How to make Wireless intercom at home with FM-transmitter-circuit

Basic Circuit

This is a Simple FM transmitter for an FM broadcast band at 110-120 MHz. BF495 is a small signal transistor for wide applications, but usually for AF. You can build a Simple FM transmitter with one BF495 transistor and several other component parts. A simple FM transmitter with only one transistor is often called a “bug”. This project is suitable for beginners in radio amateur, education, or hobbies. As an antenna, you can connect 150cm of copper wire.

You can make simple conversation from one home to another home in a distance of 300-500 meters. This transmitter generates a signal from 110 MHz to 120 MHz.
