Tom,
Thanks for that tip. I so rarely go into the menu so was not even
aware of a mic gain "switch". I wonder what the level change is? If
it is 3-dB or more it might affect FM deviation sufficiently to "fix"
the low deviation reports I get. If that will accomplish the
deviation issue perhaps firmware can be added some day for FM mode
which will set the mic gain? I use my K3 on 6m/2m/222/432/1296 so FM
is more than a "funny curiosity on 10m" for me.
I'll have to experiment on one of the 2m FM channels and get some
on-air reports. I only have one radio at the present (the K3) so I
cannot monitor my signal on another radio to determine the affect. I
do long for the days when I had a service monitor at work and could
make such tests so simply. I am in negotiation to buy a used HP-141T
spectrum analyzer which would display FM deviation of a tone visually.
I was just "playing" with the NR adjustments this morning and noting
their effect - interesting. What's so nice about the K3: you own it
two years and still have stuff to discover about it!

Ed,
Don't forget there is a High/Low mike gain setting (MAIN:MIC SEL Tap
1 to toggle High/Low). Probably not much use to you unless it can be
somehow selected for FM only.
