    Hi:

    Which stores sell 2.5 GHz AM radio? I want to hear the sounds resulting from demodulating an amplitude-modulated 2.5 radio wave.

    I choose AM because it is more likely to be affected by EMI/RFI, than FM. FM usually just hisses. On an AM station, there is usually more impressive sounds -- such as the tones from outer space.

    Where can I find a 2.5 GHz AM receiver for the above purpose?


    Thanks,

    GX

    Are you trying to receive somebody's wireless surveillance system, or Wi Fi?

    I don't think either are AM though.

    That is a band allocated for computer wireless networks.

    My only interest in this is to listen to the disturbances from outer space. I chose the UHF band because the ionosphere lets those frequencies through. At lower frequencies, the ionosphere blocks.

    I see.

    How do you expect to get the amplification, sensitivity, and signal to noise ratio you would need?

    Do you understand what you are asking for?

    Then...

    How are you going to separate it from all the terrestrial noise?

    Why do you expect it to get AM at that?
