WAUK (540 AM) is a progressive talk radio station licensed to Jackson, Wisconsin, and serving the Milwaukee metropolitan area.

Salem Communications bought the station in October 2000, and switched initially to a simulcast WYLL Chicago while using the WYLO call letters beginning in early 2001.

In the fall of 2001, the call letters changed to WRRD and the station began operating its own Christian Talk, Preaching format branded as "The Word".

[8] It returned to regular ESPN Radio programming by mid-July 2020 as American professional sports began to resume.

Effective December 30, 2022, the station and the translator were flipped to Michael Crute and Sage Weil's Civic Media, Inc. for $775,668.

On June 4, 2019, Good Karma ended the simulcast and made WAUK mostly a pass-through for the national ESPN Radio schedule, with WKTI becoming a more locally-based sports talk station.

The station also airs play-by-play coverage of Major League Baseball, the College Football Playoff and the NBA from ESPN Radio.

Despite its modest power, WAUK's signal covers a relatively substantial area due to its low frequency and Wisconsin's flat land.
