In the ninties the station was known as "The Wave" with the call letters WVVW and an Oldies format. On December 29, 1999, Citadel purchased the station and flipped formats to hard rock as "Rock 102" and shortly thereafter the calls were changed to WAXK. The switch to Classical Hits took place in February, 2002 with the slogan "XL 102", the calls WUXL and the syndicated Bob & Tom Morning show.
In March 2003, XL 102 flipped formats to Adult Comtemporary music and changed its calls to WXLM "MIX 102".
The next format was news/talk with the station commencing a simulcast of sister station WSUB AM 980 in April 2005. The station officially became News-Talk 102.3 FM in late June 2005, after WSUB went Spanish as Magia 980.
On March 17, 2008, WMOS switched frequencies from 104.7FM to 102.3FM. At the same time, News/Talk 102.3FM WXLM switched frequencies to 104.7FM. Both formats remained the same.
