Bug Detection on Home phones
|
|||
|
|
(COURTESY OF DR JIMMY AND MR JIM)
|
|||
|
|
|
|||
|
|
|
|||
|
|
First of all to test for bugs, you need a VOM (Multimeter) the higher the
|
|||
|
|
impedance the better (a Digital with FET circuitry or a Vacuum Tube Volt Meter
|
|||
|
|
is the best).
|
|||
|
|
|
|||
|
|
First disconnect the phone line(s) AT BOTH ENDS. Undo the phone instrument
|
|||
|
|
and hook it up to the entry point of the phone line from the outside world (Ma
|
|||
|
|
Bell does not like you cut her off completely.) The scheme is the physically
|
|||
|
|
isolate your house, apartment, etc from the outside world. But before you do
|
|||
|
|
this measure the line voltage (It should be approximately 48 Volts).
|
|||
|
|
|
|||
|
|
Now with the wires disconnected at both ends set your resistance scale to a
|
|||
|
|
high reading and measure the resistance of the phone line, it should be very
|
|||
|
|
high on the order of million ohms or more, this is the normal condition, since
|
|||
|
|
you are measuring the resistance of an open circuit. If it is much less, say
|
|||
|
|
50-100Kohms then you a device on the line that does not belong there, probably a
|
|||
|
|
parallel bug.
|
|||
|
|
|
|||
|
|
Now twist the end of the disconnected wire and go to the other end and measure
|
|||
|
|
the resistance of this. This resistance should be about one ohm or two at the
|
|||
|
|
most in a big house with a lot of phones. If it is more, then you probably have
|
|||
|
|
a series bug.
|
|||
|
|
|
|||
|
|
If in the first case, taking parallel measurements using a meter (not LED/
|
|||
|
|
LCD) and you notice a "kick" in the needle, you probably have a line tap.
|
|||
|
|
|
|||
|
|
Now if you also make a measurement with the wire end twisted together and you
|
|||
|
|
notice the resistance reads about 1-2kohms, then you may have a drop-out relay.
|
|||
|
|
A drop-out relay is a relay that senses a phone going off hook, and signals a
|
|||
|
|
tape recorder to start recording.
|
|||
|
|
|
|||
|
|
Another test to do with the phones still hooked up to the outside world, on
|
|||
|
|
hook voltage is about 48 Volts and off hook is about 6-10 Volts. Any other con-
|
|||
|
|
ditions may mean telephone surveillance.
|
|||
|
|
|
|||
|
|
If you use a Wide Range Audio frequency generator and call you house,
|
|||
|
|
apartment, etc. from another phone and sweep up and down the spectrum, and you
|
|||
|
|
notice the phone answers itself somewhere in the sweep you probably have an
|
|||
|
|
infinity transmitter on your line.
|
|||
|
|
|
|||
|
|
The above information tells nothing about TELCO taps at the central office, or
|
|||
|
|
anywhere else along the line, but this information may tell you that your wife,
|
|||
|
|
girlfriend (boyfriend), or business associate may be monitoring your phone
|
|||
|
|
activities.
|
|||
|
|
|
|||
|
|
An Infinity transmitter, is a neat device It allows you to call the bugged
|
|||
|
|
place and it shuts off the ringer and defeats the switchhook, so the mouthpiece
|
|||
|
|
now becomes a room bug. It was orginally sold from the travelling business man
|
|||
|
|
to make sure his wife was safe at home not being attacked (or fucking her
|
|||
|
|
boyfriend behind his back).
