6 GETTING STARTED
6.1 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 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 xed mount 25 W radio
transmission expected distances can be greater than 25 km, for a portable 5 W
radio transmission the expected distance can be greater than 8 km in “line of sight”.
6.2 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 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 1 m, 3 dB gain antenna represents twice as much gain over
the imaginary antenna.
Typically, a 1 m 3 dB gain stainless steel whip is used on a sailboat mast. The
longer 2.5 m 6 dB berglass whip is primarily used on power boats that require
the additional gain.
3dB
6dB
9dB
6.3 COAXIAL CABLE
VHF antennas are connected to the transceiver by means of a coaxial cable
– a shielded transmission line. Coaxial cable is specied by its diameter and
construction.
For runs less than 20 feet (6 m), RG-58/U (about 0.25" (6 mm) in diameter),
is a good choice. For runs over 20 feet (6 m) but less than 50 feet (15 m), the
larger RG-8X or RG-213/U should be used. For cable runs over 50 feet (15 m)
RG-8X should be used. For installation of the connector onto the coaxial cable
refer to the gure.
6
To get the coax cable through a tting and into the boat’s interior, you
may have to cut the end plug off and reattach it later. Follow the directions that come with the connector to attach it. Be sure to make good
soldered connections.
6.4 DISTRESS AND HAILING (CHANNEL 16)
Channel 16 is known as the Hail and Distress Channel. An emergency may be
dened 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

6.5 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 trafc, congestion on channel 16 resulting
from its use as a hailing channel can be reduced signicantly 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.
Prior to contacting 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 the desired
channel in advance to make sure you will not be interrupting other trafc, and
then go back to either channel 16 or 9 to make initial contact.
When the hailing channel (16 or 9) is clear, press the PTT switch 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 switch on the mic. When the other vessel returns your call, immediately
request another channel by pressing the PTT switch on the mic and saying “go
to,” the number of the other channel, say “over” and release the PTT switch 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.
6.6 Accuracy of COG
The error in the COG (the path of the antenna position over ground) due to the
actual ship’s speed over ground shall not exceed the following values:
Speed range (knots) Accuracy of COG output to user
0 to ≤1 knot Unreliable or not available
>1 to ≤17 knots ±3°
>17 knots ±1°

11 DIGITAL SELECTIVE CALLING (DSC)
11.1 GENERAL
WARNING
This GX1850/GX1800 series 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 approximately 20 nautical miles.
Digital Selective Calling (DSC) 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). 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 its own position,
to the 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, Position Report, Automatic Position Polling, and Group calls
to or from another vessel equipped with a DSC transceiver.
11.2 DISTRESS ALERT
The GX1850/GX1800 series is capable of transmitting and receiving DSC
distress messages. Distress alerts transmitted from the transceiver include
the latitude and longitude of the vessel when valid GPS position data is being
received.
11.2.1 Transmitting a Distress Alert
NOTE
To be able to transmit a DSC distress alert, the MMSI number must
be programmed, refer to section “8.6.1 Maritime Mobile Service
Identity (MMSI)”.
In order for the ships location to be transmitted, the GX1850/GX1800
series must receive valid position data from the internal GPS receiver
or another GPS device connected with a NMEA 0183 or NEMA 2000
network. Refer to section “8.5.2 Accessory Cables”.
38
Basic Operation

2. When the distress signal is sent, the transceiver
watches for a transmission on CH70 until an acknowledgment signal (distress acknowledgement) is
received.
3. If no acknowledgment is received, the distress alert
is repeated in 4-minute intervals until an acknowledgment is received.
4. When a distress acknowledgment is received, a
distress alarm sounds and Channel 16 is automatically selected. The display shows the MMSI of the
ship responding to your distress.
5. Press the microphone PTT switch and state your name, vessel name,
number of persons on board and the distress situation, then say “over”
and wait for a reply from the acknowledging ship.
6. To turn the distress alarm OFF before the radio retransmits the distress
alert, press the [16/S] key or the [QUIT] soft key.

11.5 GROUP CALL
This feature allows users to automatically contact a specic group of vessels
using DSC radios with the group call function. The called radios can automatically switch to the desired channel for voice communications. This function is
very useful for yacht clubs and vessels traveling together that want to make
communal announcements on a predetermined channel. Up to 32 group MMSIs
may be programmed.
11.5.1 Setting up a Group Call
For this function to operate, the same group MMSI (Maritime Mobile Service
Identity Number) 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 MID (Mobile Identity Group) of a ship
MMSI denote the country where the ship’s MMSI is registered. The last 6 digits
are specic to the ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which denote
the country and “123456” is the vessel’s MMSI.
Group MMSI:
Group MMSI numbers are not assigned by the FCC or other organizations
licensed to assign ship MMSI numbers.
The rst digit of a group MMSI is always set to “0” by International rules. All
Standard Horizon radios are preset so when programming a group MMSI
the rst digit is set to “0”.
The ITU (International Telecommunication Union) recommends program-
ming the MID of a ship MMSI into the Second, Third and Fourth digits of
the group MMSI as it denotes the area where the ship is located.
50
The last 5 digits are decided upon by persons in the group. This is an impor-
tant step as all radios in the group must contain the same group MMSI in
order to be contacted by each other. There is a chance that another group of
vessels may program the same group MMSI. If this happens, simply change
one or more of the last 5 digits of the group MMSI.

compatible GPS chart plotter is connected to the GX1850/GX1800 series, 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,
nd where your buddy is catching sh or nd the location of a vessel you are
cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to
its DSC radio, and the radio must not be set to deny position requests.
(Refer the section “11.4 INDIVIDUAL CALL” to enter information into
the individual directory).

• Data output will be performed according to the data acquisition priority order setting of “ORDER OF PRIORITY”. Refer to section “18.1
ORDER OF PRIORITY (GX1850 series only)” for details.
• When “UNIT POWER” of “OPTION GPS UNIT” is set to OFF, NMEA sentences will not be output. (OPTION GPS reception data will be output as is.)
• The output interval of each NMEA sentence depends on the output
timing on the input device. However, sentences which include POS
data will be output at intervals of two seconds or less.
• When all sentences are set to be output, depending on the baud rate,
not all sentences can be output at intervals of one second or less. GSA
and GSV sentences will be output at intervals of around ve seconds.
