RF component of Simple AM Radio Receiver Circuit Modulated RF voltage developed through the tuned circuit is given the transistor (Q1) 2n2222 through the coupling capacitor (C1) 0.2uf. After feeding, Q1 amplifies modulated signals and demodulates the signal. In the collector terminal of Q1, the RF component is shorted to ground through the capacitor (C2) 470pf. Amplification of the Audio and regeneration In the circuit, Q2 is separate for audio output. At the emitter of Q1 (NPN transistor), a portion of the signal is fed back to  L1. The amount of this feedback is adjustable with a variable resistor (VR1). The speaker is connected to the collector of Q2 for the output of amplified singles through C4. The capacitor C3 is charged through Q2 and feed Q1 through Resistor (R1). The voltage through C3 is fed back as an automatic gain control to the base of Q1. This circuit can be used as a final project for electronics students. For more detail, please visit Application of AM Radio This AM Radio Circuit can be used for the following purposes.
