DIY Guide: Learning How Frequency Modulation Works in FM Transmitters
An understanding about how frequency modulation works is important in the VHF or UHF FM (understanding the FM 
transmitters). The following article will guide you to both FM (frequency modulation) and PM (phase modulation) methods which will permit reception of the transmitted energy by an FM receiver.
What you will find in this article are sections such as how to create an FM signal, the difference between FM and PM, FM sidebands, Audio for FM modulators (examples of oscillators used for FM and PM generators in a crystal-controlled system circuit, simple audio channel in an FM transmitter), and how to setup for an amateur FM transmitter.
