[2] 1320 AM began life as the original KBLU, signing on September 6, 1959.

When Eller Telecasting and Combined Communications merged in 1969, the newly formed group had to divest one of KBLU or KYUM at 560, choosing to keep the latter and donate the former to Arizona Western College.

Arizona Western College immediately relocated the transmitter to its campus and instituted a public radio format, which signed on for the first time on July 11, 1970.

In 2009, the K-Jazz Radio Network with its transmitters in northwestern and northern Arizona entered into agreement with Colorado River Public Media, by which those transmitters simulcast 1320 AM on weekdays.

The station changed its callsign to the current KOFA on July 13, 2017.
