Secure Digital HF Radio Encryption calls for high level voice security


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).
