Has this been resolved? I had a similar problem with the current utility and firmware as of 26 Sept. I had previously calibrated the S-meter to the XG2, then a few day later it was town from S9 to S6. I'm not aware of anything I might have done in the meantime to affect calibration. I recalibrated it, which resulted in OF=18 and SC=14. Unfortunately, I did not record the values for the first calibration. I didn't measure MDS.
