Page 8: Barrett 2090 Compliance
EN60950-1:2002 FCC RF Exposure Compliance Statement The Barrett 2090 HF Transceiver has been tested and complies with the Federal Communications Commission (FCC) RF exposure limits for the General Population/Uncontrolled exposure environment. In addition, it complies with the following Standards and Guidelines:...
Page 9: Fcc Rf Exposure Warning
ICNIRP Exposure Guidelines (1998) for occupational exposure. Safe working distance can be reduced with normal voice communication. For FCC compliance, when the 2090 transceiver is used at a power level of 125 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.
Page 10: About This Operating And Installation Manual
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.

Page 28: Barrett Selective Calling System
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 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.
Page 29: Selective Call –"Selcall
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.
Page 30: More Selective Calling Information
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.
Page 31: Default Self Ids
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.

Page 40: Checking For The Best Channel To Use Between Two Stations - Beacon Call
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.
Page 41: Receiving A Beacon Call
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.
Page 42: Receiving A Selcall
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.

Manpack Operation Using the Automatic Antenna Tuner The 2090 manpack can be used with the 10 metre throw over long-wire provided or the optional 3 metre collapsible whip. Note:- Either the whip or the long-wire can be used but not both together.
Page 228: Using The Emergency Long Wire Antenna (P/N 2090-02-06)
Using the Emergency Long Wire Antenna (P/N 2090-02-06) The long-wire antenna should be unfurled and the end away from the manpack transceiver should be attached to any structure available and as high as possible. Note:- When using an un-tuned antenna such as the whip or the long-wire the section “Antenna Select”...

Page 230: Operation Of The 2090 Manpack In Temporary Base Stations
Operation of the 2090 Manpack in Temporary Base Stations For temporary base station operation, the Barrett 2090 can be operated using either a broadband antenna Barrett P/N BCA209006 or a tunable wire dipole, Barrett P/N BCA209007. Rapid Deployment Broadband Dipole Antenna - 40 W (2090-02-03) The Broadband Dipole Antenna is a dipole antenna with loading to allow broadband operation.
Page 231: Rapid Deployment Broadband Dipole Antenna Configurations
Rapid Deployment Broadband Dipole Antenna Configurations Horizontal Dipole The horizontal dipole has maximum gain on the broadsides of the antenna and reduced gain along the axis. Height above ground affects radiation angle. Lower heights give higher angle radiation, better for NVIS (short distance). Higher heights give lower radiation angle, better for long distance communication.
Page 232: Sloping Dipole
Sloping Dipole Radiation with the Sloping Dipole becomes more directional, with increased gain in the direction of the lower end of the antenna, and reduced gain towards the higher end. Inverted U The inverted U has a radiation pattern between that of horizontal dipole and inverted V.
Page 233: Rapid Deployment Dipole Antenna - 40 W (2090-02-01)
Rapid Deployment Dipole Antenna - 40 W (2090-02-01) The Rapid deployment tunable wire dipole is a tuned antenna with frequency labels to indicate tuned lengths. For operation, each side of the antenna is unwound to the tuned length for the frequency required. For operation at a labelled frequency, the label should be level with the end of the winder as shown in the picture below.

Rapid Deployment Dipole Antenna Configurations Horizontal Dipole The horizontal dipole has maximum gain on the broadsides of the antenna, and reduced gain along the axis. Height above ground affects radiation angle. Lower heights give higher angle radiation, better for NVIS (short distance). Higher heights give lower radiation angle, better for long distance communication.
Page 235 Sloping Dipole Radiation with the Sloping Dipole becomes somewhat asymmetrical, with increased gain in the direction of the lower end of the antenna, and reduced gain towards the higher end. Single Ended For rapid deployment, with reduced but still acceptable efficiency, the antenna can be operated single ended.

Note:-Should the Barrett 2090 be operated inside a bunker or building an 8 meter GPS extension cable P/N 2090-01-23 is available to mount this module outside in view of the satellites.
Page 241: Overview Of Hf Operation
Overview of HF Operation HF (High Frequency) is the radio spectrum with frequencies between 1.6 and 30 MHz. Within this radio spectrum an efficient form of transmitter modulation, SSB (Single Side Band), is used. This, combined with the use of the ionosphere - a layer of ionisation gases that resides between 100 and 700km above the earth’s surface, provides efficient, cost effective communications over short, medium and long distances - without the need for expensive re-transmission devices, such as the...
Page 242: Radio Wave Propagation Illustrated
Radio Wave Propagation Illustrated The following illustrations show the characteristics of ground-wave and sky-wave propagation during day and night time. In each illustration the height of the ionosphere above the ground is shown. In both illustrations Station A communicates with Stations B, C and D. Propagation from Station A to B is by ground-wave.
Page 243: Night
Generally speaking the greater the distance over which you want to communicate, the higher the frequency you should use. Beacon Call, a Selcall (Selective Call) function built into the Barrett 950 transceiver, makes finding the correct frequency to use easy. Beacon Call is based on the network transceivers all having a selection of frequencies that will accommodate most ionospheric conditions.
