to find the schematic

Using one NPN transistor, one resistor, a handful of capacitors, and snippets of wire, you too can build this radio!
It can tune around the US FM broadcast band, the aircraft band, and the lower VHF TV channels (audio only, of course!).

It is basically a regenerative receiver, with a very weak audio output, hence the necessity of
amplification. The parasitic capacitance of the transistor apparently plays a large role here, though I do not understand it well. Care should taken towards the placement of the parts and lengths of the wires used, as this will change the tuned frequency!
