KUSC (91.5 MHz FM) is a listener-supported classical music radio station broadcasting from downtown Los Angeles, California, USA. KUSC is owned and operated by the University of Southern California, which also operates student-run Internet station KXSC (AM) and San Francisco's classical station KDFC. It is the largest non-profit classical music station in the country and the only classical radio station in the Greater Los Angeles Area. In February 2014, public radio station KCRW of Santa Monica announced that it would buy the Santa Barbara Foundation's classical station KDB (FM) 93.7 in Santa Barbara for $1 million. The transaction will allow KCRW to begin using KQSC, USC's current repeater station in Santa Barbara, as a repeater for KCRW's programming, while transferring KUSC's classical programming from KQSC to KDB, thus perpetuating KDB's role as Santa Barbara's classical station. The legacy KDB call letters have been retained.
Notable local programming includes Dennis Bartel's weekday morning show, Rich Capparela's weekday afternoon program, Jim Svejda's weekday evening show, Duff Murphy's Saturday opera show, and special features by Gail Eichenthal. Other announcers include Alan Chapman and Brian Lauritzen. Management helped establish the nationwide Classical 24 network and also supervised Virginia's WMRA network before taking up leadership at KUSC.
The station holds three membership drives annually to help support operational costs. These drives usually last less than ten days. Corporate sponsors include Lexus, Miramax Films, University of Redlands, Universal Music Group, City of Hope National Medical Center and Providence Health & Services.
