    "Crystal" radios were kinda interesting. If near
    an antenna you didn't even need a battery. Don't

    (I think the definition of a crystal radio is that it had no amplifying devices, so needed no battery; it could only _get_ strong stations,
    unless a big aerial.)

    I once saw a schematic for a radio with two tuners. You tuned one
    of them to the strongest local station, whose signal was rectified
    and used to drive an amplifier for the other tuner, that tuned the
    station you actually wanted to listen to. Still no battery.
