History
The station first signed on in 1989 as WWAM. In 1990 it changed call letters to WYKY, airing an adult contemporary music format as "Key 100.5." Then in 1998, it changed to WTLX, airing a "hot talk" format as "100X." The 100X schedule included the Howard Stern and Don & Mike shows, along with sports programming from Sporting News Radio and later Fox Sports Radio. By the mid-2000s, the station would morph into an all-sports format, with both national and Wisconsin-based programming. On January 1, 2009, WTLX became a network affiliate of ESPN Radio, whose programming had been airing in Madison on rival station 1070 WTSO. Along with that affiliation change, WTLX's city of license moved from Columbus, Wisconsin, 27 miles northeast of Madison, to the Madison suburb of Monona. According to Jason Wilde on an episode of Wilde & Tausch from December 21, 2021, the radio studio when he joined ESPN Madison was located on Regent Street under the Regent Apartments at 1402 Regent Street in Madison a block east of Camp Randall Stadium. The same episode of Wilde & Tausch also mentions that previous to Pinckney Street the radio studio had been located at the WISC-TV studios at 7025 Raymond Road on the southwest side of Madison. Since January of 2022, the station has operated out of the American Family Insurance SPARK Building located on E. Washington Ave in downtown Madison.
