Simple FM transmitter Circuit 1.500 Meters

Circuit extremely simple drawing made ​​with PCB antenna coil bobbin not need to use additional circuit instead of one transistor bc547’s bf will be equivalent series circuit with transistor think will work more efficiently.

5-inch wire antenna used for radio antennas can be sold in or outfitter fm transmitter circuit works with a 9 volt battery. LC oscillator tuning signal coming from the microphone via a decoupling capacitor on the base of the transistor. Everything you are describing is true, because I have the microphone built and tested. You said I was trying to reach with ordinary FM receiver, so who has a sensitive range is even greater.
