Joe, does the receiver hear the atmospheric noise in its most insensitive
spot? As long as the receiver can hear the natural noise level around it,
what difference does it make if it's sensitivity is 10uv or .01uv? The
answer is NONE. With all the racket on HF, a super-sensitive receiver is a
CURSE, not a feature. All the new radios are way too sensitive for HF with
their stupid S-meters showing S more than 1 with no signals. You end up
listening to racket and riding the AGC level control.

It's crazy....

Larry,

No, it definitely can't hear the atmospheric noise in its most
insensitive spot. So I'm pretty sure the gain is lower than it should be
at that spot on the dial. Otherwise, you're right... there's no point in
having a super-sensitive receiver when the atmospheric noise is what
limits your noise floor.

Tnx,
