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, Joe K9LY |
