KXST is a radio station licensed to North Las Vegas, Nevada, broadcasting to the Las Vegas, Nevada area on 1140 AM. The station is owned by Entercom, and broadcasts a sports talk format as part of the CBS Sports Radio network. The station's studios are located in the unincorporated Clark County area of Spring Valley, while its transmitter is near Nellis Air Force Base.

KXST (AM 1140) is not licensed by the FCC to broadcast in the HD (digital) format.[1] KXST can also be heard on 107.5 FM HD3 (KXTE).


In the past, KXST ran a variety of formats, including adult contemporary in the 1970s and mid-1980s as KMJJ, heavy metal The Crusher from 1987 to 1990, and then an AM simulcast of KLUC. In 1993, the station switched to a tourist information service branded as KXNO Casino Radio, which carried a loop of advertising for shows occurring in the city.[2] In 1996, the station was acquired by American Radio Systems, and flipped to sports talk radio as KSFN The Fan, featuring play-by-play of UNLV Rebels college basketball, the Arizona Diamondbacks, and the Oakland Raiders. The format was low-rated, and the station failed to register on Arbitron ratings.[2] In 1999, KSFN flipped to an oldies format branded as Crusin' Oldies, with a focus on music from the late-1950s and early 1960s, targeted primarily to the region's baby boomer demographic.[2]

In 2001, KSFN flipped to talk radio as Hot Talk 1140, with a lineup featuring programs such as Tom Leykis, Phil Hendrie, and Opie & Anthony. In January 2005, the station re-branded as Spike 1140 AM, a brand extension of the then co-owned, male-oriented cable channel Spike. The station added sports programming, including an affiliation with Sporting News Radio.[3]

On April 14, 2008, KSFN returned to an all-sports format,[4] dropping Leykis, and not picking up the Mike O'Meara Show after the retirement of Don Geronimo from the Don and Mike Show. At the same time, the station added Dan Patrick and expanded programming from Sporting News Radio while retaining Opie & Anthony and the Dodgers. The new format also included local personalities Casey Freelove and Corey Olson hosting "Freelove and Olson" weeknights 7-9pm and Saturdays 1-4pm until November 2008. The station also aired programming from Sporting News Radio. Beginning in August 2008, KSFN also gained the rights to be the official station for USC Trojans football in Las Vegas and the carrier of the Sports USA Radio Network NFL doubleheader.

On March 2, 2009, the station changed its call letters to KYDZ and flipped to a children's radio format branded as Kydz Radio, focusing on teen pop and other songs oriented towards tweens.[5] On January 2, 2013, KYDZ returned to sports talk as an owned-and-operated outlet of the newly established CBS Sports Radio network.[6]

On February 2, 2017, CBS Radio announced it would merge with Entercom.[7] The merger was approved on November 9, 2017, and was consummated on the 17th.[8][9]

In August 2017, a reporter from CBS television affiliate KLAS-TV obtained an internal e-mail that instructed all of CBS's radio stations in Las Vegas, including KXST, to not cover or otherwise acknowledge the city's new National Hockey League team, the Vegas Golden Knights, on any platform, in retaliation for having been outbid by competitor KRLV for rights to be the team's flagship radio station. Following the reports, CBS Radio Las Vegas senior vice president Tony Perlongo apologized to the team and told the Washington Post that he had reversed the policy, stating that it was an "error in judgement on our part", and that CBS Radio would "cover the team, first and foremost on Sports Radio 1140 and on our music and news/talk stations as it makes sense for those formats and audiences."[10]
