9 OPERATING PRACTICES

9.1 EMERGENCY (CHANNEL 16 USE)

Channel 16 is known as the

Hail and Distress Channel

. An emergency may be defined as a threat to life or property. In such instances, be sure the transceiver is on and set to CHANNEL 16. Then use the following procedure:

1. Press the microphone push-to-talk switch and say “Mayday, Mayday, Mayday. This is , , ” (your vessel's name).

2. Then repeat once: “

Mayday

, ,” (your vessel’s name).

3. Now report your position in latitude/longitude, or by giving a true or magnetic bearing (state which) to a well-known landmark such as a navigation aid or geographic feature such as an island or harbor entry.

4. Explain the nature of your distress (sinking, collision, aground, fire, heart attack, life-threatening injury, etc.).

5. State the kind of assistance your desire (pumps, medical aid, etc.).

6. Report the number of persons aboard and condition of any injured.

7. Estimate the present seaworthiness and condition of your vessel.

8. Give your vessel's description: length, design (power or sail), color and other distinguishing marks. The total transmission should not exceed 1 minute.

9. End the message by saying

“OVER”

. Release the microphone button and

listen.

10. If there is no answer, repeat the above procedure. If there is still no response, try another channel.

9.2 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)

Channel 16 may be used for initial contact (hailing) with another vessel. However, its most important use is for emergency messages. This channel must be monitored at all times except when actually using another channel. It is monitored by the U.S. and Canadian Coast Guards and by other vessels. Use of channel 16 for hailing must be limited to initial contact only. Calling should not exceed 30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy radio traffic, congestion on channel 16 resulting from its use as a hailing channel can be reduced significantly in U.S. waters by using channel 9 as the initial contact (hailing) channel for non-emergency communications. Here, also, calling time should not exceed 30 seconds but may be repeated 3 times at 2-minute intervals.

Page 56

GX2355S Owner’s Manual page 53

Prior to making contact with another vessel, refer to the channel charts in this manual, and select an appropriate channel for communications after initial contact. For example, Channels 68 and 69 of the U.S. VHF Charts are some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to make sure you will not be interrupting other traffic, and then go back to either channel 16 or 9 for your initial contact.

When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish to call and then

“this is”

followed by the name of your vessel and your Station License (Call Sign). When the other vessel returns your call, immediately request another channel by saying

“go to”

, the number of the other channel, and "over." Then switch to the new channel. When the new channel is not busy, call the other vessel.

After a transmission, say

“over”

, and release the microphone's push-totalk (PTT) switch. When all communication with the other vessel is completed, end the last transmission by stating your Call Sign and the word

“out”

. Note that it is not necessary to state your Call Sign with each

transmission, only at the beginning and end of the contact. Remember to return to Channel 16 when not using another channel. Some

radios automatically monitor Channel 16 even when set to other channels or when scanning; see your Owner's Manual.

9.3 MAKING TELEPHONE CALLS

To make a radiotelephone call, use a channel designated for this purpose, The fastest way to learn which channels are used for radiotelephone traffic is to ask at a local marina. Channels available for such traffic are designated

Public Correspondence

channels on the channel charts in this manual. Some examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call the marine operator and identify yourself by your vessel's name, The marine operator will then ask you how you will pay for the call (telephone credit card, collect, etc.) and then link your radio transmission to the telephone lines.

The marine telephone company managing the VHF channel you are using may charge a link-up fee in addition to the cost of the call.

Page 57

page 54 Owner’s Manual GX2355S

9.4 OPERATING ON CHANNELS 13 AND 67

Channel 13 is used at docks and bridges and by vessels maneuvering in port. Messages on this channel must concern navigation only, such as meeting and passing in restricted waters. Channel 67 is used for navigational traffic between vessels. By regulation, power is normally limited to 1 Watt on these channels. Your radio is programmed to automatically reduce power to this limit on these channels. However, in certain situations it may be necessary to temporarily use a higher power. See page 8 (H/L key) for means to temporarily override the low-power limit on these two channels.

9.5 PROHIBITED COMMUNICATIONS

The FCC prohibits the following communications:

n False distress or emergency messages: n Messages to "any boat" except in emergencies and radio tests; n Messages to or from a vessel on land; n Transmission while on land; n Obscene, indecent, or profane language (potential fine of $10,000).

9.6 NOAA WEATHER ALERT TESTING

In the event of a major storm or other appreciable weather condition requiring vessels at sea or other bodies of water to be notified, the NOAA (National Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone that some marine VHF radios can detect. (Refer to Section

5.7 “NOAA WEATHER ALERT” on how to use this feature.) This tone, when detected, will produce a loud beep from the radio speaker to signal that a weather alert is being broadcast.

In order to test this system, the NOAA broadcasts the 1050 Hz tone every Wednesday, sometime between 11 AM and 1 PM. Any marine VHF radio that can detect the weather alert tone, may use this test to verify that this feature is functioning properly,

9.7 DIGITAL SELECTIVE CALLING (DSC)

Digital Selective Calling is a semi-automated method of establishing a radio call, it has been designated by the International Maritime Organization (IMO) as an international standard for establishing VHF, MF and HF radio calls. It has also been designated part of the Global Maritime Distress and Safety System (GMDSS) and it is planned that DSC will eventually replace aural watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts. This new service will allow mariners to instantly send a distress call with GPS position (when connected to the transceiver) to the US Coast Guard and other vessels within range of the transmission. DSC will also allow mariners to initiate or receive distress, urgency, safety and routine calls to or from another vessel equipped with a DSC transceiver.

9.7.1 USCG DSC Watch

The USCG has plans to upgrade its VHF National Distress System (expected by

2005), so at the time of printing only larger vessels that are required to carry VHF DSC radios will be able to hear your distress transmission

9.8 MARITIME MOBILE SERVICE IDENTITY (MMSI)

9.8.1 What is a MMSI?

A MMSI is a nine digit number used on Marine Transceivers capable of using Digital Selective Calling (DSC). This number is used like a telephone number to selectively call other vessels.

9.9 USING DIGITAL SELECTIVE CALLING FEATURES

9.9.1 Distress Call

Transmits a DSC Distress message to all radios equipped to receive a DSC Distress call. Some Standard Horizon radios may be connected to a GPS to also transmit the Latitude, Longitude of the vessel.

9.9.2 Individual Call

This feature allows the user to contact another vessel capable of using DSC and automatically switch the radio to a desired working channel. This feature is similar to calling a desired vessel on CH16 and requesting them to go to another channel.

Page 59

page 56 Owner’s Manual GX2355S

9.9.3 Group Call

This feature allows the user to contact a group or vessels capable of using DSC to automatically switch the radios to a desired working channel for voice communication.

9.9.4 Urgency Call

This call should be used when a vessel may not be truly in distress, but have a potential problem that might lead to a distress situation.

9.9.5 Safety Call

Used to transmit boating safety information to other vessels. This message usually contains information about an overdue boat, a derelict afloat, loss of a navigation aid or an important meteorological message.

9.9.6 Position request

Used to poll another vessel position via DSC and show it on the LCD of the radio.

9.9.7 Telephone Call

Used to automatically place a telephone call through a shore based telephone company. (In the U.S. market contact maritel at 1866 - marinet for subscription details)

9.10 ADDITIONAL DIGITAL SELECTIVE CALLING

INFORMATION

For additional information the USCG has an excellent site that should be visited at www.navcen.uscg.mil/marcoms/gmdss/dsc.html

9.11 ABOUT VHF RADIO

The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with some shore stations available between 161 and 163 MHz. The marine VHF band provides communications over distances that are essentially “line of sight” (VHF signals do not travel well through objects such as buildings, hills or trees). Actual transmission range depends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 25W radio transmission expected distances can be greater than 15 miles, for a portable 5W radio transmission the expected distance can be greater than 5 miles in “line of sight”.

GX2355S Owner’s Manual page 57

9.12 SELECTING AN ANTENNA

Marine antennas are made to radiate signals equally in all horizontal directions, but not straight up. The objective of a marine antenna is to enhance the signal toward the horizon. The degree to which this is accomplished is called the antenna’s gain. It is measured in decibels (dB) and is one of the major factors in choosing an antenna. In terms of effective radiated power (ERP), antennas are rated on the basis of how much gain they have over a theoretical antenna with zero gain. A 3 foot, 3dB gain antenna represents twice as much gain over the imaginary antenna. The length of the antenna you choose, however, must also be related to the size of your boat. Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The longer 8 foot 6dB fiberglass whip is primarily used on power boats that require the additional gain.

9.13 COAXIAL CABLE

VHF antennas are connected to the transceiver by means of a coaxial cable – a shielded transmission line. Coaxial cable is specified by it’s diameter and construction. For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice. For runs over 20 feet but less than 50 feet, the larger RG-8 or RG-213/U should be used for cable runs over 50 feet RG-8 should be used. For installation of the connector onto the coaxial cable refer to the figure below.

To get your coax cable through a fitting and into your boat's interior, you may have to cut off the end plug and reattach it later. You can do this if you follow the directions that come with the connector. Be sure to make good soldered connections.

Page 63

page 60 Owner’s Manual GX2355S

PROBABLE CAUSE

No DC voltage to the transceiver, or blown fuse.

Reversed power wires.

Engine noise.

External cable

Antenna.

The power supply voltage is too high or too low.

External cable.

Setting of the GPS navigation receiver.

REMEDY

Press and hold the Power switch/ Volume control knob until the transceiver turns on. Check the power cable for DC voltage, or replace the fuse (6A 250V).

Make sure the red wire is connected to the positive battery post and the black wire is connected to the negative. If the fuse still blows, contact your Dealer.

Reroute the DC power cables away from the engine. Add noise suppressor on power cable. Change to resistive spark plug wires and/or add an alternator whine filter.

Check the polarity of the connected external cable.

Have the antenna checked or test the transceiver with another antenna. If the problem persists, contact your Dealer for servicing.

Confirm that the connected power supply voltage is not 24 volts or lower than 9 volts. Confirm that the generator has not malfunctioned.

Check the polarity of the connected external cable. Some GPS use the battery ground line for NMEA connection.

Check the output signal format of the GPS navigation receiver. This radio requires NMEA0183 format with GLL sentence as an output signal. If the GPS has a baud rate setting make sure to select 4800 and parity to NONE

SYMPTOM

Transceiver fails to power up.

Transceiver blows fuse when connected to power supply.

Popping or whining noise from the speaker while engine runs.

Sound is not emitted from the external speaker.

Receiving stations report low transmit power, even with transceiver set to HI power.

“HI BATTERY” or “LOW BATTERY” is displayed when the power is turned on.

Your position is not displayed.

11. CHANNEL ASSIGNMENTS

Tables on the following columns list the VHF Marine Channel assignments for U.S.A., Canada and International use. Below are listed some data about the charts.

1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s Vessel Traffic System.

2. Alpha channel numbers, that is, channel numbers followed by the letter A (such as Channel 07A) are

simplex

channels on the U.S.A. or Canadian channel assignments whose counterparts in the International assignments are

duplex

channels. International channels do not use “alpha” numbers.

If you call the Coast Guard on Channel 16, they will sometimes ask you to

“go to channel 22 Alpha.”

This is a channel assigned to U.S.A, and Canadian Coast Guards for handling distress and other calls. If your radio is set for

International

operation you will go to Channel 22 instead of 22A, and will not be able to communicate with the Coast Guard. To use Channel 22A, your radio must be set for

USA

Canada

operation, usually by a U/ I/C (USA/International/Canada) control or combination of controls. Channel 22 (without an “A”) is an

International

duplex channel for port operations. Some radios indicate an “A” adjacent to the alpha channels on the display; on others “alpha” is not indicated but the proper channel is selected based on the U/I/C setting.

3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge operators on intercoastal waterways and rivers. It is also used by marine vessels in the vicinity of these bridges for navigation and for communicating with the bridge operators.

Note that a limit of 1 Watt is

specified for these channels.

See page 51 for additional information.

4. The

S/D

column on the chart indicates either S (simplex) or D (duplex).

Simplex

means transmitting and receiving on the same frequency. Only

one party at a time can talk, unlike a telephone. Be sure to say

“over”

and release your microphone push-to-talk switch at the end of each transmission.

Duplex

operation involves the use of one frequency for transmitting and a separate frequency for receiving. On channels specified as duplex on the charts, correct mode of operation is established automatically by your radio when you select a channel; you cannot change the mode. And you still must release the push-to-talk switch after each transmission in order to listen to the radio.

5. Channels normally used by recreational boaters are those that include the term “non-commercial” in the

Channel Use

column of the chart. Some of these are shared with other users and some are used only in certain geographic regions. The Marine Radio – Telephone User’s Handbook identifies shared channels in details.

6. Marine vessels equipped with VHF radios are required to monitor

Channel 16.
