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, for a portable 5W radio transmission the expected distance
canbegreaterthan5milesin“lineofsight”.
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.

Page 8 GX2000/GX2150
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 DISTRESS AND HAILING (CHANNEL 16)
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.).

NOTE
The GX2000 and GX2150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 (DSC)”.
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.
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.Call-
ingshouldnotexceed30seconds,butmayberepeated3timesat2-minute
intervals.Inareasofheavyradiotrafc,congestiononchannel16resulting
fromitsuseasahailingchannelcanbereducedsignicantly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inter-
rupting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

Page 10 GX2000/GX2150
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.
Thefastestwaytolearnwhichchannelsareusedforradiotelephonetrafc
istoaskatalocalmarina.Channelsavailableforsuchtrafc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 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 BRIDGE 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29(
H / L
key)formeanstotemporarily
overridethelow-powerlimitonthesetwochannels.

5.10 WHAT IS THE RANGE FOR AIS RECEIVERS?
SinceAIS uses similar frequencies as a marine VHF radio, it has similar
radio reception capabilities - which are basically line of sight.This means
thatthehighertheVHFantennaismounted,thegreaterthereceptionarea
willbe.ReceptionfromClassAvesselsthatare20oreven30milesaway
on open water is not uncommon as their antennas are mounted high off the
water. Class B transponders use lower power for transmissions; therefore
youcanexpectClassBvesselstobeacquiredwhentheyare5to10miles
away.
NOTE
TheMATRIXAIS+ GX2150 does not require aspecialmarineVHF
antenna to receiveAIS transmissions. The MATRIXAIS+ does not
transmitAISsignals,itisNOT recommendedtouse anantenna
dedicatedforAISoperation.
