Am Radio Circuit Diagram. The antenna coil collects the mw signals present in the air. It is similar in principle to the zn414 radio ic which is now replaced by the mk484.
The circuit use a compact three transistor regenerative receiver with fixed feedback. Transistor q1 does the job of demodulation. The circuit is using only few components to make a good quality am receiver.
The circuit functioning is pretty basic.
