I was just looking at my 2002 handbook, and there was a circuit for a
synchronous detector, in the receiver chapter. It wasn't "simple", but it
was there. It also uses NE604s (the companion chip to the '602), which
might not be available any more.

Has anyone implemented a simple sync detector that uses as few parts as
possible?

Thanks
