[Elecraft] KX3 heatsink question

[Howard Hoyt]

Hi Rich,

The advantages of a real aftermarket heatsink (not the poorly designed 
imports) is rapid thermal recovery after each transmit cycle and less 
heat re-radiated into the rig.  The import with the rounded fin root as 
well as others have a less optimum volume to surface area ratio and stay 
much hotter between transmit cycles. Also a good heatsink will allow 
higher power operation in temperatures we sometimes find ourselves when 
operating on picnic tables and the like in the summer!

(commercial content) We find most of our customers who are occasional 
digital users are satisfied with the smaller of our two heatsinks, model 
Kx31, but the JT mode enthusiasts, especially contesters are going for 
the slightly larger Kx32 model.  Much more info on our website.  Just 
our experience...YMMV
