WJFF (''90.5 WJFF'') is a public radio station broadcasting at 90.5 MHz, licensed to Jeffersonville, New York and transmits from a tower approximately two miles west of Liberty, New York〔(【引用サイトリンク】title=WJFF Facility Record )〕 It is perhaps the nation's only hydropowered radio station. The power for the station's studios and offices are drawn from a dam 50 feet away adjacent to Lake Jefferson.〔(【引用サイトリンク】title=Hydropowered Radio Story )〕 ==History== In 1984, Malcolm Brown purchased the Lake Jefferson dam () and power house and began to repair the hydro plant which was originally constructed in 1927. In 1986, the hydro plant was placed in service, generating enough power to supply 20-25 area homes. In January 1988, Catskill Radio, Inc., also owned by Malcolm Brown, received a Construction Permit for WJFF. The radio station's studio building was built on the north side of the Jefferson Lake dam, about 50 feet away from the generator house. The station was completed by mostly volunteer labor, signing on for the first time on January 20, 1990. Initially the station transmitted with a power of 830 watts, this was increased to 3,700 watts in early 1996.〔(【引用サイトリンク】title=WJFF Application Search Results )〕 1996 was also the year that Catskill Radio Inc. applied for and received authorization to build its Monticello, NY translator, W233AH.〔(【引用サイトリンク】title=W233AH Facility Record )〕 Since 2000, the Lake Jefferson Dam has survived numerous severe floods and still provides all of the power to run WJFF with the excess being sold to NYSEG, the local power company. In 2005, the dam and generating equipment were sold to Kevin and Barbra Gref, who continue to operate it. The transmitter site is located on a hill approximately six miles east of the studios and is powered conventionally by commercial electrical service. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WJFF」の詳細全文を読む スポンサード リンク
