100.9 FM came to the Lebanon and Springfield airwaves in 1979 with 3,000 watts and an easy listening format. The frequency was owned by six Elizabethtown businessmen with the Lebanon-Springfield Broadcasting Company. It was one of two stations licensed to serve Marion and Washington counties, the other being AM 1590 WLBN; which hit the air in 1953.

     Since the station was licensed to serve Lebanon and Springfield, Kentucky, General Manager the late J.T. Whitlock came up with an idea for the call letters: L-standing for Lebanon, S-for Springfield and K-standing for Kentucky. The station would later increase to 10,000 watts and change to a country format.

     In 1985, WLSK was sold to J.T. Whitlock, Cherry Gibson and J.B. Crawley. In 1997 Commonwealth Broadcasting bought the station. The format was changed again to Lite-Rock 100.9 WLSK and was very well received by the tri-county area. In February of 2001 the format changed to Classic Hits and was well received.

     To date WLSK- FM is still attracting more and more listeners in central Kentucky as the station recently went to 25,000 watts and is now MIKE 100.9.  What is Mike 100.9?  The best hits from the 80's, 90's and whatever we want to play next!
