WYPM (93.3 FM) is a non-commercial, public FM radio station that is licensed to serve Chambersburg, Pennsylvania. The station is owned by WITF, Inc., and simulcasts the NPR talk and news programming of WITF-FM in Harrisburg.

The Federal Communications Commission granted The Tower Realty Company a construction permit for the station on August 18, 1948, awarding it the WCUM-FM call sign. The new station was assigned to 102.9 MHz in Cumberland, Maryland. The FCC granted the station the authority to begin broadcasting starting on October 20, 1948, followed by its first license on November 2, 1951.^[2]

The station was sold several times between the late 1950s and the late 1970s. The first sale was made from The Tower Realty Company to Allegany County Broadcasting Corporation, effective April 1, 1959, then to Group "B" Broadcasting Company, Inc., effective July 1, 1965, then to WCUM, Inc., effective May 1, 1968, then to WCUM Radio, Inc., effective October 31, 1974, and then to Greater Cumberland Radio Broadcasting, Inc., effective August 19, 1977.
