Thanks for the explanation Joe. I had not seen that before. Signals do not
affect the noise estimate which was one of the answers I was looking for.

Hi Andy,
Interesting approach. But how you know that it really enhanced the signal
detection?
The wanted signal is now close the wanted signal and that may disturb the S/N
calculation and you will see a better S/N values with your method without a

Joe,
Just a comment here. I use FT8 frequently and almost always on 2 meters. My
interest is in weak signals. I use a Omni VII here, with a transverter. I
have had some luck using my notch filter on very weak FT8

Been wondering how WSJT-X generates the noise power estimate it uses to
calculate SNR for each FT8 signal. Does it simply collect all the signals
and noise over the bandwidth selected on the waterfall and call that the
noise power level or does it take a quick snapshot of the background noise
