History

KNXN originated with a 1978 application to build a new station on 1470 kHz in Sierra Vista. It was granted a construction permit the next year.^[3]

The station was assigned the call letters KSVA on March 31, 1980. It officially signed on the air on June 20, 1980; 45 years ago (June 20, 1980).^[4]

The call sign changed to KMFI on August 1, 1987, and to KNXN on November 8, 1993.^[5]
