But, to get back to the real thread, Don, KYV, said it about as clear as
you can get it:
"Run a certain plate voltage and load the transmitter enough that plate
voltage multiplied by plate current calculates to 1000 watts. Carefully
watch the scope so that the negative modulation peaks just barely
approach
baseline, and make sure the positive peaks do not show evidence of
flat-topping. Simple laws of physics"
It's not rocket science.
Pete, wa2cwa
Patrick was speaking of legalities. I'm sure all of us here, know how
to load a rig to a kW.
What he's asking is:
How do we go about getting our old '1kW DC Input to the final' rating
back from the Feds?
And, as noble as that sounds, I'm afraid that you'd have a better chance
of picking up a 250TH
at your local corner store market. You know, the one that has a
tube-tester in it?
Just like those days of tube testers in the local stores, so too are the
days of running a legal 1kW
DC input power level gone.
