Networking Radio Broadcast Controlled by using Audio Mute Clock

This paper presents the audio and transmitter controllers to switch the broadcasting programs in the automatic radio broadcast network. The audio mute clock is used to control the controllers to switch the relays on and off via Programmable Logic Control. In addition, the controllers is used to turn on and off the transmitter when it is used as unmanned operation. From the result, it is shown that the proposed controllers can be accurately used to switch the automatic broadcast program. In addition, this controllers using audio mute clock can be used without the needed of computer, master clock and human intervention. In addition, it can be used to automatically turn the transmitter on and off when it is used as unmanned operation.
