Nonsense. You obviously don't listen to weak FM signals which can be
heard, but with noise. Ham radio operators using FM do it all the time.

My disagreement here is with your original statement "There is no
static, hiss, or pops on FM radio." That statement is too broad to be
correct. There are lots of exceptions.


Yes - especially if by "FM radio" you include the standard broadcast stereo
imlementation - where the stereo difference signal gets progressively
noisier, meaning many radios include a force MONO button, as the stereo sum
(i.e. mono audio) "lasts longer" - and clear mono may be preferable to poor
stereo?

I realise this is because the difference signal is carried using additional
modulation techniques, but when talking about "FM" radio as a consumer
product, most people mean FM VHF stereo as broadcast, rather than a purely
FM modulation technique?
