[Elecraft] SDR software for KX3?

[k3ndm at comcast.net]

Tom, 
I, too, am running the EMU0202. first thing you need to do is shft the receiver 8KHz. That makes the appearance a bit better. I also notice extraneous garbage on the display. It doesn't seem to interfere with the overall operation, so I live with it. 

Let me suggest that you not exceed 96 KHz sample bandwidth and then use the zoom feature to look at less than the sample rate. I haven't thought it through, but I was taught that you need to sample 2X the bandwidth. How we are able to use a bandwidth equal to the sample rate is something I really need to think about. But, I suspect that is contributing to some of the garbage on the screen. And, Elecraft suggests that you should stay at 48 KHz due to internal flatness of the radio's response, anyway.

Hi 
Well I just bought a new outboard sound card and removed all previous cards. I'm now running an emu2020 and I can adjust the levels between the channels. I can minimize the images but as soon as you move up or down a while the images are back. I also have lots of spurious peaks making it impossible to distinguish between cw and spurs. There is no adjustment in software for the inputs but I can adjust the levels on the outside. The images look nowhere like what you see on YouTube. 
Getting pretty frustrated here 
Tom

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.
