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. Unless the 1103 is defective, chances are the OP is just inexperienced. It takes practice and patience to fine tune SSB signals on a small radio like this. I have an 1102, and there is definitely a learning curve involved. Once you learn it, however, the 1102 is surprisingly capable. Mike |

Thanks for all of the suggestions, I will give it another try.
Is it normal for me not to hear anything in SSB until I hit near the "sweet" spot with the BFO control? Thanks again! matt Mike wrote: In article , matt weber wrote: 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.

I normally crank up the volume once I go into SSB mode, so it's easier to fine tune. As you adjust the knob, you hear the Donald Duck voice, and then it suddenly sounds normal. Mike |

Hi Matt, all, from Ken in the UK,
Matt, the best way to resolve SSB signals is to listen in the SSB mode, ie, with the ssb switch on and the fine control set to the centre of it's travel. Remember, you must tune very slowly in one KHz steps, no good tuning fast, you will resolve nothing. Once you hear a strong ( to start with ) SSB signal then use the fine control to resolve the speech best to suit your hears and the signal is understandable. If you find you can't tune the signal in by means of the fine control then just adjust the frequency by one KHz one way or the other and try once again to resolve the audio. One final point, make sure you are listening on a band that uses SSB solely ( or a mixture of AM and SSB ). The best band to start with is the 'Eighty Meter' band early in the evening. If none of the above work then I'm afraid you may have a problem with your radio.....sorry. I do hope the above helps, cheers, Ken, G4KIR. "mcnowinski" wrote in message oups.com...
