Set of Devices for Radio Receiver
Product Code : EL-PLE-14992
Eduscope India is a leading Set of Devices for Radio Receiver
The Set of Devices for Radio Receiver from Eduscope India is a classic crystal radio receiver kit that demonstrates how radio waves can be received and converted into audible sound without any external power supply, part of our range of Physics Lab Equipment for hands-on physics education. Quick Answer: this kit uses a 140pF variable capacitor tuning circuit, a germanium diode (1N34) demodulator, a 1000pF filter capacitor, a 300uH coil inductor, and a vintage-style piezoelectric earphone (350 ohm) to let students explore antenna reception, tuning and resonance, and signal demodulation - electronic lab instruments India schools use for practical radio-wave teaching.
Construction and Specifications
The set includes an antenna to pick up incoming radio signals, working together with a tuning circuit built around a variable capacitor of 140pF, which allows the receiver to be tuned to a particular radio frequency. A germanium diode (1N34) functions as the demodulator, recovering the audio signal from the modulated radio wave, while a fixed capacitor of about 1000pF acts as a filter to remove any remaining trace of the radio frequency signal from the audio output. The tuning circuit is completed by a coil inductor of about 300uH, and the recovered audio is delivered through a highly sensitive piezoelectric earphone (vintage-style, 350 ohm) that can produce a faint but audible sound from the tiny amount of energy the antenna picks up. All components are assembled on a PCB for a stable, ready-to-use setup - the kind of reliable laboratory equipment school India physics departments use for hands-on electronics and radio-wave demonstrations.
