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.

received at all.

Any comments or suggestions will be appreciated. Thank you in advance.

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
