KXNT-FM is a commercial radio station located in Henderson, Nevada, broadcasting in the Las Vegas, Nevada area on 100.5 FM. KXNT-FM airs a news/talk format, simulcasting KXNT.
KXNT-FM began in 1982 with the call letters KMZQ. KMZQ went through many changes over its 12 year run. KMZQ was known as "Q-100" and "Klassy 100." From 1995 to 2005, it has been known as Lite 100.5 FM. The first on-air personality was Ron Kirsh. Ron is still heard on the Las Vegas airwaves on KJUL.
On June 24, 2005, at 2 PM, after playing "Leaving Las Vegas" by Sheryl Crow, KMZQ began stunting with Christmas music; 45 minutes later, the stunt shifted to movie theme songs. At 3, Lite 100.5 became Jack FM, with a variety hits format. The first song on "Jack" was "No Such Thing" by John Mayer. Shortly thereafter, the call letters were changed to KKJJ. KMZQ-FM's call letters now belong to FM 99.3 in Payson, Arizona. However, KMZQ-AM airs on AM-670 in Las Vegas, which is a simulcast of KMZQ-FM in Payson.
CBS Radio has announced that starting August 16, 2010, Jack FM would be replaced with a simulcast of sister station KXNT, and would be known as "100.5 FM Newsradio KXNT". At 5 a.m., on August 16, after playing the Talk Talk song "Talk Talk", referring to the news/talk format, the KXNT Legal ID kicked in, officially ending Jack FM in Las Vegas and starting KXNT on FM Radio.
Currently, mornings include The Wall Street Journal Report followed by the KXNT Morning News, with host Joe Gillespe and news anchor/sidekick Kristen Flowers. Corey Olson reports from the field, with reporters Mark Thomas and Brian Shaprio, and afternoon news anchor Robert Rytina also contributing.
The KXNT lineup also includes syndicated Rush Limbaugh, Sean Hannity, Dave Ramsey, Mark Levin, and Coast to Coast AM.
