Fm Transmitter (200M)

This is a Fm Transmitter circuit.This circuit can Transmit signals up to 200M.L1 is 1mH inductor.When I built this circuit I used PCB.






Note

# Make inductor with the support of this formular L = (d²n²) / (18d+40l)

L is the inductance of the coil in uH
d is the coil diameter in inches
l is the coil length in inches
n is the number of turns


# Use 12V power supply for this circuit.

# Build this circuit on a PCB
