[Elecraft] Aftermarket KX3 heatsinks

[Dave Lankshear]

This looks very promising.  Thermal conductivity 5x that of copper.  A
couple of layers of this under the heatsink would provide an excellent
interface.

There is a small matter of the cost, but then, to some, it might be an
irrelevance Hi!

 

Incidentally, I'm more than happy with the KB8UHN heatsink and the service
received from John.  Key down for half an hour into a dummy load, 14v
external PSU, no problem at all and its low profile makes it look "the biz."
