[ICOM] MKIIG Transmit audio problem

[Jack]

I have a used and modified MKIIG.
I can not get the audio properly set on FM.
I have tried the stock mic, DTMF mic and Heil Traveler mic.
Transmit audio on FM is now set on Ø (zero) and I have 'fooled' with the 
compressor settings yet I continuously get reports of muffled audio.
Is there a way to adjust the deviation? Is there anything else I can try?
