According to the article, Maine Public Broadcasting (MPBN) is doing some cost cutting. They will shut down their radio transmitter in Fort Kent and the TV transmitter in Calais by the New Brunswick border. No mention as to whether they meant both analog and digital for WMED-TV/DT. I'm going to guess both of them here.
