8 Introduction from Gordon WestWelcome to the world of long distance communications with marinetime You cannot talk to a group of individuals An SSB gives marinersthe ability to share information with one another about weather portsfor years However only recently have we seen the introduction oflowcost nocrystal marine SSB equipment that can offer marineradio ham radio and marine email capabilities in one neat 12voltradio equipment presents the overview of the marine single an review of equipment and suggestedwhat makes SSB radio work on the inside However one thing is forIn this book well show you how in a nontechnical language We will also give you some proven installation techcdealer is an expert in this field They have the experience to complete amarine service and the amateur radio service Well even show youhow to tune in weather facsimile and Do you want to pick up that microphone and a quick phone call home Want to send a FAX or email Ready toonICOM presents the very best in

review the hard working marine VHF radio systemICOMs lCM59 VHF set is shown with optional flush mount kitRadio rules require that you must have a marine VHF radio in yourvessel before you can install a marine SSB transceiverThe international marine VHF service is designed for coastal cruisingWe use marine VHF when we are within 20 miles of a shore stationor another VHF equipped vessel This is the effective range of theVHF receiverThe VHF system is worldwide Whether you cruise toHawaii Bermuda or the Mediterranean the VHFFM channels are theradio The frequencies assigned to channels may be different in theYour typical shiptoshore VHF range to the Coast Guard should beabout 20 miles You can normally hear weather broadcast stationsWX1 WX2 and others up to 80 miles away The marine WXchannels are available only in the US and Canada The range to aIf you are not achieving this minimum range check out your VHFantenna system and all connections For sailboats the best type ofand transmit further than any other type of antenna system Theseantenna are only 3 tall and have 3dB gain They use the height ofthe mast head to achieve maximum rangeFor powerboats you should use a minimum of an 8foot 6dBantenna If you have a large more stable vessel you might want toselect a 21foot 9dB gain antenna that performs well in all but heavyseas A good powerboat antenna installation will normally let you reachA good quality hightech VHF transceiver is also important to marine VHF transceivers These installed radios with optionsmeet minimum digital selective calling DSCnew system for making distress calls This system will be over the next several years Deep Draft over 300 tonsvessels put into service since 1992 comply with this system now Allsels will need DSC VHF radios to communicate with DSC equippedships It is expected that all new marine VHF radios approved for salein the US will be DSC equipped by 20012002 An ICOM DSC in case of an emergency The DSC radio will transmitan emergency call that includes your vessels position taken from theGPS See the wide variety of ICOM VHF sets at your favorite dealerYou must have a VHF set on board and a current FCC ship VHF

squarefeet to achieve consider the following large surface RF ground steel tuna and shaftChain lead keelEngine blockYou can develop your own large surface area RF ground plane into your hull copper screen or 23copper foil to create a good capacity ground plane below the waterline You will be running copper foil inside your hull for a to the seawater No the foil does not go on the outside of thehull The fact that the ground foil is close to the seawater makes all thedifference on transmit and receive range While it might be an effort toget all this foil below the water line it will really make the differencewhen you press down on your microphone keyDid You KnowYour bonding of underwater metals that are already tied inwith a common ground wire will not affect your corrosionall bonded together you may wish to lay out a RF groundsystem to the seawater but thats not really necessaryThese other copper foil leads go directly to the antenna tuner The tunerwill have a ground terminal to

attaching to throughhulls remember it will improve performanceare the best way to pick up these underwater metals Water tanksI know I know trying to get a good RF ground counterpoiseis a bit if you cant get at your keel bolt If this isthe case then drill into the keel and pull up some lead Any sailboatsystem that doesnt use a poured keel is losing a tremendous amount ofpotential in obtaining a

keel by all means use it in your RF ground planefoil and screen below decksGood RF grounding counterpoiseRF grounding all have a common denominatora large amount ofsurface area below the water lineis

achieve the ultimate in long skywave range you need an antennaantenna tuner The longer the antenna the betterFor powerboats your antenna will be a 2 or 3piece fiberglass whipThe fiberglass whip on a powerboat is mounted on the port orwire GTO15 that connects the whip to the nearby automatic antennatuner This whip is sufficient for most powerboatsAn insulated backstay is the most popular choice

memoryALL THOSE CHANNELS Marine SSB frequencies are back down to earth at different angles 2 and 4 MHz come day and night skywave skip contacts On 16 and 22MHz skywaves fade out at night but offer the longest range during dayThe best range usually follows the direction of the sunChoose the megahertz range that will skip your signal to thefavorites during the day and 4 and 6 MHz are the favorite bandsduring the night 2 MHz is clobbered with noise and you wont get zip22 MHz is too high for reliable daily contacts Choose 8 and 12 Union and assigns commonalityBut there are differences between each manufacturer of SSB equipmenton how they read out the channels so stay tuned More to followMost 2 MHz frequencies have little use even 2182 MHz the and calling frequency The range is so limited
