This facility (when pro-grammed) 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 example, the microphone becomes jammed between seats in a vehicle causing the PTT (transmit) switch to be held down.

Each channel requires the following parameters to be set:• Channel Number• Channel Label• Rx Frequency• Tx Frequency• Channel Mode (USB, LSB, FSK, CW or AM)• Channel Power (10, 30, 125 or 150 watt) (Note: 150 W not available in Australia)• Selcall Format (RFDS Alarm, OEM, CCIR, International or None)• ALE Channel• Antenna Select (Main or Auxiliary)For information regarding adding a new channel, see page 61.$

26BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALEmergency CallsAll Selcall emergency calls are transmitted by pressing the and buttons together for more than two seconds. The emergency call sequence commences when the buttons are released. The action of the emergency call depends on how the Transceiver has been pro-grammed. For example:• Selective Call alarm that only transmits on the currently selected channel Transmits the emergency Selcall sequence once on each press of the and buttons. • Selective Call alarm that transmits and automatically changes to a selec-tion of channels Transmits the emergency Selcall sequence twice on each channel pro-grammed as an emergency channel.• Royal Flying Doctor Service (RFDS) alarm Two-tone alarm 880 Hz + 1320 Hz continuous (Australian use only) – alerts the Royal Flying Doctor Service on RFDS channels. The RFDS alarm will continue transmitting for ten seconds even if you have released the and buttons. To cancel the RFDS alarm, press the PTT button or the button. Note: A momentary press of the and buttons initiates an RFDS alarm test mode which emits the audio tones but does not transmit them. Another momentary press of the and buttons or PTT cancels the RFDS alarm test mode. ,ID*36UHFHLYHULVÀWWHGDQGHQDEOHGWKH*36SRVLWLRQLVDOVRVHQWZLWKWKHcall.

$29BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALSelective Call - SelcallSelcall (selective calling) is a digital signalling system based on the standard CCIR-493 for use on HF networks. It is a type of squelch protocol used in radio communications systems, in which transmissions include a brief burst of sequential audio tones. Receivers that are set to respond to the transmitted tone sequence will open their squelch, while others will remain muted.Selcall Self IDsEach station in an HF network can be assigned up to 14 different Self IDs of ZKLFKWKHUHFDQEHDPL[WXUHRIIRXURUVL[GLJLW,'VLGHQWLÀFDWLRQ$VWDWLRQcan be called using any of these Self IDs.Selcall DecodeThe 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 Transmit6HOFDOOIRUPDWVLQWUDQVPLWDUHFKDQQHOVSHFLÀF)RUH[DPSOHRQO\FDOOW\SHVprogrammed for the channel are permitted.

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 RangesThe standard Selcall system accommodates four and six digit networks.

$32BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALBeacon CallA 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 alert-ing 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 subse-quent Selcalls or Telcalls.Note: both stations must be programmed for Selcall or Telcall operation.

Tap the appropriate digits for the search, then tap Enter.

132BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALHopThis 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 BandSelect 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 CodeFor 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 BandwidthsSecurity codes 00000000 to 19999999 are used for hopping ± 2 kHzSecurity codes 20000000 to 49999999 are used for hopping ± 16 kHzSecurity codes 50000000 to 99999999 are used for hopping ± 128 kHzHopping up to ± 2 kHz is useful for narrow band antennas such as when using antenna tuners in manpack operation.Hopping up to ± 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 viewed.

NR OffNR LowNR Medium NR HighScanScanning 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:• Signal Strength Level (SSL) mute is selected and a signal with a level greater than the pre-set threshold is received.• Audio (syllabic) mute is selected and a voice signal is detected.

136BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALTap 6FDQ from the Home screen to initiate scanning the channels.Whilst scanning The Rx icon changes colour from green to orange, several options on the screen are hidden (Menu, Channels, Hop, Tune, and Mode), the Scan icon is animated, and the keypad’s directional keys are disabled.To stop scanning, press .See page 72 for setting the attri-butes for scanning.Selcall ScanWhen a Selcall signal is detected, and the channel has Selcall enabled, no mat-ter 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) ScanIf 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.

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 fre-quency (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 unsuita-ble 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 ÀQDOLVHGWRDYRLGV\VWHPSHUIRUPDQFHGLVDSSRLQWPHQWThe following should be considered when choosing a position for the Trans-ceiver:Operating ConvenienceThe Transceiver should be placed so that the operator is com-fortable and any required facilities are easily accessible.

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 pre-sented 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.

Voltage Drop The average current consumption of the Transceiver is low but during transmis-sion 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.

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 ¼ wavelength. Radiation is at a minimum at the end points of the antenna. Inverted “V” 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 acci-dental contact.Transceiver and Tuner MountingThe 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.

$174BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALGround (Earth) SystemThe ground (earth) system is a key part of the overall antenna system and con-sequently the system operation. An inadequate ground system is the primary cause of poor performance and tuning problems. There is little point in install-ing 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:• The water pipe is close to the tuner and the water pipe enters the groundclose to the tuner.• There are no joints or couplings in the pipe that will increase the resist-ance path to ground.• The water pipe enters soil with good conductivity.• A low resistance joint is made with the water pipe.)UHTXHQWO\WKHJURXQGFRQGXFWLYLW\ZLOOQRWEHVXIÀFLHQWWRSURYLGHDVDWLVIDF-tory ground for the Barrett 911 tuner.

This will also be the case in rooftop installations where no H[LVWLQJJURXQGSODWHVXFKDVPHWDOURRÀQJH[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.$

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 ade-quate. The tune mode on the Transceiver is then energised. Upon application of RF energy, the tuner should start to tune, indicated by the ‘clattering’ 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 indica-WLRQRIWKHVKRXOGVKRZDORZYDOXHUHÁHFWHGSRZHUFRQVLVWHQWZLWKDVSWR of better than 2:1. Now select the lowest desired frequency on the Trans-ceiver 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 ‘learn’ its tuning information, simply proceed from one channel to the next allowing the normal tune cycle to take place.

180BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALMobile InstallationsSite Selection RecommendationsThe 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 recom-mended and “under dash” 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 Trans-ceiver may be mounted under a seat, in the luggage com-partment or any other out of the way place within the vehicle ZKLFKDOORZVIRUVXIÀFLHQWFRROLQJAll equipment should be positioned in such a way that conve-nient 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 equip-ment 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 mount-ing may need reinforcement.3UHFDXWLRQVVKRXOGEHWDNHQWRHQVXUHÀ[LQJVFUHZVHWFFDQQRWvibrate loose.

$182BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALAntennaIn any radio system an effective antenna installation is essential. Because of the QHHGWRUHGXFHWKHVL]HRI+)DQWHQQDVVRWKDWWKH\FDQEHÀWWHGWRDYHKLFOH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 satisfac-tory 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 UHPRYHGIURPWKHUHVSHFWLYHÀ[LQJSRLQWV7KHPRXQWLQJSRLQWPXVWSURYLGHD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.$

$183BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALNoise 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.

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 “all off” 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:$

$184BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALIgnition 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.

Separate the wire from all other wiring, keep it as short as possible and, if longer than about 300 mm it should be shielded as described above.Other Regulator WiresThese are normally adequately suppressed using good low-inductance bypass capacitors. To be effective, these ca-pacitors must connect to the wires to be suppressed and to chassis with very short leads. For this reason, the ‘pigtail’ style of suppressor capacitor often used with MF broadcast receivers is generally ineffective at HF.Electric Motors (windscreen wip-ers, fans etc.)Small electric motors can usually be suppressed with good low inductance bypass capacitors.$

$185BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALEngine Instru-mentationCertain types of oil-pressure sensors and voltage regulators used in instrument systems contain a vibrating or thermal cycling contact. These devices can only be suppressed by isolating and screening or wiring in the same way as described for the alternator to regulator control wire. Disc ceramic capacitors with short leads (protected with insulat-ing sleeving) are frequently useful but to prevent damage to instrument contacts, where the use of bypass capacitors is attempted, values larger than 1 nF should not be used.General Noise Suppression TipsWhen searching for sources of noise, some of their characteristics can be help-IXOLQLGHQWLÀFDWLRQ• Petrol engine ignition noise and contact breaker noise is a sharp staccato ‘plop’ varying with engine speed. It is only with this class of noise that the impulse noise limiter incorporated within some Transceivers is effective.• Noise from other sources generally has a more ‘mushy’ sound. That from the alternator / generator may only be troublesome over a limited range RIHQJLQHVSHHGDQGFDQDOVREHLQÁXHQFHGE\WKHVWDWHRIFKDUJHRIWKHbattery.• The noise from instrument regulators may depend on the battery voltage, the reading of the instrument and the length of time the system has been switched on. For this reason, the search for noise sources must be done thoroughly to prevent noise from apparently reappearing after the instal-lation has been completed.• Electric motors generate a ‘whining’ sound. Do not forget to check wind-screen wipers, electric fuel pumps, heater and air conditioning fans and other motors which operate only on an intermittent basis.$

193BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL914 Series Manual Tap Whip Antenna(Barrett P/N BC91401 to BC91424) Installation914 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). 'RQRWXVH3/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. Gener-ally 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).

$194BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALFor 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 “tuning rings”. 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 LQGLFDWHVWKDWWKHUHLVLQVXIÀFLHQW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 highest frequency on the whip requires adjustment, initially place the tuning ring here and slowly move upwards until a satisfactory SWR is obtained.,IWKHIDFWRU\WXQLQJULQJLVQRWÀWWHG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.If the VSWR gets worse when fol-lowing 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 mount-ing close to bodywork as in cab-over type vehicles. In this case, either re-site the antenna further away or add extra tuning rings to the frequency sections affected until a suitable VSWR 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.$

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 XVHG7KHDQWHQQDHIÀFLHQF\ZLOOEHSURSRUWLRQDOWRWKHOHQJWKRIWKHDQWHQQDand will be maximum when the length of the antenna approaches ¼ wave-length. It is advisable to limit the wire antenna to ¼ or ¾ wavelength at the highest frequency to be used.$

199BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALAntenna 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 VROLGÀ[LQJSRLQWXVLQJWKHPRXQWLQJFUDGOH0DNHVXUHWKHUHLVVXIÀFLHQWVSDFH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 con-sequently the system operation. An inadequate ground system is the primary cause of poor performance and tuning problems. There is little point in install-ing 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.

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 CheckoutAfter 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 ‘clattering’ of the tuner relays. After a few seconds the relay noise will cease. The Transceiver should indicate a successful tune and WKHZDWWPHWHUUHÁHFWHGSRZHUVKRXOGLQGLFDWHDORZYDOXHFRQVLVWHQWZLWKDVSWR of better than 2:1. If the cover of the tuner is removed, the PCB mounted ‘tuned’ 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.$

201BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALNote: 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 ‘learn’ its tuning information simply proceed from one channel to the next allowing the normal tune cycle to take place. Each successful tune is ‘memorised’ so that when that channel is re-selected, the tuner will almost instanta-neously retune to that frequency.Connection Details For a 4050 Transceiver and 911 Automatic Antenna Tuner in a Marine Installation+_+12 V DC16451077892311

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 mountain-ous 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.$

$205BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALFactors Which Affect HF / SSB CommunicationsThere are a number of different factors which will affect the success of commu-nications via HF / SSB radio. These are outlined below:Frequency SelectionFrequency selection is perhaps the most important factor that will determine the success of your HF / SSB communications.Generally speaking the greater the distance over which you want to communi-cate, the higher the frequency you should use.Beacon Call, a Selcall (Selective Call) function built into the Barrett Transceiver, PDNHVÀQGLQJWKHFRUUHFWIUHTXHQF\WRXVHHDV\$%HDFRQ&DOOLVEDVHGRQWKHNetwork Transceivers all having a selection of frequencies that will accommo-date 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 condi-tions prevailing. If the revertive tone is not heard or is very weak, another chan-nel 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 DayAs 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 ConditionsCertain 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.$

$206BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUALMan-made Electrical InterferenceInterference of an electrical nature can be caused by overhanging power lines, high power generators, air-conditioners, thermostats, refrigerators and vehicle engines, when in close proximity to your antenna. The result of such inter-ference may cause a continuous or intermittent increase in the level of back-ground noise.6\VWHP&RQÀJXUDWLRQDQG,QVWDOODWLRQ7KHPHWKRGLQZKLFK\RXUV\VWHPLVFRQÀJXUHGDQGLQVWDOOHGZLOODOVRDIIHFWthe success of your HF / SSB communications. Your choice of antenna system and power supply is critical. Correct installation is also extremely important. An HF / SSB Transceiver is generally installed using different rules to those used to install VHF or UHF Transceivers. Failure to correctly install an HF / SSB system will greatly affect the communications quality you will obtain. <RXUORFDO%DUUHWWUHSUHVHQWDWLYHZLOOEHDEOHWRDVVLVWZLWK\RXUV\VWHPFRQÀJX-ration and / or installation.HF Communications Compared with VHF or UHF Short Distance CommunicationsCommunications on any HF / SSB Transceiver will sound different to that on a VHF (Very High Frequency) radio or UHF (Ultra High Frequency) radio or telephone. This is because of the nature of HF propagation and the modulation methods used. On HF / SSB Transceivers there will always be background noise evident behind the signal you are receiving and this will increase when there is electrical interference or thunderstorm activity in the area.$
