This is just a FYI but when operating portable and the KX3 is subject to 
warm air temps and being in the sun for a prolonged period of time, 
internal heating can lead to minor drift in freq (as reported by the 
radio) and the possibility of powering down it's output.  Obviously, 
making sure the radio stays out of the sun is one way of mitigating this 
issue but if there's ever a chance to further improve cooling it might 
be worth looking at.

The KX3 is proving to be an excellent portable SOTA radio.  I have 
modified mine to include the Side KX panels and cover 
(http://gemsproducts.com/) and use it with as Zippy 30C Series 4200mah 
LifePo battery.  Capacity and voltage stability of this battery allows 
full power SSB operation of my KX3 for several hours without any need 
for voltage dropping circuit.
