Default How many beer boxes needed to navigate an ocean?

A magnet compass pointing at a lighthouse?? Perhaps if the lighthouse
is coincidentally due magnetic north.

okay, jeffies. you are trying to tell us you really do know something

about
RDF.

so let's call your bluff.

Tell us -- if you can -- just RDF equipment pointing at some radio tower

many
miles away is different from a magnetic compass pointing at some

lighthouse a
mile away.

Address -- if you can -- the difference in accuracy (be specific as to

degree
of uncertainty) between close at hand visional sighting and far away
auditory/cheap volt meter fixing, each system using much the same

mechanical
measuring tools.

we will wait for your explanation, jeffies. particualary that "two

degrees"
stuff.

jeffies, it never ceases to amaze me how ignorant you are AND how you

can't
even seem to realize it.

So with one RDF signal, and a chart, you have a "Line Of Position" or

LOP.
Add
in any other piece of information, like a depth contour, and you have a

Fix.
Its called "piloting," jaxie, you should learn how to do it some time.

Clearly, if you had learned a few basics like this you would not have

been
tempted to "turn back" at Hatteras even though you had a boat full of
electronics.

obviously, jeffies, you don't understand English. try again.

RDF tell from direction the signal came from. That is all.

And it doesn't do it all that well.

now, TRY AGAIN, and don't be so stupid this time.

RDF tells you where -- and ONLY where -- a particular signal came

from.

Sorry jax, I guess you don't know how it works. The chart or book

tells
you
where it comes from. The RDF tells you where that is relative to a

boat.
Its
called an "LOP." They'll tell you about it in the Power Squadron

course
