This is a Fm Transmitter schema.This schema can Transmit signals up to 200M.L1 is 1mH inductor.When I built this schema 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 schema.
# Build this schema on a PCB
