  POWER FULL LONG RANGE FM TRANSMITTER Circuit Diagram Power supply Using power supply stable DC voltage  5V  max. You can only use battery because battery is perfect for this circuit battery output doesn't any noise. Components Transistor BC547, Resistance 100 ohms, 4.7K ohms, 1K ohms, 27K ohms.   Capacitor 0.2uF, 0.5uF, 0.047uF, 6.8pF, 22pF.   Inductor 1uH. Condenser mic any. Resistance   Using resistance 100 ohme +-5% changing 1/3watt, 4.7K ohms +-5% changing 1/3watt, 1K ohms +-5% changing 1/3watt, 27K ohms +-5% changing 1/3watt. Capacitor   0.5uF this capacitor number 504 non-polar, 33pF this capacitor number 33 non-polar, 6.8pF this capacitor number 6.8 non-polar, 0.2uF this capacitor number 204. Inductor This part important part for any transmitter circuit, 1uH 5Turn 24SWG. Transistor   BC547  is an NPN Bipolar junction transistor. It is commonly  used  to amplify current. A small current at its base controls a larger current at collector & emitter terminals.  It has a tr
