I think I misspoke. The station had a 40kW ERP, but the transmitter put
out right at 20kW.

Yes it would take a lot of power to leak out of a dummy load and
exceed the ham limit. I recall working with a load on a 50 kw TV
transmitter. It had dowtherm circulated over an element about a foot
long and an inch in diameter. It was a five horse pump and there was a
heat exchanger to the house water supply., That one was good for CCS.

I was told there would be no math on this reflector, but 30db is
1000 times, so 1.5 MW That would take one heck of a dummy load.
Not that I imagine that I've seen everything, but the biggest
dummy load I've ever seen was able to handle 40 kW of 100 MHz
signal for brief periods with the coolant circulating.
I think someone's mistaken though. Hams don't have radiated power
limits above 1.5 MHz.

well if the leakage from a dummy load is 30 db down how much power
would you need to be 30 db above 1500 watt?

Does the the permitted radiated power limit for hams apply to
dummy loads?

Hamfest is pretty good so far. I did notice on the
Expert Amplifier video that they demo'd the 1.5K amp into
a dummy load, of course, and they got 1500 watts out on 30
meters (10 MHz).
1500 on 30 ???? Not sure they knew what they were doing.
