WXPK (107.1 MHz), branded as 107.1 The Peak, is a commercial FM radio station licensed to Briarcliff Manor, New York, and serving the northern suburbs of the New York metropolitan area. It is owned by Pamal Broadcasting and broadcasts an Adult Album Alternative (AAA) radio format. The radio studios are in White Plains and the transmitter tower is off the Sprain Brook Parkway at the Westchester County Correctional Facility in Valhalla. History On April 8, 1960, WRNW got its start at 454 Main Street in Mount Kisco playing a mixture of light classical music and easy listening songs. It began broadcasting in FM stereo in 1964. Founder and broadcast engineer Richard Burden was instrumental in the development of FM stereo broadcasting. By 1967, the station had moved to the second floor at 78 Lexington Avenue, and in June of that year, program director Don Bayley adopted an album rock format making WRNW one of the first FM stations in the New York City area to play rock music full time. (New York's WOR-FM went rock in 1966, but was hampered by an strike; WNEW-FM started its progressive rock format in October 1967.) In 1969, WRNW was sold to Lake Champlain Broadcasting Company, which also owned 105.9 WHBI in Newark. WRNW then played big band music during the day and sold brokered programming from 10 p.m.–2 a.m. weekdays and all day weekends to clients shared with WHBI. According to WRNW's founder, the call letters stood for "Wonderful Radio Northern Westchester." In 1971, WRNW changed to an easy listening format, and then to Top 40. In 1972, the station transitioned to a progressive rock format. On Monday, July 9, 1973, WRNW inaugurated transmissions from its new Briarcliff Manor studio on the second floor of a small house at 55 Woodside Avenue. The new transmitter was in Irvington, covering White Plains, Yonkers and other parts of Westchester and Rockland Counties. It was there, in 1976 that Howard Stern obtained his first full time paying radio job as a disc jockey and program director. Meg Griffin, later of WNEW-FM, WPIX-FM, WXRK and Sirius Satellite Radio, was also music director of the station during the mid-70s. Ted Utz also began his professional career at the station in 1976 and went on to program and manage pioneering stations like WMMR in Philadelphia and WNEW-FM.
