The War On Privacy Hits You In The Pocket Book!
|
||
|

COPYRIGHT (C) 1991 BY FULL DISCLOSURE. ALL RIGHTS RESERVED.
|
||
|
||
Why does the FBI and other select government agencies pay over $4,000 for a
|
||
pocket tape recorder? One of the most important elements in an electronic
|
||
surveillance operation is the tape recorder. Whether hidden in one's pocket
|
||
or recording information from a wiretap or bug, the tape recorder can be the
|
||
key to success or failure.
|
||
|
||
The FBI had a need for a specialized recorder, so they contracted with the
|
||
U.S. subsidiary of a Swiss company, Nagra Magnetics, Inc. to design a
|
||
recorder that met their needs. The result being the Nagra JBR subminiature
|
||
recorder and PS-1 playback system.
|
||
|
||
When asked whether the unit was named after Jim B. Reames, an FBI employee
|
||
who helped design the recorder, a Nagra spokeswomen refused to say, but
|
||
pointed out that the initials were in fact the same.
|
||
|
||
The design and manufacture of the recorder has been so secret and important
|
||
to the FBI (and two other unnamed government agencies who are supposedly the
|
||
sole users of the recorder) that any public availability of information on
|
||
the recorder would ``make the machine extinct,'' according to an employee of
|
||
Narga who refused to provide any details on the recorder in a telephone
|
||
interview.
|
||
|
||
It is also interesting to note that in the literature obtained by Full
|
||
Disclosure from the NATIA show, several of the companies made mention of
|
||
Narga tape recorders, but not the JBR model.
|
||
|
||
A freelance reporter who contacted Nagra in August, 1990, was informed that
|
||
someone from the Justice Department had just visited to express the
|
||
government's desire to keep the public ignorant about the JBR recorder.
|
||
|
||
Full Disclosure contacted Nagra on September 24, 1990 and was informed that
|
||
they received a letter from the Government ``last week'' informing them that
|
||
they couldn't give out any information on the JBR recorder. Nagra refused to
|
||
disclose what agency sent the letter.
|
||
|
||
The company spokeswomen, also stated that they are not allowed to advertise
|
||
the unit anywhere, and if they did they would ``lose all government
|
||
contracts.'' She further stated that they wanted to advertise it in
|
||
<N>Law and Order and could not.
|
||
|
||
Marketing is done by word of mouth and narcotics trade shows, she said. This
|
||
seemed a little contrary to the first spokesman who said that there were only
|
||
three customers for the JBR recorder.
|
||
|
||
Full Disclosure's investigative reporting team, was able to obtain complete
|
||
specifications on both the recorder and playback unit.
|
||
|
||
Because of the secrecy around the recorder and its specifications, the unit
|
||
is sole-sourced from Nagra. Inevitability when a product is available from a
|
||
single source, there is no price competition.
|
||
|
||
The following public disclosure of the JBR specifications should serve two
|
||
purposes:
|
||
|
||
1) to open a competitive market for this type of recorder, and
|
||
|
||
2) to give the American public more information on the tools the government
|
||
uses to spy upon. Thereby increasing the public's ability to participate in
|
||
political process as it relates to oversight and domestic use of spy
|
||
technology.

@SUBHEAD = JBR RECORDER
|
||
|
||
``The recorder is stereophonic, with two totally independent channels. A
|
||
third central track records a reference signal of 5,461 Hz. This signal is
|
||
used later on in the playback system as a reference, in order to correct for
|
||
speed variations.
|
||
|
||
``The recording speed is 15/16 ips. This speed is stabilized by an optical
|
||
encoder system. In order to save energy and to reduce radiation as much as
|
||
possible, no erasing head is provided. For basically the same reasons, and to
|
||
ensure that the tapes remain genuine, there is also no playback facility
|
||
provided on the recorder.
|
||
|
||
``Special Kudelski cassettes are used to provide two hours non stop recording
|
||
autonomy. A set of three ``N'' size batteries are used allowing ten hours of
|
||
operation.
|
||
|
||
``Even though the detectablility is minimal, the bias frequency is of 32KHz
|
||
and has thus the same radiation as a quartz watch. The recorder weight is
|
||
less than 200 grams, includes its cassette and batteries, and is really
|
||
pocket size with cover: 110.2 x 62.6 x 20.8 mm (4.34: x 2.46" x 0.82").
|
||
Miniature microphone and remote controls are available with different length
|
||
cables.
|
||
|
||
So-called tape recorder detectors normally detect the presence of the ``bias
|
||
oscillator'' in tape recorders. By using a non-standard and one that is also
|
||
commonly used by other common devices makes detection by such a means more
|
||
difficult.
