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

Re: KX3 IQ using NaP3

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.

Re: KX3 IQ using NaP3

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...

73,
Peter

Re: KX3 IQ using NaP3

OK, so I installed NaP3 as I said before.
Now I got my KX3 hooked up, set the rig control to KX3, connected the
I/Q output cable to the Creative Xfi soundcard on my laptop, set the com
port to the same as found with the KX3 util (com3 4800 baud) and it
worked "out of the box"

I must confess that this was indeed very easy to set up. I will play
some more....:-)

If you want screenshots of how this looks, just let me know.

73,
Peter

Re: KX3 IQ using NaP3

Go to panadapter .com and download ver 2.6 it does a much better job of getting rid of the zero freq spike.

Re: KX3 IQ using NaP3

Tried it Bob: Spike still there. No difference with the previous
version. I already had it at -110 dBm so not really an issue but using
the I/Q cable supplied remains disastrous, you need the galvanic separation.
I could create the overload warning in 2.6 but the software kept running.

NaP3 uses 90% CPU in task manager regular breakups in audio
I like the "dual receive" over two audio channels.

HDSDR uses 20% CPU.
But the interaction via OmniRig to the KX3 is much slower

It is not due to running too many other applications. The 2GHz dual-core
AMD CPU has enough room like 2.7 GB of memory.

Still a lot to find out here

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.

Re: KX3 IQ using NaP3

In reply to this post by pa0pje

I use an i5 cpu under win8.1 and can run using either an external emu 204
(USB 2.0)
or the internal realtek audio on my asus sabertooth motherboard.

I no longer bother with the emu...the realtek hd is better.

I can sample at 196k with cpu at 10%

nevertheless, i too would like to hear details of the setup specifics.
