KTTW


KTTW, virtual and VHF digital channel 7, is a Fox-affiliated television station licensed to Sioux Falls, South Dakota, United States. The station is owned by a group of local investors. KTTW's studios are located on West 11th Street in Sioux Falls, and its transmitter is located in Rowena, South Dakota.
KTTM in Huron operates as a full-time satellite of KTTW; this station's transmitter is located near Alpena, South Dakota. KTTM covers areas of south-central and southeastern South Dakota that receive a marginal to non-existent over-the-air signal from KTTW, although there is significant overlap between the two stations' contours otherwise. KTTM is a straight simulcast of KTTW; on-air references to KTTM are limited to Federal Communications Commission -mandated hourly station identifications during programming. Aside from the transmitter, KTTM does not maintain any physical presence locally in Huron.

History

The station signed on May 29, 1987 as the first non-Big Three network commercial station in South Dakota. It has been a Fox affiliate for its entire existence. For its first six years on the air, it was effectively South Dakota's first general entertainment independent station. Fox didn't air a full week's worth of programming until 1993, and until then most early Fox affiliates were programmed as independents. Satellite station KTTM signed on in 1991 to serve the western portions of the Sioux Falls area that could not get a clear signal from KTTW.
In early 1996, Rapid City-based KEVN-TV announced that it would switch from NBC to Fox once its affiliation contract with NBC expired in July of that year. Prior to the switch, KTTW was the only Fox affiliate to be based in South Dakota, while the western portion of the state received the network's programming via either Foxnet or Denver-based KDVR.
KTTW aired on analog channel 17 since its inception, then took advantage of the digital transition in 2009 to use their physical digital channel 7 as their permanent PSIP virtual channel to better brand themselves. The station has never had a news operation, nor contracted with another station to provide a newscast.
