    I was actually thinking about to learn how to make a radio out of basically scrap, but I REALLY depends on the quality of scrap you have. A crystal radio might be possible but that ear piece is probably hard to get/build

      You basically just need to be able to make tunable oscillators and amplifiers. You need to find inductors, capacitors, and transistors. The hardest part would probably be finding manually adjustable inductors or capacitors these days. I guess maybe you could make your own tunable inductor by coiling the wires around a core yourself, then stripping off bits of the outside edge of the wire and selectively shorting it out. Adjustability is imperative, to make your radio’s frequency tunable, so you can get them all on the same frequency. Oh, and you’ll also need some buttons/switches, speakers, microphones, and batteries. All of those should be easy to find, except maybe the batteries as time goes on.

      But, really, a radio is fundamentally a very simple device. It shouldn’t be that hard if you know what you’re doing. And there will be literal mountains of scrap machinery that’s full of electronic components you can salvage.
