Hi Jim,
I'm running NaP3 v2.8.8 on Win7 Pro 64bit with my K3, so this may not be
applicable, but it could be worth a try.
In the NaP3 help file under the Menu/DSP contents
where it tells you how to do the calibrate that you have previously
done. It also tells you how after you have done your calibration you can
then set the WBIR to *Manual*. Try that, I believe it will force NaP3 to
maintain the preset *Manual* levels even after the changes during transmit.
hope it works for you

I'm running NAp3 v2.2.4.2 on Windows 8.1, connected to the RX I/Q
port on my KX3 at one end and to the Line In jack on an iMac on the
other end. As some other folks have seen, there is an initial issue
with "images" or "duplicated" signals when NaP3 starts up. Ken (W0CZ)
tipped me to a way to get rid of the image issue by opening the NaP3
Config panel, going to the DSP tab, and then doing a "Calibrate".
This works quite well and just about completely eliminates those
images. However........
When I key the KX3, I see my own signal (quite strong) on the NaP3
display and this completely throws out the calibration, bringing back
the images, big time. I have tried several things to eliminate this:
First, I tried using a PTT switch with the KX3 instead of QSK - I
still see my signal on the pan display. Then, I pressed XMIT on the
KX3 prior to keying it - no change, still see my signal. Next, I
built an audio isolator to put in the line between the KX3 and the
Line In jack on the iMac. No change. Finally, I wound the cable
through a 2.4" mix 31 ferrite core nine times, thinking that maybe RF
was somehow getting things hosed. That didn't help.
So, my questions are: why am I seeing my signal from the KX3 RX I/Q
when I transmit? Shouldn't that line be cut off completely when the
KX3 goes into transmit? If not, can this be changed so it does? :-)
