[Elecraft] [KX3] JT65-HF KX3 Freq Drift Measurements

[Gary Hawkins]

Hi David,

Thanks for the reference - I'd not seen this article.  While I've fitted 
a heat sink, it is a commercially available 3rd party option and I've 
not implemented the additional heat transfer techniques Lance references 
with his home made version.  This weekend I hope to do the extended temp 
compensation routine so I'll have a better ideal on how much better freq 
stability gets.  I'm sure I'll be posting results.
