HF TRANSCEIVER
™
Codan’s Envoy™ 2200 series HF Transceiver delivers
dependable, clear, trouble-free voice and data
communications in challenging environments,
without dependence on existing infrastructure.
With 125 W of power, Envoy™ is offered in
mobile and base station confi gurations.
SOFTWARE-DEFINED ARCHITECTURE
Envoy™ uses latest-generation high-performance Digital
Signal Processor (DSP), Field-Programmable Gate Array (FPGA)
and microprocessor technology. This provides market-leading
performance and the assurance of protection of your investment,
through future-upgradability to support evolving standards.
INTUITIVE OPERATION
With its large, high-resolution, back-lit colour display and
customisable icon-based menu system, Envoy™ is as simple to
operate as modern smartphones. Making calls is as simple as
navigating to your contact list, locating the desired contact and
pressing the “call” button.

IP remote controllable
Ethernet / USB connectivity
High-resolution colour display
Multi-lingual graphical user interface
Integrated robust 3012
compatible data modem
CES / AES encryption
Powerful PC-based
programming software
Desk console for base stations
Calling systems
4/6 digit Selcall based on CCIR 493-4
(compliant with UN open Selcall)
FED-STD-1045 ALE
MIL-ST D-188-141B ALE
MULTI-LINGUAL
To ease the training burden for non-English background users, the
Envoy™ user interface and PC programming software are available
in languages other than English.
EASY TO DEPLOY
Codan’s TPS-3250 Programming Software provides a powerful
user-friendly tool for the rapid confi guration of your Envoy™
Transceiver, and enables installation of profi les via direct USB
connection or USB memory device. Ease of fi eld deployment is
assured through the USB Smartloader capability. Alternatively
Envoy™ can be confi gured directly through the intuitive menu
system, with the assistance of the in-built quick-start guides. Access
to settings can be selectively protected via an administrator pin.
BITE
Envoy™ features Built-in Test Equipment (BITE). An automatic self-test
is run on start-up, and additional tests can be run manually. A simple
status LED indicates normal operation (green) or fault conditions
(red). Remote management is also supported via over-the-air
diagnostic and status calls.
Envoy™ continually monitors forward and refl ected power. Voltage
Standing Wave Ratio (VSWR) can be displayed to the user, and poor
VSWR (e.g. caused by an untuned antenna) is quickly reported.

HF TRANSCEIVER
SMART MONITORING AND SCANNING
When an operator is absent,
Envoy™ generates an automatic log
containing the caller’s identity, time
and channel number that can be
displayed upon their return.
With multiple net adaptive scanning,
Envoy™ 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.
Envoy™ features fl exible scanning
networks, with up to 20 scan tables
containing up to 1000 channels. Scan
rates of up to 8 channels per second
are possible, which provides increased
capacity for HF networks based
on Envoy™.
With the syllabic Voice Mute,
Envoy™ 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.
HIGH PERFORMANCE,
INTEROPERABLE CALLING
CAPABILITY
Envoy™ supports currently used
calling standards including CCIR
based Selcall, FED-STD-1045
Automatic Link Establishment (ALE)
and MIL-STD-188-141B ALE. This
ensures full interoperability with
earlier generation Codan, competitor
and legacy transceivers.
Envoy’s™ CALM™ (Codan Automated
Link Management) takes conventional
ALE to the next level through
dynamic channel characterisation,
maximising the probability of clear
communications. In addition,
Envoy™ delivers advanced
capabilities, such as call voting
and data optimised calling.
INDUSTRY-LEADING RF
PERFORMANCE
Clear voice communications and
reliable data communications are
the prime objectives of Envoy™. This
is achieved by industry-leading RF
performance specifi cations, together
with Codan’s renowned Easitalk™
noise-reduction technology.
INTERNAL EMAIL CAPABLE
DATA MODEM
Envoy™ is available with a robust
internal data modem, providing
chat and email capability. Unlike
competitor offerings, this does
not require the installation of an
additional hardware module.
VOICE SECURITY
Envoy™ 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.
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
Envoy™ are fully integrated with core
Transceiver functions like Selcall and
ALE scanning to ensure simplicity
of operation.
IP REMOTE CONTROL, CONNECTIVITY
Envoy™ features USB and Ethernet
connectivity. End-user benefi ts
include the capability for remote
control over IP, and the convenience
of deployment of confi guration
profi les through USB memory sticks.
Programming and fi rmware upgrade
are supported at high speed.
GPS SUPPORT
Envoy™ 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.
