Hi Martin, many thanks for your answer, your video, and the idea on how to test "against" the cw tone(s).
My zig-zag-phenomenon just happened again. Now I did what you suggested while that was the case, and guess what: Super-steady cw tones to be heard. So it does not seem to be me, great.
Greets, Sebastian
Hello there!
I'm using an Adalm-Pluto-Setup for QO-100 in conjunction with the dual-port Leo Bodnar GPSDO (one out for LNB, one out for Pluto).
Sometimes I enable the Geo-Beacon display in SDR console just for the heck of it. So, often the display is
almost a vertical straight line, as one would expect. But sometimes I see quite a zig-zag pattern, and the frequency
shown, wiggles around 5-15 Hz (+-), within seconds (not the expected shift within 24h's or so). And then, its gone, and I'm back to the almost vertical line.
Whom to trust? 
Is it worth chasing down some rabbit hole? I mean, measuring things again, just to be sure, would be not a big deal, but maybe someone on the forum has past experience or insight in that matter... before I carry some test equipment to the terrace to check if everything is still really fine on my side. I'm using SDRC build 2870.
PS: I read about past known stability issues with the beacon in that matter, but those threads/articles are ~2 years old.
Many thanks in advance for any input.
Regards,
Sebastian
Hello there!
I'd like to ask something that I did not find in the documentation, neither was I able to find something concrete in the forums about it.
-> What do the percentage sliders for "RX filter" and "TX filter" exactly do (Radio section on the left side) ?

My use case is QO-100 in SSB and FT8 via Pluto.
Many thanks in advance!

Sebastian
(I posted the same question in the sdr console forum "forum.sdr-radio.com:4499" 3 weeks ago, but unfortunately got no answer, so trying it here
