KCBS-FM is a radio station in Los Angeles, California broadcasting to the Greater Los Angeles area on 93.1 FM. KCBS-FM airs an adult hits music format branded as "Jack-FM".
Unlike other radio stations of similar format, the Los Angeles Jack FM playlist runs a fairly focused playlist of popular classic rock and Alternative Rock tracks. Currently, the station has no air staff save for Tami Heide with her "Jacktivities" (events and whatever announcements deemed worthy by "jack"). Unlike most other stations in this format, the call sign no longer includes any form of the word "Jack," opting instead to hold over calls from a previous format. This is similar to its FM sister station in New York, WCBS-FM, which had maintained its WCBS calls during its run as "Jack FM."
Although Jack proclaims that the station is run "in a dumpy little building in beautiful downtown Culver City", KCBS-FM is actually at the intersection of Venice Boulevard and Fairfax Avenue in Los Angeles, about ½ mile north of Culver City. The station's transmitter is based on Mount Wilson.
