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. 73, Barry K3NDM ----- Original Message ----- From: "Tom" <[email protected]> To: "Barry LaZar" <[email protected]>, [email protected] Sent: Saturday, October 12, 2013 7:27:48 PM Subject: Re: [Elecraft] SDR software for KX3? 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.

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. 73, Barry K3NDM On 10/12/2013 5:04 PM, Jerry Flanders wrote: > I saw the same thing with several of the programs I tried, but finally > one worked OK without those images. > > It is: PowerSDR/IF Stage V1.19.3.5 > > SETUP IF: > > RIG CONNECTION - rig type K3 (NOTE - K3, NOT KX3)( also get your com > port and baud rate from the kx3 utility) > > IF FREQUENCIES global offset -5700 lo center (don't know what this > is) 8215000 LSB 650 USB -800 > > This should get you started. > > GL de Jerry W4UK > > At 04:35 PM 10/12/2013, Tom wrote: >> Hi >> 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.
