WTMJ is an AM radio station in Milwaukee, Wisconsin broadcasting at 620 kHz and at 94.5 FM HD-2. The station was the flagship radio station of the Journal Broadcast Group until April 2015, when it came under its current ownership of the E.W. Scripps Company. JBG also owned the Milwaukee Journal Sentinel, WTMJ-TV and sister radio station WKTI, along with other media assets across the U.S. (WTMJ remains owned with WTMJ-TV and WKTI, with The Journal Sentinel now owned by the spin-off company Journal Media Group). WTMJ maintains studio facilities located on Capitol Drive in Milwaukee (this Art Deco facility is known as "Radio City" in tribute to the New York complex of the same name), and its transmitter is located in Union Grove.
WTMJ Radio airs a format of news, talk & sports. The station also has served as the flagship outlet for Green Bay Packers, Milwaukee Bucks and Milwaukee Brewers games for most of the teams' histories, with Packers broadcasts airing on WTMJ since 1929.
The station broadcasts a 50,000-watt signal during daytime hours, and 10,000 watts during nighttime hours. Due to its signal strength, as well as Wisconsin's flat land (with near-perfect ground conductivity) and its location near the bottom of the AM dial, WTMJ boasts one of the largest coverage areas in the nation. Its daytime "city-grade" signal reaches most of the eastern third of Wisconsin, including Madison and Green Bay, and it provides at least grade B coverage to most of the eastern two-thirds of the state. Additionally, the station provides at least grade B coverage to most of the Chicago area, as well as Grand Rapids, Michigan.
Shortly after the transfer of ownership to Scripps, WTMJ's signal began to be simulcast full-time in HD Radio over the HD2 subchannel of WKTI, allowing the station's sports coverage to be heard full-time in some form on FM.
