KCSN is an FM radio station licensed to Northridge, Los Angeles, California, and a service of California State University, Northridge. Broadcasting at 88.5 MHz, KCSN previously featured classical music, AAA (Adult Album Alternative) and Americana music, and in-house news broadcasts by the CSUN broadcast journalism students. However, on March 1, KCSN moved all classical music from its primary FM signal to its HD2 channel. The main FM (HD1) channel was switched to an all-AAA programming format without news.
The only remaining live on-air personalities on KCSN's main FM signal are volunteers who broadcast specialty programming on weekends. On June 1, 2011, the station announced the arrival of new program director, Sky Daniels, who programmed KMET during the final days before it went off the air. Three new DJs were introduced on July 15, 2011. They are: Jim Nelson (Monday to Saturday mornings), Meishel (weekday middays) and Sky Daniels (weekday afternoons). On July 16, 2011, KCSN became the new radio home of Nic Harcourt (formerly of KCRW) and his new radio program, Connections with Nic Harcourt, which airs Saturday afternoons from 3pm to 6pm. In October 2012, Harcourt began hosting the morning show.
Students produce six minute morning news segments that air at 6:30am and 7:30am and three minute segments at 7am and 8am. A nightly half hour news program called the "Evening Update" airs at 6pm. These news programs are heard only on the secondary HD2 channel.
KCSN's studios are located in the Valley Performing Arts Center on the CSUN campus. The station can be heard across the San Fernando Valley, the Santa Clarita Valley and via a booster, in the West Los Angeles area.
