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.
