I've already fixed one aspect of this issue (will be included in the next software release).

After a page reload all is well. Adjusting the passband edge works when the cursor is dragged anywhere in the grey frequency scale area. When the cursor enters the waterfall area below the scale the edge dragging stops and reverts to passband tuning.

Here's the bug: As soon as you drag the waterfall just once then passband edge dragging in the lower half of the frequency scale breaks. It now behaves the same as a passband edge drag entering the waterfall area. Namely that the edge dragging stops and reverts to passband tuning.

So that problem has been fixed. What I'm working on now is trying to make edge dragging persist no matter where the cursor wanders to. But this is much more difficult.

Well, looks like I'm wrong about this.

If you mess around long enough things change and you get the behavior you describe. Where the passband edges will no longer continue to adjust when the cursor is below the lower red mark in your diagram.

I think I see what causes the problem. Let me see if I can develop a fix.

From your description it certainly sounds like an open attenuator. Especially if you're getting the self-test patterns, just attenuated by 40 dB.

Please send an email to sales@kiwisdr.nz (note ".nz") requesting a repair. We're having to figure out some sort of formal solution to this problem since a significant number of people are asking.

Thanks for reporting this.

It seems the rx4_wf4 FPGA file was incorrectly updated when the v1.692 changes were reapplied in v1.694. But I don't understand why that would of caused this problem. I'll have to go find out.

This will be fixed as part of v1.695

Okay, let's try this update again. Hopefully it won't cause your ATM machine to stop giving you cash.
