I found this one:

I'd be curious to know what y 'all think of this.  I'd always wondered if 
you could send the signal
through a limiter or two to surpress the modulation, and then use that as 
your input to the mixer or
product detector and so achieve sync detection.  This idea (near the bottom 
of the page) seems
to be just that.

What would you use for the limiter?  FM-type limiter circuits, such as 
those that use 6AU6s beloved of
so many receiver designers?
