Oh ok! J9 - got it, now I have to look for a different schematic...959 - but I also wanted to caution you, and unless you have a hot-air station - this is going to be a labor of love going over nearly every solder joint on these boards.
Go back and look for the "white wash" - their cleaner rinse - they certainly did not do (more like doo) a good job on the rise and clean.
This is a sure sign of cold - poor soldering joints - and possible component damage, referring to the clarifier pot.
You might have to do up a 10K pot to replace the one they seem to have really washed out and lost some if not most of the composition.
Why?
The pots' output voltages are way too high.
Reheating the solder joints following the traces back to the IF by the VCO is where I would continue....
In TX see if you can even get the 10.695 side of this, it seems that you have to tie LSB to some extreme range of one of the IF's - your comment about USB being understandable while LSB (the inverted one) is having a harder time "decoding" tells me something localized to the two IF's you're switching between - the USB seems ok, the LSB is not - but in order to even get close you have to use an extreme measure on the LSB side.
So that takes me here...

You have TP5 and TP6 for Am/SSB IF 10.695/10.625 stuff

LSB is handled thru L25/L22 - you are looking at L22 - but L25 is also used but in TX - if something in the TX side throws you off, as in - tuning is easier for the TX than RX you can find yourself chasing after an obvious problem, but you also have to go back and look for "What IS Causing This Obvious Problem?"
So does that mean a goofy Mode switch or is the Clarifier sending the wrong voltage?
Well, if you don't mind - locate D51, D52 and D53 - by those L22 - L20
Measure voltage on the UNBANDED side - all should be equal - but ONLY for that mode that coil represents - so the mode should have a voltage, the other modes it would not - and see if there is a difference in the reading off those diodes in the modes they are supposed to be on.
The diodes are to steer power to the VCO for that mode,
Thx - have several schematics for Ranger/Galaxy boards but to which it's own???
Now I can work with what you are using.
