10 of 285 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.
11 of 285 About this Operating and Installation Manual This manual is comprehensive, describing all aspects of the transceivers functions and should be viewed as a reference manual. A separate abbreviated Quick Reference Guide card with primary functions is also supplied with each transceiver and should be kept at the operating position of the transceiver.

13 of 285 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.

16 of 285 When Using the Handset:- Press and hold down the PTT (transmit) button only while talking Hold the microphone close to your mouth Speak clearly Use the word ‘over” to indicate you have finished speaking and release the PTT (transmit) button. 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.

29 of 285 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.
31 of 285 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 self ID is not set during the call procedure or the Selcall address book entry being used does not have a self ID attached to it. These IDs are also used when making calls via the RS232 control command set. Setting Default Self IDs then press the key. Use the scroll keys to select the self id to attach to the default ID (in this case the 4 digit OEM defalut ID) then press the key. Repeat the steps above for each default ID.

41 of 285 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. listen for the distinctive 4 tone revertive signal from the station you have called. If no revertive call is heard or it was difficult to hear try another channel and repeat the process until the best channel is found.
42 of 285 Receiving a Beacon Call When a transceiver receives a beacon request call, it responds by transmitting the Beacon Call revertive tones. No indications occur on the transceiver. Beacon Calls are not saved in the Selcall history buffer. Sending a Selcall select the channel you want to send the Selcall on. (“Beacon Call” can be used to select the best channel) listen for traffic on that channel, if no traffic is heard then continue then press the key select “Selcall” with the scroll keys then press the key enter the station ID of the station you wish to call (see “Entering station IDs and using the address and telephone books”) then press the key wait for the Selective Call to be sent. listen for revertive tone from the called station that indicates the 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. Receiving a Selcall Directed to Your Transceiver When you receive a Selcall, your station sends a revertive call (to alert the calling station that its call was received), an audible alarm is sounded, the mute (squelch) (if selected) opens and the display shows the call as follows:- The audible alarm will sound for thirty seconds and then time out. To cancel the alarm before the time out period and to acknowledge the call, press PTT or any key.

56 of 285 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)

165 of 285 Frequency Hopping (Option - Export Permit Required) The Barrett PRC-2090 employs a unique frequency hopping system that uses an 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.
166 of 285 To Enable Hopping Mode Press the key for more than two seconds As soon as this display is shown you can start communicating with other stations using the same channel frequency and having the same hopping code entered. To Disable Hopping Mode Press the key for more than two seconds Note:- The external ESU must be connected and providing valid data for the frequency hopping system to operate.
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.
168 of 285 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.
