KUAZ is a radio station operated out of The University of Arizona that serves the Tucson, Arizona, metropolitan area. It operates on 1550 on the AM dial (during the daytime) and 89.1 on the FM dial with a combination of news and National Public Radio format during the day and jazz in the evenings.

A translator, K217GI, relays KUAZ to Sierra Vista on 91.3 MHz.


1550 AM in Tucson began as KSWC, but changed its calls to KFIF before signing on. It was owned by the Southwest Broadcasting Corporation.

In 1967, John B. Walton, who had bought KFIF in 1965, obtained the license for a new station at 580 AM, KIKX. The new station on 580 could operate 24 hours a day. 1550 AM was donated to the University of Arizona and became KUAT on July 1, 1967. KUAT initially held a format of classical and jazz music, going all-jazz when KUAT-FM was built in 1975.

The U of A put 89.1 FM on the air in 1991. The AM station adopted the KUAZ calls on August 11, 2000; the same day, the FM station became KUAZ-FM.
