Gentlemen:
I am including the name of the Company
that can provide those interested with
all types of telephone devices as well
as info. They also have two correspon-
dence courses that I believe are the
best (only) of their kind.One is a
telephone engineering course-how to
make your own clandestine devices.
The second is a "spy" course. You §&
your readers will flip over their
catalog. Cost is $1 deductable from
any purchase-anhd well worth it.

RECEIVE FREE LONG-DISTANCE CALLS!
Now you can receive calls at no charge to the caller,and anyone, even a
child, can convert their phone to do this in less than 30 minutes. You
only need two parts: A "single pole,single throw toggle switch" and a
"10,000 ohm, 1/2 watt, 10% resistor" .Hardware stores carry switches with
two wires already on them, and these are convenient to use. The resistor
can be bought for 20¢ at a radio-tv supply or electronic hobbyist store,
such as Lafayette Radio. If you can't find a switch with wires already on
it, get oné with screw terminals so you can easily attacn on wires.
Cut two pieces of wire at least 6 inches long.
Strip off the insulation
1/2 inch from each end. Attach one wire to each of the two switch screws,
and you now have a switch with two 6 inch wires connected.
Turn your normal _djal phone upside down and unscrew the two screws, and
remove the case.
You wi
now see a small metal box with 16 screws on top
and wires connected to them. Locate the screw marked "F" using our diagram
and loosen it. Wrap one of the resistor wires around it and tighten the
screw. Loosen the "RR" screw and remove the green wire. Then wrap the other
resistor wire around the "RR" screw along with one of the switch wires.
Tighten the "RR" screw and be sure the wires only touch the proper terminals
and no others. Finally,wrap the remaining switch wire around the green wire
you just removed and wrap the two up tightly in scotch or electrical tape.
Close up the phone, running the switch wires out the side or rear of ‘the
case. Hang up receiver and get a piece of tape and a pen. Pick up the phone
and flip switch to the position that gives you a dial tone. Using tape, mark
this position of the switch "Normal". Now flip the switch to the other pos-
ition and the dial tone should stop. Mark this position of the switch "Free".
If you don't get it to work right, check your wiring for a break or a wire
touching a nearby screw inside the phone.
Leave the switch "Normal" for everyday use. When your frieuds call, quickly
1ift and drop
receiver as fast as
you can. This is very important that you
do it quickly. This should stop the rings. If not,do it again. Then switch
to "Free’,pick up the phone and talk. Keep all calls as short as you can,
always less than 15 minutes. At end of call, hang up, then switch to "Normal".
If the call is local, switch to "Normal" immediately or you may be cut off.
Your friend can call right back, so the shorter the call the better it is.
TOWARDS REAR OF PHONE
HOW IT WORKS
.
When you call someone long distance, you are billed from the moment they
_
answer. The phone company knows you answer when a certain amount of electric
current flows through the phone. However, the resistor cuts down the amount
of current below the point of billing,yet lets enough go by to operate the
mouthpiece. Inside the phone, connected across the F and RR terminals, is
a capacitor, a device which allows more volume for your voice without using
any more electric current.
.
.
Answering the phone normally for a fraction of a_ second stops the rings,
but does not let enough current flow to start the billing. If you answer
normally for even one full second, however, billing will start. Therefore,
hanging up and switching to free will cut you off.
To render the device ineffective, the phone company would have to spend
billions of dollars and nany years of changing the country's phone systems.
Using this device is illegal in some places, and we strongly urge you to
inspect all phones you see for the device. If you see it, rip it out and
eat it immediately.
By the way, you cannot use an ext....10n phone during a free call unless
it too is modified and the switch is in "Free".

If you come across a pay phone minus
the cash box(large gaping hole in
front) put hand in hole find small
square hole in top rear of large

know which one)in the hole and feel
for button(feels familiar,right-

liberated thru hole. There's more

It's a great way to get some bread.

Dear YIPL,
Here is a tip for people who are
going across country. Take along
phone numbers on both coasts that
won't. answer. Whenever you stop
near a pay phone tell the operator
you want to call the further away
of the numbers, and put the coins
in the phone. After she returns the
money, insist that it didn't come
back. Give her the address that
you're going to, and when you get
there you'll have a lot of refunds
waiting. I also think its a good
idea to dial operator whenever
you're near a pay phone and say
that you lost a dime and already
made the call, so would they send
you the dime. Then select a name
at random for them to send it to
from the phone book. -Bill
