I do understand that my statement below may not make sense for digital 
modes <grin>.

I've heard many  perfectly readable signals that sounded like they were S9 but were, to my surprise, an S3 or S5. Except for contests I like to send and receive accurate strength reports.

>>> Check your RF gain calibration using the Elecraft Utility, check your S meter calibration. Make sure that you don't have something else like the Pre-amp on causing an error in the reading.  Make sure that you don't have the Sub receiver on and the Sub AF audio up, or RF up causing it to look like it's getting stronger.  r.
