WDRT started as an Internet audio stream on June 30, 2005, while Driftless Community Radio, Inc. (DCR) was waiting for the US FCC to accept applications for new non-commercial radio stations. radiodriftless.org (now defunct) streamed audio, both live and pre-recorded for four years.
After negotiating a buyout with a competitive license application in Sparta, Wisconsin, DCR was granted a construction permit by the FCC on March 24, 2009. Per FCC rules, DCR had three years to complete the construction of the station.
In September 2009 DCR leased a 1,400-square-foot space on Viroqua's Main Street for its studios, and commenced studio construction.
A year later on September 17, 2010, WDRT began broadcasting on its assigned frequency, 91.9 MHz and has broadcast (more or less) continuously since then.
In 2022 WDRT Increased It's Effective Radiated Power to 3000 Watts
