Default AM Synchronous Detector Review: Sony ICF-2010 vs RL Drake R8B

Will wrote:

Interesting discussion. Just out of curiosity:

Is the sync detector on the Sony 2010 the same
circuit that is used on the currently-available
Sony ICF-7600GR?


Will, they both use custom Sony ICs. However, they are different designs.


Or, since that latter has a
switch-selectible USB/LSB that applies to both
the SSB and Sync selections on the tuning-method
switch, is it more like the R8's? Or something
completely different?


Without details on the internals of the Sony IC, I don't know. I have been
unable to find specific information on the web.

Given their behavior, I would expect that Sony design to be similar to
Drake's. The phasing method of side band selection has been around for
years.
