Default Tuning SSB on Kaito/Degen 1103

Help!

I cannot seem to properly tune SSB on my 1103 (it is a Degen from
China). I have the sparse manual that comes with it, but following its
instructions (tune to channel in AM, then hit SSB button and use the
Fine Tuning knob) does not accomplish much. In fact, when I turn on
SSB, there is very little coming out of the receiver at all (no noise,
no signal, no nothing). I know that I must be missing something simple.


I have been listening in the 80/75-meter band (3500 to 4000 kHz) and I
can tune in some "Donald Duck"-like voices, but switching to SSB and
fiddling with the Fine Tuning knob seems useless.

Any help is greatly appreciated!


Not much you can do. The one advantage a synchronous AM detector has
is that it can be phase locked to whatever is left of the carrier.
Without being able to do that, some amount of phase distortion in the
output of the product detectable is unavoicable unless you go the
Indepedent/quadrature modulated route. There is simply no way to
recover the phase relationships, so some the donald duck sound is a
fact of life with SSB reception.

Thanks,
