- gwbas1c 2y ago> The ability to receive multiple signals simultaneously is in some cases considered beneficial and is one reason that the aviation industry, and others, have chosen to use AM rather than FM for communications.
- retrac 2y agoIt's also possible to detect the presence of an AM transmission (if not necessarily decode) at a much lower received power than with FM. With FM there's little in the way of graceful degradation. As signal strength falls it can go from full fidelity to silence with very little transition.
- dumbo-octopus 2y agoThis makes AM radio more fun to listen to, as you get knobs for both your radio and your mental “tuner”. At night, you can pretty consistently hear 3+ broadcasts at once, and listen to them all simultaneously a la overhearing many conversations at once in a busy room.
