TAP No. 19 - Snoop Light, Taping Fortress Tones

Reports Northwestern Bell removing bells from pay phones and quotes AT&T chairman John D. deButts’s rosy public statements against Security Letter editor Robert McCrie’s more skeptical read. ‘Monkey Warfare’ catalogs methods for defeating parking meters (fake coins, magnets), while ‘A Red Box in Every Pot’ explains recording pay-phone coin tones on cassette tape for reuse without owning a box. Includes a ‘Snoop Light’ circuit for detecting picked-up extensions during a call, and ties AT&T subsidiary Chesapeake & Potomac Telephone to the Watergate bugging operation.

JUNE 1973
no.19
Northwestern Bell Telephone is starting to take the bells out
of pay phones to prevent, they claim, collect calls to pay
phones and "signal calls" where people hear their phone ring
once and call back to a pay phone. Thus, if you have a life-
or-death situation where you must be called back, you're
out of luck, So much for the argument that "pay phones are
a public service"... Robert McCrie, editor of Security Letter,
a anti-ripoff newsletter showing companies security methods,
‘s plugging YIPL for business execs. He calls us "a bunch of
nuts" and puts in our address with the warning "don't use the
office address" (of their company). Security Letter, 475 Fifth
Avenue, N.Y.,N. Y. 10017. Use an office address-you're
writing for a company, remember. Say you want to subscribe
to Security Letter, ..John D. deButts, chairman of AT&T, in
U.S, News and World Report, (Tomorrow's phone service-
Why it Will Cost More) comes up with some outrageous
state-
ments like "a public telephone is a public service", "Service
in New York City today is good" and"'we ‘had always felt the
Bell System companies were well out ahead in the fairness
of our employment practices", Also"People don't visualize
the uses for Picturephones". George Orwell did in 1984, but
deButts doesn't mention bugging or privacy at all. Another
item of interest: "Do you have 2 telephone listed for John D.
deButts at 200 Z. 66 St?...
Yes, that is 421-2277"... "In
Kansas City, the existence of just such an arrangement be-
tween the telephone company and the chief of police was re-
vealed". That's 2 quote from Monopoly that YIPL printed in
issue #1, Well friends, we all know how big corporations
often exert political pressure to help their friends into office,
don't we? Nixon just named Clarence M. Kelley, the police
chief of Kansas City to be Director of the Federal Bureau of
Investigation, Maybe all those wires will go to a little box on
Clarence's desk...
MEAT!
Several of you have written about-meetung other phreaks
in your area, Some feel that this would invite infiltration,
and that meeting at electrical supply stores is probably a
lot safer. This way you could see who you meet before you
meet them. Then again, you don't know if they're in the
"field" unless you ask. Others have said that if another
phone phreak convention is held, that would be the ideal
place. Or, again, YIPL could receive requests to meet
other phreaks in your area, and send pairs of people the
name and number of each other simultaneously, from rea-
ders whom we feel are cool. If you send in, be patient. We'll
try to match another reader, only one, for each request.
HOT FLASHE
A friendly Pa Bell worke? says that though most telephone
kompanies use the amount of resistancé in
ringing the bells
on @ line to determine the number of phmes connected, in
some (college) towns they run spot checks of total line re-
sistances that detect phones even with the bell disconnected,
So a good policy is to
make up a one-line "conference" call
maker (YIPL #1)and to leave the switch in the center-off
position when not in use.

ticated. It comes with different slots on the side for different
coins, and has a thumb and index crank like a nose on the
middle of its face. It is much more selective in what it gives
credit for. @ut #14 washers and, if you use great care, round
Pop tops if they are both scotch taped can achieve the desired

A RED BOX IN EVERY POT
If you are one of those readers who would love to build a
red box but don't have electronic experience, the tape
method is for you. With only a small cassette recorder
(price-$25) and a telephone Pickup coil(about $2) you can
easily and quickly record the sound of pay phone money.
The pay phones are now Single-slot types which make a
tone when you deposit coins, but the earpiece is discon-
nected momentarily so that you hear nothing. But if you
call up a friend and deposit money, he will hear it, He
can then record the tones off of his Phone, and use them
whenever he goes to a pay phone to make long-distance
calls.
‘The usual method is to have your friend call you at the
Pay phone(one that rings; some don't) and this way you can
deposit money and get it back when you hang up, Pickup &
hang up again. You deposit 6 quarters, 2 dimes, and 2
nickels. The tape can be played to the operator for a sum
of $1.80, or rewound quickly for more quarters or dimes
or whatever,
Volume is important if the operator is to be fooled. The
beeps should be loud and clear, with little background noise.
A recorder with Automatic Level (AGC) is good to use for
recording. For playback to the operator, a small 2 1/2"
external speaker is useful, because you can easily take it
away from the mouthpiece of the phone when you want to
skip a particular coin sound. The correct volume is set
as follows: At the pay phone, alternately play the tape and
deposit money, holding the speaker about 1" from the phone
mouthpiece, When your friend hears the two at the same
tevel, mark the volume ‘control on the cassete for future use.
It!s that easy] Use phone booths where people won't see you
playing the recorder and become suspicious. And in case
your suspicions are aroused, simply erase the tape.
DEAR YIPL
I have some black-box info you might be interested in.
This info came from a Bell V. P, talking to his nephew.
He says some central Offi¢es have a computer tied in to
all its tandems which randomly checks the resistance of
the calls going on. When it detects a low-resistance call it
prints out all available info, your number, his number, time
SuppoSedly the second time the same conditions are detected
between the same two numbers someone gets screwed, usu-
ally he who has the box. I can't Say how true all this is,
but its plausible, they do have diagnostics equipment.
In R.L,(A.C, 401) 959-XXXX (any numbers) gives a high
Pitch that makes the tandem cheep, 958-XXXX gets some
lineman's office. 955-XXXX gives employee new and Bell
vropoganda.238-0000
gives you a line that doesn't ring or
answer, All should be free. It would be a great user ser-
vice if you could compile and publish a list of what over-
Seas senders go where,
P. S, - I would appreciate it if you could clarify your
mail status and how the F, Bl. gets your subscriber's
names,
-SAVROK, R.L -
We bulk mail at the post office where they are broken up
into different mail bags. From that point the issues are
Scattered around the country, and our mail gets probably
more mishandling than outright censoring, due to sloppily
managed postal service. It is also Possible that certain
individual postmen throw out YIPLs, but if a manager did
it as policy it would leak out too fast. Cooperation between
the post office and FBI in revealing subscriber names is
totally illegal and would be very embarassing if leaked. Not
to mention that we will sue all Parties involved if it occurs,
All you postal workers let us know what treatment YIPL
mail gets in your area, We might mention that we do not
trade, sell, or otherwise expose our mailing list.

DEAR YIPL
‘Those individuals who are in the habit of squirting
epoxy into pay phone coin slots would be better advised
to squirt it into the locks instead. That way the machines
will function in case someone needs it. Of course, up-
right, moral YIPL readers love Pa Bell too much to do
such a thing.

DEAR YIPL
Only problem with red box #16: faint tone(constant) in
background with periodic soft beeps even when no button
is depressed. Can anything be done?
I bought what I thought were good quality ($1.20) Inter-
national rectifier switches (coin silver contacts, etc.) and
they're hogwash. Will look for better constructed versions.
Thanks for all-you folks are beautiful,
-MM, NY-
You've got a leakage problem. Some possibilities are to
decrease the 47K resistor on the base of the shorting
transistor, decrease the 22K resistor of the same trans-
istor, or increase the 5 mfd. capacitor in the emitter
circuit, Or try this: Move the collector of the shorting
transistor to the other side of the .01 mfd. capacitor. This
will almost surely load the oscillator beyond hope when the
shorting transistor is turned on, but may affect the charac-
ter of the beeps. It shouldn't
be too serious, however.

CAUTION: THIS IS NOT A FOOLPROOF FONE TAP DETEC-
TOR, but it's great for finding out if all the extensions in your
home are hung-up. So if you're going to talk about "Konfiden-
tial Matters" or other "Dopee Subjects" you're sure that when
you say "I've got it maw" no one else has it too.
To insure that all phones on your end of a conversation are
hung-up, construct the very simple line voltage detector shown
here, The light
bulb is a 5 volt miniature type, such
as a 1490
or ano, 27. Ideal is the phone company's own tiny slide-base
jJamps found in multi-button (hold-button) Phones. For these ,
use a 470 ohm, 1/2 watt resistor to lengthen the life. ‘The
capacitor is a 50 midi, , 100 volts or greater electrolytic type.
Get the parts out of any radio or electrical store for about $2.
‘Then connect each of the two contacts from the light to the two
contact wires of the capacitor, and install both
the
blue wire(inside the phone) and the "F" Screw, where the blue
wire normally connects to. Be careful not to touch other screws
or wires with the new parts you install. Carefully wrap up the
connections with tape and close up the phone. Test thé light by
Picking up the phone. The light will light, and if someone picks
up an extension, it will go very dim or completely out.
HOW IT WORKS: When a fone is in use(without a black box)
the voltage on your phone line drops to about 4 volts, If the
lamp is wired as shown, the 4 volts will flow through it when
the phone is picked up. If another phone is used, the line drops
to only 2 volts, and the light gets weaker. This other phone,
however, must be on your phone line, and not, for example, on
the line of
a friend you're talking to, The capaciwr allows the
high ringing voltage to pass around the lamp, so that the bulb is
not accidentally fizzed if the pnone 1s picked up during a ring,
You can install this in any normal dial phone, even if already
equipped with a black box (Issue 11), The light will not light
during free long-distance calls, however since we don't make
free long-distance calls that's a minor problem, no?

It's not just the rate increases that burn me up about Bell.
It's those local calls that sound like there's an atomic war
on, after you've dialed a wrong number three times in a row.
It's that lousy Bell service.
Lousy service comes from rotten equiptment and asinine
employees. The equiptment is rotten because Bell doesn't
feel like buying new equiptment. It costs money and doesn't
make money for them. Thus, there is no reason. People
don't enjoy peircing tones that blow their ears out, or taps
and clicks constantly on their private conversations. But
people don't count, unless they're the few who own stock,
lots of stock, It's a fact that in New York City the phone com-
pany puts the new equiptment in the richer areas and badly
neglect service in predominantly non-white areas. Recently
they sent out printed leaflets in the bills saying that they
were changing to a new dial tone to improve service. Result-
a new dial tone with no improvement in service.
The employees are another problem. Though there are
many polite employees, the bad ones do their best to make
up for their numbers. They listen to your conversations,
act like they do you a favor, and cut you off if you start to
get apoplectic from not being able to strangle them, It has
often happened that an operator will accuse you of being a
bother or of lying to them, and they then pronounce your
sentence- your phone will be disconnected for the night. Too
bad you only get credit if service is cut for 24 straight hours.
And if you call the business office you get to talk to the latest
invention of Bell Laboratories-computor people. They recite
certain phrases and no others. Sometimes they blow a fuse
and keep repeating phrases in random incoherent tones.
You don't have to be sick to work for Bell; as their ads
say, "We'll train you". Why do some operators monitor
your calls? Because operators themselves are harassed
and monitored by their supervisors, and the supervisors
don't make clicks when they listen to you_and the operator.
Employees are treated like children, like boy scouts, or
as if they're in the army (2s many employees are hired
because they're "pre-disciplined"), Employees are urged
to act like they have some personal stake in AT&T and to
protect its equiptment with their life. Little insects that
eat cloth wire remain a pain in the ass to operators bodies
because Pa Bell won't spray their fossilized equiptment or
(God forbid!) replace it with plastic wires. Profits before
People-AT&T's Success Story!
But cheer up folks!
Soon AT&T will eliminate thousands
of jobs by charging
for information calls, brainwashing us
into dialing our own calls, and soon there will just be one
big daddy computor®AND THAT'S ALL! Who needs people
