Very cool. Thanks for looking at this.
I agree re digital modes. Also, Fusion radios tend to have some
dithering built-in, or something. There always seems to be some
constant low level white noise on those radios when in YSF mode,
for some reason. I don't hear that on DMR or DSTAR. To be fair, I
don't have any YSF equipment myself, and am hearing this through
DMR, but theoretically, that shouldn't matter.

Thanks for the message. When I put the AGC code in, I was playing
with several functions and never really did finish the work on
this. Today I looked back. at what was included and it is pretty
rough. So, I am playing with a new (for me) algorithm and it
seems to perform much better than the included code. Not sure how
I will expose the tuning parameters (threshold, slope and decay),
but I am continuing to test. If I allow dynamic updates to the
parameters I will have to protect the internal structures from
being modified while audio is present.
For me, the modes with the greatest range are DMR and DSTAR on the
loud end and fusion on the quiet end. Not that the AMBE is
different, but the different radio manufactures tend to have
vastly different front end gains defined by default. Playing on
several of the bridges where all of these modes tend to be
