I have received a number of emails regarding schematics for crystal radios. After about the third email, I figured that I may as well put one on my page. So here it is. The circuit is very simple with only 5 parts, but performs very nicely when used with the right size antenna.

1. C11Tuning Capacitor (See Notes)
2. D111N34 Germanium Diode
3. L11Loopstick Antenna (See Notes)
4. SPKR11Crystal Earphone
5. MISC1Wire,
6. Board,
7. Wire For Antenna,
8. Knob For C1
