A.M. Radio Stations

A.M. radio stations transmit audio signals by encoding sound onto carrier waves within the amplitude modulation (A.M.) frequency spectrum. These stations broadcast over specific frequencies, allowing radios tuned to those frequencies to receive and convert the signals back into sound. A.M. signals are typically characterized by their ability to travel long distances, especially at night, due to their lower frequency and propagation methods. They are commonly used for news, talk shows, and music. While A.M. radio offers broad coverage, it often has lower sound fidelity compared to other broadcasting methods like FM, but remains a vital part of communication infrastructure.
