[Elecraft] K3 S Meter

[Dave G4AON]

Regarding the comments to alter the scale settings for the S-Meter, all 
I can say is that with the current firmware (MCU firmware 1.66) and the 
suggested default settings, the K3 S-Meter is the most accurate I've 
ever measured.

For S9 at -73 dBm (50 uV PD), S9 +20 occurs at -53 dBm, + 40 at -33 dBm 
and +60 at -13 dBm. It isn't quite so good below about S6 or S7, but 
heck it's not broken so lets not try to fix it!
