The station went on the air as KXEM on July 11, 2001 (on the same day, sister station KTKP became KXEG). On September 7, 2004, the station changed its call sign to the current KXXT, which was accompanied by a format change to Air America progressive talk radio under the name 1010 Talk. In October 2005, owner James Crystal Enterprises sold three stations, including KXXT and KXEG, to Communicom, which mostly owned stations with religious formats. The format change occurred on February 1, 2006; Air America programs would move to KPHX 1480 AM by the end of March.
In January 2011, after the attempted assassination of Arizona Representative Gabrielle Giffords (see 2011 Tucson shooting ), KXXT National Talk Show Host Steve Sanchez of The Steve Sanchez Show offered 30 minutes of airtime to Westboro Baptist Church in exchange for the Church agreeing not to protest at the funeral of 9 year old Christina Green who was killed during the assassination attempt.
