the host radio's audio is
dramatically enhanced and becomes
much clearer due to the digitising
process.
There is a
dramatic reduction of interference from
other radio traffic as during the digitising
process interference is almost totally
eliminated.
Our Digital Encryption modules easily
convert Icom analogue (analog) radios
into digital radios with secure
256-bit AES Digital Encryption for highly secure Encryption and
protect your calls from
eavesdropping or
unauthorised listeners!
The Nabishi NDB-750 Modules
are designed for simple plug-In installation
into most makes of radios including
Motorola,
Vertex/Standard,
Kenwood,
Tait and
other makes of
radios and work seamlessly through radio
repeaters. The modules are
also available
with an optional
OTAR Management
System for:
Over-the-air
monitoring of calls
Call
logging
Interception
or locating of stolen or missing radios
Over-the-air programming of encryption
keys
These are just some of the Icom radios which
can install our plug-in modules:
IC-F34GT; IC-F44GT
IC-F3(S)/F4, IC-F3GT(GS/F4 GT(GS),
IC-F30GT(GS)/F40 GT(GS),
IC-F30(LT)/F40(LT), IC-F41GT-MT,
IC-F320(310)/F420(410),
IC-F110(111)/F210(211)
IC-F320S(310S)/F420S(410S),
IC-F110S(111S), F210S(211S),
IC-F521(F510), F621(F610)
The three outstanding
features of our
Digital Encryption modules!
We have set the
standards that
others find hard to
match.
Our modules
perform superbly
which is what sets
them apart from the
rest!
Sound
Quality - This is
outstanding in our
encryption modules and one
of the main reasons why our
Digital Encryption modules
are so successful. Without
good sound quality, most
users switch-off the
encryption and communicate
in an in-secure mode
therefore by-passing
security and allowing anyone
to listen into their over
the air conversations.
Performance &
reliability - The
performance of our Digital
Encryption modules is superb. The
modules work perfectly and reliably
even in the harshest of environments
and in all makes of radios.
Synchronisation Speed -
One of the main failures of most
encrypted radio is the
synchronisation speed which if a
radio fails to synchronise quickly,
will result in broken and un-audible
communications. In most cases, if
the communicating radios fail to
synchronise then not only there a
breakdown in communication, but also
most users will switch-off the
encryption and expose their
subsequent communications in clear
mode therefore compromising security
of their communications.
Compression
Techniques - This is the
heart of our system and one the main
reasons for the success of our
Encryption Systems. With over 18
years experience in compression
techniques, we have so perfected the
art that this creates the superb
performance which our Digital
Encryption Modules have become
famous world-wide.

Want
to see how good our encryption
modules work? here is an opportunity
for your to purchase
online a pair of our modules to
fit either
Motorola,
Icom,
Vertex/Standard or
Tait radios
or you have a pair of
wire-in modules
for other makes of radios.
The package
consists of 2 modules, programming
leads, software and installation
instructions. In most cases the
modules simply plug & play. In a few
cases a minor adjustment may be
necessary, depending on the make of
radio (simple setup instructions are
supplied).

What does it sound
like?
Eaves-droppers will only
hear "white noise" if they
listen to a
digital
encryption
transmission. When listening
to
analogue encryption they
will hear scrambled voice.
