There is nothing wrong with the quality of AM radio. It transmits almost the same audio bandwidth as does FM. The problem is the cheap and crappy radios designed for the USA market which have flooded the market. Whatever, try getting a high-quality AM radio and having a listen. For example one of the upmarket SDR radios with variable IF filters.
