[Elecraft] KX3 and Digital Modea

[Neil Zampella]

Has the Temperature Compensation been done on that KX3 ??

I routinely run m KX3 at 5 watts using WSPR & WSJT-X for JT65/JT9 
modes.    The Temperature Compensation has been done, along with the 
replacement of the standard heat sink with an aftermarket one.

By adding a 12 volt fan salvaged from an old desktop computer, I run JT9 
at 10 watts into Europe without issues.
