5 GETTING STARTED
5.1 PROHIBITED COMMUNICATIONS
The FCC prohibits the following communications:
False distress or emergency messages:
Messages to “any boat” except in emergencies and radio tests;
Messages to or from a vessel on land;
Transmission while on land;
Obscene, indecent, or profane language (potential ne of $10,000).
5.2 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 essen-
tially “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 xed mount 25W radio transmission expected distances can be greater
than 15 miles.
5.3 SELECTING AN ANTENNA
Marine antennas are made to radiate signals equally in all horizontal direc-
tions, 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.
Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast.
The longer 8 foot 6dB berglass whip is primarily used on power boats that
require the additional gain.

GX1600/GX1700

5.4 COAXIAL CABLE
VHF antennas are connected to the transceiver by means of a coaxial cable
– a shielded transmission line. Coaxial cable is specied 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-8X or
RG-213/U should be used for cable runs over 50 feet RG-8X should be used.
For installation of the connector onto the coaxial cable refer to the figure
below.
To get your coax cable through a tting 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.
5.5 EMERGENCY (CHANNEL 16 USE)
Channel 16 is known as the Hail and Distress Channel. An emergency may
be dened 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 proce-
dure:
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 navi-
gation aid or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, re, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance your desire (pumps, medical aid, etc.).
GX1600_GX1700_usa_EM048N161.indd 8 2013/03/13 14:43:41
Page 9
GX1600/GX1700
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.
NOTE
The GX1600 and GX1700 have DSC distress calling, that can trans-
mit a distress call digitally to all ships with compatible DSC radios.
Refer to section “9 DIGITAL SELECTIVE CALLING”.
5.6 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.
Channel 16 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
signicantly in U.S. 0waters by using channel 9 as the initial contact (hailing)
channel for non-emergency communications. Also hailing on channel 9, the
calling time should not exceed 30 seconds but may be repeated 3 times at
2-minute intervals.
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 trafc, and then go back to either channel 16 or 9 for your initial contact.
When the hailing channel (16 or 9) is clear, press the PTT button on the mic
and 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)
then release the PTT button on the mic. When the other vessel returns your
call, immediately request another channel by pressing the PTT button on
GX1600_GX1700_usa_EM048N161.indd 9 2013/03/13 14:43:41
GX1600/GX1700
Page 10
the mic and saying “go to,” the number of the other channel, say “over” and
release the PTT button on the mic. 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-to-talk
(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.
5.7 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose.
Check with your local marina to learn which channels are used for radio-
telephone trafc. Channels available for such trafc are designated Public
Correspondence channels on the channel charts in this manual. Some
examples for USA use are the 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 tele-
phone 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.
5.8 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks, 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 trafc 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 26 (
key) for means to temporarily over-
ride the low-power limit on these two channels.
5.9 AUTOMATED RADIO CHECK SERVICE
In areas across the country, Sea Tow offers boaters a way to conduct radio
checks. To use Sea Tow’s free Automated Radio Check service, simply tune
GX1600_GX1700_usa_EM048N161.indd 10 2013/03/13 14:43:41
Page 11
GX1600/GX1700
your VHF radio to the appropriate channel for your location and conduct a
radio check as you typically would. Upon releasing your radio’s microphone,
the system will play an automated message and relay your transmission back
to you, thereby letting you know how your signal will sound to other boaters.
The Automated Radio Check Service is currently available in the areas listed
below.

9 DIGITAL SELECTIVE CALLING
9.1 GENERAL
WARNING
The GX1600 and GX1700 are designed to generate digital mari-
time distress and safety calls to facilitate search and rescue. To
be effective as a safety device, this equipment must be used only
within communication range of a shore-based VHF marine channel
70 distress and safety watch system. The range of signal may vary,
however under normal conditions should be approximately 20 nauti-
cal miles.
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 as part of the Global Maritime Distress and Safety
System (GMDSS).
Digital Selective Calling allows 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, Routine, Position Request, Posi-
tion Report, Automatic Position Polling and Group calls to or from another
vessel equipped with a DSC transceiver.
NOTE
A DSC Warning sticker is included with the
GX1600 and GX1700. To comply with FCC regu-
lations this sticker must be mounted in a location
that can be easily viewed from the location of the
GX1600 and GX1700.

9.2 MARITIME MOBILE SERVICE IDENTITY (MMSI)
9.2.1 What is an MMSI?
An 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.
THIS NUMBER MUST BE PROGRAMMED INTO THE RADIO TO OPER-
ATE DSC FUNCTIONS.

9.4 ALL SHIPS CALL
The all ships call function allows contact to be established with DSC
equipped vessels without having their MMSI in the individual calling direc-
tory. Also, priority for the call can be designated as “Urgency” or “Safety”.
URGENCY Call: This type of call is used when a vessel may not truly be
in distress, but has a potential problem that may lead to a
distress situation. This call is the same as saying “PAN PAN,
PAN PAN, PAN PAN” on Channel 16.
SAFETY Call: This type of call is used to transmit boating safety informa-
tion to other vessels. This message usually contains infor-
mation about an overdue boat, debris in the water, loss of a
navigation aid or an important meteorological message. This
call is the same as saying “Securite, Securite, Securite.”

9.6 GROUP CALL
This feature allows the user to contact a group of specic vessels (example
members of a yacht club) using DSC radios with group call function to auto-
matically switch to a desired channel for voice communications. This func-
tion is very useful for yacht clubs and vessels traveling together that want
to collectively make announcements on a predetermined channel. Up to 32
group MMSI may be programmed.
9.6.1 Setting up the Group Call
For this function to operate, the same group MMSI must be programmed
into all the DSC VHF radios within the group of vessels that will be using this
feature. To understand group MMSI programming, rst a ship MMSI has to
be understood.
Ship MMSI: The rst three digits called a MID (Mobile Identity Group) of a
ship MMSI denote the country the ship registered for a MMSI. The last 6
digits are specic to the ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which
denote the country and “123456” is your ships MMSI.
Group MMSI:
Group MMSI numbers are not assigned by the FCC or other organiza-
tions licensed to assign ship MMSI numbers.
The rst digit of a group MMSI is always set to “0” by the international
rules. All Standard Horizon radios are preset so when programming a
group MMSI the rst digit is set to “0”.
The USCG recommends programming the MID of a ships MMSI into the
second, third and fourth digits of the group MMSI as it denotes the area
the ship is located in.
The last 5 digits are decided upon by persons in the group. This is an
important step as all radios in the group must contain the same group
MMSI so they can be contacted by each other. There is a chance that
another group of vessels may program in the same group MMSI. If this
happens, simply change one or more of the last 5 digits of the group
MMSI.

9.7 POSITION REQUEST
Advancements in DSC have made it possible to poll the location of another
vessel and show the position of that vessel on the display of the GX1600
and GX1700. Standard Horizon has taken this feature one step further, if any
compatible GPS chart plotter is connected to the GX1600 and GX1700, the
polled position of the vessel is shown on the display of the GPS chart plot-
ter making it easy to navigate to the location of the polled vessel. This is a
great feature for anyone wanting to know the position of another vessel. For
example your buddy that is catching sh, or nding the location of a person
you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected
to its DSC radio and must not have its radio set to deny position
requests. (Refer the section “9.5 INDIVIDUAL CALL” to enter infor-
mation into the individual directory).
9.7.1 Setting up the Position Reply
The GX1600 and GX1700 can be setup to automatically (default setting) or
manually send your position when requested by another vessel. This selec-
tion is important if you are concerned about someone polling the position of
your vessel that you may not want to. In the manual mode you will see the
MMSI or persons name shown on the display allowing you to choose to send
your position to the requesting vessel.

9.8 POSITION REPORT
The feature is similar to the position request, however instead of requesting
a position of another vessel this function allows you to send your position to
another vessel. Your vessel must mark the connected GPS receiver for the
GX1600 and the internal GPS receiver for the GX1700 to send the position.
NOTE
To transmit a position report call, a GPS must be connected to the
radio and the individual directory of the GX1600 and GX1700 must
be programmed with stations you wish to send your position to. To
setup this directory refer to section “9.5.1 Individual / Position Call
Directory Setup.”

17 CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments
for U.S.A. 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 Trafc 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 assign-
ments 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 or 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 inter-coastal 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
specied for these channels.
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 speci-
ed 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
