which is licensed to Milwaukee and transmits from the WTMJ-TV/WKTI tower just north of Radio City. WTMJ broadcasts with 50,000 watts during daytime hours, and 10,000 watts during nighttime from a six-tower site in Union Grove, south of Milwaukee. Its daytime signal can be heard in much of eastern Wisconsin and as far away as Chicago. Four towers are used during the day, providing city-grade coverage to most of eastern Wisconsin (including Madison and Green Bay) and northern Illinois, with most of the Chicago area getting at least a grade B signal. At night, power is fed to all six towers in a directional pattern, concentrating the signal in Milwaukee, Green Bay, and Chicago. The station also regularly rates outside the Milwaukee market, doing so in Sheboygan despite that city being within its own radio market.
