    Note* if you want to improve range just add More voltage like 12 Volts it Will Make the range go from 1x to 3x

      Not that much bro, instead of using higher voltage we can use RF amplifier which we can make with only 3 component:
      1 transistor,1 resistor and 1 inductor which can make the transmitting range longer and also increase the output power but dont raise the output put to much because the police will find you

    I have a question: as we know, quartz cristal oscillators don't permit a deep frequency shift (as the 75kHz ones, existing in commercial FM stations transmitions off), wich are possible by the LC oscillators applications only (whose frequencies are stabilized by a PLL synthesizer, that has a quartz cristal oscillator for reference); so, is this design of yours an amplitude modulation one, even tuned by a FM receiver, isn't it? And I think that this is too likely, just because your oscillator doesn't have a varicap diode for the modulation - by the way, is it (the audio) clear and deep on FM receiver's the speaker?
    Now, I just have a suggestion: take off the RF signal (20MHz, whose fifth harmonic is that is being tuned by your FM receiver, in 100MHz, in this video), to the antenna, from the colector (first electrical terminal) of the transistor, in instead of the base (second one): if you do it, the RF sign will be stronger on the FM radio receivers near your small transmitter!
    Thank's!

    How are you getting 100mhz from an oscillator vibrating at 20mhz? What's doing the multiplying times 5 to bump it up to 100mhz?
    Is the antenna tuned specifically for 100mhz or is it bent to receive all FM radio frequencies?

      @DavidALovingMPF102 3 ปีที่แล้ว +1

      20 mhz is the fundamental frequency, first harmonic is 40 mhz, (20 X 2 =40, 20 X 3=60, 20 X 4=80 and 20 X 5= 100mhz) 4th harmonic. If more powerful, it would need some output filters to suppress those harmonics.

      @@4fifz416 One oscillator. Google rf harmonics. Square waves can produce more harmonics, so I am told, than a nice sine wave. The goal is to make an oscillator that produces a nice looking (on scope) sine wave. Less distortion. One great experiment is to build a circuit (function generator) that makes a triangle, square and sine waves. 8038 chip or LM324 can do it. Now, send those wave forms, one at a time to a 386 audio amp. You will hear the difference. A good sine wave will have a pleasant tone, almost bell like or musical instrument, at low frequencies. The square wave will not.

    adicionando um transistor mais potente em uma nova etapa, este transmissor ficaria muito melhor.. com alcance na ordem de 500 a 1500 metros ( _dependendo do transistor e sua correta polarização_ )
    Já vou começar a projetar o meu . Só que vou usar uma etapa pre-amplificadora de audio de entrada , pois pelo que percebi no vídeo,, tem portadora porém o áudio está bem fraco. Em minha opinião falta uma pre-amplificação na entrada. E para a saída de rf eu pretendo usar algum BD*
