In January 1988, Radio Catskill, Inc., received a construction permit for WJFF. The radio station's studio building was built on the north side of the Jefferson Lake dam. Spearheaded by Malcolm Brown and the enthusiasm of local residents, the station was constructed almost entirely by volunteer labor.
The station signed on January 20, 1990. Initially the station transmitted with a power of 830 watts. This was increased to 3,700 watts in early 1996.[2]
1996 was also the year that Catskill Radio Inc. applied for and received authorization to build its former Monticello FM translator, 94.5 W233AH.[3] Radio Catskill sold the translator effective November 8, 2023.
