then returns to the previous indication AND Functions for receive
D Squelch function The squelch function detects signals with voice components and squelches mutes unwanted signals such as unmodulated beat signals
This provides quiet standby When you need to receive weak signals the squelch should be turned OFF Push F then 2 and OFF
to switch the function ON
F 2 SQL SQL appears when the squelch function is turned ON
See page 48 for the squelch level Noise blanker The noise blanker function reduces pulse type noise such as that coming from engine ignitions etc The
noise blanker may distort reception of strong signals In such cases the noise blanker should be turned OFF Push F then 1 NB to switch the function ON
and OFF
See page 48 for the noise blanker level adjustment F 1 NB NB appears when the NB function is turned ON
D AGC OFF function The receive gain is automatically adjusted according to received signal strength with the AGC Automatic Gain Control function to
prevent distortion from strong signals and to obtain a constant output level When receiving weak signals with adjacent strong signals or noise the AGC
function may reduce the sensitivity In this situation the AGC function should be deactivated Push F then 5 AGC to switch the function ON and OFF
F 5 AGC A G C appears when the AGC function is turned OFF
D RF gain setting The receiver gain can be reduced with the RF gain setting This may help to remove undesired weak signals while monitoring strong
signals Usually the AGC function reduces the RF gain according to the receive signal strength and these weak signals are removed However during no
signal reception these weak signals may not be heard In such cases the RF gain may be useful for setting a minimum level at which to hear signals

If your Icom SSB is going aboard a sailboat you may either use an insulated backstay an insulated sidestay or a nonresonant white fiber glass whip
antenna off the stern to make up your antenna system Your best range will be from an insulated backstay because of the long length of the antenna
radiator which is that portion within the top and bottom insulators Have your rigger put the top insulator about at least 3 feet down from the tip of
the mast Have your rigger install the bottom insulator at about eyelevel when youre standing back aft This length between insulators should not exceed
120 or be less than 23 If you decide to go for the nonresonant whip antenna the antenna usually goes at the extreme stern and mounts either vertically
or raked back at about a 45degree angle These nonresonant antennas may be tuned by the ICOM automatic antenna tuner that matches the Icom SSB
transceiver The tuner goes back aft in the lazarette or as close to the antenna as possible It is completely and can easily take the punishment of
being aft and below deck where youre probably also going to store wet life preservers foul weather gear and the like The tuner interconnects with the
Icom SSB Full details are in the tuner instruction manual We suggest you use GTO15 high voltage leadin wire from the single wire output of the tuner
to your insulated backstay or to your nonresonant whip This high voltage wire wont break down in wet weather or sunlight Use stainless steel hose
clamps to attach the wire to the insulated backstay If you decide to use a nonresonant whip attach the single wire with a lug to the feedpoint at the
base of the whip More about the importance of grounding in a moment For those of you with a powerboat a whip antenna approximately 16 to 20 feet long
is what youll be using with your new Icom SSB The most common setup consists of the white fiber glass nonresonant whip antenna that is automatically
tuned with the ICOM automatic antenna tuner Similar to sailboat the tuner is hidden out of the way in the flying bridge area or below deck near the
base of the whip GTO15 wire interconnects the whip to the automatic tuner The tuner is fed with coax RG 213 and a control line from the back of the
Icom SSB wherever you plan to hide the autotuner Remember the ICOM automatic tuner is fully automatic so you can put it completely out of sight We
suggest you check with the dealer that sold you your transceiver to purchase the ICOM automatic tuner as well as a resonant or nonresonant whip
antenna assembly Dealers that sell ICOM equipment usually have these accessories on This is technically called a and its the absolute necessary
otherhalf of your antenna system that must be achieved for your overall single sideband system to work well Its not that hard to develop your own
sideband RF ground system in just about a days time and you may even find that most of the RF ground system is already installed so you have little to
do but to tie everything together with copper foil Read on please and let us show you how easy it can SPEAKING
If you plan to have a technician or a technical friend install your sideband system have him skip this part and begin reading at Antenna Ground
Principles Technically Speaking If you plan to do the installation yourself and this is the first one youve done read on The water that your boat sits
in is the ultimate ground counterpoise Theres none better Commercial AM broadcast stations on the coast usually put their giant antenna system in the
mud flats of a local bay for good range Some boat suppliers put ground foil and ground screen in the cabin overhead This is true on expensive
powerboats and is sometimes found in a few sailboats While this type of overhead RF ground system is better than nothing it still lacks the capability
of coupling with the ocean or lake as the ultimate water ground system A far better RF ground system would be the following 100 sq ft area of foil
below water line Metal water tanks Lead keel Foil radials throughhull The whole idea is surface area and this is why a keel bolt underwater tanks
and anything else flat and next to the water does such a good job Now we know your next question But doesnt a good ground actually have to be in
contact with the water Not at all At radio frequencies RF your underwater ground counterpoise sees the water in a capacitive way which gives just as
good a ground effect as if it were actually touching the water Now heres another very important point no round wires for RF ground Even if you use
welding wire the size of your thumb you cannot achieve a good ground counterpoise with round wire In our Technically Speaking section well tell you
why but in nontechnical terms round wires tend to cancel out at radio frequencies and they look invisible as a ground counterpoise interconnect This
is why copper foil must be used between the chassis of your transceiver to your ships RF ground as the chassis of the automatic antenna tuner to ships
RF ground Your better marine electronic stores that sell ICOM equipment will also sell threeinch wide superthin copper foil for grounding In a pinch
you can use oneinch wide copper plumber s tape Threeinch is better Note A three inch strip mounted three inches away from another three inch strip of
copper foil looks like a nine inch strip to a radio wave Its going to take you about a day to work this foil below decks and below the water line
picking up anything and 63
13 14
THE IMPORTANCE OF read this If you are looking for super range with your new Icom SSB we have some tricks that will give you the same kind of range
as cruise ships super tankers solo sailors the Navy and the Coast Guard Surface area to the sea water and the use of copper foil exclusively
throughout your RF ground system is the combination that gives you super range The sea water acts like a diving board or side of a pool for a diver
and a swimmer it gives your signal a solid surface to push AND GROUNDING of ground potential If you can get at your keel bolt or tap a screw into
the keel your grounding is done Lead incapsulated keels are the ultimate in grounds and you may need nothing further In powerboats since theres no
keel youre going to need to come up with at least 100 square feet of RF ground surface below the water line This means you must pick up as many ground
potentials below the water line as possible We usually use a stainless steel hose clamp to grab each underwater metal source Now lets take a look at
grounding from a slightly more technical point of view Dont worry we wont get and its easy to read and understand If youre letting a technical friend
of technician put in your equipment make sure they read over this section several times The facts here are based on hundreds of hours of doing and
undoing different types of ground systems In all cases following these techniques will give you the results that you want and thats long range and the
loudest signal on the band
set and may even cause burnouts of tiny integrated circuits in companion marine electronic gear aboard ISOLATING YOUR RF GROUNDING SYSTEM FROM YOUR DC
GROUNDING SYSTEM WILL PREVENT THESE UNWANTED AREA
For marine SSB radios a good radio frequency ground system will consist of a minimum of 100 square feet of metal below the waterline Now we know youre
going to jump out of your chairs when you read this but dont be overwhelmed There are plenty of underwater metals that we might attach to in order to
obtain this amount of counterpoise below the waterline Lead keels incapsulated within fiber glass will make excellent surface area grounds in sailboat
applications The tough part will be getting to the lead keel or the exposed keel bolt In other marine stainless steel tanks copper hydraulic lines
and will help make up the RF ground counterpoise system Boat manufacturers have the capabilities of adding a terrific RF ground system when the hull
is being laid up Lightweight copper screen is one of the best ways to provide a good surface area ground Copper screen could be laminated inside the
fiber glass layers as the hull is under construction Thin sheets of copper foil could also be used in the manufacturing process of the hull Even the
conducting mesh that holds together cement hulls can be used quite nicely as a ground counterpoise system Copper foil and grounding screen is
available from most marine electronic distributors as well as marine electronic dealers Thickness of the screen and foil is not important the most
common foil is generally one to four mills thick and comes in threeinch wide rolls of just about any length you want Copper window screen if you can
find it is usable thickness is not important Radio frequency energy travels on the outside of this conducting surface called skin effect eliminating
the need for thick grounding materials Since grounding foil and screen is relatively expensive most boat builders will simply leave out this grounding
process and expect the customer to provide their own RF ground once the boat is finished This is a shame its so easy to build in when the hull is
under construction and far more difficult to add after the vessel is fully completed The copper foil and screen does not actually need to contact
seawater in order to create the ground system Radio frequency energy passes through fibreglass so an incapsulated ground system works just as well as
one that is actually exposed to the seawater Incapsulated lead keels with a halfinch of resin also work well Any RF ground system that is capacitively
coupled to the seawater is enhanced by the seawater itself Developing the ground system for radio frequency applications as opposed to DC grounding
systems requires that all ground connections be interlaced using copper foil Round ground wires are out Wires actually look like inductive
trapcircuits at certain radio frequencies and will appear invisible as an effective way of coupling your set to your ground system Thats right copper
foil must be run from below the wa
ANTENNA GROUND PRINCIPLES TECHNICALLY SPEAKING
The marine antenna system for low medium and high frequency applications will utilize both the seawater as well as radiator for its entire operation
Like two kids on a the system works well if there is a balance between the antenna radiator and the seawater ground This balanced antenna system may
electrically be compared to a dipole antenna system onehalf wavelength long on the frequency band of operation with voltage and current loops equally
distributed throughout the halfwave length system In marine applications where a vertical antenna is used this system is more precisely referred to as
a Hertz antenna setup The white fiber glass whip is tuned to an electrical onequarter wavelength and the ground system will make up the other
onequarter wavelength We technically call the RF ground system a and the antenna the radiator If either a onequarter wavelength antenna or ground
system is missing or inadequate radio reception and transmission range will be severely reduced How good was your car radio reception when someone
broke off your whip antenna The same degradation of range also takes place when there is little or no RF ground system for antenna to work against in
a marine installation Imagine a swimmer making a flip turn but not having the side of the pool to push off from The same thing happens with radio wave
transmissions on single sideband The most powerful antenna will not radiate a signal if it has not counterpoise to push off the signal from In
technical terms the less RF ground the higher the radiation resistance of the antenna system This radiation resistance will lead to substantial power
loss and single sideband equipment will not only perform poorly but also get quite hot in the transmitter section An inadequate single sideband RF
ground will also lead to hot mikes where the operator actually receives a radio frequency burn each time the mike is held next to his mouth Poor RF
grounding will also lead to erratic movement of analogue dial instruments bizarre behavior of automatic pilots while transmitting on the sideband 64
ANTENNA AND GROUNDING ground system and attached directly to each piece of low and high frequency radio gear While this may also seem to be an
problem in running foil rather than wire foil handles quite nicely even in tight places The foil is easily soldered to the below waterline ground
system and then routed up the side of the hull into the area of the NAV station It may be glassed into the hull painted over glued in or even left
resting on the side of the hull The foil may be bent in order to accomplish a 90degree turn If the foil must absolutely pass through a small hole it
may be rolled up in a notsotight configuration and squeezed through the orifice Avoid a concentric type for that type tends to cancel oscillating
radio frequencies Flat is best There are several sticky marine compounds that will allow the foil to adhere to the underside of a hatch or to the side
of a hull Almost anything will work and there is little danger of any substantial amounts of voltage developing on your ground foil run The ground
foil and your complete RF ground system which run inside the hull also will not substantially change your corrosion exposure to the seawater Galvanic
corrosion problems occur when dissimilar metals are immersed in seawater The ground system is not actually immersed its coupling is only capacitive
Electrolysis is another form of corrosion where stray currents may begin to eat up underwater metals Good wiring techniques for your 12volt system
independent of your RF ground system will eliminate electrolysis Now lets get back to finding a spot to terminate that threeinch wide copper foil that
emanates from the below waterline ground system Most manufacturers of Loran weather fax and marine single sideband sets dont provide an easy way of
adding ground foil to the stern end of their electronics The best method is to run the foil up to the back of the equipment and use existing sheet
metal screws to make a firm connection Where a ground post stud with nuts and a washer are provided all the better run the foil up to the stud double
it back on itself several times for strength punch a hole in it and then make the connection Never negate all your hard work of running the foil by
using a small jumper wire to interconnect the foil to the radio setup You will be putting a weak link in your ground system at radio frequencies We
usually accordion up the excess foil in back of the equipment so that we might remove the equipment for servicing with the foil attached If you put
the bends in the right spot the foil will resume its natural collapsed state when the equipment is put back in place Watch out for the sharp corners
on the ground foil they are capable of piercing through the plastic protective covering on electrical wires Make sure that red and black voltage
carrying wires are not allowed to rub up against the side of the ground foil We usually ground everything with foil at the navigation station This
would include the casing of the wind and speed equipment pilot control box GPS sideband radar VHF and just about everything else that lights up The
more grounding you provide for your central electronics the less problems you will have with stray RF The ground foil must also run to remote tuners
This includes the tuner on your Loran antenna setup as well as the ICOM single sideband tuner thats usually several feet away from the equipment These
tuners may be all the way back aft
adding another dimension to your ground foil run Its best to run the foil from the RF ground source directly to your tuner rather than stringing
everything out in series like Christmas tree lights Now picture one ground foil run from the keel bolt to the electronics and a second ground foil run
from the keel bolt back aft to the sideband tuner and your sternmounted Loran whip These tuner ground circuits are mandatory for any type of reliable
operation If you try to run an ICOM sideband set with a remote tuner that is you stand the chance of not only burning up your equipment but also
damaging other electronics onboard with stray RF If its not easy to run ground foil from your central below the waterline ground source back aft then
try to figure out another way to do it It has to be done You can also pick up additional ground counterpoise surface area by adding substantial metals
along the way in your copper foil run Stainless steel hose clamps make it easy to pick up throughhull bronze fittings water tanks copper hydraulic
lines and anything else that may give you some additional underwater surface area Mariners with sailboats with poured incapsulated lead keels as well
as metal hull vessels have the easiest time in obtaining a good ground counterpoise If the keel is visible a second nut on the exposed thread will
anchor on the ground foil We usually seal this connection to prevent deterioration from the bilge water It may also be recommended by local experts to
tie in the aluminum mast to this close proximity keel bolt for lightning protection The run from the mast to the keel bolt must be smooth direct and
without sharp turns in order to pass lightning energy effectively into the underwater lead Again consult local lightning experts Steelhulled vessels
are easily attached to with foil by scraping away any protective coating from the hull and making a low resistant good surface area contact Again seal
this connection well Nonmetal hull or keel boats require yards and yards of foil to be run below the waterline anywhere you can and picking up any
other large below the waterline tanks and you follow these steps you will have an outstanding single sideband signal that can be heard around the
world The difference between a good and bad ground is easily noticed on transmission as well as reception Since your ground counterpoise is actually a
part of your complete antenna system pay just as much attention to RF grounding as you did to putting up that white fiber glass whip or installing to
your insulated Frequency coverage Receive MHz

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
