[Elecraft] KX3 IQ using NaP3

[Al Sather]

Greetings All

I am trying to set up my KX3 to produce a band scope/waterfall display 
using NaP3 (v2.2.4.3).

My system includes  a laptop running Win 7 Home Premium with a Intel 
Core i3 CPU at 1.33 GHz with 4.00 (3.68usable) GB of memory and a 64-bit 
OS. The modem I use is a USB E-Mu 0204 with the ASIO drivers supplied 
with the E-Mu 0204. The ASIO drivers appear to work better than the MME 
drivers.

I have 3 questions--

1. Do I need to set up frequency or global offsets.?
     I cannot find any reference in the KX3 manual or Fred's wonderful 
little book. My experience is that NaP3 appears to ignore offset values 
for the KX3.

2. Do I need to worry about the balance between the I and Q channels.
     My under standing is NaP3 does that, using WBIR. Furthmore, when I 
play with the input levels on the E-Mu 2040, the display reacts, and 
then returns to where it was.

3.  How does WBIR work?
    I am not convinced that I understand how to set up WBIR, and whether 
or not it is actually working for me. My displays is full of images and 
other noise, and the strong stations that I know are there are not visible.

A couple of observations--
I use commercial AM radio stations  (730, 980 and 1040 KHz) to do the 
training, but I have problems ridding the display of images. Also, I 
cannot see the AM stations on the band scope (perhaps I can on the 
waterfall, but I suspect it is mostly my imagination). But, when I click 
on the frequency, it centres and I can see the station, but not other 
stations. This is often true on SSB, as well.

My real success occurred when I left my station on while I went for 
lunch and did not get back to it for a couple or so hours. Most of the 
images were gone, even when I switched to 80M SSB. Also stations started 
appear on both the scope and waterfall.  I have not been able to repeat 
this success. So, it does not appear that NaP3 had not saved WBIR 
adaption. When I started up my system the following day, I was back to 
my issues.

I am looking for suggestions as to how to properly setup this system. I 
know it is possible, since I did it once.

Best of the Seasons to all
