The extended Temp Compensation will not help with a hi temperature problem.
What it will do is reduce the frequency drift over a wide frequency
range - so for maintaining frequency stability while the KX3 is heating
up, yes that stability will be increased. The temperature problem with
extended transmit 'key down' times is what is causing the heating.
Cooling the PA transistors or reducing the power is is the only way to
reduce the effects of high temperature.
The new heatsink will help, lowering the power will help, a fan blowing
on the heatsink will help, an aftermarket heatsink will help. Anything
to keep the PA transistors cooler.

Ron, I don't have a KX3, but from what I can recall, everyone who has ran that" Temp
Compensation deal " has been very satisfied and said that it helps .
Maybe someone who has done the compensation could comment .
