                         PART I: THE LAW
w:
 Section 605 of tital 47 of the U.S code, forbids interception
of communication, or divulagance of intercepted communication
exept by persons outlined in section 119 of tital 18 (a portion
of the Omnibus crime controll and safe streets act of 1968).
This act states that "It shall not be unlawfull under this act
for an operator of a switchboard, or an officer, employe, or
agent of any communication common carrier who's switching system
is used in the transmision of a wire communication to intercept
or disclose intercepted communication."

hat all this legal bullshit is saying is that if you don't work
for a phone company then you cant go around tapping people's
lines. If you decide to anyway, and get caught, it could cost you
up to 5 years of your life and $10,000. This, you are all
assuming means that if you tap someone eles's line, you will be
punished....wrong! You can't tap your own line either. The
punishment for this is probably no more than a slap on the hand,
that is if they actually catch you, but it's a good thing to
know..............now on to the fun.....

                       PART II: TAPPING

verone has at sometime wanted to hear what a friend, the
principal, the prom queen, or a nighbor has to say on the phone.
There are several easy ways to tap into a phone line. None of the
methods that I present will involve actully entering the house.
You can do everything from the backyard. I will discuss four
methods of tapping a line. They go in order of increasing
difficulty.
1. The " beige box ": a beige box (or bud box) is actually better
known as a "lineman" phone. They are terribly simple to
construct, and are basically the easiest method to use. They
consist of nothing more than a phone with the modualr plug that
goes into the wall cut off, and two alligator clips attached to
the red and green wires. The way to use this box, is to venture
into the yard of the person you want to tap, and put it onto his
line. This is best done at the bell phone box that is usually
next to the gas meter. It should only have one screw holding it
shut, and is very easily opened. Once you are in, you should see
4 screws with wires attached to them. If the house has one line,
then clip the red lead to the first screw, and the green to the
second. you are then on  the "tappie's" phone. You will hear any
conversation going on. I strongly recomend that you remove the
speaker from the phone that your using so the "tappie" can't
hear evcery sound you make. If the house has two lines, then the
second line is on screws three and four. If you connect
everything right, but you dont get on the line, then you probably
have the wire's backward. Swich the red to the second screw and
the green to the first. If no conversation is going on, you may
realize that you cant tap the phone very well because you don't
want to sit there all night, and if you are on the phone, then
the poor tappie can't dial out, and that could be bad...so.......
method two.
2. The recorer: This method is probably the most widespread, and
you still don't have to be a genius to do it. There are LOTS of
ways to tape conversations. The two easiest are either to put a
"telephone induction pickup" (radio shack $1.99) on the biege box
you were using, then pluging it into the microphone jack of a
small tape recoder, and leaving it on record. Or pluging the
recorder right into the line. This can be done by taking a
walkman plug, and cutting off the earphones, then pick one of the
two earphone wires, and strip it. There should be another wire
inside the one you just stripped. Strip that one too, and attach
aligators to them. Then follow the biege box instructions to tape
the conversation. In order to save tape, you may want to use a
voice activated recorder (Radio shack $59), or if your recorder
has a "remote" jack, you can get a "telephone recorder control"
at Radio shack shack for $19 that turns the recorder on when the
phone is on, and off when the phone is off. This little box plugs
right into the wall (modularly of course), so it is best NOT to
remove the modular plug for it. Work around it if you can. If
not, then just do you best to get a good connection. When
recording, it is good to keep your recorder hidden from sight (in
the bell box if possible), but in a place easy enough to change
tapes from.

 The wireless microphone: this is the BUG. It transmitts a
signal from the phone to the radio (Fm band). You may remember Mr
microphone (from kaytel fame), these wireless mirophones are
availible from radio shack for $19. They are easy to build and
easy to hook up. There are so many differant models, that is is
almost imposible to tell you exactly what to do. The most common
thing to do, is to cut off the microphone element, and attach
these two wires to screws one and two. the line MIGHT, depending
on the brand, be "permenently off hook" this is bad, but by
phucking around with it for a while, you should get it working.
There are two drawbacks to using this method. One, is that the
poor asshole who is getting his phone tapped might hear himself
on "FM 88, the principal connnection". The second problem is the
range. The store bought transmitters have a VERY short range. I
suggest that you build the costomized version I will present in
part four (it's cheaper too). Now on to the best of all the
methods....
4. The "easy-talks": This method combines all the best aspects of
all the the other methods. It only has one drawback... You need a
set of "Easy-tylk" walkie talkies. They are voice activated, and
cost about $59. You can find em at toystores, and "hi-tech"
catalogs. I think that any voice activated walkie talkies will
work, but I have only tried the easy-talks. First, you have to
decide on one for the "tramsmitter" and one for the "reciever".
It is best to use the one with the strongest transmition to
trasmitt, even though it may recieve better also. Desolder the
speaker of the "transmitter", and the microphone of the
"reciever". now, go to the box. put the walkie talkie on "VOX"
and hook the microphone leads (as in method three) to the first
and second screws in the box. Now go home, and listen on your
walkie talkie. if nothing happens, then the phone signal wasn't
strong enough to "activate" the transmission. If this happens
there are two things you can do. One, add some ground lines to
the  microphone plugs. This is the most inconspicuous, but if it
desn't work then you need an amplifier, like a walkman with two
earphone plugs. Put the first plug on the line, and then into one
of the jacks. Then turn the voulume all the way up (w/out
pressing play). Next connect the second earphone plug to the mice
wires, and into the second earphone outlet on the walkman. now
put the whole mess in the box, and lock it up. This should do the
trick. It gives you a private radio station to listen to them on,
you can turn it off when something boring comes on, and you can
tape off the walkie talkie speaker that you have!

               PART IV: WIRELESS TRANSMITTER PLANZ

is is a tiny transmitter that consists on a one colpitts
oscillator that derives it's power from the phone line. Since the
it puts on the line is less than 100 ohms, it has no
effect on the telephone performance, and can not be detected by
the phone company, or the tappie. Since it is a low-powered
device using no antenna for radiation, it is legal to the FCC.
(That is it complies with part 15 of the FCC rules and
regulations). It, however is still illeagal to do, it's just that
what your using to do it is legal. This is explained later in
part 15... "no person shall use such a device for evesdropping
unless authorized by all parties of the conversation" (then it's
not evesdropping is it?). What this thing does,is use four diodes
to form a "bridge rectifier". It produces a varying dc voltage
varieng with the auto-signals on the line. That voltage is used
to supply the the voltage for the oscillator transistor. Which is
conected to a radio circuit. From there, you can tune it to any
zhannel you want. The rest will all be explianed in a minute....

1 may be constructed by winding approximately 40 turns of No. 36
enamal wire on a megohm, 1/2 watt resistor. The value of L1 is
not critical. L2 can be made by wrapping 5 turns of No. 20 wire
around a 1/4 inch form. After the wire is wrapped, the form can
be removed. Just solder it into place on the circuit board. It
should hold quite nicely. Also be sure to position Q1 so that the
Emmiter, Base, and collector are in the proper holes. The
schmatic should be pretty easy to follow. Although it has an
unusual number of grounds, it still works.

e odd thing about this bug that we havent encountered yet, is
that is is put on only one wire (either red or green) so go to
the box, remove the red wire that was ALREADY on screw #1 and
attack it to wire 'A' of the bug then attach wire 'B' to the
screw itself. you can adjust the frequency which it comes out on
(the Fm channel by either smooshing, or widening the coils of L2.
It takes a few minutes to get to work right, but it is also very
ersatile. You can change the frequency at will, and you can
easily record off your radio.

                  PART FIVE: HELPFULL HINTS

First of all, With method one, the beige box, you may notice that
you can also dial out on the phone you use. I don't recomend that
you do this. If you decide to anyway, and do something
conspicuous like set up a 30 person conferance for three hours,
then I suggest that you make sure the people are either out of
town or dead. In general when you tap a line, you must be
carefull. I test everything I make on my line first, then install
it late at night. I would not recoment that you leave a recorder
on all day. Put it on when you want it going, and take it off
when your done. As far as recording goes, I think that if there
is a recorder on the line it sends a sporatic beep back to the
phone co. I know that if you don't record directly off the line
(i.e off your radio) then even the most sophisticated equipment
can't ell that your recording. Also, make sure that when you
install something the people are NOT on the line. Installation
tends to make lots of scrachy sounds, clics and static. It is
generally a good thing to avoid. It doesn't take too much
intelligence to just make a call to the house before you go to
install the thing. If it's busy then wait a while. (This of
course does not apply if you are making a "midnight run").


All in all, if you use common sense, and are *VERY* Carefull,
chances are you wont get cought. Never think that your
unstopable, and don't braodcast what your doing. Keep it to
yourself, and you can have a great time.
