Hi John.
1. I noticed that although most PSK31 signals I receive are showing
the two phase positions as displayed on the scope at 180 degrees,
some are consistently at less angle than that, typically down to
about 135 degrees. When I say consistently I mean it is obviously not
just a

Hello John,
As said by Vojtech the big problem is the synchronization. As there is no
specific synchro signal, you must synchronize of the signal itself (using
some non-linear function). The synchronization is primarily done for the
theoritical modulation speed with the hypothesis of a pefect

of MT63. I configured Contestia with 16 tones and a bandwidth of 1K. The
sensitivity of the two seemed to be the same and the wpm rate appeared to be
close.
I then tested both modes with the HF path simulator
