We all know that AM broadcast radio fades when you drive under a bridge
but FM doesn't tend to nearly as much. Why is this? Does RF at the FM
broadcast frequencies propagate better? I thought the higher the frequency,
the more it exhibited "line of sight" behavior. Or is it because AM
shows the signal reduction more directly? Shouldn't AGC take care of
that?
