STATE OF THE ART COMMUNICATIONS

Frequency Hopping (ECCM)
High rate frequency hopping is provided, both for point-to-point or network operation. Intelligent use of un-occupied channels and improved AGC operation ensure sustained communications in dense transmission environments.

Automatic Link Establishment (ALE) .
The embedded ALE function conforms to the interoperability requirements of MIL-STD 188-141A and includes a Quick ALE option which is up to 60% faster than MIL-STD-188-141A.

Digital squelch
The loudspeaker is only activated when an embedded intelligent squelch algorithm detects the presence of a valid signal, thus eliminating background
noise and operator fatigue, characteristic of conventional HF circuits.
- Selective Calling
  A proprietary selective calling function provides for Point-to-Point, Group and All call addressing.
Speech Enhancement
By applying speech compression and expansion
techniques the signal-to-noise ratio of voice channels is greatly improved, providing near telephone quality communications. Impulse type noise,
eg power lines and ignition systems, is very effectively suppressed by an embedded noise blanker.
- Digital Voice
  A choice of either a 2400 bps LPC 10e or 800 bps
  vocoders provides digital speech as an embedded function. The 800 bps vocoder is specifically used in the frequency-hopping mode, and ensures
  communications under poor channel conditions.
Short Message Service
The front panel is used to compose, recall, display and send short messages.
- Data Transmission
  Three embedded high rate, serial tone modems are provided:
  - MIL-STD 188110A
  - Stanag4285
  - Frequency Hopping Modem
  Forward Error Correction (FEC), interleaving and adaptive data rate techniques, combined with data stack protocols based on Stanag 5066, ensure error free data transfer between external message handling devices, requiring only low skilled operators.

Two Data Systems are available:
- One - Sisdata 2009, Standard that works with any radio permitting easy integration
- Two - Proprietor system
- Communication Security (COMSEC)
  Voice security is provided by means of either, embedded two-dimensional voice encryption, or a hardware digital encryption module. These also provide data transmission security. Crypto keys are generated and loaded from a Network Management System (NMS).
Maintenance
Various levels of Built-in Test (BIT) are provided. Power-up BIT confirms the operational readiness of the radio on switch-on, continuous BIT monitors the radio during operation. Initiated BIT reacts on operator request while Maintenance BIT stores fault occurrences.
- Configurations
  The radio is available in standard, enhanced or
  enhanced secure configuration. The radio can be used as a 25W manpack, or as a 100W vehicle/base station configuration. 400W options are also available.
  The basic radio on its own is 100 Watts and do not need one amplifier.
