Set of Devices for Radio Receiver

Quick Answer: The Set of Devices for Radio Receiver is a classic crystal-radio-style demonstration set that lets students explore basic radio-wave reception without any external power source, a hands-on item of physics lab equipment India educators use within our laboratory equipment school India range for teaching electromagnetic signal reception.

Construction and Specifications

The set includes an antenna for signal pickup, a tuning circuit with a 140pF variable capacitor and a ~1000pF fixed capacitor for tuning to a chosen frequency, and a germanium 1N34 diode for demodulating the audio signal. A ~300µH induction coil and filter remove remaining radio-frequency traces, delivering sound through a sensitive 350Ω piezoelectric headphone that produces audible output from the tiny energy the antenna captures. Mounted on a PCB base, it needs no external power, making it ideal for teaching electromagnetic signal reception.
