The circuit may work but it relies on a “Q-factor” from the coil and capacitor in the tank circuit to produce a high voltage. This high voltage gives the circuit a good range. Firstly the coil and capacitor should be near each other. The coil should not have long leads. and a 22n capacitor should be across the supply to give the circuit better performance. The value of C2 is too high. It should be 10p. The coil should be 5 turns. The electret mic should not be connected directly to the base of the transistor.
what about fm receiver .you haven’t talk anything about fm receiver
