It's my understanding that the KX3 will "sense" the input voltage and
adjust power output correspondingly. That is, if I'm using internal NiMH batteries, power output will be limited to 5 Watts, and if I'm powering the KX3 from a 13.8 Volt source, power output will be allowed to go all the way to 12 Watts. Right? Well, here's what I'm experiencing: Let's say I've got my power set to 10 Watts using a 13.8 Volt source and my KX3 display indicates 10W output. If I turn off the KX3, unplug the 13.8 Volt source and run off batteries, my power out (as indicated by the KX3 display) is 5 Watts...fine! Now, if I turn off the KX3, plug in the 13.8 Volt source back into the KX3, and then power on, output is still at 5 Watts. I have to readjust PWR to 10 Watts to get 10 Watts out. Is that the way it's supposed to work, or am I missing a setting somewhere?

That's the way my KX3 #6 works too. It's what I'd expect.
