1 GENERAL

1.1 IntroductionThe 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 MaritimeOrganization (IMO). This will enable you to make digitallyselected calls, which are quicker and simpler to make than tra-ditional voice calls using channel 16. Should a distress situationoccur, with the RD68 you can quickly raise an alert, indicatingyour identity, your position, and automatically establish distresscommunication on the emergency voice channel.

The RD68 is robustly constructed using a pressure die-cast alu-minum case for effective heat dissipation, ensuring maximumtransmission 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 contactyour nearest Simrad Agent for a catalog showing our increasingrange of high tech navigational instruments, GPS, Autopilots,Radar, Fishfinders and VHF radio sets.

Simrad operates a policy of continual development and reservesthe right to alter and improve the specification of their productswithout notice.

2 OPERATION2.1 General

The RD68 VHF is very simple to operate, with the controlsfalling 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 whichmenu is displayed. The label showing the current function foreach softkey appears on the right side of the display (see left).

5. There is also a Distress button under a sliding cover. Thismust 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 orRAD).

At any stage of the DSC mode menu structure, pressing the DSCsoftkey will return to the DSC mode main menu. At any stageof the DSC mode menu structure, pressing the C key will can-cel any unconfirmed action, or step back one level in the menustructure.

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/Longwill 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 controlsSwitch the radio on by turning the VOLUME knob clockwise.To increase the volume, turn the knob further clockwise. Turnthe knob fully counterclockwise to switch off.

The SQUELCH knob is used to adjust the receiver mutingthreshold (squelch) level. To cut out weaker signals, increasethe squelch until the background interference noise disappears.To receive weaker signals, decrease the squelch.

To send the call, press and hold the DISTRESS key for fiveseconds. A countdown to the transmission will be displayed.Release the key at any time during this countdown to abort thetransmission and press C to return to the main menu.

The Distress Alert transmission contains the following data:

The vessels MMSI The vessels position (either from the NMEA 0183 input, or

manually entered) The time (from NMEA or manual) The nature of the distress

Note If the boats position and time are not being received via theNMEA interface, then the display will allow this data to beentered manually (refer to section 3.2 for more details).

After the Distress Alert has been sent, the RD68 will tune tochannel 16 and will automatically repeat the alert approximatelyevery four minutes, until either an acknowledgment is receivedor C is pressed (it is not recommended that the Distress Alert iscancelled manually by pressing C, unless you are requested todo so by the rescue authorities).

While the Distress Alert remains active, an intermittent alarmwill continue to sound.

When an acknowledgment is received from the Rescue Co-ordination Center, this will automatically cancel the DistressAlert transmission. The subsequent rescue co-ordination will beperformed using the voice working channel.

3.6 Second country modeIn countries where it is permitted, the RD68 can operate on asecondary set of channels, such as the USA channels:

Note Channel sets available will depend on programming. Pleaseenquire with your national licensing authority for details ofpermitted channel sets in your country (see also section 5.4).

Note The radio will revert to the International channel set when it isswitched 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 bedisabled, so that the loudspeaker will remain on when the hand-set is lifted, and incoming transmissions will be heard both inthe handset earpiece and the loudspeaker.

4 INSTALLATION4.1 VHF installation

The radio should be sited so that engine noise and vibration orother background noise do not make it difficult for the operatorto hear.

Although the RD68 radio is waterproof when flush mounted, itis recommended that it is not installed where it will be exposedto continuous direct sunlight, as this will eventually damage theLCD display.

As microphones and loudspeakers contain powerful magnets,the radio should not be installed within 1 m (3 ft 3 in) of anycompasses, whether magnetic or electronic.

The fins on the back of the case act as a heatsink to dissipateheat generated by the set when in use, which maintains the highefficiency of the radio. The free circulation of air is essential when mounting the radio in an enclosed space, ensure that thespace is vented.

The VHF is supplied with a reversible mounting bracket. Thiscan 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 fourNo. 10 x 3/4 in screws (supplied). Before installing, ensure thatthere is at least 88 mm (3.5 in) vertical clearance and 100 mm(3.9 in) horizontal clearance behind the bracket to allow theradio to fit (Fig 4.2).

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 thehole in the bracket. The clamp on the right side of the radio canthen be slid into the slotted aperture on the bracket and tight-ened to hold the radio firmly in place (Fig 4.3). The rake angleof the radio can be adjusted by slackening the clamp.

1. Fit locating peg (left side) into hole in bracket2. Slide locking clamp (right) into slot in bracket3. Tighten clamp

An alternative mounting method is to use the flush mounting kit(FMB1000:BK, supplied separately). This allows the radio tobe neatly installed inside a bulkhead, so that only the fascia ofthe radio is visible.

For more details of this and other accessories available,please refer to section 5.6.

Instruction Manual

39E03912 Issue 2.0

The RD68 has five electrical connections the handset/fistmikesocket is on the front panel below the LCD display (Fig 4.4A).The other four are situated on the back of the case: the antennasocket is on the left (Fig 4.4B); DC power is supplied to the setvia 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 a3.5 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 12 V DC supply to operate and is suppliedwith a power lead which incorporates an in-line 7.5 Amp fuse.This lead should be connected to the vessels power supply,keeping the cable runs as short as possible. Although the radiodraws very little current when receiving, a heavier current isdrawn when transmitting, which may result in a voltage drop iflong 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 mm2 (13 AWG) wire.

The red wire is positive and black is negative. If polarity isaccidentally 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 orsecurity, so leave an adequate length of cable to ease disconnec-tion. The flying lead from the rear of the radio can then beplugged into the power supply lead. Note, that the configurationof the plug prevents incorrect connection.

The antenna is connected to the radio using a standard PL259-type connector as fitted to most marine antennas. If fitting to anexisting antenna, check that the contacts are not corroded beforeconnecting, as this will affect the quality of the signal. Ensurethat the retaining collar of the antenna plug is securely tightenedto prevent accidental disconnection.

For NMEA interfacing to an external navigation source (e.g. aGPS, Loran or chartplotter) the RD68 is supplied with a 1 mcable assembly which plugs into the lead at the back of theradio. 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 ofthe 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 willbe the quality and positioning of the antenna. Most recordedproblems 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 existingVHF installation, it is important that the antenna is thoroughlychecked for any faults or damage before use.

As the range of VHF signals are governed by line of sight (seesection 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

41E03912 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 bemounted on the cockpit roof or garage of power boats.

Longer whip antennas are recommended for larger boats theseradiate the same total power as smaller antennas, but concen-trate it into a narrower beam, which is advantageous on a tallmast at extreme range where concentrating the available powerinto a narrow horizontal beam becomes more important.However, if the antenna is not vertical when transmitting, thebeam 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) ashort masthead antenna would be a better choice. Your localagent should be able to provide specific advice on antennachoice for the vessel it is to be fitted to.

WARNING The antenna coaxial cable and any connectorsused must be rated at 50. Under no circum-stances should standard domestic TV cable andconnectors be used. Incorrectly rated cabling andconnectors could result in power not reaching theantenna, but power could also be reflected backinto 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 performanceof 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 agood quality waterproof solder terminal connector will be lesssusceptible 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 shouldbe checked immediately for any damage or poor connection.

4.3 Electrical interference suppressionInterference 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, precautionsshould still be taken route the power supply and antennacables away from the engine compartment. The cable run shouldnot be down the same trunking as other cables carrying highcurrent. The antenna cable should also be kept separate from theradios power cable.

Engines with spark ignitionand also some refrigeratorsshould be fitted with suppressors. Your local agent should beable to give advice on this, and also supply suppression kitswhere necessary.

5 APPENDIX5.1 Operating procedures

The following operating procedure summary has been proposedby 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 courserequired for all UK VHF license holders.

5.1.1 Sending a Distress Alert1. Send a Distress Alert call (see section 2.7).

2. Wait approx. 15 seconds for a DSC acknowledgment fromthe Coastguard or a ship station.

3. On receipt of a DSC acknowledgment, or after about 15seconds, transmit the following distress call on channel 16:

Mayday, Mayday, MaydayThis 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 assistanceOver.

If the vessel is not in grave and imminent danger, an All ShipsUrgency call followed by a spoken Pan Pan or a routine callto the nearest Coastguard station may be more appropriate.

WARNING It is a prosecutable offense to initiate a DistressAlert 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 aDistress Alert

When a DSC Distress Alert is received, an audible alarm willsound. Immediately cease any transmission that may interferewith 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 thewords Mayday Relay instead of Mayday.

RD68 VHF

44 E03912 Issue 2.0

5.1.3 Cancelling a Distress AlertIf a DSC Distress Alert is sent accidentally, cancel it immediate-ly on the RD68 by pressing the C button to prevent repeats, thenmake 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 awarethat this is a false alarm.

5.1.4 Alerting all vessels within rangeIf the vessel is outside of coast radio range and needs to issue asafety warning to all vessels within radio range, transmit an AllShips Safety call by DSC. After about 15 seconds transmit onchannel 16 the safety call and message as follows:

Securit, Securit, SecuritAll 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 stationEnter 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 theRD68 will automatically switch to that channel. Make a voicecall as normal.

5.1.6 Making an intership callEnter the vessels MMSI into the RD68, either manually, orfrom the directory. Before sending the call, enter the intershipchannel to be used for subsequent communication. When thealarm 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 onchannel 16. If no response is received, call on channel 13 (thisis the GMDSS bridge-to-bridge communication channel).

5.2 NMEA sentences receivedThe following NMEA0183 sentences are processed by theRD68 in order to transmit the boats position when a DistressAlert is initiated:

NMEA version 2.0 GGA, GLL, RMC.

Instruction Manual

45E03912 Issue 2.0

5.3 Transmission rangeBecause VHF signals travel in a straight line and are not reflect-ed back off the ionosphere as lower frequency signals are, therange of VHF signals is limited to line of sight, beyond whichother vessels pass behind the curve of the Earth. Therefore, the range will increase greatly the higher above sealevel the antenna is positioned, as Fig 5.1 illustrates (assumingmaximum transmission power is used):

The typical ship-to-ship range of a fixed VHF radio, such as theRD68, 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 mountedon a 9 m (30 ft) mast and the shore station increases to 4653 km(2933 miles).
