Broadcast radios are devices that receive audio signals transmitted over the airwaves. These signals are sent out by radio stations, which can be local or national, and cover various genres such as music, news, and talk shows. The radio waves are picked up by the radio's antenna, allowing listeners to enjoy their favorite programs without needing an internet connection. There are two main types of broadcast radios: AM (Amplitude Modulation) and FM (Frequency Modulation). AM radios are known for their long-range transmission, making them suitable for talk radio and news. In contrast, FM radios offer better sound quality and are commonly used for music broadcasts.
