I've never been able to get over 25db of carrier rejection according to
my Rigol DSA815. Not unless I move the BFO so far that signals are
unintelligible. If you adjust by 6db to allow for PEP equivalence this
is still only 31db of rejection.
In looking at the modulator circuit I don't see much of a way to
increase carrier rejection without major butchery, i.e. totally
replacing the modulator with a ring mixer which would allow providing
for a carrier balance adjustment.
