The scheme of the detector receiver, proposed by **Prikhodko in 1926**, was called "Device for reception without tuning and grounding". In our time, with someone's light hand - this scheme became the **fork of Avramenko**. Who knows he will understand - 100% similarity, I wonder if Avramenko knows this?

The principle of the detector is this. As a result of tangency of the tip to the crystal, a contact is formed that passes a direct current, and does not pass the reverse. Many substances have the property of transmitting current in one direction. The main ones are listed below.
[Galen ](https://en.wikipedia.org/wiki/Galena) is lead sulphide
[Germanium ](https://en.wikipedia.org/wiki/Germanium) - a chemical element
Graphite - crystalline carbon
Carborundum - silicon carbide
Molybdenite is a sulfurous salt
Pyrite - sulfurous salt
Silicone - crystalline silicon
Chalcopyrite
Zincite - zinc oxide
