Peaberry v1 SDR Image rejection problem

Hi, I have the V1 rev A peaberry and I am struggling to get any image reduction using the raw and Fine sliders in HDSDR, I am using the USB cable only and the onboard soundcard, I know I can use an external soundcard with the V1 but when I add a cable from Line out in the Peaberry to Mic in the PC I get no receive via my PC soundcard so I can't test whether I will get a good image reduction that way!

I get good receive with the Peaberry using the onboard soundcard but just a complete mirror image and I think I get the same problem in transmit (no working sliders) so tx is out the question.

Any ideas?

Regards Carl.

Failure to balance out the image is because one of the two channels carrying I/Q data isn't functioning.

The V1 can not be used by plugging it into a sound card.
