 WGGO's licensed 5,000-watt daytime signal, the strongest AM signal in southwestern New York, covers all of Cattaraugus County and much of Chautauqua, Allegany, and McKean Counties as well as the Southtowns of Erie County.Further north, an FCC oversight means that WRSB's signal begins interfering with WGGO's near Buffalo.WGGO signed on June 19, 1957 under the guidance of religious broadcaster George Thayer as WNYS, although they changed their call signs fairly early in their existence.
