Survive the End Days
Suffice it to say that with all the wires and old electronics lying around, making a simple
radio receiver is pretty simple. They can also be made to use power from the signal itself so
they don’t all need anything else to power them.
You will need:






Plastic bottle. It should be about three inches in diameter, and 5 to 7 inches long.
Shampoo bottles also work, but you will want to get the ones with thick walls, rather
than the thin flimsy ones. This will make it easier to wind wire around them.
About 50 feet of enamel coated magnet wire. Most common gauges (wire diameters)
will work, but thicker wire is easier to work with, something like 22 gauge to 18
gauge. You can also use vinyl coated wire, which in some ways is easier to use than
enamel coated wire.
A Germanium diode. Most stores that sell electronic parts have these. They are called
1N34A diodes.
A telephone handset. You listen to this radio just like you listen to the phone. If you
have an old telephone sitting around, or can find one at a garage sale, you are set.
A set of alligator jumpers. You can find them anywhere electronics parts are sold.
About 50 to 100 feet of stranded insulated wire for an antenna. This is actually
optional, since you can use a TV antenna or FM radio antenna by connecting our
radio to one of the lead-in wires.
Use a sharp object like a nail or an ice pick to poke four holes in the side of the bottle.
Two holes will be about a half an inch apart near the top of the bottle, and will be matched
at the bottom of the bottle with two more just like them. These holes will hold the wire in
place.
Thread the wire through the two holes at the top of the bottle, and pull about 8
inches of wire through the holes. If the holes are large and the wire is loose, it is OK to loop
the wire through the holes again, making a little loop of wire that holds snuggly.
