WMDX (1580 AM) is a commercial radio station licensed to Columbus, Wisconsin, and serving the Madison metropolitan area radio market. The station is owned by Sage Weil, through licensee Civic Media, Inc. Branded as "92.7 WMDX", the station airs a progressive talk radio format WMDX carries live locally programmed news and talk programming for most of the day, originating from studios located on State Street in downtown Madison as well the Racine studios of sister station WAUK. The station also carries live syndicated programming from Stephanie Miller and Thom Hartmann. WMDX also serves as the flagship station of the Civic Media Network, a statewide news network with affiliates across Wisconsin.
WMDX transmits 5,000 watts daytime, using a directional antenna that provides city-grade coverage of the northern and eastern portions of the Madison area including Columbia and Dodge counties. As 1580 kHz is a Canadian clear channel frequency, WMDX must protect Class A CKDO Oshawa, from interference. During critical hours, WMDX drops to 800 watts, and after sunset, to only 4 watts, which roughly covers only the city of Columbus. The transmitter is off Parpart Road in Hampden, Wisconsin.[3] All programming is simulcast on 250-watt FM translator 92.7 W224EG which affords WMDX 24/7 city grade signal to most of Dane County .[4]
