RF bugs connect their positive and negative leads to the phone line or phone's circuitry. They convert the electric pulses from voice on the phone line into radio waves that can be received by any device listening to the same frequency
I got this information from a website. I want to know how to build this kind of RF transmitter. I want to use it with a mobile phone, so instead of the loudspeaker i will connect the positive and negative leads to the circuitry. I have a small earpiece that can receive radio waves . Does any one know if it is possible to make a FM transmitter like this one: http://www.youtube.com/watch?v=lIyyMVsk2WA and instead of the mic, i solder 2 wires and connect them with the phone ??
