Adult Contemporary, USA
KOST is a commercial FM radio station in Los Angeles, California. Owned by iHeartMedia, it broadcasts an adult contemporary radio format, switching to Christmas music for much of November and December. Its studios are co-located with its sister stations on West Olive Avenue in Burbank. KOST is the home of Ellen K, segments of whose morning show are syndicated to other iHeart AC stations on Saturday mornings.
The transmitter is atop Mount Wilson alongside most L.A. based television and FM radio stations. Those FM stations, along with KOST, are considered "superpower" grandfathered stations, since their effective radiated power (ERP) greatly exceeds the level set by the Federal Communications Commission for Class B FM stations at their height on Mount Wilson. KOST broadcasts using HD Radio technology.[2] The HD-2 digital subchannel rebroadcasts co-owned talk radio station KFI 640 AM. The HD-3 subchannel carries the iHeart soft adult contemporary format, "The Breeze."
