Kim,
There was a lot of communication in connection with S-meter calibration. If
there was any definitive solution, I missed it too. I also found my meter
extremely generous with the default settings. I could be wrong but it's my
understanding that a 50 microvolt signal at the antenna input should produce
an S-9 on the meter. Unfortunately, I don't have the equipment to create
this condition. Perhaps this e-mail exchange will bring forth some better
information. In the meantime, the following settings seem to work for me:
S0 -0 counts
S1 -7
S2 -12
S3 -18
S4 -24
S5 -29
S6 -34
S7 -39
S8 -44
S9 -50
+10 -58
+20 -66
+30 -75
+40 -87
+50 -100
+60 -0
Again, no scientific basis for these settings but they work for me. Good
luck!
73, Jack-W9OWO

And I must also be more tired than I thought since I'm really concerned with
the S-meter, not the A-meter...

Wow. My values are quite different for the default values. For example, in
my case I need 107 counts for S-9+50 dB while the default is 221. S-9 is
displayed for me with 55 counts while the default is 89. All of mine are
much closer together than the default values.

S meter much more sensitive compared to the default values. Does this
calibration affect the AGC itself, or only the displayed meter value?
