If you are going to experiment with these circuits, please note that I did not build them, and I am not able to help you with any details. If you have no experience in RF, I suggest that you choose the easy way and buy a ready-made RF module. Otherwise you can realize you have an exact copy of a circuit in your hand, still it doesn't work the way it should.Figure 1.
