D856-BM BlackMic

Real Digital Voice Remote Speaker Microphone  

 

Filcom’s real-life digital encryption unit the D856-BM BlackMic includes all elements of typical digital encryption system: a digital speech coder (vocoder) which transforms the speech into a digital bit stream, a digital encryption & decryption block to encode and decode the bit stream, and a modem to transmit and receive the encrypted digital information

The D856-BM BlackMic applies a complex adaptive mechanism, so it is especially perfect on HF channels where signal propagation is determined by the fact that it's repeatedly reflected from the ionosphere and the earth surface and significant changes of propagation conditions depending on the geographical location, frequency, time of day, season, solar activity, and other circumstances.

The user of the D856-BM BlackMic can work with one from 3 (three! – 600, 1200 or 2400 bps) rates of built-in vocoder depending on the current propagating conditions.

The D856-BM BlackMic automatically detects and processes the incoming signal with different bps rates (Autobaud).

The D856-BM BlackMic automatically detects and processes the incoming signal clear or encrypted (Automode).

The D856-BM BlackMic is connected to most modern commercial radios and transceivers;

The D856-BM BlackMic has the ability to be upgraded with any future improvements via upgrade file.

The programming and key loading is occurred via PC.
