It will be interesting to see how the S/M/F settings work for you.
The potential issue you will have with THRESHOLD set in the 20uV
range is that there is no AGC action on signals below that level. So
a weak signal at a few fractions of a uV for example will indeed
sound "weak". If you crank up the AF gain as a result you run the
risk of having your headset blown off by the S-9 signal that calls you
next :-)
The lower threshold setting of 1-2 uV or so in your PROG setting will
do a much better job of leveling the signal strength playing field so
to speak.
The more folks that work with these settings for optimal
performance, the more we'll learn. I think it's been very interesting
so far.
