Guys, it's called "headroom". No sense beating an Amp to death if you can run one at half-power. Now lets me think, back in the day weren't those amps called "California Kilowatts" ?? 73, Dick, W1KSZ

There's a lot of banter going back and forth, but mostly just posturing. A few hard facts, with science to back it up, would be more instructive to the group. But then, I belong to the school of Alch

As far as the Power Supply goes, there are still a lot of server supplies out there that deliver ~ 50 vdc @ ~ 50 Amps. Put a pair in series and you have some serious power. 73, Dick, W1KSZ __________

There are, today, commercial KW VHF and kits for VHF and UHF KW on 2, 220 and 432 using LDMOS devices. Cooling them does not seem to be a problem. Maybe the day of using 6 or more devices is past. 73
