FCC RF exposure warning
To ensure optimal transceiver performance and to avoid exposure to excessive
electromagnetic fields, the antenna system must be installed according to the
instructions provided.
High voltages exist on the antenna during transmission and tuning. Do not touch
the antenna during these activities. RF bums may result.
Install the grounding system or counterpoise as directed to prevent RF bums from
any metal part of the transceiver.
Safe working distance is based on continuous exposure to CW type transmissions,
as set out in the ICNIRP Exposure Guidelines (1998) for occupational exposure.
Safe working distance can be reduced with normal voice communication.
For FCC compliance, when the PRC-2090 transceiver is used at a power
level of 100 watts PEP, the antenna(s) used with this transceiver should be located
at least 3 metres from the operator and should not be co-located or operating in
conjunction with any other antenna or transmitter.
For FCC compliance, when the PRC-2090 transceiver is used at a power
level of 30 watts PEP, the antenna(s) used with this transceiver should be located
at least 1.5 metres from the operator and should not be co-located or operating in
conjunction with any other antenna or transmitter.

Introduction
The Barrett PRC-2090 tactical manpack is a DSP based, 500 channel HF SSB
transceiver with a frequency range of 1.6 to 30 MHz. The Barrett PRC-2090 is
designed using the latest technology enabling a physically small package with a full
feature complement.
Designed to operate in the most arduous environments encountered in tactical
manpack and tracked vehicle roles, the PRC-2090 will provide many years of
efficient and trouble free service.
The PRC-2090 supports features such as Selective Call (Selcall), direct dial
telephone connection to base stations fitted with telephone interconnect systems
(Telcall), GPS location, ALE (Automatic Link Establishment), frequency hopping,
data transmission and remote diagnostics. These features make the PRC-2090 one
of the most economical and versatile tactical HF transceivers available today.
The PRC-2090 has catered for the increased use of HF data transmission for
Internet email access and point to point data applications, by providing a
comprehensive data modem interface port, high speed transmit to receive
switching, a high stability frequency standard and an efficient cooling system
option.
The PRC-2090 can be operated either as a manpack, in a vehicle or as a fixed
station when deployed in either the vehicle docking station or base docking station.
When deployed in the vehicle or base docking station the PRC-2090 operates at
100W PEP, without the requirement for external amplifiers.
All 500 channels are available to be field or workshop programmable. Auxiliary
features such as Selcall, Telcall, scanning, mute status, alarm system etc. can be
individually enabled or disabled for every channel as required to suit your operation.
Teamed with other matching Barrett 2000 series products which include antennas,
vehicle tracking packages, HF-VHF/UHF crosspatches and HF modems, the PRC-
2090 becomes a powerful tool, providing solutions to most long distance tactical
communication requirements.

Note:- the PRC-2090 has a transmit “time-out” facility. This facility (when programmed)
allows the transmitter to be keyed in transmit mode with the PTT (transmit) switch for a
set time period, after which the transceiver switches to receive until the PTT (transmit
button is released and re-keyed. This facility prevents the transmitter transmitting for long
periods of time if, for instance, the microphone becomes jammed between seats in a
vehicle causing the PTT (transmit) switch to be held down.
Note:- Enabling, disabling and changing the time of the transmit timeout facility can
be set either when programming the transceiver or in the “General ” section of the
protected menu.

Barrett Selective Calling System
General
In addition to the use of the transceiver in simple voice mode to call other stations
there are several different types of Selective Calling systems available.
The calling systems available for the Barrett PRC-2090 transceiver are listed
below:-
International
A four and six digit Selective Call system, fully interoperable with the UN format
published in September 2004 and fully backwards compatible with all previous
Barrett 4 digit Selcall protocols.
Includes Selcall, Beacon Call, Pagecall (SMS) call, transceiver lock call and RFDS
tone calls.
Also if the options are fitted to the transceiver it includes:-
GPS calls, used to either transmit your position to another station or request
the position of another station fitted with the GPS option and receiver.
Telcalls for direct dial telephone number calling using base stations with
telephone interconnect facilities.
Person to person Secure Calls
OEM 1
A four and six digit Selective Call system compatible with other major HF
manufacturers including those using encryption. Includes Selcall, Telcall, Beacon
Call, Pagecall and GPS call.
CCIR
A four digit Selective Call system as specified by CCIR-493.
Includes Selcall, Beacon Call and tone calls.
Also, if the option is fitted to the transceiver, Telcalls for direct dial telephone
number calling using base stations with telephone interconnect facilities.
ALE FED STD 188 / MIL STD 188-141B (option)
MIL-STD Automatic Link Establishment system, see section “Automatic Link
Establishment”
30 of 285
Selective Call –“Selcall”
Selcall is a digital signalling system based on standard CCIR-493 for use on HF
networks. Each station in an HF network can be assigned up to 10 self IDs of which
there can be a mixture of four or six digit IDs (identification). The station can be
called using any of these self IDs.
Selective Call “Telcall”
Telcall uses this digital Selective Call system to transport a telephone number from
a station on an HF network to a base station equipped with a telephone
interconnect unit to initiate phone calls onto the international telephone network.
Note:- For Selcall and Telcall functions to operate the transceiver must be fitted with
the Selcall or Telcall option and the channels enabled for Selcall operation.
If Automatic Link establishment (ALE) is in use refer to the ALE section for
operation details.
Special Notes When Using OEM 1 Selective Call Protocol
All 6 digit OEM 1 protocol calls will only be decoded by other Barrett transceivers
fitted with OEM 1 Selcall protocol or other manufacturers’ transceivers using
encryption.
OEM 1 protocol 4 digit calls will be decoded by Barrett 950 transceivers, Barrett
PRC-2090 transceivers using International 4 and 6 digit Selcall and other
manufactures transceivers with similar CCIR 493 based Selective Call systems.
4 & 6 digit GPS and Status data calls use the OEM privacy key to encrypt the data.
If this 8 digit key has not been programmed by the programming software a default
privacy key of "99999999" is automatically used for transmission.
6 digit Pagecalls also use the privacy key but unlike the other calls the user has the
option to manually enable or disable the privacy key. When disabled the data is
sent as plain text. See “OEM Pagecall Key” in the protected menu “Selcall settings”
section, to switch the privacy key “On” or “Off” when sending Pagecalls.

More Selective Calling Information
Selcall Self IDs
As from software version 2.00 the 2050 transceiver can have up to 10 selcall self IDs
assigned to it. These Selcall IDs can be any combination of 4 or 6 digit OEM or
International type id.
Selcall Decode
As from software version 2.00 the 2050 transceiver has the ability to decode both OEM
and International Selcalls on any channel programmed as a Selcall channel. Calls for
each format type will only be decoded if there is at least one self id of that format
programmed into the transceiver self id group.
Selcall Transmit
Selcall formats in transmit are channel specific, only call types programmed for the
channel are permitted. This means International and CCIR format calls can only be sent
on channels that are programmed as International or CCIR selcall channels, OEM calls
can only be sent on channels that are programmed as OEM selcall channels.
32 of 285
Default Self IDs
Default self IDs are the IDs used when making a selective call. They are used when the

Checking for the Best Channel to Use Between Two Stations - Beacon Call
Before using many of the Selcall and Telcall functions in this section it is useful to
know how to use the “Beacon Call” function.
"Beacon Call" allows the operator to determine the signal quality between their
station and a station they want to call on a particular channel, but without actually
alerting the station they are doing so.
When a Beacon Call is sent to another station, if the channel being used is “open”,
the remote station sends back a distinctive 4 tone revertive signal. The operator can
judge the quality of the channel for communications purposes by the strength and
clarity of this distinctive tone. Using Beacon Calls on several available channels will
determine which channel is best to use subsequent Selcalls or Telcalls
(Note:- both stations must be programmed for Selcall or Telcall operation)
Sending a Beacon Call
select the channel you think will be best to use (Refer to section
Overview of HF operation)
listen for traffic on that channel, if no traffic is heard then continue.
then press the key
select “Beacon Call” with the scroll keys
then press the key
enter the station ID of the station you wish to Beacon Call (see
“Entering station IDs and using the address and telephone
books”)
then press the key
wait for the Beacon Call to be sent.

call was successful.
If no revertive tone is heard or it was difficult to hear try another
channel and repeat the process until a good channel is found.
If a revertive tone is heard but you receive no verbal response
from the station it may be because the operator is unavailable at
the time.
43 of 285
Receiving a Selcall
To receive a Selcall your transceiver must be programmed for Selective Call
(Selcall) and where multiple channels are in use the scan function should be
activated.

Scanning Channels
Scanning allows a HF transceiver to monitor several channels for incoming calls. It
is particularly useful as the nature of HF signal propagation means that not all
channels are available for communications at one time. For instance, a station
calling a station that is in scanning can send a “Beacon Call” on any channel
knowing the station it is calling is monitoring all its available channels. A response
from the scanning station will only occur on channels that are “open” for
communication.
Stations in scan can also monitor channels for voice activity or signals received that
has a signal strength over a preset level.
Selcall Scan
When a Selcall signal is detected, and the channel has Selcall enabled, no matter
which mute type is selected the transceiver will stop scanning and decode the
Selcall. The transceiver will only stop scanning when a Selcall is detected.
Signal Strength Scan (SSL Scan)
If the signal strength mute (squelch) is active and a signal with a level greater than
the pre-set threshold is received the scan will halt. Scan will remain halted while the
signal level stays above the preset threshold. Once the signal decreases below the
pre-set threshold level, for a period greater than the scan dwell period, scanning will
resume.
Voice (Syllabic) Scan
If the audio mute (squelch) is active and is opened scanning will halt. Scanning will
remain halted while the audio mute is open. Once the mute closes, for a period
greater than the scan dwell period, scanning will resume.
The Barrett PRC-2090 transceiver has up to eight scan tables available each table
being able to be programmed with up to thirty channels. (See Menus and
Programming for details on channel entry)
57 of 285
Selecting a Scan Table
press the key for more than two seconds
use the scroll keys to select the scan table number
then press the key
Note:- If no scan tables are programmed the following is displayed:-
Initiating Scan
Momentarily press the key.
Alternatively scan may be programmed as a default condition so when the
transceiver is switched on, scan is automatically initiated, or after a period of
inactivity, i.e. no key presses, the transceiver returns to scan.
58 of 285
Clarifier
The clarifier is used to finely tune the receiver on the selected channel to
compensate for received signals from other stations that are off frequency.
The receiver can be tuned in the clarifier mode in steps of 1 Hz to frequencies up to
-1 kHz and +1 kHz of the assigned channel frequency, depending on programming.
(see note below)
to enter clarifier tune mode.
or tune clarifier up
or tune clarifier down
Note:- There are five clarifier ranges available, these ranges can be set either when
programming the transceiver or in the “RF Settings” section of the protected
menu.
Note:- The clarifier value is set to zero when the channel is changed or the
transceiver is turned off.

external ESU…Encryption Synchronisation Unit.
Note:- The external ESU must be connected and providing valid data for the
frequency hopping system to operate
Selecting the Hop Band
Select the channel used for normal/clear transmissions based on the normal
procedures used when using an HF system, this channel frequency and mode is
used by the Barrett PRC-2090 to determine the hop band. .
Note:- The reference frequency in NOT a centre frequency for the hop band. It
simply determines which of the preset hop bands are selected.
Entering the Security Code
For hopping PIN code entry refer to the “General” section of the Protected Menu, in
the subsection “Hopping PIN”, select the security PIN code based on the
information below.
Security Codes and Bandwidths
Security codes 00000000 to 19999999 are used for hopping +/- 2 kHz
Security codes 20000000 to 49999999 are used for hopping +/- 16 kHz
Security codes 50000000 to 99999999 are used for hopping +/- 128 kHz
Note:- Hopping up to +/- 2 kHz is useful for narrow band antennas such as when
using antenna tuners in manpack operation.
Note:- Hopping up to +/- 128 kHz can be used with wideband antennas such as
base station broadband antennas.
Note:- Once entered the security code for security reasons can never be retrieved
or viewed.

167 of 285
Security Code Management
Changing the Hop Code
It is advisable to change the 8-digit hop code (for the entire hop network) on a
regular basis.
The frequency of code change with a network is entirely dependant on the situation
that exists at the time.
Code Distribution
Code distribution will be the same as for any other direct entry crypto devices - i.e.
this is a logistics issue for the person/organisation administering the hop network.
Network Planning and Contingencies
As the Barrett 2000 series frequency hopping system has a GPS based
synchronisation system that requires no master station allocation, operating the
system requires the minimum of communications strategies.
The network users have only to be briefed on the channel and security codes to use
the system.

Automatic Link Establishment (ALE) (Option)
ALE System Overview
The Barrett Automatic Link Establishment (ALE) controller option simplifies the
operation of HF networks, the ALE option automating many of the procedures
necessary to establish and maintain an HF link.
The Barrett PRC-2090 ALE controller option provides complete inter-operability as
required by FED-STD-1045 and U.S. MIL-STD-188-141B standards.
HF network stations equipped with ALE controllers automatically scan a pre-
selected set of channels, listening for ALE calls. If sounding is selected stations at
periodic intervals send out “sounding calls” to other stations. These signals are
analysed for link quality and stored in the “sounded” stations. All stations gradually
build up a table of parameters which determines best channels to use to link
between specific stations. These tables are used by the ALE controller to determine
the best channel to connect on when commanded by its operator to communicate
with another station.
The Barrett PRC-2090 ALE controller’s powerful memory stores up to 10,000 sets
of LQA information, 100 channel configurations, 20 self-address configurations and
100 other address configurations.
Operation Overview
The ALE network parameters are determined by a network supervisor, this person
programs all the transceivers in the network with the required addressing and
channel information using the ALE fill program. This is a PC based program used to
transfer pre-determined network information into each transceiver. A separate
manual is provided as a guide to ALE network setup and for the operation of ALE fill
program. As ALE’s prime purpose is to automate many of the procedures
necessary to establish and maintain an HF link, it is only necessary for the operator
to enter the station he wishes to call and activate ALE call sequence as described
in the following section.
Within the protected menu ALE section various operational parameters can be
changed as required by the operator. The section titled “ALE menus” describes
these functions.

Combined ALE / Selective Call Capability
Overview
The combined ALE / Selective Call capability allows the user to receive and
transmit ALE and Selcall type calls on channels which are programmed for ALE
scan but also have Selcall enabled on them. This means that during ALE channel
scanning the transceiver can accept incoming Selcalls. However, this feature can
only be used if the ALE scan rate is set to 2 channels per second (set in the
“2000 Series Programming Software”)
To Commence Scanning
Note:- You should have selected the required scan list before you commence
scanning, refer to the section “ALE scan list select” in the ALE protected menu.
Press the key
the PRC-2090 transceiver will now be ALE scanning and ready to
accept ALE calls, receive “Soundings” and transmit “Soundings”
(If “Sounding” is enabled on your transceiver)
The PRC-2090 transceiver will also be able to decode incoming
Selcalls as long as 2 channels per second is set as the ALE scan
rate and Selcall is enabled on the scan channels. Selcall
decoding is handled just like it is when the transceiver is in
standard non-ALE scan mode.
During ALE scanning the following messages may be displayed:-
This occurs when your station receives an ALE sounding from
another station in the network.
