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!

The two-pass is the default decoder used in WSJT-X recent SVN code.  If you run Linux, grab a copy via SVN, compile and try it out!  There is a nice wsjtx-superbuild script that makes compilation very easy, including pulling in the modified Hamlib3 source.  I can post the commands here if needed.

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.
