[Elecraft] KX3 heatsink question

[Don Wilhelm]

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.
