The New Nabishi HF
Digital Radio Encryption System can be
connected internally
(with a wire-in module) or externally (with an
Interface box unit)
Nabishi's Digital Encryption system for HF
Radios, including
SB
&
SSB
(side band and single side band) mode, utilises the
NHF-256B (External Interface) and NHF-256M
(Wire-in Module) with a 256-bit AES
algorithm convert normal voice
communications into encrypted
DIGITAL voice communications
make your calls totally secure against all
levels of
eavesdropping . With our new NHF-256b
External interface system, it is even easier
to convert existing HF analogue (analog) transceivers
to Secure Encrypted Digital voice with NO
transceiver modifications.
The NHF-256b External interface system and
the NHF-256m wire-in module will
automatically detect a digital signal and
decodes it and channel the audio in clear or
secure mode, so you also maintain full
analogue capabilities. Our
Digital Encrypted
Voice
Encryption could be the biggest
revolution in HF radio since SSB!
Our HF encryption modules have been tested
and work with Vertex, Icom, Barratt, Codan
and many other makes of HF radios.
Digital Encryption modules are also modules
for VHF & UHF radios.

Special Starter Pack offer!
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
internally or externally)
in all makes of HF radios
The package
consists of 2 internal modules or
external interface units,
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
(setup instructions are supplied). |
