Simple Pyro RF Transmitter (27 MHz)

An Overview Of The Simple Pyro RF Transmitter (27 MHz)
           Through this article we looked at the fundamental building blocks of a simple rf transmitter that operates at 27.145 MHz. It used a carrier frequency mixed with our actual signal to produce a continuous wave that we could transmit to a receiver. While that sounds simple on paper, building it using our imaginations required some large steps in understanding and testing.


What To Do Now
           The obvious choice is to go make a receiver for this transmitter. Since we know the carrier frequency, the expected signal to receive and how powerful our transmitter is, we can start building a receiver that can use the data coming in do 'something' wirelessly. How about starting off with blinking an LED? After that we could look into actually transmitting data!


Conclusion
           The purpose of this article was to explain how to build a simple rf transmitter. In that goal we have been successful. However, please be realistic in the capabilities of this transmitter. It is 10mW and built using all thru-hole parts on a home-made PC board and this means it will work, but never as well as your cell phone. However, now its time to look into building a receiver to pair with this transmitter!
