    Default Crystal radio without an antenna

    All of the circuits that I found for crystal radios have you connect it to a long wire for the antenna or to a cold water pipe for a ground. Is there any crystal radio circuits that don't need a long antenna?

    Long antennas look messy.

    No power, no amplification, just a germanium diode and headphones would be so much fun and portable too.
