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 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”.
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 st ainless 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
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 RG213/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 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 reading 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 desired 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.
8.2 ELECTRICAL CONNECTIONS
CAUTION
Reverse polarity connections will damage the radio!

10.7.1 NOAA Weather Alert
In the event of extreme weather disturbances, such as storms and hurricanes,
the NOAA (National Oceanic and Atmospheric Administration) sends a weather
alert accompanied by a 1050 Hz tone and subsequent weather report on one
of the NOAA weather channels. When the Weather Alert feature is enabled
(see section “12.10 WEATHER ALERT (ON/OFF)”), the transceiver is capable
of receiving this alert if the following is performed:
1. Program NOAA weather channels into the transceiver’s memory for scanning. Follow the same procedure as for regular channels under section
“10.13.2 Memory Scanning (M-SCAN).”
2. Press the [SCAN] key once to start memory scanning.
3. The programmed NOAA weather channels will be scanned along with the
regular-programmed channels. However, scanning will not stop on a normal weather broadcast unless a NOAA alert is received.
4. When an alert is received on a NOAA weather channel, scanning will stop
and the transceiver will emit a loud beep to alert the user of a NOAA broadcast.
5. Press the [WX] key to stop the alert tone and receive the weather report.
NOTE
If the [WX] key is not pressed the alert tone will be emitted for 5 minutes
and then the weather report will be received.

the GX5500S’s NOAA Weather feature, on Wednesday between 11AM and
1PM, setup as in section “10.7.1 NOAA Weather Alert” and confirm the alert is
heard.
GX5500SPage 26
10.8 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, May-
day. 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.
)
10.9 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.
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
)
Page 27GX5500S
traffic, and then go back to either channel 16 or 9 for your initial contact.
When the hailing channel (16 or 9) is clear, st ate 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-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.
10.10 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 Pub-
lic 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.
10.11 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] key) for means to temporarily override the
low-power limit on these two channels.
