I was not aware there was a compelling reason for analog cell phones to
stop using FM. Sounds like a solution looking for a problem.

FM audio is boring -- no entertaining high-pitched tones from solar
prominences which would definitely be heard on AM audio.

OTOH, AM video is boring. FM video is better. As I said before, the Y
[luminance] signal should be carried on an FM wave rather than an AM
wave.

Analog radio-frequency audio devices should use AM.

Analog radio-frequency video devices should use FM.
