Digital Encryption modules for Tait radios. Model NDB-750t

Wire-in Encryption modules
Our easy-to-fit 256-bit AES Digital Encryption plug-in modules easily convert Tait analogue radios into secure digital radios and therefore:

  • Works seamlessly.

  • Guards against eavesdropping or unauthorised listening.

  • 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 Tait 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, Icom, Kenwood, Vertex Standard 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 Tait radios which can install our plug-in modules:
- Orca 5000 Series Portables,T2000 and T8000 Mobiles radios, equipped with special flex (supplied by Tait).

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.

Special Starter Pack offer for £349.00!
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 (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.
