Ed,
The KX3 "wrap-under" heatsink is adequate for most modes. However if
you are using data modes with long transmit periods at power levels
above 7 or 8 watts, you might want to consider an aftermarket heatsink.
Give it a try and feel the heatsink after several transmission periods.
It will be warm, but you should be able to hold your hand on the
heatsink without discomfort. That is always a good test for OK vs. Too Hot.

With some expert help from the Elecraft forum, I'm up and running JT65/9 using
my new KX3.....
My rig's s/n is 9403, do I still need to consider upgrading to the after-market
heatsink or the one that came with my new KX3 (9403) sufficient for most data
modes?
