AM band frequencies has greater range under the right ionospheric conditions.
In the event of needing to communicate in an emergency you must assume that the right ionospheric conditions will not be present and that you are limited to line of sight.

- dghlsakjg 3y agoThe point is that anything besides line of sight is unpredictable, so the ability for AM to sometimes reach around the world is irrelevant if you need to know how many people it will reach, which is, more or less the same as FM. In other words: you really don't need the ability to sometimes unreliably broadcast icy road conditions, or a tornado alert, to someone three states away.
