7 GETTING STARTED
7.1 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 ma-
rine 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.
7.2 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.
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.

7.3 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 con-
struction.
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 should be used for
cable runs over 50 feet RG213 should be used. For installation of the connector
onto the coaxial cable refer to the figure below.
Adapter
1/16''
3/4''
3/4''
1 1/8''
1/8''
3/8'' 5/8''
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.

8 INSTALLATION
8.1 LOCATION
The radio can be mounted at any angle. Choose a mounting location that:
• is far enough from any compass to avoid any deviation in compass read-
ing due to the speaker magnet
• provides accessibility to the front panel controls
• allows connection to a power source and an antenna
• has nearby space for installation of a microphone hanger
• the antenna must be mounted at least 3 feet from radio
Note: To insure the radio does not affect the compass or radios performance is
not affected by the antenna location, temporarily connect the radio in the de-
sired location and:
a. Examine the compass to see if the radio causes any deviation
b. Connect the antenna and key the radio. Check to ensure the radio is
operating correctly by requesting a radio check.

10.8 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 and distress 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 inter-
vals. 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 communi-
cations. Here, also, 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 con-
tact. For example, Channels 68 and 69 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, immedi-
ately request another channel by saying “go to,” the number of the other chan-
nel, 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-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 begin-
ning 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.
10.9 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 ex-
GX3000S
Page 27
Download from Www.Somanuals.com. All Manuals Search And Download.
amples 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.
10.10 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 20 ( H/L NAV key) for means to temporarily override the
(
)]
low-power limit on these two channels.
(
)
10.11 DUAL WATCH TO PRIORITY CHANNEL
Dual watch allows the radio to monitor one channel and the assigned Priority
channel. By default the priority channel is set to 16, however the priority chan-
nel may be changed by referring to section “12.6 PRIORITY CHANNEL SET.”
1. Adjust the SQL knob until the background noise disappears.
2. Select the channel you wish to dual watch to “Priority channel.”
[
3. Press the DW IC key.
(
)]
The display will scan between Priority channel and
the channel that was selected in step 2.
If a transmission is received on the channel selected
in step 2, the GX3000S will dual watch between the working channel and
the Priority channel.

11 DIGITAL SELECTIVE CALLING
11.1 GENERAL
WARNING
This radio is designed to generate a digital maritime distress and safety
call 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 but under normal conditions should be approxi-
mately 20 nautical miles.
NOTE
A DSC Warning sticker is included
with the GX3000S. To comply with
WARNING
STICKER
FCC regulations this sticker must be
mounted in a location that can be eas-

ily viewed from the location of the
GX3000S. Make sure the chosen lo-
cation is clean and dry before apply-
ing the sticker.
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 Sys-
tem (GMDSS). 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 system allows mariners to instantly send a distress call with GPS position
(when connected to the transceiver) to the Coast Guard and other vessels within
range of the transmission. DSC will also allow mariners to initiate or receive Dis-
tress, Urgency, Safety, Routine, POSITION REQUEST, POSITION SEND, and
Group calls to or from another vessel equipped with a DSC transceiver.

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 GX3000S.
Standard Horizon has taken this feature one step further, if any Standard Hori-
zon GPS is connected to the GX3000S, the polled position of the vessel is
shown on the display of the GPS chart plotter 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 fish, or
finding the location of a person you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to its
DSC transceiver and must not have its transceiver set to deny position

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 Cana-
dian 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 intercoastal waterways and rivers. It is also used by marine
vessels in the vicinity of these bridges for navigation and for communicat-
ing with the bridge operators. Note that a limit of 1 Watt is specified for
these channels. See page 28 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 transmis-
sion. 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 geo-
graphic regions.

pair is needed. After the repair, a 90-day warranty will be in effect from
the date of return of the unit to the Owner.
This service program is not available for equipment which has failed as a
