What's the simplest ore radio to do?
2AP9 diode is a 600 ohm above the earplug foil 65 cm long 2 cm wide kraft paper a 70 cm long 3 cm wide and 3 meters to a copper wire wrapped in kraft paper in electric wire and copper wire tin foil wrapped in kraft paper outside the 3 meter long wire peeling exposed around 1 meters above the other foil one end is connected with the grounding wire and radio headset diode parallel diode cathode copper wire electrode tap water pipe is connected with a tap water pipe line lamp is very simple and don't pay attention to the leakage
The most simple ore radio, a three meters above the overhead antenna, a ground wire, a 2AP9 diode, a high impedance diode in parallel with the headset, headset received two world online, only listen to the strongest local Taiwan, if there is more than a strong one mix together.
The antenna metal wire, metal ores and stylus, wooden box, 8 ohm headset, etc.. (ore radios don't need electricity.)
