Is it off on both upper and lower sideband? how about AM? Did someone mod it so that the clarifier works on transmit too? Hope not.
If it is off on LSB adjust CT2 next to C104 and for upper side band CT1 next to C105. You will be tweeking on a capacitor in series with a crystal. caution as it could stop it from transmitting (oscillating) if it isn't set right. best if you use a frequency counter to see if the stage is working right on frequency. Here is a diagram hope you know how to read one. If you dont and you attempt to tweek on this and that, you have a great chance that you could foul it up to the point it wont work at all or sound really bad. The main thing is to narrow it down where the problem is: Is it just LSB or USB or both? If both do not tweek on C1 or C2. I would say it is the 11Mhz crystal area. meaning the problem could be a bad varactor diode, even a resistor or capacitor failure in that portion couldmake it off frequency as the varactor is voltage controlled. By varying the voltage to it, the capacitance changes and therefore changing frequency.
If both uper and lower sideband are off then I suppose AM is off too. the reason you are not being heard as well. Adjust CT3 to bring it back on frequency. You got it CT3 if upper and lower and AM is off or if only lower is off CT1, if only upper is off CT2.
Good luck. I am not responsible for your actions. I am only giving my opinion and logic on this. here is the diagram, dont hurt yourself.....
