 Tests by Pennsylvania State University public educational WPSX-TV (now WPSU-TV) were initially made in 2003 WPSU was in analog a VHF 3 station which serves State College, Pennsylvania from a distant transmitter which must also cover Johnstown and Altoona.As a digital station, WPSU had used a large UHF 15 transmitter at the location of the original low-VHF broadcast tower, leading to localised problems with terrain shielding which interfered with UHF reception in State College itself.Relocation of the main transmitter would have interfered with the station's ability to serve the other two communities.
