HERE IS SOME INFO ON PHONE TAPS. I HAVE ENCLOSED A SCHEMATIC FOR A SIMPLE
|
|||
|
|
WIRETAP & INSTRUCTIONS FOR HOOKING UP A TAPE RECORDER CONTROL RELAY TO THE
|
|||
|
|
PHONE LINE.
|
|||
|
|
|
|||
|
|
FIRST I'LL DISCUSS TAPS A LITTLE. THERE ARE MANY DIFFERENT TYPES OF TAPS.
|
|||
|
|
THERE ARE TRANMITTERS, WIRED TAPS AND INDUCTION TAPS TO NAME A FEW. WIRED AND
|
|||
|
|
WIRELESS TRANSMITTERS MUST BE PHYSICALLY CONNECTED TO THE LINE BEFORE THEY'LL
|
|||
|
|
DO ANY GOOD. ONCE A WIRELESS TAP IS CONNECTED TO THE LINE, IT CAN TRANSMIT ALL
|
|||
|
|
CONVERSATIONS OVER A LIMITED RANGE. THE PHONES IN THE HOUSE CAN EVEN BE
|
|||
|
|
MODIFIED TO PICK UP CONVERSATIONS IN THE ROOM & TRANSMIT THEM TOO! THESE TAPS
|
|||
|
|
ARE USUALLY POWERED OFF THE PHONE LINE, BUT CAN HAVE AN EXTERNAL POWER SOURCE.
|
|||
|
|
|
|||
|
|
WIRED TAPS, ON THE OTHER HAND, NEED NO POWER SOURCE, BUT A WIRE MUST BE RUN
|
|||
|
|
FROM THE LINE TO THE LISTENER OR TO A TRANSMITTER. THERE ARE OBVIOUS
|
|||
|
|
ADVANTAGES OF WIRELESS TAPS OVER WIRED ONES. THERE IS ONE TYPE OF WIRELESS
|
|||
|
|
TAP THAT LOOKS LIKE A NORMAL TELEPHONE MIKE. ALL YOU HAVE TO DO IS REPLACE THE
|
|||
|
|
ORIGINAL MIKE WITH THIS & IT'LL TRANSMIT ALL CONVERSATIONS!
|
|||
|
|
|
|||
|
|
THERE IS AN EXOTIC TYPE OF WIRED TAP KNOWN AS THE 'INFINITY TRANSMITTER' OR
|
|||
|
|
'HARMONICA BUG'. IN ORDER TO HOOK UP ONE OF THESE, YOU NEED ACCESS TO THE
|
|||
|
|
TARGET TELEPHONE. IT HAS A TONE DECODER & SWITCH INSIDE. WHEN IT IS
|
|||
|
|
INSTALLED, SOMEONE CALLS THE TAPPED PHONE & *BEFORE* IT RINGS, BLOWS A WHISTLE
|
|||
|
|
OVER THE LINE. THE X-MITTER RECEIVES THE TONE & PICKS UP THE PHONE VIA A
|
|||
|
|
RELAY. THE MIKE ON THE PHONE IS ACTIVATED SO THE CALLER CAN HEAR ALL
|
|||
|
|
CONVERSATIONS IN THE ROOM.
|
|||
|
|
|
|||
|
|
THERE IS A SWEEP TONE TEST AT 415/BUG-1111 WHICH CAN BE USED TO DETECT ON OF
|
|||
|
|
THESE TAPS. IF ONE OG THESE IS ON YOUR LINE & THE TEST # SENDS THE CORRECT
|
|||
|
|
TONE, YOU'LL HEAR A CLICK.
|
|||
|
|
|
|||
|
|
INDUCTION TAPS HAVE ONE BIG ADVANTAGE OVER TAPS THAT MUST BE PHYSICALLY
|
|||
|
|
WIRED TO THE PHONE. THEY DON'T HAVE TO BE TOUCHING THE PHONE IN ORDER TO PICK
|
|||
|
|
UP THE CONVERSATION. THEY WORK ON THE SAME PRINCIPLE AS THE LITTLE SUCTION-CUP
|
|||
|
|
TAPE RECORDER MIKES YOU CAN GET AT RADIO SHACK. INDUCTION MIKES CAN BE HOOKED
|
|||
|
|
UP TO A TRANSMITTER OR BE WIRED. HERE IS AN EXAMPLE OF INDUSTRIAL ESPIONAGE
|
|||
|
|
USING THE PHONE: A SALESMAN WALKS INTO AN OFFICE & MAKES A FONE CALL. HE
|
|||
|
|
FAKES THE CONVERSATION, BUT WHEN HE HANGS UP HE SLIPS SOME FOAM-RUBBER CUBES
|
|||
|
|
UNDER THE HANDSET, SO THE FONE IS STILL OFF THE HOOK. THE CALLED PARTY CAN
|
|||
|
|
STILL HEAR ALL CONVERSATIONS IN THE ROOM. WHEN SOMEONE PICKS UP THE FONE, THE
|
|||
|
|
CUBES FALL AWAY UNNOTICED. I USE A TAP ON MY LINE TO MONITOR WHAT AE-PRO IS
|
|||
|
|
DOING WHEN IT AUTO-DIALS, SINCE IT DOESN'T TAKE ADVANTAGE OF THE HANDSET ON THE
|
|||
|
|
APPLE CAT II. I CAN ALSO HOOK UP THE TAP TO A CASSETTE RECORDER OR AMPLIFIER.
|
|||
|
|
|
|||
|
|
HERE IS THE SCHEMATIC:

|

|
|
!<INPUT
|
|||
|
|
|
|||
|
|
THE 100K POT IS USED FOR VOLUME. IT SHOULD BE ON ITS HIGHEST (LEAST RESISTANCE)
|
|||
|
|
SETTING IF YOU HOOK A SPEAKER ACROSS THE OUTPUT, BUT IT SHOULD BE SET ON ITS
|
|||
|
|
HIGHEST RESISTANCE FOR A TAPE RECORDER OR AMPLIFIER. YOU MAY FIND IT NECESSARY
|
|||
|
|
TO ADD ANOTHER 10-40K. THE CAPACITOR SHOULD BE AROUND .47 MFD. IT'S ONLY
|
|||
|
|
PURPOSE IS TO PREVENT THE RELAY IN THE CO FROM TRIPPING & THINKING YOU HAVE THE
|
|||
|
|
FONE OFF THE HOOK. THE AUDIO OUTPUT TRANSFORMER AVAILABLE AT RADIO SHACK
|
|||
|
|
(273-1380) IS FINE FOR THE X-FORMER. THE BLACK & GREEN ARE FINE FOR INPUT & THE
|
|||
|
|
RED & WHITE GO TO THE OUTPUT DEVICE. YOU MAY WANT TO EXPERIMENT WITH THE
|
|||
|
|
X-FORMER FOR THE BEST OUTPUT. HOOKING UP A TAPE RECORDER CONTROL RELAY IS EAST.
|
|||
|
|
JUST ONE OF THE FONE WIRES (USU. RED) BEFORE THE TELEPHONES & HOOK ONE END TO
|
|||
|
|
ONE WIRE OF THE RELAY & THE OTHER END TO THE OTHER RELAY WIRE. LIKE THIS:
