New Design Crystal Radio with Piezo Earphone and Alligator ClipsTHIS RADIO COMES FULLY ASSEMBLED
Knob designs may vary from picture, but are always improved equivalents
This Model is designed with a Large 350uh Air Coil
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 Push 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
Designed using an Assembled and Wired Printed Circuit Board Radio with Piezo Earphone
High Performance Coil with Included Alligator Clips
Engineered Precision Wound 350uh 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.
The instructions for getting the Schematic and Instruction 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 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 sanded, 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.
INCLUDES A PIEZO EARPHONE with an integral 3.5mm Male Jack Mounted to the Circuit Board.
Just need to attach an Antenna and Ground and it is ready to use.
