schematic help

dirtdiver

Hi everyone,

now my question isnt arduino related , but i couldnt get the answer somewhere else so i thought that some of you guys might know the answer.

OK so i have a schematic for an FM jammer/transmitter - its both as it jamms the signal by transmitting nothing.

I want to change that nothing to a something (and i know for a fact that its posible with that schematic)So I need to hook up a 3.5mm jack somewhere on that schematic, my gues would be to connect it between the 0.01uF cap and GND , but am I correct? if not do you know where am i supposed to connect it to?

Again sorry that its not arduino related but any help is highly appreciated!

    I take it you where going off this site.

    That is designed as a jammer only. All it has to do is flud the airways with noice to block out any other signal on the set frequency. Its only half the circuit needed if you actually want to transmit a decernable audio signal. The circuit needs to have 2 transistor in order to amplifiy the signal from teh microphone enough to get a good audio signal through to the receiver. The circuit your working with right now at best could transmit mourse code using key wired between ground and the negative lead of the capacitor. You can try putting a mic there but like i said you will have a hard time hearing it through a radio.
