Hi Boris

I think you need to specify costas-alpha as 0.05 and gain-mu as 0.001 as
your starting point. Hope this would help.

We've fixed some bugs in the mpsk demod since 3.1.3.  You could either
try the trunk, or stay tuned for a few more days when we expect to
have the 3.2.0 release out.

Thank you Bill and Eric.

With the change of the suggested 2 parameters dbpsk and gmsk reception
appears to be stable.
The dqpsk is still not working properly.
I will try the trunk as well. The 3.2 release seems very close :-).

Regards,
Boris
