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? :-)
