Hmmm, when it's sunny I must sort things out, I suspect the LNB may be on the wrong polarisation but TX isn't as strong as it should be.

Sounds like your dish is not totally aligned.

How does SDRC calculate the SNR?

Well,

I've been silly busy for the last two years since putting up the dish, but now have time and enthusiasm to get it sorted out.

SNR - Peak signal versus my idea of noise, an average of the lowest 10% of data - or something like that. Very close to what you see on the screen.

I receive the PSK Beacon with -73dBm with 80cm Offset Dish, Bullseye LNB and PlutoSDR.
Had aligned the Gain of the PlutoSDR with a -73dBm Signal on 739,750MHz from my Stabilock4040 Testset.
So the readout on the SDR-Console is comparable.
