Howard:
The standard means given in the manual for setting the S meter
produces settings that are generally low, i.e., readings that ought be
S9 tend to register much lower than S9. Many people have simply goosed
up their settings so that signals they feel should be S9 register as
such. Elecraft produces a little minkit, the XG1 Receiver Test
Oscillator / S-Meter Calibrator, that creates a highly accurate .5
microvolt signal (at 7.04 MHz). Using this will give you a very
accurate S meter setting for 40 meters. I cannot speak for its
behavior on other bands.
best wishes,

I set up my K2 S meter per the manual. It appeared to work "normally"
with S9+ readings on loud signals. I then borrowed an X-gen and used
it to "calibrate" the S-Meter readings. The "calibrated" settings
were much lower than the "per manual" settings, i.e., a signal that
was S-9 would read, after calibration, about S-5 or 6. I don't have a
method for measuring the X-gen output. I do know that the K2 easily
picks up the 1 uv low signal used for sensitivity testing. I will
probably just go back to the earlier settings, but I was wondering if
anyone else had a similar experience?
