[Elecraft] KPA1500 Thermal problems

[Andy Durbin]

"I rode the drive power downward as the power increased to stay below the trip point of 105c."

Was that intended to be "as the temperature increased"?  If so, do you have any data that shows PA dissipation is lower at reduced power levels for the KPA1500?  For the KPA500 PA dissipation increases as power is reduced and peaks at about half rated output.
