I believe this was covered in the User Manual for v2.2
"SNR estimates no longer saturate at +20 dB, and large signals in the passband no longer cause the SNR of weaker signals to be biased low. Times written to cumulative journal file ALL.TXT are now correct even when the decode occurs after the T/R sequence boundary. In FT8 DXpedition Mode, AP decoding is now implemented for Hounds when the Fox has a compound callsign." On 5/14/2020 10:55 AM, Al wrote:
Just FWIW... I have set up a test where I have 2.2.0-RC1 and 2.1.2 running in parallel on the same PC from the same audio source. I notice that the SNR reported by 2.2.0-RC1 is consistently more optimistic vs. 2.1.2. In some cases up to 13db greater on strong signals. Most signals report at least a few db greater. Just an observation.. AL, K0VM
