[Elecraft] [KX3] Overheating when portable

[Phil Wheeler]

A non air flow thought I had: I wonder if adding 
external finned heat sinks under the two bolts 
holding the PA transistors to the existing heat 
sink would have any appreciable effect. The other 
thought I've had is putting some heat sink 
compound, like Arctic Silver 5, between those 
transistors and the panel they mount to, in order 
to improve heat conduction (though it seems 
Elecraft would have included this in be build if 
beneficial).
