Building a crystal radio without a battery—many might not believe it will actually work. However, if you have ever built one, you would have used either a manually constructed detector or a germanium diode.

Would you trust a directional antenna like this for satellite communication, or would you build something different?

Homemade Single-Tube Armstrong Regenerative Shortwave Receiver (1930s-1940s).
The receiver uses a vacuum tube and a feedback coil called a tickler coil to amplify weak signals.

Homemade Single-Tube Armstrong Regenerative Shortwave Receiver (1930s-1940s).
The receiver uses a vacuum tube and a feedback coil called a tickler coil to amplify weak signals. The tickler coil is mounted inside the main tuning coil and can be rotated using a front-panel knob. This adjusts the feedback, allowing the operator to control the receiver’s sensitivity and tune in distant shortwave stations.
