[Elecraft] FM transmit audio level

I continue to get complaints my mic audio is too low on FM.  So today 
I ran the mic gain to 60 and they said it only slightly better, so I 
advanced deviation to 6.0 which is too wide for normal deviation, 
still light audio reports.  I have no problem on SSB with my Heil 
HM10-5 desk mic set to gain=20 and had no problems using it with my 
FT-847 on any mode.

So I wonder if there is an internal mic gain pot that can be adjusted 
for FM?  One person offered that maybe the radio was selected for 
Narrow Band FM, but I do not see any place in the configuration menu 
that has such a selection.

Of course 15-KHz FM used to be referred to as NBFM when the standard 
was 30-KHz.  But I'm guessing the current term refers to 12.5 KHz.

Anyway is there a way to adjust this?  I prefer to keep my mic gain 
set to 20 so I do not inadvertently splatter all over an HF band 
because I forgot to reset it.
