K-Love (1986-1988)

KLVV began broadcasting in Las Vegas on the 107.5 frequency in April 1986. It was an adult contemporary station calling itself "K-Love." (It was not connected with the current day Christian Contemporary network known as K-Love.)

Oldies 108 (1988-1992)

In November 1988, the station, now owned by EZ Communications, became KUDA, "Oldies 108 FM." Norm N. Nite once had a show on the station, called Solid Gold Scrapbook. In 1989, KUDA was purchased by Americom Broadcasting, which owned stations in Reno and Fresno.

KFBI (1992-1996)

Americom, headed by Tom Quinn, added Howard Stern’s show to the station in 1992, changed the station's call letters to KFBI and transitioned from oldies to classic rock in 1993. This was the first time Stern agreed to appear on a station outside of a top-10 radio market, and KFBI immediately surged to the top of ratings in Las Vegas, making KFBI the city's dominant radio station.

Alternative rock (1996-2022)

Three years later, in April 1996, Americom sold KFBI to American Radio Systems (ARS), where PD Mike Stern and GM Alan Gray changed the call letters to KXTE, flipped the station's format to alternative rock, and rebranded the station as “X 107.5”.^[3] ARS later merged with Infinity Broadcasting (forerunner to CBS Radio).

Stern stayed on KXTE until the station pulled him in November 2005, a month before he left terrestrial radio for Sirius Satellite Radio. He was replaced by Adam Carolla, which began airing on January 3, 2006, and ended on February 20, 2009. Dave Farra and Jason Mahoney, hosts of The Dave and Mahoney Morning Show, returned to the Las Vegas airwaves to take over mornings on April 20, 2009. On August 3, 2015, it was announced that Dave and Mahoney would re-locate from Las Vegas to CBS Radio sister station KHMX in Houston.^[4] On January 15, 2017, it was announced that the show would return to KXTE starting February 6.^[5]

On February 2, 2017, CBS Radio announced it would merge with Entercom (now Audacy).^[6] The merger was approved on November 9, 2017, and was consummated on November 17.^[7][8]

On September 14, 2020, KXTE rebranded as Alt 107.5 as part of a nationwide expansion of networked programming and the Alt brand across Entercom's alternative stations. As part of this, KXTE program director and afternoon host Ross Mahoney was let go, while "Dave & Mahoney" remained in mornings and would be syndicated to San Diego sister station KBZT. In addition, KXTE would add KROQ Los Angeles host Nicole Alvarez for middays, KRBZ Kansas City's "Church of Lazlo" for afternoons, and WNYL New York's Kevan Kenney and Bryce Segall for nights and overnights, respectively.^[9][10] By mid-2022, the station had dropped most of the out of market programming and was being programmed locally again.

On October 6, 2022, it was announced that Audacy and Beasley Broadcast Group would swap a pair of stations in Las Vegas, with Audacy swapping ownership of KXTE to Beasley in exchange for KDWN and translator K268CS. The company stated that the syndicated Dave & Mahoney show, based at KXTE, will remain on the station upon the closure of the deal.^[11] Beasley would begin operating the station through a local marketing agreement on November 14, at which time the station dismissed the entirety of the airstaff and began running jockless with limited imaging outside of Dave & Mahoney.^[11]

Hot talk, return to alternative (2022-present)

On December 19, 2022, KXTE returned to its prior X107.5 branding with the new slogan "Xtreme Radio", and changed its weekday lineup to focus on hot talk programs; Dave & Mahoney remains the station's morning/flagship show, and would be joined by the syndicated Free Beer and Hot Wings Show in middays, and Dave & Chuck the Freak from sister station WRIF in Detroit (which airs live in early mornings, and is replayed in afternoon drive). Alternative rock would continue to be featured during overnights and weekends.^[12] The acquisition of the station by Beasley was consummated on December 22, 2022.

The hot talk format failed to impact the market, bottoming out with a 1.4 share of the Nielsen market ratings for June 2023. As such, on July 28, 2023, at 10 a.m. (dropping the hot talk format midway through the song "Somebody That I Used to Know" by Gotye), coinciding with the station's addition of former KXTE and KOMP host Carlota Gonzalez, the station shifted back completely to alternative rock still under the "X" brand, with the move being deemed a "music takeover" led by Gonzalez to "bring the X you know back". The new iteration of the format primarily focuses on 1990s/2000s classic alternative, with a lean toward harder rock. With the move, the station dropped "Free Beer and Hot Wings" from middays, but retains Dave and Chuck the Freak in late afternoons, as well as Beasley's syndicated "Cooper and Anthony" in evenings.^[13]

KXTE HD programming

• KXTE-HD2 signed on its HD Radio programming in 2001 with X2, a deep tracks alternative format, then in 2010, flipped to an all-80s format branded as "Rewind". On January 22, 2014, KXTE-HD2 flipped to dance radio, branded as "SIN 107.5".^[15][16] “SIN” would later be replaced with a classic hits format, branded as “DLC Radio” and sponsored full-time by short-term loan provider Dollar Loan Center.
