Still, the PL660 is a versatile performer. It uses the same sync detector

that worked as designed even from the get-go.

Is that the same as in the SW-77?
I had one and didn't like it much because it had a couple issues like
the tuning chuff noise and confusing programming sequence
although the sync detector worked much better than the 2010,
almost as good as the one in the E1.

Not sure. IIRC the 7600G is a newer design than the SW77, so the multi-detector
chip (CXA1376) may be newer too.
