Oroville Radio, Incorporated, filed with theFederal Communications Commission (FCC) on June 25, 1976, to build a new FM radio station inOroville on 97.7 Mhz. The FCC approved the application on March 15, 1977; the station permit bore the call sign KFAM before Vernon Uecker acquired majority control later in the year. The call letters were changed to KEWE before the station began broadcasting on July 6, 1979.^[2][3] It aired abig band music format;^[3] Uecker selected big band because he wanted a more active format than thebeautiful music then in vogue, which he termed "background music"; a format he "didn't want to do".^[4] The class A station was approved to change to a class B1 outlet by the FCC in 1991.^[5]

In 1996, a 71-year-old Uecker announced he was retiring and soldKORV (1340 AM) and KEWE to Z-Spanish Radio Holdings, the highest bidder for the station. On April 1, Z-Spanish took over operation of KEWE. It changed the call letters to KZCO and began programmingRegional Mexican music,^[6] using its satellite-delivered Z Hot Hits programming.^[7] Some upset listeners commented that the format flip was a sign of the times; one told theParadise Post, "We are being invaded" by Hispanics.^[8] A group later bought back KORV to relaunch it as KEWE with big band music in 1998.^[4] Z-Spanish changed the call sign from KZCO to KHHZ on March 10, 2000.^[9]

In April 2000, Z-Spanish was purchased byEntravision Communications.^[10] Entravision then sold the Chico station toClear Channel Communications, which relaunched it as KHHZ "Radio México, La Gran X" and increased the station's local content.^[11] Clear Channel then sold its entire Chico cluster in 2004 to Deer Creek Broadcasting, controlled by Elliot Evers, for $5.1 million.^[12] The station's city of license was changed from Oroville to Gridley in 2008 to allowKMJE to change its city of license from Gridley toWoodland.^[13]

In 2019, Bustos acquired three stations in the market and proceeded to tradeKFMF 93.9 andKZAP 96.7 to Deer Creek in exchange for KHHZ. It then converted KHHZ to its La Gran D format.^[14]
