I thought at the price I paid for the KX3 I shouldn't have to do the compensation nor run the KX3 at such reduced power once compensated. My trusty old FT817 worked fine.
I also assumed Elecraft would address the issue with an updated KX3 -ie an 'KX3s' at some point.
So I sold it awaiting the 'upgrade' which turned out to be the KX2 !
Which is far more stable out of the box.
I'm happy to now order a KX2!

The KX3 was actually more stable than my original 144 MHz transverter's TCXO, which I had to replace with a better TCXO to get the transmit drift to satisfactory levels.

It seems to heat up a little faster using JT9, but it's still managable. I don't mind taking a few minutes between QSO's to let things cool off. From my understanding Gemsproducts.com already has KX2 side handles in the works and I will definitely pick some up and see how they work. I can only imagine that any more metal on the side to pick up some extra heat will only be a good thing.

I had 3 back to back QSO's and on the last transmission the PA Temp got up to 47C (~117F) which doesn't seem too bad. As it cools off there is no drifting or slanting of signals on the waterfall either. I think the 1 minute on/off duty cycle of JT65 is very doable with the KX2, and WSPR might be pushing it. The other night the sideplate got quite hot running WSPR at 5 watts.
