WFCN
WFCN is an AM radio station broadcasting at 1200 kHz. Licensed to Nashville, Tennessee, it airs a Christian radio format. WFCN is owned by the Chicago-based Moody Bible Institute and it simulcasts its sister station in nearby Murfreesboro, Tennessee, 91.7 WFCM-FM. Programming on WFCN is rebroadcast on FM translator 98.7 W254CK.
WFCN operates at 10,000 by day but because 1200 AM is a clear channel frequency, WFCN must sign-off the air at night to protect Class A station WOAI in San Antonio. The FM translator is permitted to operate 24 hours a day.
