This transmitter is used both for wiretapping and room monitoring, and transmission of the obtained informations through a crystal controlled radio channel.
The micro-transmitter is a compact module, equipped with external antenna, microphone, and flexible wires to connect it to the telephone line.
Connection is done by tearing open one of the wires of a standard analog telephone line; the line is also used as a power supply.
The transmitter can automatically
switch between room and telephone monitoring modes.
While the phone handset is hung up, the transmitter remains in room
monitoring mode. As soon as the handset is picked up, the
transmitter would automatically switch to the telephone monitoring
mode.
Since its power comes from the
telephone line, its operating time can be virtually unlimited.
Furthermore, connecting the unit to the telephone line does not
cause any effect or interference.
The conversion of the analog signal into digital is performed via
the Adaptive Delta Modulation (ADM) method.
