This was really interesting. I've never gotten into HAM radio, I do remember
my uncle had a CB radio in his car when I was a kid.

Probably unrelated, but I just fell down a wikipedia rabbit hole wondering
why you almost never see stereo AM radio stations.  TIL that they can and do
exist, but politics & in-fighting along with a lack of fidelity make AM more
suited to the spoken word, negating the need for stereo.
