This paper addresses the design of FM Transmitter, Tx and Receiver, Rx based on frequency modulation operating in the range of 88MHz to 108 MHz which is the radio frequency range. The individual circuit block was designed and simulated. Further it was tested using breadboard before it was soldered on PCB.The proposed FM Tx and Rx were evaluated in free space by placing at the distance of 10 meter after fabrication. The designed Tx send the signals and received by Rx at 10 meter. The additional features added were LCD display of frequency and power circuit for both FM transmitter and receiver.
