Right. Isn’t FM just flat out higher bandwidth? So unless it’s wasting that somehow it’s just going to carry more information. And for audio, that means sounding better.

The use of FM doesn’t inherently imply higher bandwidth. For example, those consumer-grade FRS/GMRS radios you get from Costco use narrowband FM, which typically occupies about 12.5 kHz per channel. This is much narrower compared to the 200 kHz bandwidth used by FM broadcast radio.

FM is simply a method of modulating the carrier signal by varying its frequency. The actual bandwidth depends on factors like frequency deviation and modulation, so FM can range from narrow to wide bandwidth depending on the application.

Good point. I was referring to the public airwaves with the layman’s definition of “a radio”. But that was how it was chosen there.
