There is no static, hiss, or pops on FM radio. Fading (which includes loss

That statement is true only if the signal to noise ratio is high. If the
noise is strong enough, you will hear it even without fading of the FM
signal.

No, if the signal to noise ratio is that low, there *is* no usable signal
at all, and what you hear is the amplification of "nothing"...basically
the same thing you hear when you tune to a spot where no station exists.

True. If the signal fades, eventually you'll lose reception of *any* type of
radio transmission. AM, FM and digital simply die different deaths, viz-

AM - programme volume decreases and gradually disappears into noise.
FM - noise increases and gradually overwhelms programme.
Digital - nothing noticeable at all at first, then screetches and yelps and
suddenly disappears altogether.
