GX3000SPage 87  GETTING STARTED7.1  ABOUT VHF RADIOThe radio frequencies used in the VHF marine band lie between 156 and 158MHz 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 mount25W radio transmission expected distances can be greater than 15 miles.7.2  SELECTING AN ANTENNAMarine 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 signaltoward the horizon. The degree to which this is accomplished is called theantenna’s gain. It is measured in decibels (dB) and is one of the major factorsin choosing an antenna. In terms of effective radiated power (ERP), antennasare rated on the basis of how much gain they have over a theoretical antennawith zero gain. A 3 foot, 3dB gain antenna represents twice as much gain overthe imaginary antenna.Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. Thelonger 8 foot 6dB fiberglass whip is primarily used on power boats that requirethe additional gain.FCC ID: K6630143X3D/IC ID: 511B-30143X3DVertex Standard Co., Ltd.
Page 9GX3000S7.3  COAXIAL CABLEVHF antennas are connected to the transceiver by means of a coaxial cable –a shielded transmission line. Coaxial cable is specified by it’s diameter andconstruction.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 forcable runs over 50 feet RG213 should be used. For installation of the connectoronto the coaxial cable refer to the figure below.To get your coax cable through a fitting and into your boat’s interior, youmay have to cut off the end plug and reattach it later. You can do this ifyou follow the directions that come with the connector. Be sure to makegood soldered connections.1/16''3/4''3/4''1 1/8''1/8''5/8''3/8''AdapterFCC ID: K6630143X3D/IC ID: 511B-30143X3DVertex Standard Co., Ltd.

Page 27GX3000S10.8  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 messages. This channelmust 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. Callingshould 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 itsuse as a hailing channel can be reduced significantly in U.S. waters by usingchannel 9 as the initial contact (hailing) channel for non-emergency communi-cations. Here, also, calling time should not exceed 30 seconds but may berepeated 3 times at 2-minute intervals.Prior to making contact with another vessel, refer to the channel charts in thismanual, and select an appropriate channel for communications after initial con-tact. For example, Channels 68 and 69 are some of the channels available tonon-commercial (recreational) boaters. Monitor your desired channel in advanceto make sure you will not be interrupting other traffic, and then go back to eitherchannel 16 or 9 for your initial contact.When the hailing channel (16 or 9) is clear, state the name of the other vesselyou wish to call and then “this is” followed by the name of your vessel and yourStation 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 notbusy, 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, endthe last transmission by stating your Call Sign and the word “out.” Note that it isnot 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. Someradios automatically monitor Channel 16 even when set to other channels orwhen scanning.10.9  MAKING TELEPHONE CALLSTo make a radiotelephone call, use a channel designated for this purpose, Thefastest way to learn which channels are used for radiotelephone traffic is to askat a local marina. Channels available for such traffic are designated PublicCorrespondence channels on the channel charts in this manual. Some ex-amples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87.

Page 35GX3000S11  DIGITAL SELECTIVE CALLING11.1  GENERALWARNINGThis radio is designed to generate a digital maritime distress and safetycall 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. Therange of signal may vary but under normal conditions should be approxi-mately 20 nautical miles.NOTEA DSC Warning sticker is includedwith the GX3000S. To comply withFCC regulations this sticker must bemounted in a location that can be eas-ily viewed from the location of theGX3000S. 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 radiocall, it has been designated by the International Maritime Organization (IMO)as an international standard for establishing VHF, MF, and HF radio calls. It hasalso been designated as part of the Global Maritime Distress and Safety Sys-tem (GMDSS). It is planned that DSC will eventually replace aural watches ondistress frequencies and will be used to announce routine and urgent maritimesafety information broadcasts.This new system allows mariners to instantly send a distress call with GPS posi-tion (when connected to the transceiver) to the Coast Guard and other vesselswithin range of the transmission. DSC will also allow mariners to initiate or receiveDistress, Urgency, Safety, Routine, POSITION REQUEST, POSITION SEND, andGroup calls to or from another vessel equipped with a DSC transceiver.DISTRESSPULL OPENWARNINGSTICKERFCC ID: K6630143X3D/IC ID: 511B-30143X3DVertex Standard Co., Ltd.

GX3000SPage 8616  CHANNEL ASSIGNMENTSTables on the following columns list the VHF Marine Channel assignments forU.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’sVessel 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 Canadianchannel assignments whose counterparts in the International assignmentsare duplex channels. International channels do not use “alpha” numbers. Ifyou 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 setfor International operation you will go to Channel 22 instead of 22A, andwill 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 basedon the U/I/C setting.3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridgeoperators on intercoastal waterways and rivers. It is also used by marinevessels 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 forthese 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. Onlyone party at a time can talk, unlike a telephone. Be sure to say “over” andrelease your microphone push-to-talk switch at the end of each transmis-sion. Duplex operation involves the use of one frequency for transmittingand a separate frequency for receiving. On channels specified as duplexon the charts, correct mode of operation is established automatically byyour radio when you select a channel; you cannot change the mode. Andyou still must release the push-to-talk switch after each transmission inorder to listen to the radio.5. Channels normally used by recreational boaters are those that include theterm “non-commercial” in the Channel Use column of the chart. Some ofthese are shared with other users and some are used only in certain geo-graphic regions.FCC ID: K6630143X3D/IC ID: 511B-30143X3DVertex Standard Co., Ltd.
