[Elecraft] KX3 heatsink question

[Jerry]

I bought a ProAudio heatsink for my KX# about 3 or 4 years ago and found
that since I could read and handle some relatively simple hand tools,
assembly was easy and straight forth. Using RTTY at full power, it got only
warm - made a nice ham warmer in the colder mountain areas. The price you
pay for ProAudio is well worth it.

Best regards,

Jerry, W1IE

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
