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.
