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) ?
[Blocked Image: https://dx-cluster.de/percentage.png]
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 
RX filter/TX Filter - percentage slider functionality?
-
It seems to be related to FIR Filter from PlutoSDR options:
It will work only for bandwidth under 2Mhz.
Try to set RX filter to 10% and zoom out to see full bandwidth. You will see that only about some signal will pass (middle).
Probably TX works similar and might be important for spurious emissions or DATV.
At least, this is what I could figure it out. I hope I'm not wrong.
