WTSO (1070 AM, "1070 The Game") is a commercial radio station in Madison, Wisconsin, known as "1070 The Game." The station is owned and operated by iHeartMedia, Inc., and airs a sports radio format. The offices and studios are on South Fish Hatchery Road in Fitchburg (but using Madison as its mailing address).
By day, WTSO is powered at 10,000 watts. Because 1070 AM is a clear-channel frequency reserved for Class A station KNX Los Angeles, at night, to avoid interference, WTSO must reduce its power to 5,000 watts and use a directional antenna with a six-tower array. (WTSO must also protect a former Class A station on 1070 AM in Moncton, New Brunswick, even though it switched to the FM band.) WTSO's transmitter is off East Tower Road in McFarland.
