On another note..................I am working on a quasi-sync detector, so I
should be able to build the prototype unit up this Monday. Basically, it
consists of a limiting amplifier (MC1350) feeding the squared up I.F. signal
into the LO input of an NE602. The unconditioned I.F. signal it fed both to
the input of the limiting amplifier and to the RF input of the NE602. It
should be interesting.
I've been meaning to get around to these things for the past couple of
years..........I'm glad that this radio project came along.

That should work when the signal is strong enough to keep it locked but
I think it would be prone to losing lock when the signal fades. I wonder
if the sync' in the R75 is actually a quasi design?

BTW- How do you breadboard your circuits?
