He says he put a "discrete" resistor in parallel.? Could be SMD or thru-hole.
Sticking a discrete SMD resistor on top of an existing SMD resistor is quite easy.
As Allison says, it's like stacking bricks.?
Easier on the board than trying to remove the old one first.

Wow, you must have a rock steady hand to parallel a through hole resistor alongside the SMD resistor. I would not say I have Parkinson disease but my hands are not that steady.

I think I will see if I can find out what the immediate amplifier is after the microphone and the ac component of the audio from the Mic is and see if I can bring about the idea of a pre-amp with gain control. I think the only real problem would be clipping but if you check everything out rather than just stick a guess in it should pan out.

By the way thanks 'all' for the info. I would probably take that route too If I could keep my hands steady.

Indeed, I initially thought to add a mic compressor, but reducing the value of R63 by adding a discrete resistor was the simplest thing to do. No smd was removed. It increased, probably doubled the average SSB power so I can more easily drive a small amplifier or whatever.
