 WKLO provided competition to Louisville's main Top 40 station, WAKY-790 (now WKRD).In 1979, 1080 became WKJJ, a 24/7 delayed broadcast of its FM sister WKJJ-FM (99.7 FM, now WDJX).Afterward, it became WCII with several formats, most notably country music, oldies and Christian music, before returning to a simulcast of its FM sister and their Top 40 format in September 1988 (though it would briefly break away for an all-news format).
