KJIM AM 870 (now KFJZ) purchased the KFMF construction permit and it signed on the air on April 10, 1962 as KJIM-FM. At first, KJIM-FM simulcast the daytime-only AM sister station, to allow programming to be heard after sunset. Later, KJIM-FM switched to an automated easy listening instrumental format. KJIM-AM-FM acquired a UHF-TV permit in the mid-1960s to construct Channel 21 (today KTXA-TV). The company sold off AM 870 to raise capital.
