Crystal radio with a LAN cable antenna
Germanium radios are easy to make and don't require batteries, but winding the coil can be a pain.
So I made a germanium radio that uses a LAN cable or flat cable instead of a coil.
Even though it's such a simple radio, it can receive broadcasts indoors under good conditions.
Components Used
1. LAN Connectors (2): 7810-8P8C
2. Earphone Jack: PJ-316
3. Polyvaricap
4. Terminal Blocks (2)
5. Flat Cable 8P Terminals (2)
6. Single-Row 3P Terminals (2)
7. Single-Row 5P Terminal
The LAN cable used is approximately 3 m long, with two wraps.
The flat cable is approximately 4 m long, with two wraps.
For either cable, no connectors are required if directly connecting to the board.
