APJ1 SigDef-2D HF/SSB External Technical

The SigDef-2D HF/SSB External Encryption Unit is a low voice rate and high data rate HF modem for secure communications. The SigDef-2D can be connected to most modern HF transceivers and VHF/UHF radios. Secure Voice and Data communications are critical to protecting private information and confidential conversations from casual eavesdroppers, the public, business competitors, criminals, terrorists and enemies. Add-on Voice and Data security units used to keep confidential information away from unwanted listeners to protect businesses, property and personnel

 

A voice part of the SigDef-2D includes all elements of typical digital voice encryption system: a digital speech coder (vocoder) which transforms the speech into a digital bit stream, a digital encryption and decryption block to encode and decode the bit stream, and a modem to transmit and receive the encrypted digital information.

The user of the SigDef-2D can work with one of 3 (three! – 600, 1200 or 2400 bps) Digital Voice rates of built-in vocoder selected by user in depending on the current propagating conditions. The SigDef-2D will automatically detect and processes the incoming Digital Voice with different rates (Autobauding). The SigDef-2D will automatically detect and processes the incoming clear or encrypted Digital Voice (Automode). A data part of the SigDef-2D is a 9 rate HF modem. The maximum data rate is 9600 bps (coded) and 12800 bps (uncoded). An additional speaker up to 12 W can be connected to the SigDef-2D.

The SigDef-2D has the ability to be upgraded with any future improvements via upgrade file. An internal Encryption Board is intended for implementation of Customer Encryption Feature and other secure requirements The programming and key loading is occurred via PC.

The SigDef-2D is supplied with a standard APJ1-SM10, K-Type speaker-Microphone

Options
* SigDef1-P001USB Programming Cable
* SigDef1-Axxx to radio interface lead
