[Elecraft] SDR software for KX3?

[Tom]

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. I get images that run in different directions as I tune. I tried everything to get get rid of them to no avail.
I also tried three different sound boards and different cables. No difference at all. Anybody have ideas?
Thanks, Tom va2fsq
