I was mislead in my initial assessment because I wan't watching to
ensure the selected mode, etc. was the same in all bands. There
does seem to be a slight increase in background noise when the RF
gain is turned down, with no antenna connected -- an all bands
about the same amount more or less.
With mode selected to FM, not only does the noise level jump up,
but so does the S-meter reading. Interesting -- but it isn't like I'd try
to copy a weak signal with the RF gain turned down ;-)
