Sorry Ariel, Hit the wrong button...Should of course have sent it to the
list instead of you.
I tried NaP3 but I'm afarid I am too much a HDSDR type so I get stuck on
using PowerSDR and it's derivatives.
I tried NaP3 with my simple SoftRock mixer on 30 meters and found that
indeed it automatically calibrates the I/Q phase and amplitude and does
that quite fast. Using the second VFO I could receive signals but trying
to tune the first one does not work, it stays put on 0 Hz. I can choose
all sorts of transceivers but not the simple I/Q mixers, as in HDSDR. I
have HDSDR working with my KX3 and will hook it up to NaP3 and post my
findings.
To Al:
One of the most important things is to use an audio cable with an 1:1
isolation transformer between the KX3 and the computer/soundcard input.
Much of the noise you see stems from all sorts of ground loops.
To be continued...

The reason I am using LPB2 is because of this page. I know another ham who has
used LPBridge with his KX3 and all his settings are for a K3 and his works just
fine.
I was wondering what the list says is the best way to run NaP3.

Hi Al and Ariel,
I suppose you both know the existence and have thoroughly read this page?

I am also interested in replies to this post. I have only successfully set up
the KX3 using K3 settings per the Telepost.com website and that is without
using the E-MU-0204 external sound card.

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
