KSAK is the FM campus radio station of the Mt. San Antonio College at Walnut, California. The station broadcasts a professionally programmed format designed to represent what actually goes on in the radio industry, instead of the alternative programming typically found on most college radio stations. Broadcasters and producers from local commercial radio stations teach classes at the college and supervise students who produce and announce news and music programming. The station broadcasts music in alternating blocks of hip-hop, alternative rock, and pop music, interspersed with news and public service announcements.
