Ken,
I agree with your statements, but would like to point out that it
doesn't have to be that way. If you borrow a top quality calibrated
signal generator, or spring for one of the Elecraft receiver
calibrators, and borrow or build a calibrated step attenuator, you can
quickly make a table of what your S-meter really means. I've done that
with my transceiver and keep the spreadsheet in the back of the logbook.
It's great to be able to give a difinitive comparison when someone asks,
or know quickly what your F/B is or whether all of your antennas are
working (if you note the difference in level from stations in a few
different directions on all your antennas when the are working!).
OTOH, getting a 30 over report always makes me think something must be
working!
