I can lift the grounds on it, to break ground loops, but this did not
help. So, I think I answered my question, before I asked it. So, for
$10, or so, what can I lose. I will give it a try...
Getting this to work properly and consistently is getting frustrating.
Tnx for the advice,

Subject: [Elecraft] KX3 IQ using NaP3
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
73 Al, ve7ear
