KSTU, virtual channel 13 (UHF digital channel 28), is a Fox-affiliated television station licensed to Salt Lake City, Utah, United States. The station is owned by the E. W. Scripps Company, as part of a duopoly with Provo-licensed Ion owned-and-operated station KUPX-TV (channel 16). KSTU’s studios are located on West Amelia Earhart Drive in the northwestern section of Salt Lake City, and its transmitter is located on Farnsworth Peak in the Oquirrh Mountains, southwest of Salt Lake City. The station has a large network of broadcast translators that extend its over-the-air coverage throughout Utah, as well as portions of Nevada.

As an independent station
The station first signed on the air on October 24, 1978 under the ownership of Massachusetts-based Springfield Television, which also owned NBC affiliate WWLP in Springfield, Massachusetts, and ABC affiliate WKEF in Dayton, Ohio. It was the first independent station in Utah, as well as the first new commercial station to sign on in Salt Lake City since KUTV (channel 2) hit the airwaves 24 years earlier.

Salt Lake City had a fairly long wait for an independent station compared to other cities of its size. It had enough of a population base to support one since the early 1960s. However, the Salt Lake City market is one of the largest in a geographic area and most mountainous markets in the country, covering all of Utah and large slices of Idaho, Nevada, and Wyoming. The market’s three commercial stations, as well as PBS members KUED and KBYU-TV, all needed massive networks of low-power translators to cover it.
