Hi Doug,

The mic gain setting is on 30 on a scale of 00-100, the speech processor is 
on with virtually no ALC movement except on the highest voice peaks. Audio 
reports are poor with the processor on and good with the processor off. The 
mic is an SM-6 desk mic.

The problem is that the IC-718 RF processing is set at +12 db at the factory 
when it should be no more than +6 db. I want to adjust it down to +6 db but 
the adjustment is internal and I can't find it in the service manual or on 
the schematic. I guess I will have to call Icom in WA and see if they know 
the answer.
