What KALX Radio 90.7 FM Berkeley does

KALX Radio 90.7 FM Berkeley is a non-profit, listener-supported community radio station operated by the Regents of the University of California on behalf of UC Berkeley. Founded in 1962 as KAL and rebranded to KALX in 1968, the station broadcasts from Barrows Hall on a freeform format at 90.7 FM, reaching the San Francisco Bay Area. Programming spans diverse music genres, news, sports (including Cal Berkeley football broadcasts and the Bear Talk show), and public affairs content, all curated by volunteer DJs who are UC Berkeley students and community members. The station maintains a music library exceeding 100,000 records and offers additional content products including live in-studio concerts (KALX Live), specialty music charts, weekly entertainment calendars, and concert reviews.

KALX's core technology consists of an FCC-licensed FM transmission at 90.7 FM paired with HTML5-based live internet streaming accessible via its website. Beyond terrestrial broadcast, the station distributes content globally through podcast syndication (iTunes), a YouTube channel, and a blog platform (KALXtra) covering reviews, interviews, announcements, and event listings. Its podcast portfolio includes Berkeley Brainwaves (campus stories), Fiat Lux Redux (edited UC Berkeley lectures), The Graduates (graduate student research), and Spaced Out (community/social topics), extending the station's reach beyond the Bay Area into on-demand audio.

KALX operates under a donation-based revenue model with no commercial advertising, sponsorships, or paid products; funding is sourced from listener contributions and institutional support from UC Berkeley. The station does not have external investors, venture capital, or paying customers in the traditional sense, and no financial figures are publicly disclosed. Its customer base is distributed across UC Berkeley students, Bay Area community listeners, and independent artists seeking airplay, served through a horizontal segmentation approach with no concentration in any single segment.
