I know this is anolder post appears to be quite relevant given the performance of NaP3 wih the kx3.
I'm having excellent results with the current beta version of NaP3 V2.1.5 running with LP Bridge V1.08 and the KX3. I'm also using N1MM and Log4om logging programs through LP Bridge.
I set the offset by band on the KX3 to 8.0 and the offset in NaP3 to 8000 on each band. I have not had to include any offsets by mode.
Only the display sensitivity has to be periodically adjusted mostly due to fluctuating noise levels.
This beta version has solved a lot of stability issues for me.
I'm just getting back into the hobby and things have changed immencely since I left so this is pretty new to me. That being said, I'd be more than willing help anyone else to the best of my limited ability if you're strugging with this utility.
