Since my post several months ago relating to issues with JT65/JT9 
operation with the KX3, I've done the temperature compensation, checked 
install of my 3rd party heat sink (from VE7FMN), played around with 
antenna configurations and got use to the software.  In the last six 
weeks of intermittent operation, I've made about 175 JT65 and JT9 QSOs, 
mainly on 20m.  Approx 20% of contacts have been JT9.  I'm usually 
running 10W into a fixed (about 60 degrees) 20m dipole about 15ft off 
the ground (HOA issues).  I've been using PSKreporter to track progress.

I must conclude from these results that after temperature compensation 
the KX3 is doing a good job with both modes.  Even though I'm using a 
unmodified SignaLink,  I can hear many more stations than I can work.  
Of the 175 contacts, so far 34 different US states.  Countries are a 
little harder to come by as there's usually to much competition from 
bigger signals.  All this with S7 noise on 20m!
