Try building an FM crystal set. It can be done (as many hobbyists have demonstrated) but it will only receive very strong and local signals. Unlike an AM crystal set which can hear stations many hundreds of miles away.
- iasay 4y agoI’ve built AM crystal sets before back in the 80s. Fine if you have the space and materials for a high up long wire antenna or something. But absolutely hell if you have any local noise sources. I actually had a large inverted V trapped dipole on my property which could be persuaded to tune up on AM broadcast with some effort and pick up all sorts. But ugh you need a decent noise blanker or nulling device unless you live in the middle of nowhere. Add a couple of transistors and some discrete components and you can build a fairly decent FM receiver instead of a crystal set which performs adequately with a couple of metres or so of wire taped to a bamboo garden cane.
