Two Stage FM Transmitter
After a two months we are back with a Simple and Working FM Transmitter Circuitry.This a two stage FM Transmitter which is in work fine and you can use it to transmit your signal over a long distance,Its work within 100 meters to 2-3KM.Frequency Range is 87.5MHz to 108MHz.For transmitting over a 2-3KM,its require a minimum 75cm antenna height.Increasing a antenna height will always give us a better range but 2-3KM Transmission is sufficient for smaller projects and increasing height will cause a circuit unstable so please keep your antenna height in between a 75cm-100cm.
Circuit Diagram:
Above circuitry contain all parts value.This is simple but very power full circuit for transmitting your signal over a distance,you can use this circuit in any projects or use this circuit for impress your friends.
Disclaimer: Build and/or use this device strictly at your own discretion as it is illegal to operate a FM Transmitter in most countries. The design is intended for controlled experimentation and to describe the principle of FM Transmitter only. The owner of this web site does not endorse any unlawful use of this device.
