I'm sure this question has been asked before, but I can't find any information 
about it.

In measuring the calibration of the S-meter in my KX3, I discovered it is 
extremely 
accurate, but only with the pre-amp engaged. With it engaged, S9 is indicated 
at 
exactly 50 uV (within the resolution of the display).  It is also very accurate 
up 
and down the S-meter range, with 6dB corresponding exactly to an S unit.  

I would have expected it to be calibrated with both the pre-amp and attenuator 
disengaged.  Is there some reason it's calibrated this way?

Also, when the firuware is available that automatically accounts for engaging 
the 
pre-amp or attenuator, will the indication be referenced to the pre-amp on or 
off?
