This is one of the smallest FM Transmitters available which is presented as a construction project.
Some of the parts have been substituted to represent the microphone & antenna.
The 5pF capacity to the left of the coil should be variable from 2pF to 10pF(Fine Adjustment of 2Mhz). The Variable Resistor should be replaced with a microphone, and the ground+resister line should be replaced with the antenna.
