I think the decoder "sensitivity" is still the same, however, the two-pass method employs signal subtraction on the second pass, removing signals associated with stations decoded in the first pass.  This clears the way for stations that may have been missed in the first pass, including stations close to a strong station or even stations on the same QRG (as shown in my previous post).  On average, I think there are 10-15% (or more) decodes than with the standard decoder.  It's pretty crazy to decode two guys on the same offset that are 12-13 dB different in SNR!

Thanks for the informations! I will test it!

If you run Linux [...]
Not yet. Just on my Raspberry. But it won't take to long any more...

Does this have any advantage i.e. a better decode performance then WSPR-X?

At any rate... anxious for conditions to settle and start getting some TA action.
A good idea!
I'm on air as well but i do not expect much this time of the year.
