The permit initially called for WNBT to operate at a frequency of 1570 kHz and at a power of 250 watts, daytime only, from a transmitter facility upon Reservoir Hill overlooking downtown Wellsboro.
Farm and Home successfully applied in May 1955 for a frequency change from 1570 to 1490 kHz, and to add nighttime operation at a continuous output power of 250 watts.
In May 1957, Cary H. Simpson, owner of the Allegheny Mountain Network based in Tyrone, acquired positive control of the station through the sale of stock by shareholder Carl Green to Farm and Home Broadcasting Company.
In 1978, Farm and Home Broadcasting moved WNBT's studios to the location of its FM sister station's (known then as WGCR) transmitter facility off Route 660, co-located with the Tioga County Communications Fire Tower in Delmar Township, two miles west of Wellsboro.
In July 2016, Allegheny Mountain Network agreed to sell WNBT, sister stations WNBT-FM and WNBQ, and FM translator W225AT, for $400,000.
