HF/VHF
TACTICAL COMBAT NET RADIO

CNR 2000

The CNR-2000 Family is a new
line of Marconi Selenia
Communications HF/VHF (1.6
MHz to 60 MHz) multiband ,
multirole, multifunction tactical
radio communication transceivers
embedding within a single package
the capabilities for different
operational roles in the
battlefield.

Operation over the extended 1.6
MHz to 60 MHz frequency range
allows short/medium/long haul
communications over LOS (Line Of
Sight), ELOS (Extended Line Of
Sight) and BLOS (Beyond Line Of
Sight) links with HF and VHF tactical
radios.

The open system, software
programmable architecture of the
CNR-2000 family allows the
expansion/customisation of
capabilities to meet specific
requirements and a progressive evo­lution towards future configurations
of the 21st Century tactical radio, in
line with the requirement for full
integration of lower-echelon field
units into the Command and
Control System.

The CNR-2000 equipment have
embedded facilities for operation as
elements within radio networks and
as radio communication
components interfacing with wired
communication systems, providing:

- Situational awareness using GPS
positioning data

- CNRA (Combat Net Radio
Access) services, such as
addressed call facilities between
CNR-2000 users and connection
to external tactical and
infrastructure networks.

EPM protection can be provided by
a TRANSEC/COMSEC proprietary
scheme implemented as an EPM
internal SW module.

STANAG-4444 will be implemented
as a future enhancement of the HF
EPM capability.

The CNR-2000 Family includes the
following equipment:

- SRT-178/M 25W HF/SSB -
VHF/FM 10W for manpack use

- SRT-178/VM 25W HF/SSB - VHF/FM
10 W for vehicular installations

- SRT-278/VM 125W HF/SSB -

VHF/FM 50 W for fixed/semifixed
installations with external High
Power Amplifier and Antenna
Tuning Unit

The primary role of the SRT-178/M
is to operate as a Combat Net
Radio in voice/data wireless
networks in the Forward Area,
providing connection between group
members at different levels.

These capabilities mean
unconstrained mobility, operational
flexibility and quick deployment in
the tactical battlefield.

The SRT- 178/VM and SRT-278/VM
are primarily intended for
deployment in vehicular, sheltered
or fixed Command Posts.

All the above three configurations,
are built around a common
Receiver/Exciter Unit which is
associated with:

- a built in RF Power Amplifier
suitable for rated RF power level

- a built in Automatic Antenna
Tuning Unit capable of matching
a wide selection of tactical whip
and wire antennas and mounting
