Clifford, Michael:

So you're saying modern ATSC transmitters
actually use less power then the old NTs?



The heaters in Klystons used a lot of power, that had to be removed as
heat, in a water chiller. One 25 KW UHF transmitter that I rebuilt used
a pair of 1.5V, 1000A heaters per tube. That was 3 KW, then the fan on
the water chiller was a 480V, three phase, 5 hp motor. The circulating
pump was anther two HP. None of this ended up at the output port.
