Hello,
I am trying to do FT8 on QO-100 with an Adalm Pluto SDR, on a 90 cm dish with a Othernet Bullseye LNB which is pretty stable
My Pluto has a GPSDO clock and I use the Geostationary Beacon feature, there is no drift at all.
A virtual audio cable makes the link between WSJT-X and SDR Console V3.2 build 2731.
The waterfall looks good and so does the audio in SDR Console :
WSJT-X seems to get the audio correctly :
However it decodes absolutely nothing.
The same configuration (wsjt-x and virtual audio cable) with a websdr instead of SDR Console works fine, the issue is consequently in my RX chain.
Do you have any idea?

You can't see it very well in the screenshot but there may be some drift after all. If you set "N Avg 1" (normally it's N Avg 4 or 5) in the waterfall, you can see it better.

Even small temperature variations can be killers for some modes at 10 GHz.

ft4 and ft8 run fine here with my tcxo driven pluto and a tcxo driven lnb (plus beacon lock)
