemporary and changed the call letters to WRXY in March 1985.

[14] The third major change within less than 18 months came in 1986, when WRXY went to the syndicated "Format 41" soft adult contemporary programming from Transtar Radio Networks, retaining a local host in morning drive, and renamed itself WJOJ "Joy 107".

[25] At year's end, the station dropped "The Heat" to become "The Power Pig", cloning a moniker used to great success by Jacor leader Randy Michaels at WFLZ-FM in Tampa, promoting "zero DJs and no music by dead guys" while seeking to run WZRZ (96.5 FM) out of the rock format.

As a result, in April 1993, the Power Pig came to an end and was replaced by an alternative rock format as "Channel Z", competing with WOXY (97.7 FM).

[32]) In January 1999, after nearly a decade running the Milford station, Jacor acquired it outright alongside WSAI and WCKY from Middle Market Broadcasting, which had leased all three.

[40] During the July 4th weekend of 2023, WKFS relaunched its CHR format in a manner mirroring similar format shifts done at WBBM-FM in Chicago and WPOW-FM in Miami, reducing current songs down to as low as three to four an hour and focusing primarily on "throwback" CHR hits from the 2000s and 2010s, with sweepers announcing "the Kiss you love is back" and introducing the temporary slogan "Your Summer Party Station".

[41] WKFS has been broadcasting in HD Radio since January 2006; its first HD2 subchannel offering was a classic hip-hop format, part of an expansion of multicasting across the Clear Channel portfolio.
