During its days as a separately programmed PBS station, WVPT was the smallest PBS station licensed to Virginia. It primarily serves 22 counties and independent cities in Virginia and nine counties in West Virginia, one of the largest coverage areas in the PBS system. Much of this area is very mountainous. Largely because most of its service area is located in the United States National Radio Quiet Zone, its two main transmitters operated at only 525,000 watts and 141,000 watts in analog—in both cases, fairly modest for a full PBS member on the UHF band. Even in digital, they are not nearly strong enough to cover this vast and rugged area. This is despite WVPT's digital channel being located on VHF; normally VHF signals "bend" over rugged terrain better than UHF signals.
