I have been under the lifelong impression that FM travels farther than AM, for some reason I have “about 60 miles and quality drops gradually” vs “about 90 miles and quality drops suddenly” stuck in my head as a statistic from childhood. I’m pretty sure it was something that my father told me as a child. Now that I’ve been education in radiation, I’m going to look up and see if he lied to me and I, like a 7 year old fool, believed him.
Typical MF radio stations can cover a radius of several hundred miles from the transmitter, with longer distances over water and damp earth.
That’s AM.
VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles).
That’s FM.
I really hate my dad sometimes. What a motherfucker.
Not the end of the world but it would have been nice to have it. AM travels much farther than FM which would be helpful in catastrophic events.
But the chances of something like that happening are very low. If you’re that paranoid, you can get a ham radio.
