Circuit Schematic AM Receiver using Transistor

Radio. - Here is Circuit Schematic AM Receiver using Transistor. A small, simple AM receiver project with only 3 transistors. This circuit can pick up medium wave stations in your area.

Description:

It can use general purpose transistors, and in this example there are 3 BC109C transistors. The schematic and BOM show a 200µH inductor and a trimmer capacitor 150-500pF, though these parts can be salvaged from an old AM radio, to preserve the directional nature of a tuning coil, and an adjustment knob (plate capacitor) that work well for radio reception.
