@sleepybisexual i mean technically speaking fm is just a way of encoding informationyou can do digital transmissions using frequency modulation or amplitude modulationbut yea normal radio is fully analog. you can tell by the way it sounds when the signal gets worse:analog radio will get quieter and noisier and digital radio will be a lot clearer and instead just not play back anything when the receiver was unable to capture enough information to do error correction@MagicLike
