Elecraft K2/100 = S9 (digital S-meter)
Yaesu FT-1000MP = S9 (main and sub rx's, digital S-meters)
Icom IC-756Pro3 = S9+3 dB (analog S-meter), S9 (digital S-meter)
Kenwood TS-830S = S9+3 dB (analog S-meter) (1 uV setting = S4)
Years ago I calibrated the S-meter in the TS-830S using a metrology lab
calibrated HP-610C signal generator. I surmise that the Icom's S-meter
was factory calibrated at S9 using 50 uV. I therefore believe the -73
dBm output of the my XG1 is actually -70 dBm (70.7 uV).
Or, you could surmise that the K2, FT100 MP main, FT100MP sub, and Icom
digital are accurate, the Icom analog is 3 dB high and that the Kenwood
has drifted 3 dB since the cal was done so long ago...
Or, that the XG-1 is 1.5 dB high and all the radios are +/- 1.5 dB of
that :-)
Enjoy!
