WLXG signed on as WKLX in 1946. WKLX merged with WLEX (1340) by 1952, keeping the 1300 kHz frequency and getting the WLEX calls. Much of the WKLX airstaff (like Claude Sullivan and Artie Kay) went to WVLK.
In 1958, WLEX was sold to Roy B. White and the call letters were changed to WBLG ("Bluegrass").
Up until 1978, WBLG was 1000 watts non-directional in the daytime, and 1000 watts directional at night. Daytime power was upped to 2500 watts in '78.
WBLG became country-formatted WTKC in 1979.
In 1986, county music gave way to oldies and the calls were changed to WLXG.
In 1990, WLXG switched to a news-talk format. In the Mid-2000s, WLXG picked up a sports talk format and became affiliated with ESPN Radio.
