fully interoperable with other HF transceivers to provide

seamless HF network integration.

EASE OF USE

Codan’s NGT™ SRx is designed for quick deployment in base and

mobile confi gurations. The specially designed mounting equipment

and fl ying lead cable interfaces enable the NGT™ SRx to be installed

quickly and with minimum requirement for space while still providing

ease of access for servicing.

The handset can be mounted in any position for easy access and

viewing; especially important in a vehicle where space is limited.

With the comprehensive user-friendly interface and full control over

the handset, a driver or passenger can operate the transceiver from

any location within a vehicle.

Programmable password protected access rights can be used to tailor

the transceiver feature set and capabilities to your specifi c

user requirements, which ensures the operator is not presented with

unnecessary complexity.

Extensive Built-In-Test Equipment (BITE) capability makes it easy for

users or network administrators to analyse transceiver performance.

The 50 ohm antenna output is fully protected against any load

conditions including short circuit, open circuit and high Voltage

Standing Wave Ratio (VSWR), which can destroy other transceivers.

In the event of poor VSWR, an error is reported to the handset.

VSWR can also be reviewed via the handset at any time.

TRANSCEIVER

CLEAR VOICE

Excellent sensitivity and the high

dynamic range of the NGT™ receiver

ensures better reception in the most

diffi cult channel conditions.

The dynamic range of voice

signals is compressed prior to

transmission, resulting in clearer

and more intelligible signals for

receiving stations.

Clarity of receive signals is achieved

with Easitalk™ noise reduction,

which dynamically identifi es and

suppresses interfering non-voice

signals. Easitalk™ operates with

a single button press and results

in loud and clear voice reception

in noisy conditions. Users have a

choice of algorithms to suit personal

preferences or specifi c types

of interference.

Users looking for even greater voice

clarity can choose the MELPe based

digital voice option. The digital

voice capability provides telephone

grade voice communications and

the added benefi t of voice security.

Operators can switch between two

data rates that cater for various

channel conditions.

VOICE SECURITY

The NGT™ SRx has a choice of three

internally fi tted voice encryption

options to suit all levels of

communications security.

The CIVS voice encryption option is

a cost effective software enabled

voice scrambler capability that is

simple to use and provides a basic

level of voice security.

The CES voice encryption option

provides high level 128 bit voice

security. Up to 97 16-digit user

programmable keys are provided.

An additional layer of security is

provided through the ability to

assign a PIN number during a secure

communications session.

The AES voice encryption option

provides 256-bit security according

to the Advanced Encryption

Standard, with up to 256 user

programmable encryption keys.

Optimal voice clarity is provided

through the use of a Mixed-

Excitation Linear Predictive enhanced

(MELPe) Vocoder. The MELPe Vocoder

supports 1200 bps and 2400 bps

user selectable data rates.

All voice encryption options for the

SRx are fully integrated with core

transceiver functions like Selcall and

ALE scanning to ensure simplicity

of operation.

AUTOMATIC LINK ESTABLISHMENT

The NGT™ SRx is fully compliant

with both FED-STD-1045 and

JITC certifi ed MIL-STD-188-141B ALE

waveforms.

Codan’s implementation of ALE

incorporates unique capabilities such

as maintenance of channel quality

information (LQA) on a 24-hour basis.

This enables the transceiver to select

a suitable channel at any time of

the day, from the moment it is

switched on. This results in faster

channel selection than conventional

ALE system with signifi cantly less

sounding activity required.

The Listen-Before-Transmit capability

detects voice and data traffi c on the

channel before initiating ALE. This

prevents calling on channels that

already have traffi c.

The NGT™ SRx provides an extensive

range of ALE and Selcall based call

facilities, including Phone calls, GPS

polling and sending, Emergency calls,

and Remote Diagnostics.

The multiple network scanning

capability enables multiple networks

to be scanned simultaneously. An

ability to simultaneously decode

voice, Selcall and ALE calls on the

same channel enables maximum

interoperability in mixed vendor

network environments.

The CODAN™ NGT™ SRx

Transceiver has the ability to do

a real time channel test with

several stations then link with

the station that provides the best

communications path.

INNOVATIVE HANDSET AND USER-

FRIENDLY INTERFACE

The integrated compact design of

the handset is similar to a mobile

phone and provides easy control

of the transceiver. The handset

comprises of a microphone, a large

and wide-angle backlit LCD, and

keypad.

An adjustable backlight

automatically activates when an

incoming call is received, or when

any button is pressed. When the

transceiver is idle, an auto-dim

capability activates for effi cient

power usage.

A smart address book stores up to

100 addresses, including names, call

locations and even pre-programmed

text messages. These can be easily

retrieved via the user-friendly menu.

Access to transceiver functions

is menu-driven, which enables

easy operation for untrained

users and rapid confi guration and

management of equipment setup.

The NGT™ SRx can be tailored

according to the needs of different

users through features such as

confi gurable hot keys to provide easy

access to one-touch calling and

pre-programmed sequences.

SMART MONITORING AND SCANNING

With multiple net adaptive scanning,

the NGT™ SRx automatically adjusts

scan times for multiple networks

according to the channels’ preset

scan times. This feature gives

the most effi cient scanning time

possible for Selcall, ALE and

voice detection.

The NGT™ SRx features fl exible

scanning networks, with up to

20 scan tables containing up to 100

channels. Scan rates of up to

8 channels per second are possible

which provides increased capacity

for HF networks based on the

NGT™ SRx.

When an operator is absent, the

NGT™ SRx generates an automatic

log containing the caller’s identity,

time and channel number that can

be displayed upon their return.

With the syllabic Voice Mute, the

NGT™ SRx effectively detects

voice patterns even in high noise

environments. This ensures mute

is only opened after it detects

speech on any scanned or

monitored channels.

When Selcall or ALE selective calling

is implemented, users are able to

scan multiple channels or networks.

The operator is only alerted when a

call addressed to them specifi cally is

received. This relieves the operator

from continuous manual monitoring

for relevant incoming traffi c.

GPS SUPPORT

The NGT™ SRx supports connection

of GPS via NMEA0183 compatible

GPS receivers. This enables polling

and sending of GPS positions over air.

Distance and bearing to other users

can be displayed. When used with

Internav™ CHF tracking PC software,

up to 100 vehicles can be tracked.

Internav™ provides advanced

features such as corridor and alarm

zones, waypoints, and recording of

emergency events.

DATA SERVICES

The NGT™ SRx supports a full

range of data capabilities through

the Codan 3012, 3212 and RM50e

modem products.

In standard confi guration, the

NGT™ SRx provides error free

2400 bps and 7200 bps data

throughput using the 3012 and 3212

modems respectively. In-built data

compression makes the effective

throughput up to four times faster.

The waveforms are extremely robust

and perfectly suited to the diffi cult

conditions often encountered over

HF links. Data transfers in email, fi le

transfer and chat format are fully

supported using Codan’s

UUPlus™ software.

When fi tted with the wideband

2.7 kHz fi lter option the NGT™ SRx

can provide data rates extending

up to 9600 bps using the RM50e

modem. If even greater data rates

are required, 19200 bps can be

achieved by fi tting the NGT™ SRx

with the Independent Sideband (ISB)

option and operating the RM50e in

ISB mode. The system is supported

with the Codan STANAG 5066 based

RC50-C email client.

All data confi gurations are fully

integrated with Selcall and ALE call

systems resulting in a seamless end

to end data solution that is effi cient

and easy to operate.
