WQHS is the only wholly student-operated college radio station at the University of Pennsylvania. WXPN was the University's principal student radio station until 1975, with WQHS as an AM-based training ground for DJs. After 1975, WQHS became the official student radio station of the University, with WXPN being taken over by an external company. The radio station currently broadcasts an eclectic freeform radio format over internet radio, as a result of their radio tower, formerly on top of Harnwell College House, falling down in a severe storm in 2003.
