Abstract: Communication is very much important for every community and radio communication is one of the easiest and simple media to provide information. The project represents the full duplex communication mode of FM transceiver (Radio + Transmitter). This paper describes on how to build a short-range FM transmitter using microcontroller. The paper also describes on how to build a FM radio receiver using micro-controller. Through the FM transmitter we can transmit our voice and any audio signal while through the radio receiver listener can listen any FM broadcasting channel. This project is based on KTMicro IC KT0803K monolithic digital stereo FM transmitter and Phillips TEA5767 radio receiver module. The quality of transmission and radio reception can be improved by Digital Signal Processing and Intelligent Tuning System. The heart of this project is Arduino UNO micro-controller which controls slave devices by Inter-Integrated Circuit (I2C) communication. The transmitter and the receiver both supports digital tuning and Phase Locked Loop (PLL) concept is used for recovery of the signals. The transmitter of this digital FM transceiver can be used for making announcements in schools, colleges, industries, hospitals, and other places using a condenser mic amplifier circuit and share music with the FM listeners using audio input port of the FM transmitter module. The radio receiver of this transceiver is used for listening any local FM broadcasting channel. It can be also used in specialized application such as local area network. For the construction of the transceiver it requires some small and low cost external equipment’s.
