Colin and all.

Well, this is interesting, and I'll let you guys know what the Kenwood tech 
says in response to my inquiry.

What Colin is saying makes sense, but at the same time, I find it 
interesting that a company would make a radio that you can't control the mic 
gain on.

Although, come to think of it, HT's are that way--what you hear is what you 
get.

Anyway, will keep everyone posted.
