In 1965, WRAF's General Manager proposed moving the station to the FM band, which was still largely unused. In November of that year, the FCC approved the construction of an educational station at the frequency 90.5 MHz (the frequency the station itself requested). The station's first antenna was atop a pole located behind the Student Center. The FCC approved the station's request for "WHRW" as the new station's call letters. "HRW" was chosen to represent "Harpur Radio Workshop." While stereo FM had been introduced in the early 1960s, it was not an inexpensive technology, and WHRW's first transmitter was a humble 10 watts, in mono.
