A
construction permit to construct a low-power television station on
UHF channel 26 in Casper was granted on June 15, 1995, and issued the call sign K26ES. Original owner Charles W. Swaner sold K26ES to Wyomedia Corporation on September 15, 1997; the new owners applied for a license to cover on October 29, 1997, and was granted it on January 28, 1998. Initially, K26ES served as a
translator of
KLWY in
Cheyenne; this brought
Fox programming to Casper, along with a secondary affiliation with
UPN. The station, by then referring to itself as "KWYF," began producing a 9 p.m. newscast on November 3, 2003. On March 8, 2004, K26ES became a full-time UPN affiliate after Fox programming was moved to KFNB; for a time after this change, the station also carried some programming from
Pax. Wyomedia also transferred K26ES' newscast to KFNB. On March 27, 2012, Wyomedia was granted a construction permit for a digital companion channel for K26ES to operate on channel 27; this facility was issued the call sign K27LZ-D. K27LZ-D filed for its license to cover on June 15, 2012 and was granted it on July 16; on June 13, 2013, the call letters were changed to KWYF-LD. On January 26, 2015, KWYF became a
MeTV affiliate. In addition to airing programing from MeTV, it also airs programing from
MyNetworkTV from 7pm-9pm weeknights. Wyomedia Corporation agreed to sell its stations, including KWYF-LD, to Legacy Broadcasting on February 8, 2018. The sale was canceled on October 2, 2018. On October 8, 2019, Wyomedia announced that it would sell its stations to Front Range Television, a subsidiary of Coastal Television Broadcasting Company (run by Bill Fielder). This sale was concurrent with Coastal's purchase of KFNB, the sale of KTWO-TV to Vision Alaska, LLC, and the sale of KGWC-TV to Big Horn Television. The sale was completed on June 1, 2020. By April 2022, the station began airing newscasts from the Coastal-owned and partly-centralized
News Hub, recently acquired from Waypoint Media. ==Subchannels==
