Ant switching bug still present?

I see we still have the 'freezing' when initially switching from Ant A to Hi-z. To replicate it, start Uno at a VHF frequency on ANT A, then move to a low frequency (2MHz in my case) then select Hi-z. Waterfall etc will lock up. Clicking 'stop' and then 'play' corrects it.

In 1.21? What RF gain are you using? I can't replicate that here. Can you try with different RF gain settings (min / max)

Best regards,

Yes, 1.21.

I've just re-checked and it does it without fail.

1. Start Uno
2. Select 2MHz SR and dec 8.
3. Enter 400 MHz and ANT A will auto select.
4. Click on '160m' button (at this stage sr and dec will change )
5. Select Hi-z.

At this point the spectrum and waterfall displays stop working.

RF gain is set to minimum or the next step up. At one stage I though it was an overload problem, but it happens even with no signals applied. Note this only happens from a new start - band/ant switching works fine after the first freeze. It's not a life-threatening problem and once Uno has been re-started the problem seems to go away, but it is irritating!

I'm using registry reset and then following your steps and it's working ok here. I'll have to get some others to also check it.

This happens with max gain also?

I haven't tried max gain as I have some strong MW sigs around here. I have to go out now, but when I come back I'll give it a whirl. Thanks.

Back home now and I've just tried it with the gain at full and it does not happen. Only at lower gain settings.
