Wiring And Schematic

This is a Simple FM transmitter Microphone Circuit Diagram. In this schema utlise for An op-amp IC (741) amplifies the audio signal from MIC1, and R12 controls its gain. Audio is fed to the oscillator schema Q1 and related components. D2 is a varactor diode. Audio fed to D2 causes FM of the oscillator signal. L1 is 3 turns of #18 wire. The antenna is a 12` whip.
