The circuit use a compact three transistor regenerative receiver with fixed feedback. The circuit displayed below is a tunable am signal trap circuit which can be controlled to retrieve unwanted am signals and channel the remainder to the receiver. Easy to build using only two integral circuits ic.
Only a few simple parts are needed to pick up am radio waves.
The demodulated signal will be available at the base of q1 this audio signal is coupled to the base of q2 for further amplification. You can easily get these components from an old. The coil l1 and variable capacitor c1 forms the tank circuit.
