Thank-you for the reminder, Markus. My silly error was apparent after reading the first few words of your email!

Hi Joe,

are you applying the PSK modulation with an external mixer or XOR? Then you 
will need to undo it with another mixer in the pickup path, otherwise the PLL 
script will try to eliminate the modulation.

However if you use the SpecLab script which generates EbNaut from periodic 
actions, the software will internally generate phase reversals for the output 
and undo them again before phase comparison.

Best 73,
Markus

Just a carrier tonight. Perhaps there was a problem with the
pick-up wire. It's disconnected now and the system is as it was
before.

8.2700075 kHz
