    What does a AM circuit do?
    Is there anyway to jam an AM transmission?

    it varies the power envelope of the RF energy.

    Think of it as a very fast light bulb dimmer. The power will vary from no light to very bright. The act of turning the dimmer knob would be the 'modulation'. The brightness of the bulb would be radiated RF power.


    To jam AM you have to 'swamp' the reception area with a HIGHER power steady state RF signal. One with no modulation or with a source of pink noise to modulate the jamming signal.

    It's fairy easy to do, but carries serious consequences if that signal is a licensed transmission. The FCC is pretty brutal about penalties.

    How would you jam a satellite transmission that uses this type of FM?

    I do not think this line of questioning needs go any further. What you are suggesting is illegal.
