You don't need an amplified microphone. And you only get about 20%
average power from voice on SSB. That is 20% of peak. Trying to drive up
more than about 20% of peak power will cause lots of splatter and
distortion. Try backing way off on the audio.
Then there are possibilities of dried out electrolytics in the
transmitter audio or dirty contacts where cables connect to boards. And
I've fixed lots of radios at a distance by suggesting the PC board
mounting (and grounding) screws be tightened.
