I have to confess I am no fan of modifying radios to work with non-original microphones, I always set them up with the stock / standard microphone and if anyone wants to use some other microphone, especially an active one, the microphone, not the radio, gets to be altered.

I'm assuming the standard microphone is to hand - if the audio levels on all modes are OK on that microphone then I would tend to try to dissuade you from tinkering with the radio and instead try to work out why the alternative microphone is giving insufficient drive.

Is it really only deficient on SSB? SSB is the only mode where audio drive is proportionately converted into RF output indication, so maybe you only notice it more on SSB.
