And the K3 includes bandpass filters for each band (and I think one that covers both 12 and 10M). I think I remember that the KX3 has a bit more phase noise, but keying is equivalent to the K3.
The KXPA100 is a great amp, though the whole setup with a PX3 is a lot of cables. It took me a few years to learn how to reconnect everything without looking at a diagram.
I attacked that issue, first by labeling both ends of everything, and then by first hooking everything up, and then bundling them with small Ty-Wraps (cable ties).
Other plusses for the KX3 -- a bit less current drain, important if you're running on batteries; and an excellent preamp, probably within a dB or so on 10M and 6M of a good GasFET. Also if on batteries, good quality batteries inside can do a lot to supplement outboard ones.
I've long viewed the KX3 and its support products as one of Wayne's smartest product offerings. At the time, I described it as "a home run."
