  • The Ultimate FM Transmitter  (Long Range Spybug)

    i made it and it works.my mobile's fm doesnot recives this,but a radio set gives a crystal clear sound upto 100mi did not used the trimmer cap,as it was unavailable,so i used a 12pf cap and did some calculations for the inductor turns, to set the frequency at 100Mhz.so when i turned it on the frequency was suprisingly really close to100Mhz.and by the way i built it on a copper clad... so thanx for the circuit and good luck to all
