     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 to cut her off
completely).  The scheme is to physically isolate your house,
apartment, etc. from the outside world.  But before you do this,
measure the line voltage (should be about 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 a million ohms or
more, this is  the  normal  condition, since you are measuring the
resistance of an open circuit.  If it is much less, such as 50-100K
ohms then you have 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
pro1{ably have a line tap.

     Now, if you also make a measurement with the wire end twisted
together and you  notice  the resistance reads around 1-2Kohms, then
you may have a drop-out relay.  A drop-out relay is a relay that
sense 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 is to  measure your line voltage.  On hook voltage is about
48V, off hook about 6-10, and ringing is up there at 96V.  Any other
conditions may mean telephone surveillance.

     If you use a Wide Range Audio frequency generator and cal1 your
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 in 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 well tell you that your wife/husband, girlfriend (or boyfriend-
or business associate may be monitoring your phone activities.

     An infinity transmitter is a neat device that allows you to call
the bugged place and shut off the ringer along with defeating the
switchhook when a preset tone is played, so the mouthpiece then
becomes a room bug.  They were originally sold for the travelling
businessman to make sure his wife was safe at home (or fucking her
boyfriend behind his back)
