So I found a couple of CB waklie talkies, one 3 channel one 6 channel. They use crystals. I want to mess around with one of them and see what what it will do.
What can I plug in or make to plug in the RX crystal socket to receive something other than CB? Variable capacitor? Anyone have a circuit diagram of something that will work like one that I can use to make it more frequency agile? It's not for any purpose other than to see what it will do.
