KHSU-FM (90.5 FM) is an NPR-member radio station, licensed to Arcata, California, USA. The station is currently owned by Humboldt State University. KHSU provides the region encompassing Humboldt and Del Norte Counties in California as well as portions of Trinity and Mendocino Counties in California and Curry County in Oregon, with news information and entertainment from public radio producers like National Public Radio (NPR), Public Radio International (PRI), American Public Media (APM) and the BBC. The station began as a radio classroom experiment in the 1930s and 1940s on the campus of Humboldt State College. In October 1960 KHSC became the first non-commercial station licensed on a California college or university campus. KHSC later changed its call letters to KHSU when the Humboldt State College became Humboldt State University.
