1 General information
1.1 IntroductionThe 150W / 250W MF/HF transceiver with integrated DSC and telex is designed for maritime applicationsin voluntary as well as compulsorily fitted vessels. It offers simplex and semi-duplex SSB radiotelephonecommunication in the maritime mobile frequency bands between 1.6 and 30 MHz. The basic version ofthe transceiver include voice, DSC and a dedicated 2187,5kHz DSC watch receiver, forming an idealsystem for MF GMDSS installations. The transceiver can easily be upgraded to include 6 channelscanning DSC watch receiver, and Telex operation to comply with MF/HF requirements in sea area A3.The upgrade is done by entering software license codes.The equipment consists of a compact transceiver control unit, a fully remote controlled transceiver unitand an automatic antenna tuning unit.The microprocessor controlled Antenna Tuning Unit automatically matches the impedance of antennasbetween 8 and 18 metres in length and requires no presetting at the installation. The typical tuning timeis 1 s. It is designed for outdoor installation and may be located up to 100 metres from the TransceiverUnit.The Transceiver Unit contains all receiver and transmitter circuits. The fully protected solid state 150W/ 250W power amplifier cooled by natural convection matches a 50 ohm antenna system, but is normallyused in connection with the Antenna Tuning Unit. The DSC/Telex modem contains two demodulators,one connected to the built-in watch receiver for continuous watch on the DSC distress frequency 2187.5kHz, the other connected to the communication receiver which may be used to keep simultaneous watchon other DSC frequencies or may be used for telex communication.The Control Unit is for operation of radiotelephone as well as DSC and telex functions. Use of theequipment is simple, logic and straight forward. DSC operation is based on the use of soft keys. Guidingtexts are provided and the large display is able to show the contents of a complete call in one screen.For telex operation the keyboard, printer or data terminal can be connected directly to the control unit.The equipment is designed for operation from a 24 V battery. With the optional AC Power Supply unitinstalled the equipment may be supplied from 115/230 V AC main or emergency supplies with automaticswitch-over to 24 V DC supply in the absence of AC supply voltage.

2.3 Ground connections
Antenna Tuning UnitAs the earth connection of a transmitter is a very importantpart of the antenna system, it is of the utmost importanceto keep in mind that the earth connection of the AntennaTuning Unit must have the lowest possible RF-impedance.Losses in the earth connection will result in a decrease inradiated power which means that the range of thetransmitter will be reduced. In steel ships a 100 x 0.5 mmcopper strap as short as possible is connected betweenthe earth terminal at the bottom of the Antenna TuningUnit and two or three 1/2" or M12 bolts welded to thesuperstructure. Vessels constructed of non-conductingmaterials must be equipped with a copper earth platehaving a minimum area of 1 square metre mounted belowthe water line. From a copper earth bolt hard soldered tothe earth plate a 100 x 0.5 mm copper strap is run,preferably uninterrupted to the earth terminal at the bottomof the Antenna Tuning Unit.Should it be necessary to break the copper strap, for example to pass through a deck, two or three 1/2"or M12 bolts should be used for this feed through. On wooden ships having a superstructure of metal,this superstructure should also be effectively connected to the copper strap by using stainless steel boltsand preferably pieces of stainless steel strips between the metal parts. On fibre glass boats, such asyachts and sailing boats, it may be difficult to install a sufficiently good earth. Short copper straps arebolted to conducting parts on the engine, the keel and other conducting objects. Many copper straps canbe glued to the inner surface of the hull below the water line to produce a large capacitance to the water.It is important that the total area of copper is large and that the distance between the copper surface andthe water is as small as possible. The copper straps are connected directly to the ATU.
Transceiver Unit and Control UnitThe Transceiver Unit is preferably groundedseparately to the ships metal in the shortest possibleway. A 10 to 16mm sq. ground wire is connected tothe ground terminal (cable clamp) at the bottom ofthe unit.
2.4 Grounding considerationsProper system grounding is one of the most important installation details.Two areas of grounding must be considered:
a) The ground connection between the ATU and earth ground plane.b) The ground connection of the TU and the externally connected equipment.
Each area requires separate considerationseven though they are interrelated. Ideally theControl Unit, Transceiver Unit, Antenna Tun-ing Unit and the antenna ground-plane musthave the same RF ground potential. Unfortu-nately this situation is seldom achieved, butinterference problems will be reduced alongwith how close to this “ideal” the grounding ofthe installation is performed.On some installations ground loops will causeproblems. A ground loop is caused by morethan one ground path for a given unit. This willintroduce circulating RF currents which maycause malfunction of other equipment onboardthe ship as well as a “hot” handset.

Antenna startThe vertical antenna always start at its electrical ground-plane, whether or not it is physically mountedthere. First determine the antenna’s electrical ground-plane, which is where the ATU must be mounted.Where possible always take the ATU to the ground, not the ground to the ATU.In case of a fibreglass boat, the ground-plane may well be at the hull grounding terminal. Then this is wherethe Antenna Tuning Unit should go and this is where the antenna actually starts.

2.5 Antennas
Transceiver AntennaThe equipment is used with common transmitting and receiving antenna. The antenna should be erectedin the open, away from conducting object such as derricks etc. which may cause reduction of the radiatedpower. Insulators should be of the best type having low leakage even when wet. Stays, wires, steel mastsetc. should be either effectively earthed or insulated. The antenna should also be kept as far away aspossible from electrical equipment in order to minimize noise. Electrical installation such as cable braiding(screens) and instruments in the vicinity of the antenna should be earthed effectively, and the instrumentsin question should be fitted with noise-interference suppression devices, effective in the range 0.1 MHzto 30 MHz to avoid malfunction of these instruments. The Antenna Tuning Unit will tune on any frequencyin the range 1.6 to 27 MHz to good whip and/or wire installations of 12 to 18 meters total electrical length.Shorter antennas, electrical length down to 8 meters can be used. Where possible long antennas shouldbe installed to maximize the radiated power in the lower frequency bands.
In general a 12 meter antenna installation can be made using an 8 meter whip and 4.5 meter feeder ora 10 meter whip and 2.5 meter feeder. In both cases the whip should be mounted on a pole allowing forthe feeder to be erected at an angle of no less than 60 degrees to create a vertical antenna system. Usinghorizontal feeders or feeders mounted at an angle below 45 degrees usually transform the antennaradiation resistance to a lower value reducing the radiated power. Furthermore, the total antenna systemshould be kept well away from conductive objects such as the mast. Usually a horizontal distance of morethan 4 meters will create good results.Note: If a whip antenna is used this should have an anti-corona ball as a top termination to preventcrackling noise in the receiver.
The antenna is terminated at the insulator at the top of theAntenna Tuning Unit. The insulator must be relieved frommechanical stress by using max. 1 metre flexible wirebetween the insulator and a support. To maximize theradiated power and avoid flash over keep distance to metalparts as long as possible. All wire junctions in the antennasystem must be made with cable lugs of correct sizeaccording to the wire gauge. This will prevent bad connec-tions due to corrosion. For further corrosion proofing greasemay be applied to the cable joints.

DSC watch receiver antennaThe DSC watch receiver antenna may be an active or a passive type.The antenna should be erected well in the clear and kept away as far as possible from electricalequipment in order to minimize noise. Electrical installation such as cable braiding and instruments in thevicinity of the antenna should be earthed effectively, and the instruments in question should be fitted withnoise-interference suppression devices, effective in the range 0.1 to 30 MHz. The antenna feed-in shouldbe coaxial cable.In case of a passive antenna the feed-in should be as short as possible, especially in the case of shortantennas. The recommended antenna length is 7-30 meters. If a long coax cable is necessary animpedance matching transformer should be inserted at the antenna or an active antenna should be used.DC supply voltage for an active antenna is available at the DSC RX antenna connector. The supplyvoltage is +12 V for supply currents up to 20 mA. The short circuit current is limited to 2 mA to allow passiveantennas with matching transformers to be connected directly.

2.17 Final installation checkFor operation of the equipment please refer to the User Manual.
Check the hardware configuration of the transceiver by selecting FUNC and the ‘INFO & TEST’,‘INFORMATION’ ‘HW VERSION’ menu items, in particular check that the Antenna Tuning Unit isrecognized, if installed.
Perform a Self Test of the transceiver by selecting FUNC and the ‘INFO & TEST’, ‘CHECK’, ‘SELFTEST’menu items. The self test is performed automatically and is used for verification of all functions. Checkthe transmitter in all marine bands.
The Antenna Tuning Unit will tune automatically to the antenna first time the equipment is keyed on anew frequency or when the TUNE button is pressed. During the tune sequence and normal transmissionall transmitter circuits are monitored to ensure safe operating conditions. If transmission conditions arebad ( bad antenna installation, high temperatures, etc. ) the transmitted power will be reduced to a safelimit. If the transmission condition is improved automatic recovery to full power takes place.
The protection can be investigated by selecting FUNC and the ‘INFO & TEST’, ‘CHECK’, ‘TX PROTEC-TION’ menu items. The displayed protection code(s) is described in the Service chapter of this manual.If a GPS is connected, check position and time in the DSC Status display.If time is not contained in the NMEA sentences the time of position is indicated as —:—. In this case checkif the GPS output setting can be changed to allow time information. Otherwise UTC time must be enteredmanually each time the transceiver is switched on.
Send a DSC test call to the appropriate coast station. The acknowledgement from the coast station isreceived by the 2187.5 kHz watch receiver if the call was sent on that frequency. If the call is sent on HFonly the audio signal output from the 2187.5 kHz watch receiver should be checked by selecting FUNCand the ‘INFO & TEST’, ‘MONITOR’, ‘WR AUDIO’ menu items.

3 Technical description
3.1 Control UnitThe Control Unit consists of a main module 60-122876 and a MMI module 60-122877.
The main module consists of the digital part, i.e. the microprocessor, program FLASH PROM,configuration FLASH PROM, RAM, ScanBus data communication driver, SPARC-Bus driver, Printerinterface, Keyboard interface and data terminal interface.The main module also consists of an analog part, i.e. the voltage regulators, the analog interface circuitsand the analog output drivers (audio and light). The main module supports a build-in speaker and theconnectivity of an external 8 ohm speaker.
The MMI module contains the graphical TFT color display (240x320 dots), the display controller, keyboardinterface and encoders for volume and rotary knob.
3.2 Transceiver UnitBlock diagram page 3-3, Interconnection diagram page 3-4.
The Transceiver Unit consists of five modules. Three modules located in the base part of the unit: a controland interconnection module, a receiver/exciter signal path module, and a synthesizer and DSC RXmodule including master oscillator, and two modules are located in the door part of the unit: a poweramplifier module including filter bank and a switched mode power supply. The main wiring is by ribboncables with Micro MaTch connectors. RF signals are routed in coaxial cables using Taico, MCX and BNCconnectors.
3.3 Control/Intercon module 60-122878The Control/Intercon module performs the digital and analogue control of the transceiver functionsrequested by the Control Unit and contains interconnection circuits. The central part is the CPU. Theprogram software is contained in Flash PROM. A separate Flash PROM holds the configurationparameters. The processor communicates with the CU via the CAN interface, with auxiliary equipmentvia an RS-232 interface and the ATU via a modem circuit. Internal communication is via the TU Bus. Thetransmitter is monitored via the PA Peak, Filter Peak and Filter Average detectors. An adjustable opto-isolated battery detector circuit monitors the battery voltage at the Supply Alarm connector and triggersan alarm when outside the set range. The CPU also performs DSC modulator and dual DSC demodulatorfunctions. The modulator output is through a transversal filter. Audio switching allows loop back test.Audio circuits convert between unbalanced and balanced lines used by the ScanBus.
3.4 Synth. and DSC WR module 60-122879The Synthesiser part includes Master oscillator, dividers, 3.LO PLL and VCO, 2.LO filters and multiplierand 1.LO fractional N system as well as both 1. and 2. DSC LO PLL and VCO. The Master oscillatorgenerates a 17.8176MHz reference signal which is distributed to the local Synthesizer LO sub-circuits.The appropriate frequencies for the MF/HF transceiver are then generated.
The DSC Watch receiver is built up as a Double Super Heterodyne Receiver using Intermediatefrequencies of 30.155 MHz and 455 KHz.After frequency conversion to 455 KHz the signal is fed to 455 KHz IF2 AGC amplifier before led to finaldetection / conversion to 1700 Hz.The Signal is filtered out by 1700 Hz Audio filter and afterwards led to limiting amplifier thus creating theDSC output for further processing.The Receiver Signal Path also includes antenna supply and receiver protection circuitry.A RF splitter divides the DSC antenna signal between the Watch Receiver and the Main Receiver, whichuses the signal in telex mode.
The Synthesizer used for the Watch Receiver consists of the following sub circuits:

· An integer type PLL is used for creating the DSC LO1 signal. The PLL resolution is 2 KHz and afterdivision by 4 the final DSC LO1 resolution is 500 Hz. Three separate VCO´ s are used for coveringthe necessary frequency range. A 14.85 MHz TCXO is used for reference for the PLL.
· A doubler Circuit submitted to the 14,85 MHz reference signal is used for DSC LO2 signal thuscreating 29.70 MHz.
· A 14.6144 MHz TCXO divided by 32 thus creating 456.7 KHz is used for DSC LO3 signal.
3.5 RX/EX signal path module 60-122880The RX signal path includes protection, pre-selection, mixers, IF amplifiers, filter bank, demodulator,squelch and audio. The RX signal path has Automatic Gain Control. The RX signal path performs thehandling of the received antenna signal and delivers an AF signal, via the Control/Intercon module wherethe AF signal is converted from an unbalanced to a balanced signal, to the Control Unit.
The RX signal path also includes a DSC receiver signal path, which uses the MF/HF signal path, until thelast down conversion. DSC part includes a mixer, base band filter and hard limiter. During DSC reception,the DSC part overrules the normal MF/HF reception.
The EX signal path includes AF compressor, modulator, filter bank, mixers and EX output amplifiers. TheEX signal path has Automatic Loop Control. The EX signal path generates the modulated RF signal,adjusted to correct level - ALC adjusted signal, to the Power Amplifier.
The RX / EX signal path is controlled by the Control/Intercon module and receives its injection signal fromthe Synth./DSC WR module.
3.6 PA and Filters module 60-122881The PA and Filters module includes PA drivers, PA-stage, protection circuits, bias circuits, key circuit andfive low-pass filters with relays and relay drivers. The PA and Filters receives the modulated RF inputsignal from the RX/EX Signal Path and delivers the amplified and filtered output signal to the TX/RXconnector via a receive/transmit relay on the Control/Intercon module.
The low-pass filters removes the unwanted harmonic frequencies from the PA signal. The Filpeak andPAprotec outputs are monitoring signals for the Control/Intercon module. The driver and final poweramplifier stages are galvanically isolated on input and output as they are supplied directly from the 24 VDC input. The selection of low-pass filter is controlled by the Control/Intercon module.
The PA filters cover the frequency ranges:1.6 – 3.1 MHz3.1 – 5.0 MHz5.0 – 9.0 MHz9.0 – 17.0 MHz17.0 – 29.7 MHz
3.7 SMPS module 60-122882The Switched Mode Power Supply supplies the low power circuits of the equipment with the variousstabilized voltages required, and provides galvanic isolation from the supply source. The equipment issupplied from a 21.6 – 31.2 V DC power source. The module also carries the input filter and PA supplyoutput which is not galvanically isolated.
The power supply converts the incoming voltage to 7.5 V, +15 V, -15, and 25 V. The SMPS is switchedon from the Control Unit via the Scanbus SUPPLY ON wire and switched off under software control viathe SUPPLY ON/OFF connection from the Control/Intercon module. The DC supply voltage is sensed bya BAT INFO detector circuit and fed to the Control/Intercon module for automatic RF output poweradjustment.

3.10 Antenna Tuning Unit
ATU module 60-122883The ATU module comprises tuning network, measuring system and micro-controller circuits. The ATUmodule matches the impedance of the antenna to 50 ohm in order to gain the best possible SWR. TheATU module communicates tuning process and frequency information with the transceiver unit. Thetuning network consists of Capacitor Bank 1, Capacitor Bank 2, and an Inductor Bank. With these it ispossible to form either an L-network or a π-network. The capacitor banks and inductor bank are built upby binary related capacitors respectively binary related coils. The setting of capacitance and inductanceis accomplished by relays. A current detector at the antenna output terminal is used for measuring theantenna current for display at the Control Unit. To prevent overload of the relays, current detectors areincorporated in the Inductor Bank and in Capacitor Bank 2 and information fed back to the transceiverunit to decrease the output power if maximum permissible current is exceeded. To prevent overheatinga temperature sensor is incorporated which at excessive temperatures commands the transceiver toreduce the output power.
In receive mode an RX-Amplifier included in the Antenna Tuning Unit will be inserted, to improve thesensitivity of the system. It is possible to select the sensitivity in the steps OFF and NORMAL from theControl Unit.

3.12 Power control and protection systemThe Transceiver has an automatic power level system, which ensures that optimum power is deliveredto the Antenna. The Tune Sequence, which is automatically initiated when keying the transmitter aftera frequency change, makes the Tuning Network of the Antenna Tuning Unit tune to the best obtainableSWR. This is followed by an Automatic Level Control (ALC) adjustment according to the available powersupply voltage, measuring the output current of the PA Filters (FILPEAK @ 10 Vp at full output),transmitting AM carrier, and setting the overall gain by the ALC voltage (MGC/ALC). It is now possibleto transmit on full output power unless protection is activated or LOW POWER is selected. The outputpower is continuously monitored by the microprocessor, and is automatically adjusted during transmis-sion to provide reliable communication .
Power Amplifier ProtectionThe protection of the power amplifier consists of V+I protection, SWR protection, and thermal protection.When PA PEAK, the output signal of the voltage detector at the output of the power amplifier is exceeding10 V the output power is reduced to a safe level. If the ALC loop is at fault, disconnected or respondingtoo slow and the PA PEAK is exceeding 10V, the gain will be reduced in the power amplifier, operatingas a local and independent PA protection. The thermal protection consist of a temperature sensor on thepower amplifier and an average detector on the Control/Intercon module reducing the output power whenthe duty cycle of the transmitted signal exceeds 50% for more than 60 seconds. The available powersupply voltage is measured in the DC power supply and the information BAT INFO is transferred to theControl/Intercon module. If the supply voltage is dropping the microprocessor will adjust the output powerto keep distortion below the limits.
Antenna Tuning Unit ProtectionThe ATU is protected by several detectors all monitored by the ATU´s microprocessor, which calculatesthe SWR, temperature, maximum voltage and current. If these parameters are not below safe operatinglimits it requests for lower power.
Protection CodesThe current status of the power control and protection may be displayed in the form of Protection Codesby selecting MENU and the ‘INFO & TEST’, ‘CHECK’ and ‘TX PROTECTION’ menu items. The ProtectionCodes are described in the Service chapter of this manual.It should be noted that protection may be in force even under normal conditions e.g. code nos. 25, 44 and48:
No. 25 requests lower Pout relatively to increasing SWR at the Power amplifier.@ SWR= 1.1 reduction will only be a few watt’s@ SWR= 2.0 reduction will be 2-3 dB
No. 44 and 48 requests lower Pout relatively to increasing V or I at ATU.This is normal when transmitting on lower frequencies and short antennas (L<< 1/4 wavelength), and /or parallel capacitance present at the antenna, feeder, insulators, etc.

4 Service
4.1 Preventive maintenanceDue to the modern design of the transceiver preventive maintenance can be reduced to a minimumprovided the equipment is correctly installed. To ensure maximum performance and minimum repairtrouble we recommend you to follow the below stated headlines for preventive maintenance.
1. The condition of the battery should be checked at frequent intervals. The battery must always befully charged and should be topped up frequently with distilled water (liquid should be 5 to 10 mmabove the plates).
2. Check the condition of antenna installation, ground connection and cables at regular intervals.
3. Keep antenna feed-through insulators clean and dry.
4. Ensure that no objects are obstructing the free airflow through the cooling fins of the TransceiverUnit and keep the units free of dust accumulation to prevent overheating.
5. For cleaning use a damp cloth. Sticky dirt may be removed using a cloth with a weak soap solution.Wipe off with a clean cloth.
4.2 Realignment of master oscillatorThe master oscillator determines the exact transmit and receive frequencies of the equipment. Alloscillators age very slowly with time, typically with the highest drift rate the first year, approaching zerodrift after some years. Adjustment should be performed by a qualified technician with the necessary testequipment at his disposal.
1. Measuring Equipment:
Frequency Counter: Frequency range 100 MHzInput impedance = 1 MohmSensitivity at least 0.2 VrmsAccuracy better than 0.01ppm
2. Preparations:
2.1 Switch on the power at least 30 minutes before adjustment.2.2 Open the front of the Transceiver Unit.2.3 Locate X13 on SYNTH.AND DSC WR module 60-122879 carrying the 2. Local Oscillator
signal from the synthesizer to the RX/EX Signal Path. Connect the frequency counter probeto the inner conductor of the X13 socket on the synthesizer.
2.4 The ambient temperature should be within 10 to 30 deg. Celsius. Do not adjust the MasterOscillator shortly after long keying sequences of the transmitter. Be sure that thermalequilibrium has been reached before adjustment.
3. Realignment of Master Oscillator:
3.1 Locate the Master Oscillator adjustment hole in the metal cover over SYNTH.AND DSC WRmodule 60-122879. Use a small screwdriver to gently adjust the frequency.
3.2 Adjust the frequency as close as possible to 44.544 000 MHz.Adjustment tolerance +/-1Hz.
3.3 Remove the counter probe and refit the front of the Transceiver Unit.

4.6 Selftest
IntroductionThe ’SELF TEST’ BITE (Built-In Test Equipment) of the transceiver is used as a fault diagnosing tool forthe service technician. It may also be used by the operator to obtain additional information on a problemwhen ordering service.The ’SELF TEST’ checks the vital functions of the Transceivers modules by performing and monitoringa sequence of operations. The program controls the analog and digital set ups necessary to perform eachtest step in the line of tests executed during the ’SELF TEST’. These set ups will result in a digital feedback from go/no-go analog check detectors, A/D converters or digital circuits.
Self test descriptionThe ‘SELF TEST’ is started by selecting MENU and the ‘INFO &TEST’, ‘CHECK’, ‘SELFTEST’ menu items.All tests which does not involve transmission will automatically be performed successively until the lasttest has passed or an error condition has occurred. The test number and a name is displayed as the testproceeds.After the last test the user has the option to continue with a test of the transmitter with power deliveredto the antenna. The user selects the test frequency. Both receiver and transmitter are set to the testfrequency which should be selected so as to cause minimal disturbance of others.

If stopped due to an error condition, an error code is displayed. Only one error code is given as a resultof each test (the lowest number fitting). The user has the option to repeat the test or cancel.It is also possible to select a single test step for service purposes. Tests may be repeated several timesgiving a technician the opportunity to make measurements. Note that test on an arbitrary test number mayprovide a false indication to where the problem is, as the self test assumes that all previous test steps havebeen performed and found OK.
