The LM386’s potential as a radio receiver was discovered a number of years ago while investigating anomalous behavior in a receiver that used one of these devices. The sound quality of this receiver is excellent when using Walkman headphones. This is a very simple FM receiver which build based on one transistor only. Single Transistor Radio Receiver Circuit - Homemade Circuit Projects. Variable resistor. The most common form of double balanced mixer is the diode double balanced mixer. Close-up. Regenerative Receiver Links. Wrap the first Magnet Wire around a thick pen or a size AAA battery. But I build the circuit and hook the output to a high impedance headphone, no radio reception whatsoever. The overall perfor- mance of this circuit equals that of many superhet designs, yet it has very Figure 1. shows the schematic diagram for a very simple one-transistor audio amplifier stage that is useable by itself or with a crystal detector radio.This amplifier has only five components, … The amplitude of the circuit is to use the generator Frequency circuit technique used...
