Preface

Radio for occupational use

The SAILOR 6300B MF/HF DSC fulﬁ ls the requirements of the SOLAS directive and is intended for use in maritime

environment.

SAILOR 6300B MF/HF DSC is designed for occupational use only and must be operated by licensed personnel only.

SAILOR 6300B MF/HF DSC is not intended for use in an uncontrolled environment by general public.

Training information (for FCC approved equipment)

The SAILOR 6300B MF/HF DSC is designed for occupational use only and is also classiﬁ ed as such. It must be ope-

rated by licensed personnel only. It must only be used in the course of employment by individuals aware of both

the hazards as well as the way to minimize those hazards.

The radio is thus NOT intended for use in an uncontrolled environment by general public. The SAILOR 6300 MF/HF

DSC has been tested and complies with the FCC RF exposure limits for Occupational Use Only. The radio also com-

plies with the following guidelines and standards regarding RF energy and electromagnetic energy levels including

the recommended levels for human exposure:

• FCC OET Bulletin 65 Supplement C, evaluating compliance with FCC guidelines for human exposure to radio

frequency electromagnetic ﬁ elds.

• American National Standards Institute (C95.1) IEEE standard for safety levels with respect to human exposure

to radio frequency electromagnetic ﬁ elds, 3 kHz to 300 GHz

• American National Standards Institute (C95.3) IEEE recommended practice for the measurement of potentially

hazardous electromagnetic ﬁ elds - RF and microwaves.

Below the RF exposure hazards and instructions in safe operation of the radio within the FCC RF exposure limits

established for it are described.

Warning

Your Thrane & Thrane radio set generates electromagnetic RF (radio frequency) energy when it is transmitting. To

ensure that you and those around you are not exposed to excessive amounts of that energy (beyond FCC allowable

limits for occupational use) and thus to avoid health hazards from excessive exposure to RF energy, FCC OET bulletin

65 establishes an Maximum Permissible Exposure (MPE) radius of 6 ft. (1.8 m) for the maximum power of your radio

(150 W selected) with a whip antenna having a maximum gain of 3.0 dBi.

The safety distance from the antenna is stated to:

Antenna Safety distance

150W 6 ft. which are equal to 184 cm > 156 cm

250W 7 ft. which are equal to 215 cm > 201 cm

500W 10 ft. which are equal to 307 cm > 285 cm

98-144591-A

Installation

1. A whip antenna with a maximum gain of 3 dBi must be mounted at least 12.6 ft. (3.9m) above the highest deck

where people may be staying during radio transmissions. The distance is to be measured vertically from the

lowest point of the antenna. This provides the minimum separation distance which is in compliance with RF

exposure requirements and is based on the MPE radius of 6 ft. (1.8m) plus the 6.6 ft. (2.0 m) height of an adult.

2. On vessels that cannot fulﬁ l requirements in item 1, the antenna must be mounted so that its lowest point is

at least 6 ft. (1.8m) vertically above the heads of people on deck and all persons must be outside the 6 ft. (1.8

m) MPE radius during radio transmission.

• Always mount the antenna at least 6 ft (1.8 m) from possible human access.

• Never touch the antenna when transmitting

• Use only authorized T&T accessories.

3. If the antenna has to be placed in public areas or near people with no awareness of the radio transmission, the

antenna must be placed at a distance not less than 12 ft. (3.6 m) from possible human access.

Failure to observe any of these warnings may cause you or other people to exceed FCC RF exposure limits or create

other dangerous conditions.

General information

1.1 Introduction

The 150 W/250 W/500 W MF/HF transceiver with integrated DSC and telex (NBDP) is designed for mari-

time applications in voluntary as well as compulsorily ﬁ tted vessels. It offers simplex and semi-duplex

SSB radiotelephone communication in the maritime mobile frequency bands between 1.6 and 30 MHz.

The basic version of the transceiver includes voice, DSC and a dedicated 2187.5 KHz DSC watch receiver,

forming an ideal system for MF GMDSS installations.

The equipment consists of a compact transceiver control unit, a fully remote controlled transceiver unit

and an automatic antenna tuning unit.

The microprocessor controlled Antenna Tuning Unit automatically matches the impedance of antennas

between 8 and 18 metres in length and requires no presetting at the installation. It is designed for outdoor

installation and may be located up to 100 metres from the Transceiver Unit.

The Transceiver Unit contains all receiver and transmitter circuits. The fully protected solid state 150 W/

250 W /500 W power ampliﬁ er matches a 50 ohm antenna system, but is normally used 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 frequencies, the other connected to

the communication receiver which may be used to keep simultaneous watch on other DSC frequencies

or telex communication.

The transceiver can be upgraded to scan 6 DSC channels, and Telex operation to comply with MF/HF

requirements in sea area A4. Codes are purchased as accessories for the system.

The Control Unit is for operation of radiotelephony as well as DSC and conﬁ guration. Use of the equip-

ment is simple, logic and straight forward. DSC operation is based on the use of soft keys. Guiding texts

are provided and the large display is able to show the contents of a complete call in one screen.

For telex operation the Message Terminal must be connected to the system via the CAN bus.

The equipment is designed for operation from a 24 V DC supply, like e.g. a battery. With the optional AC

Power Supply unit installed the equipment may be supplied from 115/230 V AC main or emergency sup-

plies with automatic switch-over to 24 V DC supply in the absence of AC supply voltage. Also optionally, a

battery charger for AC is available in the product line.

The built-in test facilities and easy-to-replace module design of the equipment simpliﬁ es the service concept.

Dissipated heat: The dissipated heat in standby RX mode is typically 45 W depending on

attached ancillary equipment.

In transmit mode, use the consumption ﬁ gures for the appropriate mode,

multiplied by 0.66.

E.g. 0.66 x 175 W = 115.5 W dissipated heat for a 150 W system in SSB

speech mode.

For a ﬁ gure in kilocalories (kcal), multiply dissipation effect by on-time in

hous and then by 0.860.

For the 150W system, e.g. 115.5 W x 2 h + 45 W x 22 h (TX 2 hours + RX

22 hours a day) = 1221 Wh. 1221 Wh x 0.860 ~ 1050 kcal a day.

2.2.4 Recommended ATU installation

On a metal-hull vessel

Install the ATU on an ATU Mounting Kit. The kit is stainless steel which can be bolted or welded to ship's

hull to ensure good and solid connection in the radio system primary ground point.

The mounting kit will at the same time ensure straight and ﬂ at mounting for the ATU cabinet and provide

good airﬂ ow around the ATU for better heat dissipation.

On a wooden or ﬁ breglass hull vessel

Install the ATU on an ATU Mounting Kit. The kit is stainless steel which can be bolted to ship's hull

and then provide a ground plane connection to ensure good and solid connection in the radio system

primary ground point.

The ground plane should normally be provided in as wide surface as possible with shortest possible

connection to ships earth connection to the water surface.

Alternatively and in case of long ground connections the grounding should be arranged in a solid and

shielded cable connection where sufﬁ cient cable square material to provide the connection and the

shielding connected to ATU Mounting Kit and left open at earth connection side.

ATU Mounting Kit

An optional ATU Mounting Kit as shown below is available in two versions:

1. Comprises of mounting plate and ﬁ ttings for mast - part no. 737589

For mounting the ATU directly on a mast, where the Mounting Plate and ﬁ ttings for mast can form a

sufﬁ cient earth connection on a steel mast welded to the superstructure.

2. Comprises of the mounting plate only - part no. 737588

Grounding considerations

2.3 Ground connections

2.3.1 Grounding considerations

Proper 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 plane.

b) The ground connection of the TU and the externally connected equipment.

Each area requires separate considerations even though they are interrelated. Ideally the Control Unit,

Transceiver Unit, Antenna Tuning Unit and the antenna ground-plane must have the same RF ground

potential. Unfortunately this situation is seldomly achieved, but interference problems will be reduced

along with how close to this “ideal” the grounding of the installation is performed.

On some installations ground loops will cause problems. A ground loop is caused by more than one

ground path for a given unit. This will introduce circulating RF currents which may cause malfunction

of other equipment onboard the ship as well as a “hot” handset.

2.3.2 RF ground loop

It is not always possible or practical to mount the ATU using a very short strap to the actual ground-

plane. In such a case the coaxialcable may be connected between units with different ground potentials

causing RF loop-current to ﬂ ow.

2.3.3 Minimizing ground loops

By routing the coax cable very close together with the ATU ground strap (secure good RF coupling

between the two) all the way down to the ground-plane, there will be no RF ground loop left to generate

the interference.

2.3.4 Antenna start

The vertical antenna always starts at its electrical ground-plane, whether or not it is physically mounted

there. 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 ﬁ breglass boat, the ground-plane may well be at the hull grounding terminal. Then this is

where the Antenna Tuning Unit should go and this is where the antenna actually starts.

2.3.5 Antenna Tuning Unit

As the earth connection of a transmitter is a very im-

portant part of the antenna system, it is of the

utmost importance to keep in mind that the earth con-

nection of the Antenna Tuning Unit must

have the lowest possible RF-impedance. Losses in the

earth connection will result in a decrease in

radiated power which means that the range of the

transmitter will be reduced. In steel ships a 100 x

0.5 mm copper strap as short as possible is connected

between the earth terminal at the bottom

of the Antenna Tuning Unit and two or three 1/2" or

M12 bolts welded to the superstructure.

It is recommended to install the ATU by means of the

ATU mounting bracket shown in section 2.2.4 as this

stainless steel bracket can be welded into the super

structure and will provide the best possible none cor-

roding connection.

Vessels constructed of non-conducting materials must be equipped with a copper earth plate having a

minimum area of 1 square metre mounted below the water line. From a copper earth bolt hard soldered

to the earth plate a 100 x 0.5 mm copper strap is run, preferably uninterrupted to the earth terminal at

the bottom of 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 con-

nected to the copper strap by using stainless steel

bolts and preferably pieces of stainless steel strips

between the metal parts.

On ﬁ bre glass boats, such as yachts and sailing boats,

it may be difﬁ cult to install a sufﬁ ciently good earth.

Short copper straps are bolted to conducting parts

on the engine, the keel and other conducting objects.

Many copper straps can be 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 and

the water is as small as possible. The copper straps

are connected directly to the ATU.

On ships where the environmental conditions re-

quire shielded grounding downlead in order to avoid

radiation from same downlead, it is recommended

to use a shielded cable with a non-stranded wire

having adequate wire dimension to secure the proper

grounding. Cable shielding should be connected the

earth terminal at the bottom of the Antenna Tuning

Unit and left open at the earth connection side.

2.3.6 Transceiver Unit and Control Unit

The Transceiver Unit is preferably grounded

separately to the ships metal in the shortest

possible way. A 10mm² (AWG 7) to 16mm²

(AWG 5) ground wire is connected to the

ground terminal (cable clamp) at the bot-

tom of the unit.

2.4 Antennas

2.4.1 Transceiver Antenna

The equipment is used with separate transmitting and receiving antennas. The antennas should be

erected in the open, away from conducting object such as derricks etc. which may cause reduction of

the radiated power. Insulators should be of the best type having low leakage even when wet. Stays,

wires, steel masts etc. should be either effectively earthed or insulated. The antenna should also be kept

as far away as possible 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 instruments in question should be ﬁ tted with noise-interference suppression devices, effective

in the range 0.1 MHz to 30 MHz to avoid malfunction of these instruments. The Antenna Tuning Unit

will tune on any frequency in the range 1.6 to 27 MHz to good whip and/or wire installations of 12 to

18 m total electrical length.

Shorter antennas, electrical length down to 8 m can be used. Where possible long antennas should be

installed to maximize the radiated power in the lower frequency bands.

In general a 12 m antenna installation can be made using an 8 metres whip and 4.5 m feeder or a 10 m

whip and 2.5 m feeder. In both cases the whip should be mounted on a pole allowing for the feeder to be

erected at an angle of no less than 60 degrees

to create a vertical antenna system. Using

horizontal feeders or feeders mounted at an

angle below 45 degrees usually transform the

antenna radiation resistance to a lower value

reducing the radiated power. Furthermore,

the total antenna system should be kept well

away from conductive objects such as the

mast. Usually a horizontal distance of more

than 4 metres will create good results.

The antenna is terminated at the insulator at

the top of the Antenna Tuning Unit. The insula-

tor must be relieved from mechanical stress

by using max. 1 meter ﬂ exible wire between

the insulator and a support. To maximize the

radiated power and avoid ﬂ ash over keep

distance to metal parts as long as possible.

All wire junctions in the antenna system

must be made with cable lugs of correct size

according to the wire gauge. This will prevent

bad connections due to corrosion. For further

corrosion prooﬁ ng grease may be applied to

the cable joints.

2.4.2 Considerations on antenna length requirements

Antenna impedance

The length of the transmitting antenna used with MF/HF equipment in general and the MF/HF equip-

ment speciﬁ cally for purpose of this discussion is of utmost importance for the proper performance of

the equipment, i.e. the ability to tune properly to the antenna and the effective transmission range. In

terms of transmission range, more important than increasing the transmitter RF output power from say

150 W to 250 W is in fact the use of an adequate length antenna.

Comparatively, any practical length whip antenna remains by far too short for the wavelength for which

it is used, especially at the lower frequencies. For the frequency range 1.6 – 30 MHz deﬁ ning the com-

mercial MF/HF marine band, the wavelength spans the range 190 – 10 m approximately.

A proper ground plane for the transmitting antenna is essential in order for this to effectively radiate

power into the air. When applying RF energy to the whip antenna, the presence of the ground plane

creates capacitance between the whip antenna and the ground plane. This capacitance will vary with

frequency, hence, the impedance of the whip antenna as seen from the transmitter will vary with the

frequency range over which the transmitter is operated.

As an illustration of the impedance variation with frequency of a transmitting antenna refer to below

table listing the impedance as measured on a 6, 7 and 8 m whip antenna respectively with a 2 m feed line.

Antennas

Function of the Antenna Tuning Unit (ATU)

The MF/HF transmitter power ampliﬁ er (PA) provides a ﬁ xed output impedance of 50 ohms over its

operating frequency range to which the load (the antenna) should be matched (i.e. load should prefer-

ably be 50 ohms also) in order for the transmitter to deliver its full power output to the load. However,

with the varying impedance of an antenna, as described above such a condition may only be met at

one or - at best - a few speciﬁ c frequencies. On the remaining frequencies within the transmission band

the varying mismatch between the transmitter ﬁ xed output impedance and the different impedance of

the antenna at any given frequency will result in reduced RF power delivered to the antenna – in worst

case hardly any power at all - if the antenna was connected directly to the transmitter.

To overcome the frequency dependant mismatch between the transmitter output impedance and the

antenna (load) impedance, the ATU is put into the antenna circuit to provide variable compensation

counteracting the varying impedance of the antenna, the end result of which is the “transformation” of

this into a “ﬁ xed” app. 50ohms load, as “seen” by the transmitter.

The compensation is achieved mainly through the introduction of an induction in series with the antenna

circuit, the value of which will create a resonance circuit at the given frequency. Hence, depending on

the impedance of the antenna (i.e. the transmission frequency) a suitable combination of inductors from

a bank of inductors in the ATU, are selected through of a number of relays, the activation of which is

controlled by the ATU processor during the tuning process.

MF/HF ATU

For the impedance of e.g. an 8 metres transmitting antenna of 5-j800 ohms at 2 MHz, as stated by the

manufacturer, the ATU will easily tune to the impedance of this antenna system - in fact, the array of

coils in the ATU tuning circuitry allows tuning all the way down to the impedance of 4-j1060 ohms of

this antenna system at 1.6 MHz. A slightly shorter antenna system might be used at the possible sacriﬁ ce

of the ability to tune at the extreme low end of the frequency band below 2 MHz.

However the impedance of the antenna system is, inﬂ uenced by any nearby metallic objects such as

the vessel's superstructure and/or nearby metal poles/masts or stays/wires. Consequently, in order not

to alter the impedance of the antenna system which may eventually cause difﬁ culties for the ATU to

match the resulting impedance, the transmitting antenna should be kept at a distance of no less than

4 m from any such objects. Similarly goes for the feed wire connecting the ATU to the antenna which

should be kept at a minimum of 1 m from metallic objects.

It should be noted that even though the ATU will tune to the mentioned antenna system length, the ef-

fective radiated power (i.e. the efﬁ ciency of the antenna) in the low frequency end will suffer compared

to longer antenna systems of recommended electrical length 10-18 m.

2-15

Installation

Chapter 2: Installation

98-144591-A

Antenna system installation in practice

As noted on the impedance ﬁ gures in above table,

the measurements were made with the antenna

raised on a 2 m steel pipe over a ﬂ at steel roof

(ground plane) and a 2 m feed line. This implies

that the measured impedance is in fact that of the

actual antenna (electrical) length plus additional 2

m. The electrical length of the 8 m bracket mount

(side fed) Comrod transmitter antenna is 6.8 m

resulting in a total electrical length of the antenna

system of 8.8 m.

Electrical speciﬁ cations transmitting antennas

The connection to the transmitting antenna is by a

single ended wire - the feed line - connecting from

the ATU top connector. This feed line adds to the

electrical length of the antenna (when correctly

installed), thus in effect increasing the efﬁ ciency

of the antenna. The longer the feed line the better

the efﬁ ciency of the antenna system consisting of

transmitting antenna and the feed line.

For direct addition of feed line length to antenna

electrical length the feed line should be vertically

installed as an extension downwards of the transmit-

ting antenna. In practice, where the ATU must be

placed between the feed line and the ground plane

(steel deck), the direct vertical installation of the

feed wire may be difﬁ cult in terms of total height.

This may partly be accounted for by allowing the

feed wire installed at an angle of at least 45 degrees

towards the horizontal plane. Installing the feed wire

at lower angles will create capacitance to the ground

plane decreasing the efﬁ ciency of the antenna.

2.4.3 Receiver antenna

The 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 electrical equip-

ment in order to minimize noise. Electrical installation such as cable braiding and instruments in the

vicinity of the antenna should be earthed effectively, and the instruments in question should be ﬁ tted

with noise-interference suppression devices, effective in the range 0.1 to 30 MHz. The antenna feed-in

should be coaxial cable.

In case of a passive antenna the feed-in should be as short as possible, especially in the case of short

antennas. The recommended antenna length is 7-30 meters. If a long coax cable is necessary an im-

pedance 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 RX antenna connector after switching is on

in service interface. The supply voltage is +12 V (60 mA). The RX port is short circuit protected.

The receiver antenna should be mounted as far from the transmitter antenna as possible - recommended

minimum 6 metres.

For active RX antennas, it is recommended to choose a physical length ≥1 meter.

2.5 DC Power cabling

The supply leads are connected to the supply terminal of the Transceiver Unit. The supply terminal is

designed for 3 wire shielded power supply cable to meet international installation and EMC requirements.

The safety ground wire is connected to the terminal showing ground symbol and shielding connected

to the cable ﬁ tting shown in page 2-3 must be well grounded to ships hull.

The earth connection of the equipment will not cause the battery to be earthed. Maximum permissible

peak voltage between the battery terminals and earth is 100 V.

Fusing must be provided in the supply leads for cable protection.

Cable lengths stated in tables are the total cable length from battery terminals via charger, shunt box,

DC distribution to TU DC-terminals.

2.7 Position and time information

2.7.1 Connection of Navigation Equipment

Navigation equipment complying with the NMEA 0183/IEC 61162-1 standard may be connected for

automatic position and time updating. Connection is made to the NMEA+/NMEA- connections in the

Control Unit ACC connector or the NMEA+/NMEA- connections in the Transceiver Unit AUX connector.

The NMEA receive circuit consists of an optoisolator with a 470 ohms series resistor to insure current

mode operation and a shunt diode to limit reverse bias as shown below. The circuit is isolated from ground.

NMEA IN -

NMEA IN +

The circuit operates with a minimum

differential input voltage of 2 volts

and draws less than 2 mA from the

line at that voltage. The maximum

voltage is 15 volts.

Interconnection between devices may be by means of two-conductor shielded twisted-pair cable.

Multiple listeners may be connected to a single talker. The receivers are connected in parallel. The shield

should be connected to the navigator chassis and should not be connected at any listener. However the

shield should be continuous (unbroken) between all listeners.

Supported sentences:

GLL (longitude, lattitude, utc, status, mode)

GGA (longitide, lattitude, utc, quality )

RMC (longitude, lattitude, utc, status, mode)

GNS (longitude, lattitude, utc, mode)

ZDA (utc, day, month, year)

Only the mentioned ﬁ elds are used - the rest are discarded.

NMEA data on the LAN-connection is also accepted. This data should comply with IEC 61162-450.

3.10 Antenna Tuning Unit

3.10.1 ATU module 60-122883 (150 W/250 W)

The ATU module comprises of a tuning network, measuring system and micro-controller circuits. The ATU module

matches the impedance of the antenna to 50 ohm in order to gain the best possible SWR towards the TU. The TU

communicates tuning process and frequency information with the ATU. The tuning network consists of capacitor bank

1, capacitor bank 2, and an inductor bank. With these banks it is possible to form either an L-network or a pi-network.

The capacitor banks and inductor bank are built up by binary related capacitors and coils. The setting of capacitance

and inductance is accomplished by relays. To prevent overload of the relays, current detectors are incorporated in

the inductor bank and in capacitor bank 2 and information fed back to the transceiver unit to decrease the output

power if maximum permissible current is exceeded. To prevent overheating a temperature sensor is incorporated

which at excessive temperatures commands the transceiver to reduce the output power.

In receive mode an RX-Ampliﬁ er included in the Antenna Tuning Unit is utilized, to improve the sensitivity of the

system by providing 50 ohm impedance. This is only used when connected to a 6000A MF/HF System.
