I posted this question in the Car Audio/Video section but got no response so I'm trying again in the AHL where all the cool people hang. Every car radio (to my knowledge) has their AM and FM presets separated and I would like to know why. I listen to a few FM stations and one AM station when I'm flipping through channels. It is such a hassle to switch over to AM before getting to that memorized station. Why can't the radio save favorite stations on the same set of presets regardless of AM or FM? Haven't we advanced as a race to be able to do this?
