102.3 FM signed on as WLRS in 1964 as a stand-alone FM station for Louisville Radio School. The station was used as a training ground for the school's broadcast students in its early years. In the late 1960s, station owner Clarence Henson entered into an agreement to sell WLRS to crosstown AM Top 40WAKY, but the deal fell apart when WAKY did not meet the six-month deadline to complete the transaction. By 1970, WLRS was noted as being one of only nine stand-alone FMs in the state of Kentucky. WLRS went to first place in the Arbitron ratings in 1978. By that time, the station was Album Rock, a format that the station had adopted for many years. However, by 1981, WLRS was beaten by rival Album Rock station WQMF in the ratings, and in 1984, the station switched to a Top 40/AOR format or CHR for short as "The Flamethrowing LRS 102". The station was adding pop and urban artists like Michael Jackson and Whitney Houston to its playlist, to fill the void left when WKJJ abandoned Top 40 for Adult Contemporary in 1982 and WJYL dropped Top 40 for urban contemporary in 1984. Eventually, WKJJ switched back to CHR as WDJX, and both WLRS and WDJX battled each other for the next few years before WLRS evolved back to their Album Rock format in the late 1980s, because, at that time, LRS' ratings were poor. On December 26, 1990, at 2 a.m., WLRS began stunting with an electronic countdown. On January 1, 1991, at approximately 9:27 a.m., WLRS flipped to Adult Contemporary as "Mix 102". The first song on "Mix" was "This Is It" by Kenny Loggins. The station still used the legal calls of WLRS, but despite this, complemented its branding with the fake calls, "WMIX". However, the "WMIX" branding was dropped by June 1991, as Withers Broadcasting, which owns two actual WMIX stations in Mount Vernon, Illinois, registered the "WMIX" branding as a registered trademark, and has threatened WLRS with a Cease and Desist letter for use of a trademark without permission. On May 19, 1997, at 6 p.m., after playing "The Last Song" by Edward Bear, WLRS began stunting with a loop of "I Am the Walrus" by The Beatles, as well as promotions for other Louisville radio stations and teaser formats. On May 26, at 1:02 p.m., WLRS flipped to Alternative rock as "LRS 102.3". The first song on "LRS" was "Spoonman" by Soundgarden. On July 30, 1999, at 3 p.m., WLRS flipped to Soft Adult Contemporary outlet "Love 102.3" under the WULV call letters. On May 17, 2002, WULV flipped to Hot AC as "102.3 The Max" WXMA. On August 31, 2017, at Noon, WXMA changed formats to adult hits, branded as "102.3 Jack FM". WXMA is owned by Alpha Media.
