Lots of people are requesting walkie-talkie and RF remote control schematics, so here is some. Building these circuits needs special equipment and expertise in RF circuits. 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....Go
