KHWA broadcasts to the Siskiyou County and Redding markets, and has one of the largest geographical reaches of any FM station Northern California.
It was later purchased in 1984 by Tom Erickson of Lake Havasu City, Arizona, moved to Mount Shasta and renamed KWHO.
On August 1, 2009, Jamison-Wolf entered into an LMA (Local Marketing Agreement) with TRC Enterprises, LLC, a company owned and operated by long-time morning show host and Program Director Rick Martin.
Martin sold the station and translators K257CA and K269AT to Buffalo Broadcasting, LLC, owned by Mark and Cindy Baird, and on July 24, 2012, KCWH went silent (off the air).
Effective July 19, 2022, KHWA was officially purchased by Southern Oregon University and began broadcasting programming from Jefferson Public Radio.
KHWA's signal is transmitted up and down the Interstate 5 corridor from Weed to Orland at 102.3, to Yreka at 101.7, and locally in Mount Shasta at 99.3, all on the FM band.
KHWA was a longtime affiliate of the Oakland A's, and was the flagship station for Mount Shasta High School football with Rick Martin and the late Al Blackmore.
