[Elecraft] QRO - KPA500 Failure

[Andy Durbin]

"Basically, based on Bob's measurements, the power dissipated is fairly independent of drive level. So, running at reduced power really isn't stressing anything any more that full output."

I have done quite extensive testing of my KPA500 and provided links to my results.  My KPA500 PA dissipation is strongly dependent on the PA load but, for any given load, the peak dissipation is at out half power output.
