Dale,
I like and use a SignaLink USB and like it. However, almost any of the popular
interfaces will work. Or, you could just use the mic and headphone connectors
on your PC and run cables to the mic and headphone connectors on the KX3. That
can work also.

G'day all,
I am thinking of using my KX3 for digital work and also running it through
Ham Radio Deluxe.
What is a good interface unit, maybe Digalink or Omnirig?
What is the best way to connect to a laptop to use HRD?
Suggestions please!

I had a lot of trouble until I put a ground-loop isolator between the KX3
and the PC. The grounding at my QTH is a bit less-than-perfect, and I was
getting a 60Hz+harmonics buzz by connecting the PC to the KX3. Not saying
it is the case with you, but it's just another one of those things.

I think I'll be looking at the cables, I seem to be picking up some 60 hz on
the kx3, fairly low level but this is on the battery so it must be coming from
a connection somewhere. ThTs probably why there's always a log spur at the
center frequently .

Hello Tom.
I have had success with using several SDR software programs (and sound cards)
with my KX3. It shouldn't be that hard. I've used Rocky, hDSDR, a few
variants of PowersDR, SDRsharp, and a few others, on various Windows and Apple
(iPad, iPhone) computers.
Most programs have internal

Well I just tried nap3 and while I can get a spectrum there are so many

In order to rule out the soundcard I bought a emu0202 and by adjusting the two

I can run the optimization for images and it d
Thanks to all who replied, Mike K2MK got me going. For the record for

Guys,
The one that really works well is NaP3. It was originally set up
for the K3, but the latest iteration does a great job on the KX3. I've
been running with the software for about a year or so, and I now don't
know how function without it.

Has anyone tried to hook up their kx3 via the IQ output to SDR software?
I have so far tried three different programs, hdsdr, sdr-radio, and SDR sharp,
and they are all the same. I get images that run in different directions as I
tune. I tried everything to get get rid of them to no avail.

Hi Fred,
You probably mean you use AFSK A for RTTY. For JT65-HF you want DATA A. LINE
IN is correct and MIC+LIN off is correct although I suspect the K3
automatically turns MIC+LIN off in any of the data modes.
I use VOX for all data modes. Never had a problem.

Use DATA A with the same settings ...
2. What's the best way to key the K3? On RTTY, N1MM/MMTTY key the
rig via the CAT port.
WSJT-X can key via software command, RTS or DTR *on a separate port

Hi Fred,
Thanks for the pointer. Yes, I had it set to 1500 watts
Your suggestion got me thinking along similar lines and I checked out my
setting for "Amplifier Key Interrupt" under VSWR settings. It was set (by
default I presume) to a very high value, so the amp PTT was never interrupted
Hi Gary,
Have you set the KAT500 Amplifier Key Interrupt Power configuration? The KPA is
delivered with that set at 29 watts so if the tuner sees more than 29 watts it
won't open the keying line. You have to set that parameter in the KAT500
configuration to "Optimize for Elecraft KPA500".

Thanks for the update Wayne,
For myself the main use will be to interface to a 24GHz to 144MHz
transverter, so the issues arn't as great a problem. Although having good
dynamic range and adequate sensitivity would be useful.

Hi Dave,
The KX3-2M module occupies less than one cubic inch -- that's about 1/15th the
space occupied by the K144XV, the 2-m module used in the K3. Given this, we had
to make some design tradeoffs. The KX2-2M's sensitivity is nearly as good as
the K144XV's, but the latter has higher power outp
