Radios use antennas to capture radio signals, which are then demodulated and amplified to produce sound
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
AM (Amplitude Modulation) varies the signal’s amplitude, while FM (Frequency Modulation) varies the frequency for transmitting sound.
FM is less susceptible to static and interference, resulting in clearer sound.
Ham radio, or amateur radio, is a hobby where users communicate over assigned radio frequencies without commercial purposes.
