On May 20, 1965, Dale A. Owens filed a construction permit for a new daytime-only station to broadcast with 1,000 watts on 1280 kHz at Fortuna, which the Federal Communications Commission (FCC) granted on April 20, 1966.
[7] KAJK-AM-FM, having since shifted to adult contemporary, was sold for $450,000 by Keith Allgood to Miller Broadcasting Company in 1998.
[2] Under Del Rosario Talpa's ownership, the station—airing a Spanish-language format known as "La Nueva 1090"—financially struggled and faced several regulatory issues.
In 2005, KNCR was evicted on short notice from its longtime tower site and moved transmission to studios at Smith Lane without filing for an authorization to do so; this resulted in a $3,200 fine being assessed in 2007.
[11] The station went silent on December 1, 2020, with the application for special temporary authority noting "lost tower site and financial hardship".
