WVSG (820 kHz, "St. Gabriel Radio") is a non-commercial AM radio station in Columbus, Ohio. It airs local Catholic talk programming in addition to the EWTN Global Catholic Radio Network. WVSG's schedule is simulcast on WSGR, 88.3 FM in New Boston, Ohio. WVSG broadcasts with 6,500 watts non-directional in the daytime, offering secondary coverage to almost half of Ohio, as far west as Dayton and the outer suburbs of Cincinnati and as far north as the outer suburbs of Toledo. But 820 AM is a clear channel frequency. So at night, a six-tower array is used in a directional pattern to protect the signal of Class A WBAP Fort Worth. WVSG's transmitter is off Red Rock Boulevard in Columbus. History Ohio State University The station was originally owned by Ohio State University, the oldest radio station in Columbus.
