This is one of a very few projects that I finished and actually worked better than expected. I did this about 3 years ago as a recreational woodsball player I wanted something I could communicate with the only other person I played with at the time. When a “big game” game was announced I knew yelling orders or spotting opposing players was going to give our positions away and have us warming up the spawn area. So here is my tutorial on making some ordinary uniden walkie talkies (wt from now on) into pretty cheap and easy tactical coms.
3.5mm Ysplitter (one in the picture is for 2.5mm jacks)
Some jb weld
Phillips head screw driver or whatever applies to your wt
First open up your wt case careful not to gouge the board or tear any wires. Find the two wires leading to the board from the speaker.Cut or desolder them from the board make sure you know where the wires are supposed to go. Set that aside for a bit and take out your Y splitter and cut closest to the connector as possible and separate the two jacks. Now with the soldering iron mark a groove next to where the two solder points for the speaker are now close the case with or without the pcb board if you can and carefully continue making the whole where the cord will come out of.
