Here is some info on phone taps. In this file is a schematic for a
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 modifies 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.
