] Bug detection on home phones [
|
|
<=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=>
|
|
|
|
First of all to test for bugs,you need a VOM(Multi-meter),the higher
|
|
the impedance the better.
|
|
|
|
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(Ma Bell
|
|
does not like you to cut her off completely).The scheme is 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 ee set your resistance of
|
|
the phone line,it should be very high on the order of millions ohms or
|
|
more,this is the normal condition, since you are measuring 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 parralell 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 or two
|
|
ohms at the most in a big house w/alot 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 to-
|
|
gether and you notice the resistance reads about 1-2K ohms,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 & off-hook is about 6-10 volts. Any
|
|
other conditions may mean telephone survelliance.
|
|
|
|
If you use a Wide Range Audio freq. generator and call your house,apart-
|
|
ment,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,girl-friend(boy-friend),or a business associate maybe monitor-
|
|
ing your phone activities.
|
|
|
|
An infinity transmitter is a neat device. It allows you to call the
|
|
bugged place and shuts off the ringer and defeats the switch-hook,so that
|
|
a mouth piece becomes a room bug.It was originally sold to the traveling
|
|
business man to make sure his wife was safe at home & not being attacked
|
|
(or f^ckin her boyfriend behind his back)
