MW Regen-Superregen Receiver Using 2 Voltage Regulators
This unusual circuit uses a 78L05 series regulator as a regenerative receiver and a TL431A shunt regulator as an audio amplifier.
Using only a standard MW ferrite rod inductor no external antenna or ground are necessary.
The circuit is even more unusual because in superregenerative mode it is capable of receiving and separating AM broadcasts 40 KHz apart.
