    Dear all,
    I regularly build little circuits that I find online, and I find myself running out of options. I especially want to build radio jammers and broadcasters, but I don't have every kind of diode, inductor and transformer in the world. If you could give me any links that would help me to understand how a radio broadcaster works, it would be greatly appreciated!
    thanks, The physics newbie

    Jamming radio transmissions will quickly get you in hot water. It's illegal to do so.

    You can also get in trouble really quickly building transmitters that interfere with commercial, police, fire, aviation or military communications, or outside of any amateur bands that you are specifically licensed to broadcast on.

    It IS possible to build transmitters and receivers, but you must do so in a legal manner.

    I suggest that you get involved with the Amateur Radio Relay League or a local ham radio club; they can provide a great amount of information while keeping you out of hot water.

    If you are looking for schematics on an cell phone jammer, you need to go here:

    This was also mentioned in IEEE Spectrum magazine about a year ago.

    Build at your own risk.
