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 example,
the microphone becomes jammed between seats in a vehicle causing the PTT
(transmit) switch to be held down. 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 Settings menu. See page 93.

BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Selective Call - Selcall
Selcall (selective calling) is a digital signalling system based on the standard
CCIR-493 for use on HF networks. It is a type of squelch protocol used in
radio communications systems, in which transmissions include a brief burst of
sequential audio tones. Receivers that are set to respond to the transmitted
tone sequence will open their squelch, while others will remain muted.
Selcall Self IDs
Each station in an HF network can be assigned up to 14 different Self IDs of
ZKLFKWKHUHFDQEHDPL[WXUHRIIRXURUVL[GLJLW,'V LGHQWLĂFDWLRQ $VWDWLRQ
can be called using any of these Self IDs.
Selcall Decode
The Transceiver has the ability to decode both OEM and International Selcalls
on any channel programmed as a Selcall channel. However, the call must be
addressed to the relevant ID (OEM or International).
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

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.
Selective Call - Telcall
Telcall uses this digital Selective Call system to send 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 PSTN.

use encryption.
Four and six digit GPS and Status data calls use the OEM privacy key to encrypt
the data. If this eight digit key has not been programmed by the Barrett 4050
HF SDR Programming Software (P/N BCA40001), a default privacy key of
99999999 is automatically used for transmission.
Six digit Page calls 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.
Emergency GPS calls are automatically sent as plain text (four and six digit).
Station ID Ranges
The standard Selcall system accommodates four and six digit networks.
Station IDs range from 000000 to 999999 inclusive (the destination ID must be
either four or six digits long).

Beacon Call
A Beacon Call checks for the best channel to use between two stations. It
allows the Operator to determine the signal quality between their station and
the 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, and if the channel being used is
open, the remote station sends back a distinctive four-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 either subsequent Selcalls or Telcalls.
Note: both stations must be programmed for Selcall or Telcall operation.

operation of HF networks by automating many of the procedures necessary to
establish and maintain an HF link.
The ALE controller option provides complete inter-operability as required by
FED-STD-1045 and U.S. MIL-STD-188-141C 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 will send out sounding calls to other stations at
periodic intervals. These signals are analysed for link quality and stored in the
sounded stations. All stations gradually build up a table of parameters which
GHWHUPLQHWKHEHVWFKDQQHOVWRXVHWROLQNEHWZHHQVSHFLĂFVWDWLRQV7KHVH
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.

ALE Set-up Overview
The ALE network parameters are determined by a network supervisor. The network supervisor programs all the Transceivers in the network with the required
addressing and channel information using the Barrett 4050 HF SDR ProgramPLQJ6RIWZDUH 31%&$ SULRUWRĂHOGXVDJH
The Barrett 4050 HF SDR Programming software (P/N BCA40001) is used to
transfer pre-determined network information to each Transceiver.
As ALEâs 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 desired station to call and activate the ALE call sequence as described in
this section.
Various operational parameters can be changed within the protected menu
ALE section as required by the Operator. The ALE Settings section on page 101
describes these functions.

Combined ALE / Selective Call - 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 Barrett 4050 HF SDR Programming Software (P/N BCA40001)).

LQA Averaging
This option sets the method used to update an existing link quality value stored
in ALE processor memory when the new link quality value is worse than the
stored value.
The option can be set to either replace the old values with the new values or
replace the old values with different weighted averages of the old values and
new readings.
Averaging reduces the effect that one bad reading might otherwise have on a
perfect channel. If a new reading is better than an old value, the old value is
replaced by the reading. There are four different averaging formulas available:
Tap /4$$YHUDJLQJ from the ALE

Hop
This option requires an Export Permit.
The Transceiver 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 a channel which is used for normal / clear transmission based on normal
procedures used when using an HF system. This channel frequency and mode is
used by the Transceiver to determine the hop band.
Note: The reference frequency is 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 SDR Options and Option PINs on page
113. The security PIN code is based on the information below.
Security Codes and Bandwidths
Security codes 00000000 to 19999999 are used for hopping Âą 2 kHz
Security codes 20000000 to 49999999 are used for hopping Âą 16 kHz
Security codes 50000000 to 99999999 are used for hopping Âą 128 kHz
Hopping up to Âą 2 kHz is useful for narrow band antennas such as when using
antenna tuners in manpack operation.
Hopping up to Âą 128 kHz can be used with wideband antennas such as base
station broadband antennas.
Once entered, the security code for security reasons can never be retrieved or

Scan
Scanning allows the 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 example, a
station calling a station that is in scanning mode 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.
The Transceiver will stop scanning for the following reasons:
â˘
Signal Strength Level (SSL) mute is selected and a signal with a level
greater than the pre-set threshold is received.
â˘
Audio (syllabic) mute is selected and a voice signal is detected.

To stop scanning, press
See page 72 for setting the attributes for scanning.
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.
See page 77 for information on the SSL pre-set threshold and page 73 for
information on the scan dwell period.
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.

Site Selection Recommendations
The success of every HF Radio system is primarily measured by its ability to
UHFHLYHZHDNVLJQDOVDQGWRWUDQVPLW5)SRZHUHIĂFLHQWO\$QXPEHURILPSRUtant factors need to be considered to achieve success. These include: frequency
selection, time of day and ambient noise at the receiver site. Frequency and
time of day are factors which can be used to calculate the maximum usable frequency (MUF) and lowest usable frequency (LUF), for a particular time of day,
using prediction software freely available on the internet. A typical example of
this is VOACAP, http://www.voacap.com/prediction.html
Site selection and system design go hand in hand and should be considered
before any equipment is purchased. Forcing the radio system into an unsuitable site will undoubtedly result in disappointing if not unworkable performance
of the system. Little can be done to improve an installed system if, for example,
the ambient RF noise is unacceptably high.
It is recommended that site evaluation be done before any system designs are
ĂQDOLVHGWRDYRLGV\VWHPSHUIRUPDQFHGLVDSSRLQWPHQW
The following should be considered when choosing a position for the Transceiver:

Proximity of
Transceiver to
Antenna
When using RG-58 coaxial cable from the Transceiver to the
antenna, a cable length of no more than 30 metres is recommended. Should a run of more than 30 metres be required, it
is recommended that a low loss coax such as RG-213 or RG-8
be used.
It is recommended that the Transceiver chassis is connected
to ground using the bolt on the rear panel to stop pick-up
of unwanted noise from local power supplies and electrical
equipment.
160
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Power Supply
When 12 V DC is supplied to the 4050 Transceiver, the PEP Voice output power
will be restricted to 125 W. Conversely, when 24 V DC is supplied to the 4050
Transceiver, the PEP Voice output power will achieve 150 W.
Power output regulation is done automatically based on the DC voltage presented to the Transceiver DC input connector. The Barrett 4022 Power Supply is
available in two versions, the BC402200 (12 V DC) and the BC402201 (24 V DC)
version. Each power supply version is capable of operation with AC mains input
voltage between 88 and 256 V AC.
In base station installations where no mains supply is available, various Barrett

This noise causes a static type of interference in the receiver. It may be necessary,
WKHUHIRUHWRVZLWFKRIIWKHEDWWHU\FKDUJHUZKLOVWWKH7UDQVFHLYHULVLQXVH,IĂRDW
charging of batteries is required for installations with unreliable AC power supply,
it is recommended that a Barrett BC402200 or BC402201 be used as each provides a three stage charge facility to maintain a battery without the noise problem
described above.
Voltage Drop
The average current consumption of the Transceiver is low but during transmission of voice peaks, high current is needed for short intervals. This means that
the power supply cable must be heavy enough to supply these short duration
current peaks without excessive voltage drop. Preferably, only use the power
cable supplied with the Transceiver. If extra cable is required, use a cable with a
conductor square area of no less than 8 mm2. Unwanted voltage drop will also
occur if incorrect wiring techniques such as poor choice of connection points
and incorrect use of terminal lugs are used.
Protection Fuse
The Transceiver is provided with adequate internal protection. However, the

7UDQVFHLYHULWVHOIEXWWRHQVXUHWKDWLQWKHHYHQWRIGDPDJHWRWKHFDEOHDĂUH
risk does not exist. The fuse used must be installed in the active wire as close as
possible to the battery, and must be of a type which has a low voltage drop at
the peak currents expected.
161
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Note: In-line 3AG glass fuses are not suitable. An ATC automotive blade type fuse
rated at 25 A with a suitable high current ATC fuse holder rated at 30 A or more
should be used. These type of fuses and holders are contained in our standard
installation kit (Barrett P/N BCA40004) or are available individually (Barrett P/N
BCA20021).
Antenna
The antenna is a most critical part of the complete radio installation. It must
accept the output power from the transmitter, radiate that power with
minimum loss and in the receive mode, accept weak signals for input to the
receiver.

can be used for base station installations, using the Barrett 911 automatic
antenna tuner. However, the following points should be considered:
The antenna should be mounted as far away as possible from buildings, trees,
vegetation and sources of electrical interference. If metallic masts or supports
are used, arrange insulators to ensure the antenna is spaced at least two
metres from the mast. Remember the radiating part of the antenna starts at
the tuner. The location of the bottom portion of the antenna is very important.
Horizontal wire antennas have maximum radiation broadside to the antenna
when the frequency is less than Âź wavelength. Radiation is at a minimum at
the end points of the antenna. Inverted âVâ installation of horizontal antennas
minimises the directivity and is recommended for omni-directional coverage.
High voltages are present on the antenna system. The antenna tuner and
antenna should be located or protected so that there is no possibility of accidental contact.
Transceiver and Tuner Mounting
The Transceiver should be mounted in a suitable position allowing easy
operator access. The antenna tuner should be mounted, preferably out of the
weather, and as close to the ground (earth) point as possible. The interconnect
cable supplied with the antenna tuner should be routed, away from other
cables, back to the Transceiver and connected as indicated in the diagram. The
maximum interconnect cable should be less than 25 metres.
173
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Ground (Earth) System
The ground (earth) system is a key part of the overall antenna system and consequently the system operation. An inadequate ground system is the primary
cause of poor performance and tuning problems. There is little point in installing the antenna unless a good ground system can be provided. In areas of
good ground conductivity (i.e. ground always damp), an effective ground can
be made through a grounding rod. This should be approximately three metres
in length and should be installed as close to the tuner as possible. Several rods
bonded together will improve the ground contact. In some cases metal water
pipes may be used as a ground providing:
â˘
The water pipe is close to the tuner and the water pipe enters the ground
close to the tuner.
â˘
There are no joints or couplings in the pipe that will increase the resistance path to ground.
â˘
The water pipe enters soil with good conductivity.
â˘
A low resistance joint is made with the water pipe.

well drained sandy soils or on rock. In these cases, a counterpoise must be used
as a ground system. This will also be the case in rooftop installations where no
H[LVWLQJJURXQGSODWH VXFKDVPHWDOURRĂQJH[LVWV
The number of radials required for an effective counterpoise depends on the
soil quality, dampness and other factors which affect the conductivity of the
soil. The more radials used, the better will be the performance of the antenna
/ ATU combination especially at lower frequencies. This manual suggests a
minimum of 20 radials, but optimum performance at low frequencies is not
guaranteed.
The radials of the counterpoise need only be of much thinner cable i.e.
5.48mm2 (#1 #2 SWG) preferably copper wire. RG58 Coaxial cable may be
used. At the base of the antenna, the radials all couple together at a common
well bonded antenna ground point. The radials should be buried into the
ground to a minimum of 200 mm depth.
Note: To accomplish reliable ATU tunes at frequencies below 5 MHz, it is not
uncommon, with poor conductive soil conditions, to require up to 120 radials each
of up to 70 m length, requiring thousands of metres of cable and a lot of trenching.
This is impractical and is the reason we do NOT recommend Whip / ATU antenna
for land based systems.
174
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Electrical Checkout
After mechanical installation is complete, select the highest frequency to be
used on the Transceiver. A directional watt-meter such as a Bird model 43 may
be inserted in the coaxial transmission line between the Transceiver and the
tuner, although the internal metering of the Barrett 4050 Transceiver is adequate. The tune mode on the Transceiver is then energised. Upon application
of RF energy, the tuner should start to tune, indicated by the âclatteringâ of
the tuner relays. After a few seconds the relay noise will cease, the Transceiver
should indicate a successful tune and the watt-meter, and front panel indicaWLRQRIWKHVKRXOGVKRZDORZYDOXHUHĂHFWHGSRZHUFRQVLVWHQWZLWKD
VSWR of better than 2:1. Now select the lowest desired frequency on the Transceiver and repeat the above procedure. The result should be the same, except
that the tune cycle may take somewhat longer. If the above procedure does not
give the results indicated, check that the antenna length and connections are
correct and re-check all ground (earth) connections.
Note: When received, the Barrett 911 automatic antenna tuner memory system will
usually not have any pre-stored tuning information appropriate to your installation.
To allow the 911 to âlearnâ its tuning information, simply proceed from one channel
to the next allowing the normal tune cycle to take place. Each successful tune is
âmemorisedâ so that when that channel is re-selected the tuner will almost instantaneously retune to that frequency.

Site Selection Recommendations
The following points must be considered when mounting the Transceiver.
Safety
It is essential that the Transceiver be mounted in a place where
it cannot cause injury to the occupants of the vehicle in the
event of a motor vehicle accident.
For this reason overhead mounting is not generally recommended and âunder dashâ mounting must take into account
the possibility of injuring the legs of front seat occupants.
Convenience The chosen position for the Transceiver or control head, (if a
remote controlled model is used) should be one which allows
convenient operation.
Positions which are often used are:
⢠On the transmission hump
⢠In place of the glove box
⢠Behind the seat
⢠Under the dash board (if safe).
Where a remote controlled Transceiver is used, only the control
head need be mounted convenient to the operator. The Transceiver may be mounted under a seat, in the luggage compartment or any other out of the way place within the vehicle
ZKLFKDOORZVIRUVXIĂFLHQWFRROLQJ
All equipment should be positioned in such a way that convenient access for maintenance is provided.
Strength
It must be assumed that the vehicle will be used on rough
roads and in many cases off road. Hence mounting of equipment must take into account the severe vibration and shock
that can be expected.
Transceivers may only be mounted to structural components
of the vehicle body and not on dress panels or plastic interior
panels. In some cases, the area around the Transceiver mounting may need reinforcement.

Obstruction
The installation of a Transceiver into a vehicle should not inhibit

pedals, gear change, hand brake etc. are not impeded, and that
heater or air-conditioning outlets, glove box and doors are not
obstructed. Always check that the drilling of mounting screw
holes will not damage electrical wiring, heater hoses or hydraulic lines.
Power Wiring
Connect the red positive and black negative wires from the Transceiver power
cable to the positive and negative terminal of the battery. Do not connect to
the ignition switch or internal fuse panels as vehicle wiring to these points is of

the vehicle chassis then it is important to connect the radioâs negative
supply cable to the chassis side of the isolation switch.
Earthing
Ideally the radio should be mounted as close as possible to the antenna with
a common earthing point being used for both the antennaâs earth connection
and the radioâs earth connection.
181
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Antenna
In any radio system an effective antenna installation is essential. Because of the
QHHGWRUHGXFHWKHVL]HRI+)DQWHQQDVVRWKDWWKH\FDQEHĂWWHGWRDYHKLFOH
mobile antenna bandwidth becomes quite narrow and hence tuning is critical.
In most cases the only tuning adjustment that can be effected is adjustment to
position. Particular attention must be given to the antenna position if satisfactory performance is to be obtained. Refer to the instructions supplied with the
antenna you have selected.
Antenna Mounting
The antenna mounting must provide a strong secure anchorage for the base
of the antenna. To obtain maximum radiation, the antenna base must be
well bonded electrically to the vehicle chassis. Paint, dirt, rust, etc. should be
UHPRYHGIURPWKHUHVSHFWLYHĂ[LQJSRLQWV7KHPRXQWLQJSRLQWPXVWSURYLGHD
low resistance electrical path to the main vehicle metallic structure.
Antenna Feed Cables
Antenna feed cables should be run (as far as possible) away from other vehicle
wiring and especially away from ignition high tension wiring. Where passing
through body panels or internal bulkheads, grommets must be used to protect
the cables. Water-proof connectors must be used when they are outside the
vehicle.
Voltage Standing Wave Ratio (VSWR)
After installation it is recommended that the VSWR of the antenna should be
measured for each channel. The instructions supplied with each antenna will
detail this operation.
Noise Suppression
Please note that some newer fuel injected engines emit very strong EMI
(Electromagnetic interference) noise levels across the HF radio band, which is
near impossible to suppress. For these installations, moving the position of the
antenna to another position on the vehicle may reduce the noise effect but full
elimination of noise during engine running may never be achieved. Please note
that this is not unique to the Barrett 4050 radio as all radio makes will suffer
similarly from the effects of this noise under these conditions.
182
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Noise generated by motor or electrical accessories on the vehicle may cause
objectionable interference to the received signal. This noise enters the receiver
either by means of the battery leads or the antenna system. Providing that the
recommendations concerning battery wiring given earlier in this manual are
IROORZHGQRLVHLQMHFWHGYLDWKHEDWWHU\OHDGLVXQOLNHO\WREHVLJQLĂFDQW0RVW
noise problems result from pick-up by the antenna. Practical cures involve
either preventing the noise from being generated or minimising it from being
radiated by the wiring connected to the noise source.
Interference Suppression Kit
(Barrett P/N BCA20008) is available to assist in noise suppression and contains

The techniques involved in noise suppression include re-routing of wiring,

equipment in good working order as worn brushes, loose connections and the
like, will increase the amount of noise generated.
Before attempting to cure a noise problem, the source (or sources) of noise
PXVWEHLGHQWLĂHG,GHDOO\WKHUHVKRXOGEHQRGLIIHUHQFHEHWZHHQEDFNJURXQG
noise in the receiver with motor and accessories on and that with motor and
accessories off.
If a detectable difference does exist, turn off all accessories one by one until
a change in noise results. Continue, noting each contributing unit until there
is no detectable difference from the âall offâ noise level. (For accessories such
as alternator, motors, instruments etc. a wire or drive belt may have to be
temporarily removed for this assessment.) After identifying each noise source,
they can be worked on one at a time until an acceptable level of suppression is
achieved.
Another approach to this problem is to remove or disconnect all possible
sources of noise then replace and suppress them in turn.
Some suggestions for suppressing particular noise sources follow:
183
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Ignition Systems
All high tension wiring from the ignition coil through to
the spark plugs should be kept as short as practicable,
clean, and as close to the engine block as possible. The
cable should be an impregnated neoprene resistive type
and the coil must be either mounted on, or immediately
adjacent to, the engine block. The low tension wire from
the coil to the distributor contact breaker points must be
as short as possible, and not included with other wires in
a harness or loom. This wire must be shielded if more than

BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Engine Instrumentation
Certain types of oil-pressure sensors and voltage regulators
used in instrument systems contain a vibrating or thermal
cycling contact. These devices can only be suppressed
by isolating and screening or wiring in the same way as
described for the alternator to regulator control wire. Disc
ceramic capacitors with short leads (protected with insulating sleeving) are frequently useful but to prevent damage
to instrument contacts, where the use of bypass capacitors

â˘
Petrol engine ignition noise and contact breaker noise is a sharp staccato
âplopâ varying with engine speed. It is only with this class of noise that the
impulse noise limiter incorporated within some Transceivers is effective.
â˘
Noise from other sources generally has a more âmushyâ sound. That from

battery.
â˘
The noise from instrument regulators may depend on the battery voltage,
the reading of the instrument and the length of time the system has been
switched on. For this reason, the search for noise sources must be done
thoroughly to prevent noise from apparently reappearing after the installation has been completed.
â˘
Electric motors generate a âwhiningâ sound. Do not forget to check windscreen wipers, electric fuel pumps, heater and air conditioning fans and
other motors which operate only on an intermittent basis.

2019 Automatic Tuning Mobile HF Antenna
(Barrett P/N BC201900)
The Barrett 2019 automatic tuning mobile HF antenna plugs directly into the
rear of a 4050 Transceiver using the cables supplied.
Important: 4050 Transceivers must have the 2019 antenna option set during programming.
Mounting the Barrett 2019 Automatic Tuning Mobile HF Antenna
The Barrett 2019 antenna should be mounted in positions similar to those
illustrated in the diagrams on the following pages. Select a position free from
excessive vibration. A bracket, fabricated to withstand the forces and vibration
that can be expected during off-road driving, should be used to mount the
antenna to the vehicle. When locating the mounting position for the antenna
HQVXUHWKDWWKHDQWHQQDERG\ZKHQĂH[LQJRQLWVYLEUDWLRQPRXQWFDQQRW
come into contact with other parts of the vehicle. The antenna should be
mounted as far from surrounding objects on the vehicle as possible.
The antenna is supplied standard with two sections (Barrett P/N: BCA201901),
a tapered black spring (Barrett P/N: BCA201903), an antenna installation guide
and a pre-terminated six metre control cable to suit the Barrett 2019 antenna
to Transceiver. A six metre (Barrett P/N: BCA201904) or ten metre (Barrett P/N:
BCA201905) extension cable for the control cable is also available.
The control cable should be routed into either the engine compartment or boot
(trunk) of the vehicle. If the joint between the antenna control cable and the
extension cable is in an exposed position, a butyl rubber self amalgamating
tape should be used to seal the joint. Do not wrap this joint if it cannot be
made completely water tight as water will collect in the joint and cause it to
corrode.
$JRRGHDUWK JURXQG WRWKHPDLQERG\RIWKHYHKLFOHLVHVVHQWLDO
IRUHIĂFLHQWRSHUDWLRQRIWKHDQWHQQD To achieve this clean all joints to

BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
914 Series Manual Tap Whip Antenna
(Barrett P/N BC91401 to BC91424)
Installation
914 series manual tapped whip antennas are mounted on vehicles using
a heavy duty base and spring (Barrett P/N BCA91400). The whip should be
mounted on the vehicle in positions such as those illustrated in the diagrams
below. A bracket, fabricated to withstand the forces and vibration that can
be expected during off-road driving, should be used to mount the antenna
base and spring to the vehicle. When locating the mounting position for the
antenna, the ring located above the label at the bottom of the whip should be
level with the surrounding ground plane, e.g. the bonnet of the vehicle or the
roof of the vehicle. Ensure that the mounting bolt on the base and spring is
electrically bonded to the chassis of the vehicle via a very low resistance path,
i.e. clean all joints to bare metal and use braid earth straps if any non-metal
joints are encountered. Use only good quality coaxial cable and water proof
UHF connectors (such as those supplied by Barrett Communications).
'RQRWXVH3/ 8+)FRQQHFWRUV.
When running the coaxial cable from the antenna to the Transceiver, avoid
sharp corners and heat such as that generated by the manifold of the engine.
After installing the antenna check the antenna VSWR on each channel. Generally if the antenna has been mounted in the positions as illustrated, the VSWR
will be less than 1.6-1 and no adjustment is necessary. If the VSWR is not lower
than 2:1 the antenna to ground capacitance in that installation is probably
outside of the design range of the factory set tuning. Consideration may be
given to retuning the whip if the VSWR is so high as to cause the transmitter
ALC system to begin to reduce power (to protect the transmitter).
193
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
For each frequency which will not tune correctly you will need to determine
whether the tuning is high or low in frequency. Generally any frequencies
which will not tune will always be out the same way. When the antenna is
manufactured, most frequencies are deliberately made on the low frequency
side and adjusted upwards by the placement of âtuning ringsâ. Tuning rings
are single short circuit rings of 20 amp fuse wire placed on the windings of an
individual part of the antenna. A tuning ring inductively raises the frequency of
the section of antenna over which it is placed.
It must be understood that the tuning of an antenna on a particular vehicle
or installation may not hold for other vehicles or installations. To determine
whether any particular frequency tap is high or low, hold the tune key down
on the relevant frequency and observe the VSWR on a suitable meter. Get an
assistant to slowly move his outstretched arm closer to the antenna tap in use.
If the VSWR gets better, then the
antenna is too high in frequency. This
LQGLFDWHVWKDWWKHUHLVLQVXIĂFLHQW
antenna to ground capacity. Usually
this happens when the antenna is
mounted too far away from the body
of a vehicle. Either re-site the antenna
closer to the vehicle or remove any
tuning rings which are already on the
antenna.
If the VSWR gets worse when following the above procedure ,then
too much capacity is already present.
This is frequently encountered when
mounting the antenna too low on a
vehicle bumper bar or when mounting close to bodywork as in cab-over
type vehicles. In this case, either resite the antenna further away or add
extra tuning rings to the frequency
sections affected until a suitable
VSWR is obtained.
If the highest frequency on the whip
requires adjustment, initially place
the tuning ring here and slowly move
upwards until a satisfactory SWR is
obtained.
,IWKHIDFWRU\WXQLQJULQJLVQRWĂWWHG
and the highest frequency on the whip
requires adjustment, initially place
the tuning ring here and move slowly
upward until a satisfactory SWR is
obtained.
If ONLY the lowest frequency requires
adjustment, initially place the tuning
ring here and slowly move upwards
until a satisfactory SWR is obtained.
Note: Truck cab-over installations usually produce distorted radiation patterns even
when the VSWR looks good.
When tuning is complete, any new rings added should be coated with epoxy
resin to secure and protect the ring from damage. Five minute quick setting
type epoxy is suitable. If rings need to be removed they may be cut off using a
sharp pair of side cutters. Take care not to cut into the body of the antenna.

Operation Instructions
The 914 manual tapped whip antenna should now be screwed into the base
and spring mounted on the front of the vehicle.
The operation frequency being used on the Transceiver should now be selected
on the antenna. This is accomplished with the supplied jumper lead as indicated in the diagram below and the following example (Note: this is an example only and your antenna will be manufactured with different frequency taps.)
The 914 manual tapped whip antenna used in the example has the following
frequencies:
Channel 1 4030 kHz
Channel 2
4760 kHz
Channel 3 5190 kHz
Channel 4

Channel 9 10567 kHz
Channel10 14567 kHz
When using Channel 1, frequency 4030 kHz, the
jumper lead should be removed from the bottom
antenna socket and stored in the vehicle.
On all other channels the jumper lead is required:
For Channel 2, frequency 4760 kHz, the jumper is
plugged into the bottom socket then wound tightly around the antenna and the other end plugged
into the socket marked 4760.
For Channel 3, frequency 5190 kHz, the jumper is
plugged into the bottom socket then wound tightly around the antenna and the other end plugged
into the socket marked 5190.
And so on, to Channel 10.

Marine Installations
The Barrett 911 automatic antenna tuner is designed for use in land base
station and maritime HF services. Primarily designed for operation with endfed unbalanced antennas such as whips and long wires, the tuner is built in a
waterproof impact resistant, moulded ABS plastic enclosure.
Antenna Selection
The 911 automatic antenna tuner will operate into almost any end-fed antenna
with a length exceeding 2.5 metres, providing an effective ground (earth) is
XVHG7KHDQWHQQDHIĂFLHQF\ZLOOEHSURSRUWLRQDOWRWKHOHQJWKRIWKHDQWHQQD
and will be maximum when the length of the antenna approaches Ÿ wavelength. It is advisable to limit the wire antenna to Ÿ or ž wavelength at the
highest frequency to be used.
198
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Antenna
On sailing vessels the antenna can either be an insulated backstay or a whip
antenna mounted vertically, usually on the stern. Best performance will be
achieved by using an insulated backstay as the radiating length will be longer
than that available when using a whip. The top insulator on the backstay
should be approximately 300 mm from the mast and the bottom insulator
should be at eye level above the deck. The distance between insulators should
be greater than 10 metres and less than 35 metres. A whip antenna is generally
used on small to medium sized power vessels. There are different length whips
to suit the vessel length.
Transceiver and Tuner Mounting
Select a suitable position in the vessel to mount the Transceiver. It should be a
position that is out of the weather and easily accessible to the operator, whilst
as close as practical to the 13.8 V DC power source. Mount the Transceiver to a
VROLGĂ[LQJSRLQWXVLQJWKHPRXQWLQJFUDGOH0DNHVXUHWKHUHLVVXIĂFLHQWVSDFH
at the rear of the Transceiver to connect the power and antenna cables.
The antenna tuner should be mounted as close to the antenna feed point as
possible. In metal vessels the length of the feeder from the antenna tuner to
the feed-through insulator, inside the vessel, should be kept less than 1 metre.
The antenna feed cable should be a suitable high voltage cable. Care should
be taken to avoid sharp points when terminating the cable to prevent corona
discharges.
The interconnect cable supplied with the antenna tuner should be routed away
from other cables back to the Transceiver and connected as indicated in the
diagram overleaf.
Ground (Earth) System
The ground (earth) system is a key part of the overall antenna system and consequently the system operation. An inadequate ground system is the primary
cause of poor performance and tuning problems. There is little point in installing the antenna unless a good ground system can be provided.
Metal hulled vessels provide an almost perfect ground. The tuner ground
terminal should be connected directly to the hull using the shortest possible
ground strap. The point of connection to the hull should be prepared so that it
is free of paint and rust to ensure a good contact area with minimum electrical
resistance.

copper sheet with an area of not less than 4 square metres should be moulded
into the hull during lamination. A suitable heavy strap should be connected to
the sheet and left free for earth connection.
Should neither of these methods be available it will be necessary to bond as
many large metallic objects, such as the engine and propeller shaft, together to
form a ground.
Whichever method is used the ground run from the ground system to the
antenna tuner should be as short as possible and use copper strap at least
50 mm wide (wider if available). Consideration must always be given to the
problem of electrolysis. Severe structural damage may occur if electrolysis is
present.
Corrosion
All connections in marine situations are subject to corrosion and oxidation.
To minimise this all joints should be cleaned and have silicon grease applied
before assembly. Under severe conditions joints should be protected with self
vulcanising rubber tape.
Electrical Checkout
After mechanical installation is complete, select the highest frequency to be
used on the Transceiver. A directional watt-meter such as a Bird Model 43
should be inserted in the coaxial transmission line between the Transceiver
and the tuner. The tune mode on the Transceiver is then energised (refer to the
Transceiver user manual). Upon application of RF energy, the tuner should start
to tune, indicated by the âclatteringâ of the tuner relays. After a few seconds
the relay noise will cease. The Transceiver should indicate a successful tune and
WKHZDWWPHWHUUHĂHFWHGSRZHUVKRXOGLQGLFDWHDORZYDOXHFRQVLVWHQWZLWKD
VSWR of better than 2:1. If the cover of the tuner is removed, the PCB mounted
âtunedâ LED should be illuminated. Now select the lowest desired frequency on
the Transceiver and repeat the above procedure. The result should be the same,
except that the tune cycle may take longer. If the above procedure does not
give the results as indicated, check that the antenna length and connections
are correct and re-check all ground (earth) connections.

BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Note: When received, the Barrett 911 automatic antenna tuner memory system will
usually not have any pre-stored tuning information appropriate to your installation.
To allow the 911 to âlearnâ its tuning information simply proceed from one channel
to the next allowing the normal tune cycle to take place. Each successful tune is
âmemorisedâ so that when that channel is re-selected, the tuner will almost instantaneously retune to that frequency.

Overview of HF Operation
HF (High Frequency) is the radio spectrum with frequencies between 1.6 and
0+]:LWKLQWKLVUDGLRVSHFWUXPDQHIĂFLHQWIRUPRIWUDQVPLWWHUPRGXODtion, SSB (Single Side Band), is used. This, combined with the use of the ionosphere - a layer of ionisation gases that resides between 100 and 700 km above
WKHHDUWK¡VVXUIDFHSURYLGHVHIĂFLHQWFRVWHIIHFWLYHFRPPXQLFDWLRQVRYHU
short, medium and long distances - without the need for expensive re-transmission devices, such as the VHF or UHF repeaters or satellites, all of which have
ongoing operational costs and a reliance on a physical infrastructure.
In many remote areas, HF / SSB is the only form of communication possible.
HF Propagation
When HF / SSB radio waves are generated by the Transceiver there are usually
two components:
â˘
The ground-wave, which travels directly from the transmitting antenna to
the receiving antenna following the contours of the earth.
â˘
The sky-wave, which travels upward and at an angle from the antenna,
until it reaches the ionosphere (an ionised layer high above the earthâs
surface), and is then refracted back down to earth, to the receiving
antenna.
Generally speaking, ground-wave is used to communicate over shorter distances usually less than 50 km. Because ground-wave follows the contours of
the earth, it is affected by the type of terrain it passes over. Ground wave is
rapidly reduced in level when it passes over heavily forested areas or mountainous terrain.
Sky-wave is used to communicate reliably over medium to long distances up to
3,000 km. Whilst the nature of sky-wave propagation means it is not affected
by the type of terrain as in ground-waves, it is affected by factors involving the
ionosphere as described below.
203
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Radio Wave Propagation
The following illustrations show the characteristics of ground-wave and skywave 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. The diagrams illustrate that the
ground-wave is not affected by the time of day and the height of the ionosphere above the ground.

Factors Which Affect HF / SSB Communications
There are a number of different factors which will affect the success of communications via HF / SSB radio. These are outlined below:
Frequency Selection
Frequency selection is perhaps the most important factor that will determine
the success of your HF / SSB communications.
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 Transceiver,
PDNHVĂQGLQJWKHFRUUHFWIUHTXHQF\WRXVHHDV\$%HDFRQ&DOOLVEDVHGRQWKH
Network Transceivers all having a selection of frequencies that will accommodate most ionospheric conditions. When in standby, the network Transceivers
scan these frequencies waiting for a call (Selcall or Beacon Call) from another
Transceiver. The Transceiver wishing to check for the best frequency to operate
on sends a Beacon Call to the station to be contacted. If the call to the other
station is successful, a revertive tone from the station being called will be
heard, indicating the channel selected was suitable for the ionospheric conditions prevailing. If the revertive tone is not heard or is very weak, another channel may be tried until a revertive tone of satisfactory signal strength is heard.
(Refer to Beacon Calls on page 32 for more details.)
Time of Day
As a rule, the higher the sun, the higher the frequency that should be used.
This means that you will generally use a low frequency to communicate early
morning, late afternoon and evening, but you will use a higher frequency
to cover the same distance during times when the sun is high in the sky (for
example, midday). You will need to observe the above rule carefully if your
Transceiver has a limited number of frequencies programmed into it, as you
may only be able to communicate effectively at certain times of the day.
Weather Conditions
Certain weather conditions will also affect HF / SSB communications. Stormy
conditions will increase the background noise as a result of static caused by
lightning. This background noise could rise to a level that will blank out the
signals you are trying to receive.
205
BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
Man-made Electrical Interference
Interference of an electrical nature can be caused by overhanging power lines,
high power generators, air-conditioners, thermostats, refrigerators and vehicle
engines, when in close proximity to your antenna. The result of such interference may cause a continuous or intermittent increase in the level of background noise.

the success of your HF / SSB communications. Your choice of antenna system
and power supply is critical. Correct installation is also extremely important. An
HF / SSB Transceiver is generally installed using different rules to those used to
install VHF or UHF Transceivers. Failure to correctly install an HF / SSB system
will greatly affect the communications quality you will obtain.
