When radio audio mixer spread out from the antenna to the receiver. Radio receiver is acting to separate the voice signal in the form of electrical signals from the radio signals. And then expand to a higher amplitude. To send a speaker to output a sound ear to listen to a radio frequency transmission system 18.9 AMD AMD system in broadcasting radio broadcast. In addition to the waves with a frequency 530 - 1600 kHz, there are waves with a frequency range lower than this, which is called long wave and wave at a higher frequency, which is called short wave with the transmission system, AMD, which is mixed. The wave amplitude of the carrier wave signal changes based on sound waves. As the wave moves in the atmosphere Lightning or Lightning phenomenon Can cause electromagnetic waves The new wave of this happening can be integrated with radio transmission and AMD. Cause interference
