Aren't one or two VHF band stations in each market the "lighthouse" stations they maintained for civil defense/emergency communications use by analog TV? I'm talking ATSC 1.0 transition here.
One of our stations still has their analog NTSC/MTS transmitter. They transmit from the exciter (not final) into a dummy load for testing, but it's ready 24/7 to go back on the air should it be needed.
