Figure 4 This schematic shows how to use the LM386 as a medium wave regenerative receiver. If the regeneration control is removed, the circuit becomes a Colpitts oscillator. The two required Colpitts ...

A small, simple AM receiver project with only 3 transistors. This circuit can pick up medium wave stations in your area. It can use general purpose transistors, and in this example there are 3 BC109C ...
