I have been Director of Engineering at four different television
stations, had corporate responsibility for additional stations and
visited countless transmitter sites over 20+ years. In every case
where there the station had alternate/main and/or "back-up"
transmitters, the filaments were kept live so the back-up could
go on the air instantly.
