Kim,

I just checked my O II.  Cranking in ATTN does affect the S meter reading, 
as does switching the preamp in or out.  If you reduce the RF gain, the S 
meter will rise unless it is below the noise level.

QST reviews, etc., shouldn't necessarily be relied upon since they describe 
earlier versions of firmware.
