Weak audio output is very common on 2 meter FM in my area - seems a lot
of guys got the idea
somewhere that with FM since you have full power out all the time you
need little modulation. I have
to ask a lot of ops that have a full scale signal to speak up - you hear
it all the time on repeaters
as well- dont worry you are not going to ' over deviate' if you speak at
a good level and have a
decent mic gain setting. The other problem is the guys that then tell
people that they are
' driving it too hard' because they have to turn their volume down when
a station that is not whispering
comes on. They are so used to talking to mumble mouth Joe that they have
their volume all the way up
all the time.
