Could anyone tell me how a radio detects signals vs.
static? There is a
little gauge on my radio that moves depending on the amount of noise vs.
signal. I would guess that the digitally tuned radios that skip over the
frequencies that are pure static work in the same way. What is this way?
Generally the gauge is a reading of the AGC (automatic gain control)
level being applied by the radio's IF. There are many other ways to derive
this signal, but this is the most common one.

How is this AGC level derived, and how is it compared to the signal?

I know it may seem like this list has merely become a free-for-all in
light of recent topics, but isn't this question MUCH better served on a
ham newsgroup or list, of which there plenty??
