FM is more affected by physical barriers (buildings, etc.). Range is around 30 miles. AM range is around 100 miles during the day and further at night.

Don’t states with frequent hurricanes still recommend switching to AM in the event of disaster? There are a lot of situations where cell phones or FM may not work, but you could get an AM signal.

See this comment: https://sh.itjust.works/comment/11323676 on an alternate thread to this same discussion which gives a great run down of AM & FM radio systems.

Would be nice if phones came with am/fm radios built in

It's a shame that they took out this feature from smartphones when they killed the aux jack

They used to, back when we lived in a real society

I’m not sure what people would do with normal radios, but people in a severe weather area might own a weather radio that gets alerts from NOAA, and that’s on VHF, though they usually have AM/FM as well. I lived in tornado alley for a while and yeah, we would listen to whatever we could receive (FM in more populated areas, but AM when way out in the sticks) and we had a NOAA radio too.
