Hi, I am really struggling to remove Images using Channel Adjustment Panel in HDSDR! I am using the RAW sliders and get no reduction what so ever, The image is as strong as the actual signal! Any sugestions?

Thanks Carl.

VINL/VINR carry the I/Q data in analog form. You have a soldering error keeping one of them from working. Could be anywhere from U6 to U10.

Thanks David, I have checked and checked for the bad joint but it all seems to looks fine, Also the sliders don't work for tx either.

Hi,
What happens if you set HDSDR to "auto"? I have never had much luck with the sliders either.

Still struggling with this! I have not found a single bad solder joint so pretty sure I can rule that out, should mention my radio is a V1 rev A.

I tried Auto but nothing changes, I'm not sure the sliders work on tx either but that's to be expected? any more pointers?

Thanks Carl.

I was wondering if you were talking about the same radio here.

Since this is the V2 support forum and you have the earlier version, which was substantially different, we probably should re-map our advice parameters!

The V1 unit uses external sound in-and-out, for those here wondering. It has two audio jacks, and works much like the similar Ensemble RXTX.

I also have a V1 Peaberry, in addition to my newer units. Perhaps if we create a thread in the V1 support forum that could better help zero-in on your actual problem.

Thanks I have started a new thread in the V1 section.
