WTSO (1070 kHz "The Big 1070") is a commercial AM radio station in Madison, Wisconsin. The station is owned and operated by iHeartMedia, Inc., and airs a sports radio format. Since Summer of 2014, WTSO is simulcast on FM translator W265CV at 100.9 MHz.
WTSO's offices and studios are on South Fish Hatchery Road in Fitchburg (but using Madison as its mailing address). The transmitter is off East Tower Road in McFarland. WTSO operates at 10,000 watts by day. But at night it reduces its power to 5000 watts, using a directional antenna, because AM 1070 is a clear-channel frequency. WTSO must protect Class A stations KNX Los Angeles and CBA Moncton, New Brunswick, from interference, so the nighttime signal is nulled away from the west and the east. (CBA switched to the FM dial in 2008 but WTSO still must protect the Canadian AM station's former coverage area.) WTSO's FM translator operates at 250 watts from a 243-meter (798 foot) tower off South Pleasant View Road in Madison.
WTSO broadcasts local sports call-in shows during weekday morning and afternoon drive times. "Lucas in the Morning," hosted by longtime Wisconsin Badgers radio analyst and Madison sports columnist/reporter Mike Lucas, is heard from 6 to 8AM. "The Mike Heller Show" airs from 3 to 6PM. WTSO's midday schedule features nationally syndicated sports shows hosted by Dan Patrick and Rich Eisen. At night and on weekends, programming from Fox Sports Radio and NBC Sports Radio is heard. Since the start of 2013, the station's local sports shows have been simulcast on Milwaukee sister station 920 WOKY, an unusual situation where a station in a smaller media market provides the simulcast for the larger market station.
