Hi Jonathan,

many thanks for the detailed explanation!

Unfortunately I'm not (yet) aware of the preprocessing (except for downmodulation to baseband) taking place within the (ham) radio - what _could_ happen to the signal? And what would be the optimal precondition for gaining any SNR information out of it?

If I know that to ask for I can investigate on how the preprocessing in the radio.

Best regards
