CRYSTAL's voice, still charming after 100 years

I build many different radios and related things. Use these headphones with very basic crystal/foxhole sets. Normal price, decent sound and no problems with any of them. This radio is 3D printed by FLASH FORGE (seen on AMAZON) and uses a coil and germanium diode also from AMAZON. Good ground, sufficiently long antenna (both with the same cable as the coil) and you can hear local AM broadcasts. No matter how much I'm doing, it's always fun when the noise softens and the voice or music is clear. And it's powered solely by the radio waves themselves.

Pros

Dope 🔥
