It seems to me that the SNR measurement of SDRConsole is not correct, according the following 4 images:
Tuning in no signal and without zoom we have 6 dB SNR.
Increasing only the zom and still no signal, the SNR rises to 18 dB !!! In both cases, the correct value would be 0 dB.
With the beacon signal tuned and without zoom, we have 37 dB SNR. Zooming in on the beacom signal has 48 dB SNR !!! In both cases the correct value would be around 31 dB. (37-6 or 48-18)
The SNR should be ZERO with no signal and should not change according to the zoom level!
