I have looked at your schematic, and I understand what it does. What I 
don't get is why you have just not added the "second arm" of the Costas 
loop into the 8170 architecture. I just don't have the 8170 schematic, 
but what I am trying to say is why didn't you just add the missing 
pieces? Too hard?

It's almost as if you built a new frequency receiver from scratch.

Cheers,
Magnus
