Hi all,
I have been trying to find circuits to make my own DIY walkie-talkie. Referring to video at here, the Jumper wires(yellow), is it just a wire connection from 1 to 2 ? If so, why need Jumper? Does this circuit works by converting our audible frequency sound to higher frequency sound (Humans cannot hear) ? Or, if someone has build these amazing walkie-talkie before, can share some schematics that is the simplest and easy to build which has walkie talkie working via FM transmitter and receiver? I know there is some WIFI version but it only works with WIFI so I don't really want it.

Thank you for reading and have a nice day

 

Walkie-talkie is a very difficult DIY project, any "simple" circuit is not going to work worth a darn.

Unless you are ready for a really challenging, several month learning project, I would skip this idea.

 

Why do you want to make your own walkie-talkie when they are readily available off the shelf (besides the fact that there are strict regulations governing the operation of RF transmitters)?
