1 GENERAL
1.1 Introduction
The RD68 is a combined VHF radio and Class D Digital Select-
ive Calling (DSC) unit. It supports the latest GMDSS require-
ments for non-SOLAS vessels from the International Maritime
Organization (IMO). This will enable you to make digitally
selected calls, which are quicker and simpler to make than tra-
ditional voice calls using channel 16. Should a distress situation
occur, with the RD68 you can quickly raise an alert, indicating
your identity, your position, and automatically establish distress
communication on the emergency voice channel.
The RD68 is robustly constructed using a pressure die-cast alu-
minum case for effective heat dissipation, ensuring maximum
transmission performance even after many hours’ constant use.
Thank you for choosing Simrad!
If you are pleased with your VHF, we hope you will be interest-
ed in our range of marine electronic equipment, which is manu-
factured to the same high standards as the RD68. Please contact
your nearest Simrad Agent for a catalog showing our increasing
range of high tech navigational instruments, GPS, Autopilots,
Radar, Fishfinders and VHF radio sets.
Simrad operates a policy of continual development and reserves
the right to alter and improve the specification of their products
without notice.

1.2 Licensing
Note Prior to use please check the national licensing requirements
for operators.
In the UK license applications and queries should be made to
the following authority:
Ship Radio Licencing
Radio Licencing Centre
The Post Office
PO Box 1495
Bristol BS99 3QS
Website: www.radiolicencecentre.co.uk/rlc
A set may only be operated by or under the supervision of the
holder of a Marine Radio Operators Certificate of Competence
and Authority to Operate. This is awarded on completion of the
Marine Short Range Certificate course administered by the Royal
Yachting Association:
Royal Yachting Association
RYA House
Ensign Way
Hamble
Southampton SO31 4YA
Website: www.rya.org.uk
Tel. 0845 345 0400
Holders of the Restricted Certificate of Competence in Radio-
telephony (which covers MF/HF SSB, etc.) do not need a sepa-
rate VHF certificate.
In all other countries, please contact your regional authority for
information.
Note North American Users – To meet FCC (Federal Communica-
tions Commission) rules on Radio Frequency Exposure, it is
recommended that the VHF antenna is mounted at least 3 m
(10 ft) away from any area accessible to any personnel on board.
If this distance is achieved by vertical separation, the antenna
must be at least 5 m (16.5 ft) above deck. This guideline applies
only to antennas not exceeding 9dBi gain.
WARNING Failure to observe these recommendations may
expose those within the MPE (maximum permit-
ted exposure) radius of 3 m (10 ft) to RF absorp-
tion levels that exceed the FCC safe limits.

1.3 Entering MMSI numbers
At the time of issue of your vessel’s radio license, an MMSI
(Maritime Mobile Service Identifier) must be requested. This is
a nine-digit number which must be permanently entered into the
RD68 when the radio is first set up, otherwise the DSC func-
tions cannot be accessed.
Note If the boat or the RD68 are subsequently sold, the radio must be
returned to an authorized Simrad agent for the MMSI number
to be erased and the new owners MMSI number entered.
For licensing details, please refer to section 1.2.

2 OPERATION
2.1 General
The RD68 VHF is very simple to operate, with the controls
falling into five groups:
1. The rotary Volume (On/Off) & Squelch controls.
2. The alphanumeric keypad used to select the channel, MMSI
number, etc.
3. The dedicated controls, for commonly used functions such
as output power, Dual Watch, and channel 16 select, etc.
4. The four softkeys to the right of the display are multi-
function keys whose function changes depending on which
menu is displayed. The label showing the current function for
each softkey appears on the right side of the display (see left).
5. There is also a Distress button under a sliding cover. This
must only be used in an emergency (see section 5.1).
The radio functions are split into two main modes:
• Radio mode allows access to the standard VHF radio func-
tions, such as Tri-Watch, scanning, etc.
• DSC mode covers the digital selective calling functions.
These modes are toggled by pressing softkey 1 (labeled DSC or
RAD).
At any stage of the DSC mode menu structure, pressing the DSC
softkey will return to the DSC mode main menu. At any stage
of the DSC mode menu structure, pressing the C key will can-
cel any unconfirmed action, or step back one level in the menu
structure.
Note Some menu options will only be displayed if the relevant infor-
mation is available.
If the radio is receiving NMEA GPS data, the current Lat/Long
will be displayed when in DSC mode, and the time will be dis-
played in both Radio and DSC modes in 24-hour UTC (GMT)
format (the local time can also be entered).
2.2 Rotary controls
Switch the radio on by turning the VOLUME knob clockwise.
To increase the volume, turn the knob further clockwise. Turn
the knob fully counterclockwise to switch off.
The SQUELCH knob is used to adjust the receiver muting
threshold (squelch) level. To cut out weaker signals, increase
the squelch until the background interference noise disappears.
To receive weaker signals, decrease the squelch.

2.7 Making a Distress Alert call
WARNING This call should only be made if the vessel is in a
genuine distress situation. It is an offense to send
a Distress Alert call if the vessel or crew are not in
grave and imminent danger (see section 5.1).
The DISTRESS button is located under a protective cover that
must be slid back before the button can be pressed. Press the
DISTRESS button to access the Distress Alert screen:

To send the call, press and hold the DISTRESS key for five
seconds. A countdown to the transmission will be displayed.
Release the key at any time during this countdown to abort the
transmission and press C to return to the main menu.
The Distress Alert transmission contains the following data:
• The vessel’s MMSI
• The vessel’s position (either from the NMEA 0183 input, or
manually entered)
• The time (from NMEA or manual)
• The nature of the distress
Note If the boat’s position and time are not being received via the
NMEA interface, then the display will allow this data to be
entered manually (refer to section 3.2 for more details).
After the Distress Alert has been sent, the RD68 will tune to
channel 16 and will automatically repeat the alert approximately
every four minutes, until either an acknowledgment is received
or C is pressed (it is not recommended that the Distress Alert is
cancelled manually by pressing C, unless you are requested to
do so by the rescue authorities).
While the Distress Alert remains active, an intermittent alarm
will continue to sound.
When an acknowledgment is received from the Rescue Co-
ordination Center, this will automatically cancel the Distress
Alert transmission. The subsequent rescue co-ordination will be
performed using the voice working channel.

3.6 Second country mode
In countries where it is permitted, the RD68 can operate on a
secondary set of channels, such as the USA channels:
Note Channel sets available will depend on programming. Please
enquire with your national licensing authority for details of
permitted channel sets in your country (see also section 5.4).
Note The radio will revert to the International channel set when it is
switched off.
3.7 Speaker mute (handset models only)
On radios fitted with a handset, lifting the handset from the cra-
dle will normally mute the loudspeaker. However, this can be
disabled, so that the loudspeaker will remain on when the hand-
set is lifted, and incoming transmissions will be heard both in
the handset earpiece and the loudspeaker.

4 INSTALLATION
4.1 VHF installation
The radio should be sited so that engine noise and vibration or
other background noise do not make it difficult for the operator
to hear.
Although the RD68 radio is waterproof when flush mounted, it
is recommended that it is not installed where it will be exposed
to continuous direct sunlight, as this will eventually damage the
LCD display.
As microphones and loudspeakers contain powerful magnets,
the radio should not be installed within 1 m (3 ft 3 in) of any
compasses, whether magnetic or electronic.
The fins on the back of the case act as a heatsink to dissipate
heat generated by the set when in use, which maintains the high
efficiency of the radio. The free circulation of air is essential –
when mounting the radio in an enclosed space, ensure that the
space is vented.
The VHF is supplied with a reversible mounting bracket. This
can be used to mount the VHF on the chart table or on an over-
head bulkhead (Fig 4.1). The bracket is fixed in place using four
No. 10 x 3/4 in screws (supplied). Before installing, ensure that
there is at least 88 mm (3.5 in) vertical clearance and 100 mm
(3.9 in) horizontal clearance behind the bracket to allow the
radio to fit (Fig 4.2).

E03912 Issue 2.0
The radio is fixed to the bracket using a simple clamp arrange-
ment. The peg on the left side of the radio is slotted into the
hole in the bracket. The clamp on the right side of the radio can
then be slid into the slotted aperture on the bracket and tight-
ened to hold the radio firmly in place (Fig 4.3). The rake angle
of the radio can be adjusted by slackening the clamp.
1. Fit locating peg (left side) into hole in bracket
2. Slide locking clamp (right) into slot in bracket
3. Tighten clamp

An alternative mounting method is to use the flush mounting kit
(FMB1000:BK, supplied separately). This allows the radio to
be neatly installed inside a bulkhead, so that only the fascia of
the radio is visible.
For more details of this and other accessories available,
please refer to section 5.6.
Instruction Manual
39
E03912 Issue 2.0
The RD68 has five electrical connections – the handset/fistmike
socket is on the front panel below the LCD display (Fig 4.4A).
The other four are situated on the back of the case: the antenna
socket is on the left (Fig 4.4B); DC power is supplied to the set
via a two-core flying lead (Fig 4.4C); the NMEA input connec-
tions (Fig 4.4D) allow a GPS to be interfaced, below which is a
3.5 mm jack socket for an optional extension speaker (Fig 4.4E)
– this is covered by a weather plug when not in use.
The VHF requires a 12V DC supply to operate and is supplied
with a power lead which incorporates an in-line 7.5 Amp fuse.
This lead should be connected to the vessel’s power supply,
keeping the cable runs as short as possible. Although the radio
draws very little current when receiving, a heavier current is
drawn when transmitting, which may result in a voltage drop if
long cable runs of inadequate core diameter are used. If the sup-
plied power lead is not long enough, an extension of up to 3 m
(10 ft) can be made using at least 2.5 mm
2
(13 AWG) wire.
The red wire is positive and black is negative. If polarity is
accidentally reversed, the set is protected, but the fuse will blow.
Ensure that it is replaced with a fuse of the correct 7.5Amp rat-
ing. The radio is designed to be easily removable for storage or
security, so leave an adequate length of cable to ease disconnec-
tion. The flying lead from the rear of the radio can then be
plugged into the power supply lead. Note, that the configuration
of the plug prevents incorrect connection.

RD68 VHF

E03912 Issue 2.0
The antenna is connected to the radio using a standard PL259-
type connector as fitted to most marine antennas. If fitting to an
existing antenna, check that the contacts are not corroded before
connecting, as this will affect the quality of the signal. Ensure
that the retaining collar of the antenna plug is securely tightened
to prevent accidental disconnection.
For NMEA interfacing to an external navigation source (e.g. a
GPS, Loran or chartplotter) the RD68 is supplied with a 1 m
cable assembly which plugs into the lead at the back of the
radio. The other end is connected to the navigator as follows:
Wire color Navigator connections:
Red NMEA OUT Data (+)
Blue NMEA OUT Common (-)
Fig 4.5 - Linking to navigation source
Red -
Data Out
Blue -
Common
Note If the navigator does not have a dedicated NMEA common ter-
minal, the blue wire should be connected to the 0 V terminal of
the navigator.
The extension speaker socket takes a standard 3.5 mm jack plug.
The speaker used must have a minimum impedance of 8.
4.2 Antenna installation
The most important factor in the performance of the radio will
be the quality and positioning of the antenna. Most recorded
problems with VHF radios are related to poor antenna siting,
faulty cabling, poor quality cable joints, and low voltage supply.
Even a VHF as highly advanced as the RD68 cannot compen-
sate for these factors. Therefore, when replacing an existing
VHF installation, it is important that the antenna is thoroughly
checked for any faults or damage before use.
As the range of VHF signals are governed by line of sight (see
section 5.3), the antenna should be placed as high as possible,
while remaining clear of any metallic objects that could influ-
ence the resonance of the antenna.
Instruction Manual
41
E03912 Issue 2.0
The most popular antennas for marine use are 1 m (3 ft 3 in)
long. On sailboats these are usually mounted on the masthead,
where the length of the antenna keeps it clear from the naviga-
tion lights and windvanes, etc. This type of antenna can also be
mounted on the cockpit roof or garage of power boats.
Longer whip antennas are recommended for larger boats – these
radiate the same total power as smaller antennas, but concen-
trate it into a narrower beam, which is advantageous on a tall
mast at extreme range where concentrating the available power
into a narrow horizontal beam becomes more important.
However, if the antenna is not vertical when transmitting, the
beam will be angled either too high or too low (Fig 4.6).
Fig 4.7 - Effect of heel on range of 1 m marine antennas
Fig 4.6 - Effect of heel on range of longer whip antennas
Here the wider beam of the shorter antenna will be more uni-
versally effective, although the signal will be weaker (Fig 4.7).
Therefore, for vessels with a large heel angle (small sailboats) a
short masthead antenna would be a better choice. Your local
agent should be able to provide specific advice on antenna
choice for the vessel it is to be fitted to.
WARNING The antenna coaxial cable and any connectors
used must be rated at 50 Ω. Under no circum-
stances should standard domestic TV cable and
connectors be used. Incorrectly rated cabling and
connectors could result in power not reaching the
antenna, but power could also be reflected back
into the radio, damaging it in the process.
RD68 VHF
42
E03912 Issue 2.0
The quality of any connections and integrity of the cable (with-
out breaks in the sheathing) will directly affect the performance
of the radio. Poor soldering or corrosion of the terminals can im-
pair performance. We recommend that screw or crimp terminal-
type connectors are not used for any through-deck fittings – a
good quality waterproof solder terminal connector will be less
susceptible to poor connection due to corrosion of the contacts.
Note If the RD68 detects a problem with the antenna or antenna con-
nections, the display will show ANT when the PTT key is press-
ed. To avoid possible damage to the radio the antenna should
be checked immediately for any damage or poor connection.
4.3 Electrical interference suppression
Interference generated by the alternator of the engine may occa-
sionally cause problems. The RD68 has been designed to mini-
mize the effects of outside interference. However, precautions
should still be taken – route the power supply and antenna
cables away from the engine compartment. The cable run should
not be down the same trunking as other cables carrying high
current. The antenna cable should also be kept separate from the
radio’s power cable.
Engines with spark ignition—and also some refrigerators—
should be fitted with suppressors. Your local agent should be
able to give advice on this, and also supply suppression kits
where necessary.

5 APPENDIX
5.1 Operating procedures
The following operating procedure summary has been proposed
by the UK Maritime and Coastguard Agency. It is not exhaus-
tive and should not be regarded as a replacement for informa-
tion provided by the proper two-day VHF/DSC training course
required for all UK VHF license holders.
5.1.1 Sending a Distress Alert
1. Send a Distress Alert call (see section 2.7).
2. Wait approx. 15 seconds for a DSC acknowledgment from
the Coastguard or a ship station.
3. On receipt of a DSC acknowledgment, or after about 15
seconds, transmit the following distress call on channel 16:
Mayday, Mayday, Mayday”
“This is (name of vessel, repeat three times)”
“Mayday (MMSI number and name of vessel or callsign –
Position – Nature of distress – No. of persons on board)”
“I require immediate assistance”
“Over.”
If the vessel is not in grave and imminent danger, an All Ships
Urgency call followed by a spoken “Pan Pan” or a routine call
to the nearest Coastguard station may be more appropriate.
WARNING It is a prosecutable offense to initiate a Distress
Alert call for any other reason than that the ves-
sel and/or crew is in grave and imminent danger.
5.1.2 Acknowledging and relaying a
Distress Alert
When a DSC Distress Alert is received, an audible alarm will
sound. Immediately cease any transmission that may interfere
with distress traffic and continue a watch on channel 16.
If there is no DSC acknowledgment from a coast station or ship,
after a short interval acknowledge by voice on channel 16:
“Mayday (MMSI of vessel in distress, repeat three times)
“This is (name of own vessel, repeat three times)
“Received Mayday (state the assistance you can give)”
“Over.”
A similar response should be given to a distress relay, using the
words “Mayday Relay” instead of “Mayday”.
RD68 VHF
44
E03912 Issue 2.0
5.1.3 Cancelling a Distress Alert
If a DSC Distress Alert is sent accidentally, cancel it immediate-
ly on the RD68 by pressing the C button to prevent repeats, then
make the following announcement on channel 16:
“This is (name of vessel, callsign, MMSI)
“Cancel DSC Alert sent (date & time UTC)”
“Over.”
DO NOT simply cancel the DSC alert without verbally cancel-
ing it as well, otherwise the rescue authorities will not be aware
that this is a false alarm.
5.1.4 Alerting all vessels within range
If the vessel is outside of coast radio range and needs to issue a
safety warning to all vessels within radio range, transmit an All
Ships Safety call by DSC. After about 15 seconds transmit on
channel 16 the safety call and message as follows:
“Securité, Securité, Securité”
“All stations (or called station – repeat three times)”
“This is (MMSI and name or callsign of own vessel –
repeat text of safety message) – Over.”
5.1.5 Calling a coast radio station
Enter the MMSI of the station into the RD68, either manually,
or from the directory. When the call is acknowledged, the work-
ing channel for voice communication will be indicated and the
RD68 will automatically switch to that channel. Make a voice
call as normal.
5.1.6 Making an intership call
Enter the vessel’s MMSI into the RD68, either manually, or
from the directory. Before sending the call, enter the intership
channel to be used for subsequent communication. When the
alarm sounds on the called vessel, its operator should acknowl-
edge by DSC, then respond by voice on the selected channel.
If the MMSI number of the vessel is not known, call as now on
channel 16. If no response is received, call on channel 13 (this
is the GMDSS bridge-to-bridge communication channel).
5.2 NMEA sentences received
The following NMEA0183 sentences are processed by the
RD68 in order to transmit the boat’s position when a Distress
Alert is initiated:
NMEA version 2.0 – GGA, GLL, RMC.
Instruction Manual
45
E03912 Issue 2.0
5.3 Transmission range
Because VHF signals travel in a straight line and are not reflect-
ed back off the ionosphere as lower frequency signals are, the
range of VHF signals is limited to ‘line of sight’, beyond which
other vessels pass behind the curve of the Earth.
Therefore, the range will increase greatly the higher above sea
level the antenna is positioned, as Fig 5.1 illustrates (assuming
maximum transmission power is used):
The typical ship-to-ship range of a fixed VHF radio, such as the
RD68, with a masthead antenna will be approximately 20 km
(12 miles). This will increase as height above sea level increas-
es, or if the other radio users antenna is at a greater height –
note, that the range between the yacht with the antenna mounted
on a 9 m (30 ft) mast and the shore station increases to 46–53 km
(29–33 miles).

5.10 Service & Warranty
Your radio should seldom need servicing, although it will bene-
fit from an application of silicone or Teflon grease to the anten-
na and mike sockets each season. The equipment should be reg-
ularly checked by making routine calls to other stations. On an
annual basis, test the DISTRESS button by pressing it ONCE.
This will display the Distress Alert screen and ensure that the
button is functioning. Press C to return to the main screen – DO
NOT HOLD DOWN THE DISTRESS BUTTON.
The unit is guaranteed for 2 years from date of retail sale. If it is
necessary to have the unit repaired, return it carriage prepaid to
the agent in the country of purchase with a copy of the receipted
invoice showing the date of purchase. Where possible, return all
the components, unless you are certain that you have located the
source of the fault. If the original box is not available, ensure
that it is well cushioned in packing – the rigors of freight han-
dling can be very different from the loads encountered in the
marine environment for which the unit is designed.
For worldwide Warranty details, please refer to the Warranty
Card supplied with this unit.
