   simple wiretap & instructions for hooking up a small tape recorder
   control relay to the phone line.
          
   First, I will discuss taps a little. There are many different types of
   taps. there are transmitters, wired taps, and induction taps to name a
   few. Wired and wireless transmitters must be physically connected to
   the line before they will do any good. Once a wireless tap is      
   connected to the line,it can transmit all conversations over a limited

   reception range. The phones in the house can even be modified to pick
   up conversations in the room and transmit them too! These taps are
   usually powered off of the phone line, but can have an external power
   source. You can get more information on these taps by getting an issue
   of Popular Communications and reading through the ads. 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 and it will transmit all conversations!
   There is also an exotic type of wired tap known as the 'Infinity
   Transmitter' or 'Harmonica Bug'. In order to hook one of these, it
   must be installed inside the phone. When someone calls the tapped
   phone & *before* it rings,blows a whistle over the line, the      
   transmitter picks up the phone via a relay. The mike on the phone is
   activated so that the caller can hear all of the conversations in the
   room. There is a sweep tone test at 415/BUG-1111 which can be used to
   detect one of these taps. If one of these is on your line & the test #
   sends the correct tone, you will hear a click. Induction taps have one
   big advantage over taps that must be physically wired to the phone. 
   They do not have to be touching the phone in order to pick up the[62Dversation. They work on the same principle as the little           
[75C[3
   suction-cup tape recorder mikes that you can get at Radio Shack.     
   Induction mikes can be hooked up to a transmitter or be wired.    
   [KHere is an example of industrial espionage using the phone:           
   [KA salesman walks into an office & makes a phone call. He fakes the   
   conversation, but when he hangs up he slips some foam rubber cubes    
   into the cradle. The called party can still hear all conversations in[67De room. When someone picks up the phone, the cubes fall away        
   unnoticed.[K
   [KA tap can also be used on a phone to overhear what your modem is doing
   when you are wardialing, hacking, or just plain calling a bbs (like

   Amiga! Ibm! CALL IT! 303-972-8566! By the way, i did this ad without

   [K[KThe 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  [64Delay in the phone from tripping & thinking that you have the
   phone off of the hook. the audio output transformer is available at
   Radio Shack. (part # 273-138E for input). The red & the white wires go
   to the output device. You may want to experiment with the transformer 
   for the best output. Hooking up a tape recorder relay is easy. Just
   hook one of the phone wires (usually red) to the the end of one of the
   relay & the there end just loop around. This bypasses it. It should 
   look like this:[K

   (part #275-004 from Radio Shack works fine)[K
   [K[K[KIf you think that you line is tapped, the first thing to do is to  
   physically inspect the line yourself ESPECIALLY the phones. You can
   get mike replacements with bug detectors built in. However, I would
   not trust them too much. It is too easy to get a wrong reading.
