I am trying to receive an audio signal within this range of baseband frequencies. I don't think it is AM or FM signals - these waves are longwave radio signals and fall beneath the range of AM frequencies (540 - 1710 khz). SO neither AM or FM. Specific instructions would be appreciated :).

I am trying to build a radio to receive a 200 hz - 20 kHz signal. Can anyone give me a starting point as to what specific parts I would need (breadboard, operational amplifier, transistors, resistors, antennae, etc..)? The signal frequency is the most important thing for this project. Thanks...
