WTDY (1670AM) is a news/talk-formatted radio station licensed to Madison, Wisconsin. The station is owned by Mid-West Family Broadcasting.

Progressive talk programmingEdit

Though WTDY does carry nationally syndicated programming in the evening and overnight hours, the station's emphasis is on its all-local daytime lineup, which consists of conservative, liberal and nonpartisan opinions. Among its syndicated offerings are Alan Colmes and Phil Hendrie.

In the fall of 2004, in a preemptive strike against WXXM, the station briefly positioned itself as progressive talk, and briefly aired Stephanie Miller and Ed Schultz.

On November 21, 2012 there were mass layoffs and a switch to all Christmas music. A non-political talk format,perhaps sports, will debut after the holidays.


WTDY began operating in 1948 at the 1480 frequency under the call letters WISC, which were eventually changed to WISM. For years, WISM was the popular Top 40 radio station in Madison. In the mid-1980s, the WTDY call letters were adopted, which originally stood for "Today Radio," a format that featured a mix of music, news, sports and weather.

WTDY was an early carrier of both Rush Limbaugh and Coast to Coast AM with Art Bell.

By the late 1990s, WTDY would simulcast at both the 1480 and 1670 (Extended AM) frequencies before moving full-time to 1670 in the early 2000s. (Sister station WLMV now occupies the 1480 frequency.)


Currently, WTDY broadcasts from its Madison, WI, studios at 730 Ray-O-Vac Dr. on the far west side of Madison. Its single tower is located on Syene Rd. in the nearby Town of Madison, sharing a site with its sister station WLMV.
