KXST (CBS Sports Radio AM 1140) 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 CBS Radio. The station's studios are located in the unincorporated Clark County area of Spring Valley, while its transmitter is near Nellis Air Force Base.
1140 AM was known as KRSR "The Krusher", a heavy metal-formatted station in the 1980s, whose DJ is a robotic voice similar to that of the Cylon voice used on Battlestar Galactica.
Before that, 1140 used the call letters KMJJ and was known as Magic 11 through the 80s. The station ran a unique format, with voice tracks from major market air talent, and an uptempo mix of oldies and current songs. Air talent included Charlie & Harrigan, Kelly & Kline, Steve Goddard, Rick Shaw, Bobby Ocean, and Wolfman Jack. The station was at one time the flagship for UNLV football and basketball. In 1989, 1140 AM began simulcasting 98.5 FM KLUC until 1993.
In 1993, 1140 became KXNO "Casino Radio". It was mostly tourist information. In 1997, KXNO switched to KSFN "Sports 1140" for two years from 1997 to 1999 (during which the station acted as a flagship for Frank Andrews's and Papa Joe Chevalier's national shows on the Sports Fan Radio Network).
In 1999, KSFN became "Cruisin' Oldies." The station was then mostly "jockless", and played oldies from the late 1950s to early 1960s. This format lasted until 2001.
KSFN then became "Hot Talk 1140" in 2001. Talk shows consisted of Tom Leykis, Phil Hendrie, Opie & Anthony, etc. In 2005, KSFN became "Spike 1140" radio for men (in reference to co-owned Spike TV). While the format still remained the same, sports programs were mixed in. Dodgers baseball could then be heard on 1140. In 2005, the station gained a webcast, enabling a world wide audience.
On April 14, 2008, KSFN returned to an all all-sports format, 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 call letters changed to KYDZ and the station took a children geared format. The format switch was under the direction of Cat Thomas, director of programing at CBS Radio, and KLUC imaging director John James. The station was automated throughout its entire run, but featured children on air personalities at live events. It was one of the few children's radio stations in the United States that was not affiliated with Radio Disney.
