Training information 
(for FCC approved equipment)
The SAILOR 6300 MF/HF DSC is designed for occupational use 
only and is also classified as such. It must be operated 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 complies 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 fields.
• American National Standards Institute (C95.1) IEEE standard 
for safety levels with respect to human exposure to radio 
frequency electromagnetic fields, 3 kHz to 300 GHz
• American National Standards Institute (C95.3) IEEE 
recommended practice for the measurement of potentially 
hazardous electromagnetic fields - 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 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 
SAILOR6301_UM.book  Page viii  Friday, June 12, 2015  2:37 PM

ix
Permissible Exposure (MPE) radius of 6 ft. (1.8m) for the 
maximum power of your radio (150 W selected) with a whip 
antenna having a maximum gain of 3.0 dBi. This means all 
persons must be at least 6 ft. (1.8m) away from the antenna 
when the radio is transmitting.
Installation
1. A whip antenna with a maximum power 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 fulfil 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 Cobham SATCOM 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.

Introduction
Introduction 1
SAILOR 6300 MF/HF DSC
The SAILOR 6300 MF/HF 
DSC is a modular and flexible 
MF/HF radio that can be 
customized to your specific 
needs for MF/HF 
communication on work 
boats, high seas fishing 
vessels and merchant vessels 
of all kinds. It offers simplex and semi-duplex SSB radiotelephony in the 
maritime mobile frequency bands from 150 kHz to 30 MHz. Services 
include voice transmissions, watch function, DSC operations (Distress calls, 
position info, Distress relay and more) and AM Broadcast reception.
The large display shows Rx and Tx frequencies and status, MMSI number, 
position information, system and channel properties, including indicators 
for transmission power and received signal strength. It is easy to read from 
almost all angles and the display light can be adapted to dark environments. 
Red text is shown on a black background providing good visibility in low 
light conditions while protecting night vision.
DSC operations are made using the four soft keys next to the display. The 
MF/HF radio can replay the last 240 s of received voice. This is a useful 
feature to minimize misunderstandings and to record audio when the radio 
is unattended. The SAILOR 6300 MF/HF DSC has an Ethernet interface to 
connect to other equipment for control, monitoring and printing.
The SAILOR 6300 MF/HF DSC is available as a basic MF DSC radio that can

Operation
Channel information always available in the display
For some functions and for the setup pages, 
the channel and radiotelephony information 
is moved to the bottom section of the 
display. You can change frequencies 
whenever the frequencies are displayed.
If PTT is pressed the radio transmits on the 
displayed frequency on which the radio is 
tuned into for communication. If a signal is 
received, it is received on the displayed 
frequency.
Engagement status
The radio is engaged when an active DSC-initiated communication is 
ongoing, or communication is active on non-DSC initiated MF/HF 
operation: 
• A new channel is selected
• PTT is pressed
• Voice signal is received (if squelch is enabled)
The engagement state is used to prohibit incoming DSC calls from taking 
over control of the transmitter channel, disrupting ongoing communication.
When the radio is engaged in communication not initiated by DSC, this is 
indicated with the symbol   in the display. Engagement will 
automatically time-out on inactivity, after an inactivity time specified in 
DSC setup on page 45.
To terminate the engagement immediately press the soft key QUIT.

By pressing the SQLCH soft key, the operator can activate a squelch 
function on the MF/HF system. 
For 63xxA the squelch is an on/off function that is not adjustable to the 
operator. The squelch uses tone detection to estimate if a wanted 
signal is present.
For 63xxB : When squelch is enabled, use the RF gain knob to adjust the 
desired level of muting the noise signal.
In most cases, enable squelch when no signal is heard, turn the RF gain 
knob until the audio is muted. When a signal of greater level occurs, the 
audio will be unmuted.
For impact of squelch on replay see Replay function on page 42.

Sessions in the MF/HF radio
What is a session?
A DSC session is defined as a collection of DSC calls (transmitted and/or 
received) that are related to the same event (e.g. a Distress event) or 
established call (e.g. an individual call request followed by an 
acknowledgement).
A session can be either active or on hold. The active session has control 
over the radio transmitter. A session can have a purpose. For example if the 
purpose is to establish a communication on a working channel. 
The non-DSC communication (voice) is considered as a session that can be 
active (engaged) or on hold (dis-engaged). See also Engagement status on 
page 17.
Display for a session
In the lower part of the display 
the type of session, the 
current state, MMSI number 
of the other party and lapsed 
time since the reception of a 
call request or an 
acknowledgment is shown.
The session state icons, in the 
example  and R, show the state of the session:
•ACTIVE — the session icon is inverted, the transmitter tuned into 
the communication channel (in the example  , a DSC Routine 
call).
•HOLD — normal view, parked session (in the example , MF/HF 
voice communication.
•  For more information on the session state icons see Session state 
icons on page 33 below.
Note If two identical polling or test calls are sent from the same MMSI 
and the operator wants to resend a confirmation to the second 
call received, it is necessary to put the session on hold and then 
activate it again.

Handling multiple calls — DSC and voice
The SAILOR 6300 MF/HF DSC can control multiple DSC sessions 
simultaneously including a voice communication session. All sessions keep 
track of their session state and the communication channel used. 
A call — or session — can be on hold (HOLD) 
or active (ACTIVE). If there are several calls 
ongoing, they are shown as tabs in the display 
with their state (active, on hold, requiring 
attention). The DSC sessions on hold can 
receive calls that are pertinent to the session, 
even when the session is not displayed.
To close a session, the session must be active, then press the soft key

In case there are simultaneous alarms, they are sorted according to their 
priorities, the most important ones are shown first. In some cases alarm or 
pop-up messages terminate automatically, then the display messages and 
audible alarms also disappear automatically.
Geographical area calls
When making a DSC area call, enter the 
position of the ship (x,y) and the radius 
of interest r. This information is 
transformed to a square with a corner 
point (a,b) and the length of its sides, a 
and b. Then the DSC message is 
transmitted. The illustration on this 
page shows the relation between the 
user input — the white circle — and the 
information transmitted —the grey 
square. The center point is the position 
of the ship measured in degrees and minutes, whereas the radius of interest 
is in nautical miles.
The corner point of the square (a2,b2) and the length of its sides is given in 
degrees. Note that these values are rounded to degrees, and due to the 
requirement that the square shall include the entire circle; this will result in a 
slightly larger area than defined by the user input.
Attention when close to the poles: If the latitude of the corner point ‘a’ is 
transformed to a value greater that 90° then it is set to 90° and the length 
b is reduced correspondingly. If the length a is greater than 90° then a 
is set to 90°.
Phone book
Use the phone book when making a DSC call. You can enter up to 50 
contacts. The phone book is always sorted alphabetically by contact names. 
To sort phone book contacts use the soft key FILTER. The contacts can be 
sorted in ALL, COAST, SHIP or GROUP.

Overview
In this chapter you find detailed information on:
•Contact for support
•Maintenance
•Diagnostics
•Warranty and returning units for repair
Contact for support
Contact your authorized dealer for technical service and support of the 
MF/HF radio. Before contacting your authorized dealer you can go through 
the troubleshooting guide to solve some of the most common operational 
problems.
Maintenance
Preventive maintenance
Maintenance of the SAILOR 6300 MF/HF DSC can be reduced to a weekly 
check and a maintenance check at each visit of the service staff. Inspect 
the radio for mechanical damages, salt deposits, corrosion and any foreign 
material. Due to its robust construction and ruggedness the radio has a long 
lifetime. Anyway it must carefully be checked at intervals not longer than 
12 months - dependent on the current working conditions.
Salt deposits
Antenna system, including Antenna Tuning Unit, whip antenna, feeder wire 
and especially supporting isolators should be checked regularly and kept 
clean to avoid flashovers and reduced output power causing poor radiation.
SAILOR6301_UM.book  Page 53  Friday, June 12, 2015  2:37 PM

Chapter 3:  Service & maintenance
54 Maintenance
In case the indoor equipment has been exposed to sea water there is a risk 
of salt crystallization on the keyboard, knobs and cable connectors on the 
control unit, as well as on cable connectors on the transceiver unit, and they 
may become inoperable. 
Clean the MF/HF radio system with fresh water.
Weekly installation check
Go through the following weekly check procedure:
1. Select a SSB channel or frequency pair, press PTT and check that tune is 
done successfully.
2. If a GPS is connected, check the position and time in the MF/HF display. 
3. Send a DSC test call to an appropriate coast station or ship. 
4. Enter Setup, Diagnostics, Self Test and start the applicable test, noting 
that RF-power will be present during testing. Note that output power is 
above 60W.
DSC self test
To run a loop back DSC self test, do as follows:
1. Press the soft key SETUP. If it is not in the display, press the soft key 
MORE until SETUP appears.
2. Press the arrow soft key  or   to advance to DSC SETUP.
3. Turn the selector knob to select DSC Self Test. Press and turn the 
selector knob to select RUN.
The test will check the ability to encode/decode DSC signalling on RF 
level. The radio will automatically transmit a DSC safety test call to its 
own MMSI number without enabling the transmitter power amplifier. In 
parallel the radio decodes and compares the received call to be the 
same as the transmitted.

functionality does not work correctly — including the ability 
to send or receive a Distress message.
Contact your dealer immediately for further advice.
Note The Cobham Test station can be called if physical location and 
weather permits. 
Select softkey Call. Change Type to Safety Test. Input MMSI: 
219015591, select appropriate band and press softkey send.

making the transmitter antenna sway, etc.
To view system messages, do as follows:
1. Press the soft key SETUP. If it is not in the display, press the soft key 
MORE until SETUP appears.
2. Press the arrow soft key  or   to advance to and select Diagnostics 
and then Log.
3. Turn the selector knob to go to a setting, then press the selector knob to 
view the system setting.
4. Press EXIT to return to normal radio operation.
Note If the message ATU: No Comm. appears in the display during 
normal use, this might be a temporary condition depending on the 
current installation. If the problem  persists, a pop-up message 
with an error message appears in the display.

Self Test
Two different self tests are available: 
• Tx single-band transmission test
• Tx multi-band transmission test
The Tx single Band test performs a tone transmitter test on the current TX 
frequency shown in the display.
The output of this test is the transmitted power and the battery voltage. 
Note that the output power is not calibrated, so the power figure may only 
be used as a guideline. The battery voltage should not drop significantly 
during this test, as this indicates a poor installation (e.g. thin wires, etc.)
The Tx Multi Band test is similar to the single band test. However, this test 
automatically transmits on the channel next to all six distress SSB 
frequencies:
• 2182+3 kHz
• 4125+3 kHz
• 6215+3 kHz
• 8291+3 kHz
• 12290+3 kHz
• 16420+3 kHz
If you exit the test before it is finished, a system status message will not be 
added to the diagnostics log.
ATU status
In the ATU status menu the following items are present:
• ATU software version
• ATU Selftest respons in the format 0x00. This code should be 
mentioned if any service inquiries regarding output power or antenna 
tuner are made
Note This test transmits a short test signal at full power — the radio 
operator needs to verify that the channel is free from any traffic 
before starting the test!

• ATU SWR ratio. For the 6384B tuner the standing wave ratio of last tune 
session is recorded
• ATU TX Relays. For the 6384B tuner, the actual settings of relays in the 
different banks of the tuner are shown. This information can be used 
when making technical inquiries regarding power and tuning.
ATU RX AMP
This can disable the RX low noise amplifier for MF/HF system 6000A only.

FEC Forward Error Correction. A system of error control for data 
transmission, whereby the sender adds redundant data to its 
messages, also known as an error-correcting code. This allows 
the receiver to detect and correct errors without the need to 
ask the sender for additional data. The advantages of forward 
error correction are that a back-channel is not required and 
retransmission of data can often be avoided.
