How to make a 315MHz transmitter.

In this video I am showing how to make a 315MHz transmitter circuit using simple electronic components. This circuit can be use for any remote control appliances such as rc car, RC truck, remote controlled toys , rc helicopters etc. I explained every details and shows all details of the circuit and PCB.

Warning Some countries are required special permission from their authorize departments to use or test this kind of RF devices. Therefore it is your responsible to get such approval based on your country.
