In this project I will demonstrate how a RF FM transmitter works and how this principle compares to the older AM. I will also show you how to build a simple and crude FM receiver which can even sometimes let you listen to your favorite radio stations. Let's get started!
The video gives you plenty of information about how FM and AM radio signal communication works and how the receiver circuit performs. I will present some additional information for the receiver in the following steps.
Here you can find a parts list with example sellers for your convenience.

You did it. You just built your own crude FM Receiver and learned something about RF communication.
