TRANSCEIVER

CLEAR VOICE
Excellent sensitivity and the high
dynamic range of the NGT™ receiver
ensures better reception in the most
difficult 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 identifies 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 specific 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 benefit 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 fitted 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 MixedExcitation 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 certified 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 significantly less
sounding activity required.
The Listen-Before-Transmit capability
detects voice and data traffic on the
channel before initiating ALE. This
prevents calling on channels that
already have traffic.
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 USERFRIENDLY 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 efficient
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 configuration and
management of equipment setup.
The NGT™ SRx can be tailored
according to the needs of different
users through features such as
configurable hot keys to provide easy
access to one-touch calling and
pre-programmed sequences.

SMART MONITORING AND SCANNING

GPS SUPPORT

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 efficient scanning time
possible for Selcall, ALE and
voice detection.

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.

The NGT™ SRx features flexible
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 specifically is
received. This relieves the operator
from continuous manual monitoring
for relevant incoming traffic.

DATA SERVICES
The NGT™ SRx supports a full
range of data capabilities through
the Codan 3012, 3212 and RM50e
modem products.
In standard configuration, 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 difficult
conditions often encountered over
HF links. Data transfers in email, file
transfer and chat format are fully
supported using Codan’s
UUPlus™ software.
When fitted with the wideband
2.7 kHz filter 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 fitting 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 configurations are fully
integrated with Selcall and ALE call
systems resulting in a seamless end
to end data solution that is efficient
and easy to operate.
