One transistor fm receiver. However fewer components also means a few compromises involved here the receiver requires a large metal base for grounding the unwanted signals and for keeping the noise factor to the lowest and also this. This circuit is suitable for learning only.
Transistor bf495 t2 together with a 10k resistor r1 coil l 22pf variable capacitor vc and internal capacitances of transistor bf494 t1 comprises the colpitts oscillator.
The output is connected to earphones you need an amplifier circuit if you want to listen the radio with a loudspeaker. The output is connected to earphones you need an amplifier circuit if you want to listen the radio with a loudspeaker. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The frequency mainly depends on the positioning and the values of the inductor c1 c2 and c3.
