hey freebird, just wanted you to know someone's reading your post. i think the reason you havent gotten more responses is that your description is a bit vague. have you heard one of these radios operate correctly in the past for reference? do you have another radio there that sounds good on SSB? just to make sure its not interference. are you able to make out people's voices? try giving us as much detail as possible, and i'll do my best to try and help.

Hi Freebird,
Sorry to see nobody else had a suggestion. There is a fix for this, changing a capacitor in the SSB receive section. Pretty sure it's C89, a disc capacitor that gets changed to a smaller size, like 2 pf or so.
Try turning your RF gain down and see if that clears up the SSB receiver audio. If it does, there's a chance that this trick will help.
Of course there may be some other cause behind the problem you're having, but we saw a few of these 8 or 9 years ago new out of the box.

SYMPTOM -- Distorted receive on SSB
PROBLEM -- C43 has a 1pF capacitor installed which should be replaced with a 10pF, and C89 has a 10pF capacitor installed which should be replaced with a 5pF.
SOLUTION -- The easiest and quickest cure is to simply switch the two capacitors. Even though the schematic shows C89 as a 5pF, the 1pF works just fine. Realign L15 and L16. |
