|
<p>Why does the FBI and other select government agencies pay over $4000 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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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
|
|
<special>N</special>Law and Order and could not.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>Full Disclosure's investigative reporting team, was able to obtain complete
|
|
specifications on both the recorder and playback unit.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>The following public disclosure of the JBR specifications should serve two
|
|
purposes:</p>
|
|
|
|
<p>1) to open a competitive market for this type of recorder, and</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>@SUBHEAD = JBR RECORDER</p>
|
|
|
|
<p>"The recorder is stereophonic, with two totally independent channels. A
|
|
third central track records a reference signal of 5461 Hz. This signal is
|
|
used later on in the playback system as a reference, in order to correct for
|
|
speed variations.</p>
|
|
|
|
<p>"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.</p>
|
|
|
|
<p>"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.</p>
|
|
|
|
<p>"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.</p>
|
|
|
|
<p>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.</p>
