    Some electronic parts and knob designs or colors may vary from photos but are always improved equivalents.
    NEW Design allows you to change the main Coil total inductance with the press of a switch !!
    Press yellow button to
    reduce inductance by as much as 50%, press again for full inductance
    The inductance is locked/latched and will hold until you press the pushbutton again
    Assembled and Wired Ultimate Professional Grade Crystal Radio with Piezo Earphone and a
    High Performance Coil
    Engineered Quality Coil
    This is my Best Coil I have designed
    Designed to improve Signal Strength and Audio Volume.
    Great Radio Backup for when a Power Failure happens.
    Instructions are in the Picture Gallery in JPG format with this listing,
    If you are unable to view and read the images, the instructions for getting the files by PDF will be included with the radio when you receive it.
    Simply Connect the Included Earphone and attach an Antenna and Ground and it is ready to use.
    (Antenna and Ground Wire Not included)
    A minimum of a
    30-50ft long outdoor Antenna Wire is recommended.
    The best configuration for a crystal radio antenna is to run the wire horizontally between two electrically insulated supports as high off the ground as you can get them
    .
    The reason you need a good length antenna is because the more antenna you have, the more power your set will receive, and the louder it will be.
    This Radio permits easy changeover when experimenting with Different Diodes, Earphones or Coils because of the threaded Knurl Nuts used in the unique design.
    This is a must have for any Survivalist to keep in your Survival Kit or backpack if the power goes out and to be able to tune to a radio station.
    The components can be disassembled from the platform and the base can be stained and finished to your liking.
    Crystal Radio Set Kits are sometimes called Xtal Radio Kits and Crystal Diode Radios.
    Listen to radio using only the power in the radio waves
    This is a must have for any Survivalist to keep in your Survival Kit or to keep at home if the power goes out and to be able to tune to a radio station.
    ALSO INCLUDES A PIEZO EARPHONE with an integral 3.5mm Male Jack.
    An Earphone Female Adapter Jack is already Installed to the Radio. Just need to attach an Antenna and Ground and it is ready to use.
