Brand New Crystal Radio Design

 Uses a Spiral Printed Circuit Board Coil

Includes Radio, Amplifier, 8ohm Earphone and Alligator Clips

Here are the Amplifier and Radio SPECS...
----APMLIFIER----
This is the Newest LC Model with High Gain
Amplifier is same as pictured except New and Improved LC Revision Level
Uses a Low Cost LR44 or SR44 Battery
Battery IS INCLUDED
When Compared to the Best Piezo Element used with a Crystal Radio, my amplifier is 10X Louder.
 (See The Image in the Photo Gallery showing the Decibel Level as Measured with a Meter)

DO NOT ALLOW THIS AMPLIFIER TO TOUCH ANY METAL SURFACE-BATTERY MAY SHORT OUT OR PERMANENTLY DAMAGE THE ELECTRONICS

You can Use a Standard 8Ω (8 ohm) Mono 3.5mm plug Earphone with your Radio using this Amplifier

Includes a Quality Magnetic "transistor radio" Earphone and with 3.5mm mono mini plug.

The shape prevents the earphone from entering inside the ear canal.

Doesn't consume any power when the Earphone is UNPLUGGED

(You must Remove the Earphone from the Output of The Amplifier to Conserve the Battery Power) 

DOES NOT WORK WITH PIEZO OR STEREO EARPHONES

Simply Plug in the Earphone into the Output connector of the Amplifier and Plug the Input side of the Amplifier Into your Crystal Radio and it is ready to go.

DOES NOT INCLUDE ANY AMPLIFIER SCHEMATICS OR INSTRUCTIONS

----CRAYSTAL RADIO----

Crystal Radio has COLOR Matched Knob and PC Board
High Performance Germanium Diode

Requires a Piezo Earphone if you dont use the Amplifier (Piezo Earphone IS NOT INCLUDED)

Crystal Radio's will only work with a Piezoelectric (Piezo) Earphones. Cell Phone Earphones, MP3 Earphones, Transistor Radio Earphones WILL NOT work because Crystal radios only work with high-resistance earphones.

THIS RADIO COMES FULLY ASSEMBLED AND TESTED

Measures 54mm x 96mm and is great for Beginners, Survivalists or Advanced Enthusiasts

Double Layer PC Board Coil

NEWEST PCB Design allows you to connect an earphone to the Metal Screw Posts or use the 3.5mm phone jack mounted on the PC Board.

Built in Audio Jack


D311 Germanium Diode

Compact and Fully self-contained

Alligator Clips are included for Quick and Easy Connection

Instructions for getting the Operation Manual and Schematic will be provided after purchase

This Radio is Fully Assembled and Tested

Everything needed to listen to a fully functional crystal radio EXCEPT for the Antenna and Ground Wire

A minimum of a 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 possible . Search eBay or the net to purchase a "Crystal Radio Antenna" Kit or to make your own..
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.
Antenna and Ground wire IS NOT Included

This kit is a great way to get started in electronics and radio building. Crystal

Crystal Radio Kit is fun for both beginners and experienced enthusiasts

  8. With Leg Supports and Vinyl Feet
  9. 3.5mm Earphone jack is mounted on PC Board

If you live in a Fringe Location where AM Radio signals are poor or weak and you dont have room on your property for a 100 Foot long antenna, check out my eBay store for my "AM Medium Wave Crystal Radio Antenna RF Amplifier High Performance".
This amplifier Pulls in AM Radio signals like a Magnet.
