Licensed to Waupaca, Wisconsin, United States, the station is currently owned by Donald Grassman and Keith Bratel, through licensee Tower Road Media.

The station began broadcasting on April 29, 1956, under founding owner Dorothy Laird.

For many years, WDUX simulcast the contemporary music format of sister station WDUX-FM (92.7).

In February 2020, Ben and Dorothy Laird's son, Bill Laird, would retire from broadcasting and sell WDUX and WDUX-FM to Tower Road Media, whose principal owners have stakes in other stations in Northeast Wisconsin and Iron Mountain, Michigan.

[3] By that May, when WDUX-FM would change formats from adult contemporary to classic hits, WDUX would temporarily leave the air to update its broadcast facilities.
