It doesn’t have to be a big emergency, FM can still be very useful. A few years ago there was an earthquake in my city that wasn’t too big but we still had to evacuate the building. I don’t remember any damage in my area but because everyone was trying to make calls there was ZERO cell service. So a bunch of people were gathered around my phone listening to a news station for updates because I was the only one who had brought headphones. Without FM this ability is now lost.
