It broadcast from a transmitter on the Hanover Township Municipal Building[1] with 10 watts on 90.3 MHz, making it a Class D station.
[3] When it signed on, WHPH broadcast for just over two hours a day on weekdays during the school year—from 7:30 a.m. to 8:15 a.m. and again between 4 p.m. and 5:30 p.m.[1] The FCC approved an additional station on 90.3 in 1973.
That station, WMSC at Montclair State College, would cause some interference in the outer portions of the WHPH coverage area.
Hanover Park fought with Montclair State over the viability of a new co-channel station; East Hanover Township went as far to file a petition to deny on WMSC's application for a new station, while Montclair State pointed to engineering studies that reported that the new WMSC would not create core interference to WHPH.
[15] Despite warnings that closing WHPH would be an irrevocable act because of the unavailability of FM station space in the region,[16] and proposals from parents to raise funds, the board of education voted against allocating $26,000 for an adviser's salary in June and WHPH was signed off for good on June 13, 1986.
