[Elecraft] SDR software for KX3?

[WB4JFI]

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 adjustments for phase and gain differences, so you don't need to adjust those with External mixer controls.  Try Rocky first, it's probably the easiest to set up and use.  It can also automatically adjust for your sound card and rig differences.

If you are having so many problems, be sure to check your cables.  I have had a couple of commercially made cables that were defective, with partial shorts between the various connections.  I had trouble with I/Q balancing until I found they were bad.

Good luck.  73, Terry, WB4JFI

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.
