BASIC RADIO COMMUNICATION PROCEDURES

Distress or emergency calls may be made either manually or automatically.

Sending distress calls automatically uses the Digital Selective Calling (DSC)

functions of your transceiver and requires an operating and properly con-

nected navigation receiver. The following procedures are for sending voice

distress messages manually. Sending an automatic distress call is described

in the DSC section of this manual.

Using Channel 16

Channel 16 is the Calling and Distress channel. An emergency may be de-

fined as a situation that threatens human life or property. In such situa-

tions, make sure your transceiver is turned On and set the channel selector

to Channel 16. Then use the following procedure to make a distress call.

The total transmission should not exceed 1 minute.

1. Press the microphone Push To Talk button. Speak slowly and clearly

into the microphone: “Mayday, Mayday, Mayday, this is your

vessel’s name, your vessel’s name, your vessel’s name”.

2. Then repeat once: “Mayday, your vessel’s name”.

3. Continue by reporting your position in latitude and longitude or by

reporting your bearing (true or magnetic, specify which) and dis-

tance from a prominent or well known landmark, geographic fea-

ture or aid to navigation.

4. Explain the nature of your emergency (fire, sinking, collision,

grounding, health condition, injury, etc.).

5. Report the kind of assistance you require (fire, medical aid, pumps,

etc.).

6. State the number of people aboard and the condition of any injured.

7. Estimate the seaworthiness and condition of your vessel.

8. Describe your vessel: length, type, color and any distinguishing fea-

ture.

9. End the message by saying “Over”. Release the Push To Talk but-

ton and listen for a reply.

10. If there is no reply, repeat the above message procedure. If there is

still no response, try another channel.

SX 35 DSC

Calling Another Vessel

Channel 16 may be used to establish initial contact with another vessel.

However, its most important use is for voice emergency messages. Chan-

nel 16 must be monitored at all times except when engaged in actual com-

munication on another channel. Channel 16 is monitored by international

search and rescue (SAR) authorities, National Coast Guards and by other

vessels. Use of Channel 16 for calling or hailing must be limited to initial

contact only. Calling should not exceed 30 seconds and may be repeated 3

times at 2 minute intervals.

Prior to making contact with another vessel, determine which channel will

be used for continued communication after the initial contact. Channels 68

and 72 (see Channel Assignment tables) are two channels available for non-

commercial (recreational) communication. Monitor the desired channel for

traffic and, when clear, switch to Channel 16 to make initial contact.

Listen for traffic on the Calling Channel (16). If clear, press the Push To Talk

(PTT) button on the microphone. Speak the name of the vessel you are

calling followed by “this is” and the name of your vessel and your call sign.

Release the PTT and listen for a reply. When the other vessel returns your

call, acknowledge the call with “go to”, the number of the new channel and

“over”. Switch to the new channel and listen for traffic. If necessary, wait

for traffic to clear, and then call the other vessel. As communication pro-

ceeds, end each transmission with “over”. When communication with the

other vessel is completed, end the last transmission with your call sign and

the word “out”. It is not necessary to end each transmission with your call

sign, just give your call sign at the beginning and end of each contact.

Remember to switch to Channel 16 when not actively communicating on

another channel.

Telephone Calls

You may use your SX 35 DSC transceiver to make telephone calls to per-

sons on shore. To do so requires the services of marine operators who oper-

ate on designated Public Correspondence channels. There are several chan-

nels designated for this type of traffic and to determine the channel being

used in your area, ask someone with local knowledge, contact a Harbor

Master or other marine authority.

SX 35 DSC

Call the marine operator and identify yourself with your vessel’s name.

Normally you contact a marine operator on their working channel rather

than making initial contact on Channel 16. The marine operator will ask for

your intentions and establish a payment method for the call (collect, credit

card, etc.). When arrangements are complete, your radio communication

will be patched into the telephone line. In conversing with a person on the

phone it is important to use normal radio communication procedures. You

should say “over” and release the PTT button at the end of each transmis-

sion. Both parties cannot speak simultaneously as on normal telephone calls.

Usually there is a fee for marine operator services which is charged in addi-

tion to any other charges associated with the call.

Prohibited Communication

The following communications are prohibited by regulations and violators

are subject to penalties.

•

False distress or emergency messages (including false DSC distress).

Messages to “any vessel” except in emergencies and radio tests.

Messages to or from a vessel on land.

Transmission while on land.

Obscene, indecent, or profane language.

SX 35 DSC

INSTALLATION

Transceiver

Your SX 35 DSC Transceiver is designed to withstand the rigors of the ma-

rine environment. However, selecting a mounting location affording some

protection from the elements will prolong the life of connectors, controls

and the liquid crystal display (LCD).

Select a location within easy reach and view of the operator and away from

your vessel’s compass. Locate the microphone to avoid entanglement with

steering or engine controls, both when in use and when stowed. Also, con-

sider routing of antenna, power and NMEA interface cables. Mount the

transceiver securely to a solid surface.

Antenna

Proper installation of a quality VHF antenna is very important to reliable

radio communication. A good quality unity gain antenna is recommended

for maximum range performance. In general, antennas should be located

as high as practical and separated as much as possible from other antennas

and structures. The minimum distance to other objects is 1 meter. Route

the antenna cable away from other electronic equipment and do not bundle

the antenna or power cable with other wiring, especially transducer cables

for depth sounders and fish finders. For cables longer than 10 meters, RG-

8/U coaxial cable must be used. Mount the antenna and install the

connector(s) in accordance with manufacturers instructions. Connect the

antenna cable to the RF output connector on the rear panel of the trans-

ceiver.

Power Connection

CAUTION

Reverse polarity connections can damage your transceiver

The power cable for you transceiver must be connected to the ships main

power buss. Use the 6.3 Amp in-line fuse provided. Connect the Red wire

to the positive (+) terminal and the Black wire to the negative (—) terminal.

Connect the barrel terminals on the power cable to the matching color wires

and terminals extending from the rear panel of the transceiver.

SX 35 DSC

NMEA Cable

In order for the position reporting features of your SX 35 DSC transceiver to

function, an operating GPS navigation receiver must be connected to your

transceiver. The supplied data cable plugs into the 8 pin connector on the

transceiver’s rear panel and the other end connects to the NMEA data out-

put from your GPS navigation receiver. Your GPS must output the $GPRMC

NMEA data sentence. Refer to your navigation receiver manual for infor-

mation about its NMEA output settings and connections.

External Speaker Connection

Provision for connecting and external speaker is provided on the rear panel.

Use an 8 Ohm speaker rated for at least 3 Watts and suitable for the environ-

ment at the chosen location.

Volume and Squelch

The VOLume and SQuelch controls have concentric knobs. The outer ring

knob controls squelch and the inner knob controls volume. They are inde-

pendent controls but work together to control audio output from the speaker.

The volume control sets the loudness of sound from the speaker and the

squelch control is used to mute background noise when no received signals

are present.

SX 35 DSC

To properly set the VOL and SQ controls:

•

Rotate the SQ control fully CCW.

Rotate the VOL control CW until background noise is plainly heard.

Slowly rotate the SQ control CW until the noise is muted (squelched).

Then adjust the control slightly more CW (approximately 1/8 turn). Use

care not to set the SQ control more CW than necessary or weak signals

may not be heard.

Some channels exhibit more background noise than others, so it may be

necessary to readjust the squelch setting when changing channels or when

scanning.

Channel Selection

When the transceiver is turned On, the Primary Calling Channel (channel

16) is selected.

There are three ways to change channels:

OPERATING PROCEDURES

Primary Calling Channel

VHF Channel 16 (156.8 MHz) is the Distress Safety and Primary Calling

Channel. All vessels, not actively engaged in communication, are required

to maintain a listening watch on Channel 16.

Transmitting

The transmitter is activated, for normal voice communications, by pressing

the Push To Talk (PTT) button on the microphone. Always listen for mo-

ment on a channel before transmitting. If the channel is busy, do not trans-

mit until the channel is clear. For DSC calling and Distress calls, the trans-

mitter is activated automatically during the appropriate operating proce-

dure. After DSC contact is established, proceed as in normal voice commu-

nication. Continuous transmitter operation is limited to five minutes and

the transmitter will automatically stop.

To establish normal voice communication:

•

Press the

key to select the Primary Calling Channel. The Pri-

mary Calling Channel is 16. The Primary Calling Channel number ap-

pears in the upper left corner of the display.

•

Listen on the Primary Calling Channel to make sure the channel is clear.

Press the PTT button. Speak directly into the microphone in a normal

tone of voice --clearly--distinctly. Say “(name of vessel being called)

THIS IS (your vessel’s name and call sign).”

•

Release the PTT button and listen for a reply.

Once contact is made on the Primary Calling Channel, each vessel must

switch to a working channel to continue conversation. Refer to the chan-

nel chart for proper usage.

•

After communication is completed, each vessel must give its call sign

or vessel name and switch to the Primary Calling Channel and resume

listening watch.

SX 35 DSC

Working Channel Recall

Rather than using the SELECT knob or microphone keys to change chan-

nels, this feature allows quick switching between the last working channel

and the current primary channel.

To quickly switch between the last working channel and the Primary Call-

ing Channel:

•

Use the SELECT knob or microphone keys to select a working channel,

such as channel 68.

•

Press the

key momentarily. The current primary channel num-

ber appears in the channel number display.

•

Press the 16 key again momentarily. The working channel number

appears in the display. Each time the key is pressed, channel selection

toggles between the primary channel and the working channel.

Transmitter Power Setting

The transmitter has two power settings, 25 watts or 1 watt, which are indi-

cated by HI or LO appearing in the upper line of the display. The normal

power setting is HI for all channels where 25 watts is allowed. Use the 1

watt setting for communication with nearby vessels (bridge-to-bridge) or

facilities (drawbridges).

HI/LO

•

Press the

key to toggle transmitter power between 25 watts and

1 watt output.

SPECIAL NOTE

Channels 15 and 17 are restricted to 1 watt maximum power and will

cause the error beep if the HI/LO key is pressed.

Channel Scanning

There are three channel scanning modes; Priority Scan, All Scan and Memory

Scan. In the Priority Scan mode, Channel 16 is checked for activity every 2

seconds, even if, the scan is halted by traffic on a working channel. When

scanning is halted by traffic, the scan pauses while the channel is active.

Scanning resumes, after a brief delay when the channel is clear. If the PTT

is pressed, in reply to a received signal, scanning is cancelled.

DSC OPERATION

The Digital Selective Calling (DSC) functions of your SX 35 DSC transceiver

add convenience and safety to your VHF communication capability. DSC

allows you to contact other DSC equipped vessels and shore stations by

selecting their names from your personal call directory, choosing a call type,

and pressing a key. In an emergency, pressing one button will send your

vessel ID and current position to search and rescue (SAR) authorities and

other DSC equipped vessels. Distress calls are covered first. Then, normal

calling procedures are described.

Position reporting requires connection to an operating GPS navigation re-

ceiver or manually entered Lat/Lon coordinates. If data from your GPS is

lost, 3 quick error beeps are sounded and the following warning screen ap-

pears in the display after 23.5 hours.

MMSID

SPECIAL NOTE

In order to use DSC functions, you must obtain a nine-digit maritime

mobile service identity (MMSI) and program it into your transceiver be-

fore you transmit.

Prior to obtaining an MMSI, you will be asked to provide certain informa-

tion about your vessel and communication equipment. Contact the govern-

ment radio communication authorities of your country for licensing and

MMSI information. It is important that you obtain an MMSI, because Na-

tional Coast Guard authorities use this information to help speed search

and rescue operations.

The procedure for entering your MMSI is described in the MMSID Set topic

of the Operating Procedures section.

Normal DSC Calls

Your SX 35 DSC can transmit four types of DSC calls; Distress, All Ship’s,

Individual, and Group. Except for Distress, each call type is subdivided

into one or more priorities.

All Ship’s type transmits two priorities: Urgency and Safety.

Individual type transmits one priority: Routine.

Group type transmits one priority: Routine.

A normal DSC call may be originated from your vessel to another DSC

equipped vessel or to a coast station, or you may reply to a DSC call sent by

another vessel or a coast station. Outgoing calls are made either by select-

ing a vessel or station name from your directory or by manually entering

the vessel or station MMSID number.

Replies to any incoming call type can be made directly from the call log.

The call log (LAST CALL) holds thirty two entries and the last call received

is on top of the list. If the call log is full, the oldest entry is lost.

Individual DSC Call

Individual calls can be made to another vessel or to a coast station. It is

important to be able to differentiate between the two. When calling another

vessel, the communication channel is specified in the call by the calling ves-

sel. If communicating with a coast station, it is the coast station in its ac-

knowledgment, that determines the channel. Your SX 35 DSC transceiver

transmits Routine individual calls, but receives both Routine and Safety in-

dividual calls.

Directory Call

Directory calls are made by selecting a vessel or station name from the call-

ing directory. The calling directory holds thirty two of your previously

entered names that you routinely contact during normal boating activities.
