    Hai guys
    Im a newbie in electronics.
    So I intend to build a device which is used for communicating through radio frequency.
    I got this idea from the movie Die Hard 4.0.
    In the movie, a hacker can communicate thru the frequnecy 666.

    So is ther any way like that through radio frequency to communicate?

    PLEASE HELP!

    You've heard radio, or seen television, right?

    OK, so your answer is that yes, you can use radio to communicate.

    I feel that I'm not understanding your question.

    You buy/build/borrow something which can transmit at the same frequency that a receiver (which you have also bought/built/borrowed) can receive.

    An example is a (pair of) walkie-talkies.

    Hello,

    Here is a great video on youtube on AM transmission and how to build a crude transmitter:


    That uploader's other videos are also very good

    As for a receiver, I am actually building one for myself! Look up foxhole radios. They are simple to make, although I am still having trouble tuning it, and there are many kits available online if you don't want to make it yourself. Actually, you could just use your home stereo if you don't want to build one.
