102.3 FM was an Oldies formatted radio station known as 102.3 The Wave and had the call letters WVVE until December 29, 1999, when Citadel Broadcasting purchased the station and flipped formats to Hard rock as ROCK 102. They soon changed calls to WAXK. ROCK 102 flipped to a Classic Hits format under the moniker XL 102 and the WUXL call letters in February 2002. XL 102 featured the syndicated Bob & Tom Morning show. In February 2003 XL 102 was one of two stations that gave away tickets to a Great White Concert in West Warwick, Rhode Island, which ultimately became the scene of one of the deadliest fires in Rhode Island's history. (The other station being Clear Channels's WHJY in Providence, Rhode Island). In March 2003, a few weeks after the fire XL 102 flipped formats to Adult Contemporary music and changed its calls to WXLM. (The format change is rumored to be just a coincidence). As AC formatted MIX 102, WXLM competed against long-time ratings leader Soft Rock 106.5, WBMW. WXLM dumped its Adult Contemporary format and began simulcasting the news/talk format of sister station WSUB AM 980 in April 2005. WSUB began promoting the simulcast in mid-March. . WXLM officially became News-Talk 102.3 FM in late June 2005, after sister station WSUB, went Spanish as Magia 980.

In 2010, the News/Talk format migrated back as WXLM to AM 980, replacing Spanish "Caliente 980" there in 2010 as 104.7 shifted to Hot AC WELJ.
