In Utah there can be blinding snowstorms that trap people in their cars on the side of the road. There are public service signs every so often, "for weather tune to AM 830" or something like that. It's great to pass one of those signs when there's a bunch of snow coming down. It helps you make a decision whether or not you should pull off and get a hotel room.<p>Could they move to FM? Yes, but FM reception could be dodgy in a snowstorm, especially when going through mountain passes. Knowing what I know from my HAM radio training, AM radio is fantastic in emergencies. One tiny little station can blast out a signal that can be heard from halfway across the country if given enough umph. Being on the lower bands, AM punches through the storm better too. It makes a lot of sense to put emergency and national weather stations on the AM bands. They're cheaper to run, and they work better in emergencies.<p>Some commenters here talking about right-wing political radio and sports wanting their AM radio bands available. People who listen to right-wing political radio don't do so from AM, or at least they don't need to. Podcasts and even FM stations out in red Utah are usually reached for first by my friends who listen to them.<p>I remember driving through the "four corners" area where Utah, New Mexico, Colorado and Arizona meet. It's a place home to many American Indian nations. It also has terrible cellphone reception. The first time I bought a paper map in years was when I went down there. You couldn't find your way otherwise.<p>I think of places like that when they talk about getting rid of AM. There's not a lot of money in AM radio, not compared to all the other media. At the end of the day, if you live in a _very_ rural place, AM radio may be your only source. I remember listening to a Navajo Radio station like this one[1]. The announcer spoke in Navajo. I remember driving through the reservation. It seriously feels like the 1930s. Frame houses but without any electricity plumbing or heating. The people in these regions are terribly poor.<p>For safety reasons detailed above, I would not drive a car without AM radio. For humanitarian reasons also, I would advocate for keeping The rural and the poor in mind when making a decision to keep a receiver that otherwise makes no sense in perhaps a very urban setting where disasters are not that big of a problem, like the Chicago area where I grew up.<p>1: <a href="https://www.ktnnonline.com/events/" rel="nofollow">https://www.ktnnonline.com/events/</a>
