WWHN is a radio station licensed in Joliet, Illinois, serving the Chicago metropolitan area with an urban adult contemporary format.

[5] Because it shares the same frequency as "clear channel" station WLAC in Nashville, Tennessee, WWHN operates during daytime hours only.

[1] Its call sign stood for "Joliet Radio Corporation", the station's owner at the time.

[6][7][8][9][10] William G. Barr hosted a twice-weekly radio program on WJRC from November 11, 1986, until his death in February 1987.

[20][21] In 1992, the station was simulcast on 102.3 WTAS in Crete, Illinois, as well as 105.5 KWHN-FM and 1580 KLVU in Haynesville, Louisiana.
