Commercial (1984–2016) Country (1984–1986) The station was first licensed in 1984. The station held the callsign KRGO, and aired a
country music format, simulcasting sister station
KRGO 1550.
Oldies (1986–1992) On September 19, 1986, the station's callsign was changed to KRPN. As KRPN, the station aired an
oldies format, and was branded "
WKRP".
Hard rock (1992) On February 10, 1992, the station's callsign was changed to KZQQ-FM.
Country (1992–1996) On September 14, 1992, the station adopted a
country music format.
Adult standards (1997–1998) In July 1997, the station began airing the "
Timeless"
adult standards format, and was known as "Sunny 107.9".
Alternative (1999–2000) The simulcast ended in July 1999, when the station became "The Edge", which served as a placeholder format until the station's sale was consummated.
Rhythmic oldies (2000–2001) On January 18, 2000, the station became KFVR-FM, and the station adopted a
rhythmic oldies format as "Fever 107.9" "Utah's Movin' Oldies".
Top 40 (2001–2016) In 2001, the station flipped to a
top 40 format as "Power 107-9", "Utah's Hit Music Station". The
KUDD call letters would be adopted during this time. With trying attempting to go after
KZHT, they added a simulcast on the 103.9 frequency as "KMDG" to better cover the western area of Salt Lake. The general manager named the station "Dianna 107.9" briefly before rebranding as "Power". The station shifted from a
modern adult contemporary format to a
top 40 (CHR) format in 2009. On June 18, 2010, Millcreek, KUDD's owners, sold the station, along with KUUU and KYLZ to Simmons Media Group. Simmons continued to operate KUDD and its sister stations until they were sold to
Broadway Media in 2014. Around this time, the station moved its signal from
Promontory Peak west of
Ogden to
Humpy Peak, allowing for better coverage of the areas south of Salt Lake City, including
Provo. Announcers at the time included Lexi, Banks, MJ, Dylan and Jake Stone.
Non-commercial (2016–present) Adult alternative (2016–2018) On December 2, 2015, Broadway stated that it would donate KUDD to Community Wireless of Park City, Inc., which in turn would move
KPCW-FM down from 91.9 to 91.7 while the
Mix format would move to 105.1. The move took place on March 31, 2016 at 10:51 AM; the last song on "Mix" on 107.9 was "
My House" by
Flo Rida. 107.9 adopted the new callsign
KUMT. On April 25, 2016, KUMT flipped to an adult album alternative format, branded as "107.9 The Mountain". On May 6, 2016, KUMT ended its "Mountain" AAA format after ten days with the format. After a few days of stunting, KUMT would return to AAA and the "Mountain" branding, now under the operation of Community Wireless.
BYU radio (2018–present) On April 26, 2018,
Brigham Young University announced it would acquire KUMT for an undisclosed amount. The university uses KUMT as a full-time outlet for its campus-run radio network
BYU Radio. The university had originally planned to drop
KBYU-FM's
classical music format in favor of BYU Radio, but the plans were met with criticism by listeners. The purchase was consummated on August 31, 2018, at a price of $875,000. BYU Radio programming officially began airing on the station September 17, 2018. KUMT airs all BYU Radio programming except football and men's basketball (which are broadcast by
de facto commercial sister station
KSL). In 2019 KUMT officially became the flagship station for BYU women's soccer followed by BYU Baseball in 2020. As a result BYU Radio no longer streams those events on KBYU-HD 2. They were streamed on the BYU Sports Radio app and usually simulcast on ESPN 960 until BYU entered the Big 12. Once BYU entered the Big 12 women's soccer radio brpadcasts were dropped, but women's basketball games were added. The streaming platform was also moved from the BYU Sports Radio app to byuradio.org. ==Boosters==
