WGYM (1580 kHz) is a non-commercial AM radio station broadcasting a religious format aimed at Catholic listeners. The station is licensed to Hammonton, New Jersey, and serves parts of Atlantic County and Camden County. The station is owned by the Domestic Church Media Foundation, which also owns three other stations, also in New Jersey: WFJS in Trenton, WFJS-FM in Freehold, and WSMJ in North Wildwood. All four broadcast Catholic programming, mostly supplied by the EWTN Radio Network. WGYM operates at 1,000 watts by day from a transmitter located off Grand Street South. Because AM 1580 is a clear channel frequency reserved for Canada, WGYM must reduce power to 6 watts at night, when AM radio waves travel farther. ()
