How to make a poket radio(circuit)

Pocket radio diagram

Needed

• BF 494 transistor  T1, T2.
• Variable resistor.
• Variable capacitor.
• Inductor coil.
• Lm 386 IC

Follow this diagram and do it,

Then follow the instruction

:Initially connect the circuit as shown in the figure.

:Connect the power supply to the circuit.

:Now press the switch.

:Now adjust the frequency of the circuit by varying the trim pot (variable capacitor) of the tank circuit.

:Thus the circuit starts tuning to the nearest frequency.

:When the frequency of incoming signal is matched sound can be heard through the headphone or speaker.

:Now tune the circuit to the  another frequency using tank circuit.

:You can listen another sound incoming at that particular frequency.

:Adjust the variable resistor to increase or decrease the volume.
