The AOR AR7030 Plus does indeed have a synchronous circuit fitted as
standard. It is the notch filter/noise blanker that is optional. The
four standard filters offered are excellent and well-chosen.

I like my 7030+ but I'd have dumped it if I couldn't put in filters
better suited to my tastes. The stock ones are narrow enough to give
muddy sound or wide enough to let you hear hets from an adjacent channel.

Fortunately, it's easy to find and add filters, and if you choose ones
with steep skirts you can get beautiful audio without losing performance.

Also, the sync detector is included on all 7030's. Lucky was probably
confusing it with some Lowe receivers.
