				PART I: THE LAW


Federal law:

  Section 605 of title 47 of the U.S code, forbids interception of
communication, or divulagance of intercepted communication except by persons
outlined in section 119 of title 18 (a portion of the Omnibus crime control and
safe streets act of 1968).  This act states that "It shall not be unlawful
under this act for an operator of a switchboard, or an officer, employee, or
agent of any communication common carrier who's switching system is used in the
transmission of a wire communication to intercept or disclose intercepted
communication."

  What all this legal bullshit is saying is that if you don't work for a phone
company then you can't 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 else'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

  Everyone has at some time wanted to hear what a friend, the principal, the
prom queen, or a neighbor 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
actually 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
modular 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 "tappee's" phone.  You will hear any conversation going on.
I strongly recommend that you remove the speaker from the phone that you're
using so the "tappee" can't hear every 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 don't get on the line, then you probably have the
wires backward.  Switch the red to the second screw and the green to the first.
If no conversation is going on, you may realize that you can't 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 tappee can't dial out, and that could be bad...so.......
method two.

  2.  The recorder:  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 beige box you were using, then plugging it
into the microphone jack of a small tape recorder, and leaving it on record.
Or plugging 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 alligators to them.  Then follow the
beige 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.

  3.  The wireless microphone:	this is the BUG.  It transmits a signal from
the phone to the radio (FM band).  You may remember Mr.  Microphone (from
Kaytel fame); these wireless microphones are available from Radio Shack for
$19.  They are easy to build and easy to hook up.  There are so many different
models, that is is almost impossible 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
"permanently 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 connection".  The second problem is the
range.	The store bought transmitters have a VERY short range.	I suggest that
you build the customized 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-talk"
walkie talkies.  They are voice activated, and cost about $59.	You can find
'em at toy stores, and "hi-tech" catalogs.  I think t(at any voice activated
walkie talkies will work, but I have only tried the easy-talks.  First, you
have to decide on one for the "transmitter" and one for the "receiver".  It is
best to use the one with the strongest transmission to transmit, even though it
may receive better also.  De-solder the speaker of the "transmitter", and the
microphone of the "receiver".  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 doesn'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 volume 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

  This is a tiny transmitter that consists on a one colpitts oscillator that
derives it's power from the phone line.  Since the resistance 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 tappee.  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 illegal to do, it's just that what you're using to do it is
legal.	This is explained later in part 15...  "no person shall use such a
device for eavesdropping unless authorized by all parties of the conversation"
(then it's not eavesdropping is it?).  What this thing does, is use four diodes
to form a "bridge rectifier".  It produces a varying dc voltage varying with
the auto-signals on the line.  That voltage is used to supply the the voltage
for the oscillator transistor.	Which is connected to a radio circuit.	From
there, you can tune it to any channel you want.  The rest will all be explained
in a minute....

C2,C3		     27-Pf mica capacitor
CR1,CR2,CR3,CR4      germanium diode 1n90 or equivalent
R1		     100 ohm, 1/4 watt 10% composition resistor

L2		     5 turns No.20 wire (see text)
Q1		     Npn rf transistor 2N5179 or equivalent
-----------------------------------------------------------------

  L1 may be constructed by winding approximately 40 turns of No.  36 enamel
wire on a mega-ohm, 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 emitter, base, and collector are in the proper holes.	The schematic
should be pretty easy to follow.  Although it has an unusual number of grounds,
it still works.

  The odd thing about this bug that we haven't encountered yet, is that it 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 attach 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 versatile.
You can change the frequency at will, and you can easily record off your radio.

			   PART FIVE: HELPFUL 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 recommend that you do this.  If
you decide to anyway, and do something conspicuous like set up a 30 person
conference 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
careful.  I test everything I make on my line first, then install it late at
night.	I would not recommend that you leave a recorder on all day.  Put it on
when you want it going, and take it off when you're done.  As far as recording
goes, I think that if there is a recorder on the line it sends a sporadic 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 tell that
you're recording.  Also, make sure that when you install something, the people
are NOT on the line.  Installation tends to make lots of scratchy sounds,
clicks 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* careful, chances are you
won't get caught.  Never think that you're unstoppable, and don't broadcast
what you're doing.  Keep it to yourself, and you can have a great time.
