	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 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 "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....

	-----------------------------------------------------------------

	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.
