[Elecraft] [K3] RF gain calibration and S meter

Just ran the RF gain calibration with the new Mac K3 Utility and an XG2.  I
did it
a few times because I would get an ERR DSE error message when
calibrating the SUB rx on occasion.  I then went back and re-calibrated the 
S meter.  I've noticed three things.

1) The rx seems considerably "quieter."  The PRE is needed now where I
seldom
used it before.

2) Turning RF gain to minimum quiets the rx but the S meter only advances to 
S-5

3) I calibrated the S meter with PRE on and SMTR MD set to normal as Wayne 
recommended.  When I change the MD setting to ABS, the 50uv signal drops to
S-6 and cannot be adjusted up to S-9 with SMTR OF.

I would appreciate any help here.  I'm tempted to go back redo
the RF gain calibration using the factory defaults option.
