I put a cat whisker detector on the single variable capacitor crystal radio as I hinted at in that video. Let's see how it works.
This is the radio I am upgrading:
"Crystal Radio--No More Variable Capacitor Designs? (4K)" youtu.be/0AvTO588SyU
WARNINGS:
- Never connect radio to any source of power. Not house current, nor batteries, nothing!
- Never use the radio during lightning storms.
- Never run an antenna over or near power lines.
- Disconnect antenna and put lead outside when not in use.
- Never ground to electrical items, plugs or similar.
- If you don't know, don't do it.
