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.

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

Sorry Jaxie, I'm not playing your game. I'm sure you stayed up all night
reading up on this, while I haven't used RDF in about 20 years. And what bluff
are your calling? Everything I knew about RDF came from the Ray-Jeff manual,
maybe 8 pages.

The simple fact is that RDF was the common way for near-shore cruisers to
navigate 30-40 years ago. Thousands of Ray-Jeff and Benmar RDF units were sold,
and almost any boat that ventured out in the fog had one. When you cruised a
region that has more than a 50% chance of fog daily it would be crazy not to.

You're right that RDF is not as accurate as GPS, and that there are a variety of
errors possible, espcially at sunrise, sunset, periods of sunspots, etc. And
comercial stations with inland towers could be misleading from "shoreline
affect." I'm sure you've googled up a whole list of problems, especially those
of concern to aircraft that need longer range navigation. (I'm sure that's what
going on here - you learned that simple RDF is not good for long range aircraft
nav, you then assume it can't work for small boats.)

However, in practice it was not necessary to worry about this. When you're
crossing the Gulf of Maine planning a landfall at Criehaven, it was reassuring
to hear the beacon on Matinicus (two miles away). The error is meaningless,
since it goes away as you approach. (And you can feel the foghorn if you get
within a mile!) RDF wasn't used much for narrow channels or other close in
work; it was used for approaches from offshore, where there is no other
reference.

So what's your alternative, jaxie? You've claimed many times dead reckoning is
worthless. On an overnight crossing you could easily find a DR uncertainty of
20 miles, more if the helm was sloppy. An RDF fix could reduce the uncertainty
to 5 miles or less. Or it could give you a target to home in on. So what would
you do? I think you would turn back!

BTW, from the latest Bowditch: "In general, good radio bearings should not be in
error by more than two or three degrees for distances under 150 nautical miles."
As I've said, I didn't expect it to be that good, and the way we used it it
didn't matter if it was much worse.

Jax,

I one of your replies, when you were incorrect but close enough, you
made a big thing of concepts. How about in Navi.?

You talk of cardboard "Astrolobes" and being within 60 miles. I can be
within 15 miles just using my fist and watch set to GMT. The Concept
isn't hard; Think about it.

The year is composed of 4 seasons. 365/4 plus 6 hours a year until Leap
Year. That is the time it takes the Earth to go around the Sun. Each
season in determined by the slant of the Earth as compared to the Sun (
If you look on any large scale chart, you will find two lines above and
below the Equator The Tropic of Cancer and the Tropic of Capricorn) They
are found at 221/2 North and 221/2 degrees South. That is the Slant of
the Earth:

Each Season is 91 1/4 divided by 22 1/2=4.05 days per degree. The
average days for a one deg change of sun angle. Since the change is in
the form of a sine wave, we can brake that average down an awful lot by
using RMS average for the observed change at the top of the sine wave.
Roughly the top 29% and 70.7% for the bottom. That my Mensa friend is
basically the Sun Sight Tables

How do you make the angle on the sun;

You make a Fist with your thumb stuck under your fingers to the first
knuckle and extend it at arms length. The fist will be 10 degrees. Each
knuckle to knuckle is 2 degrees, The top of the knuckle to the valley
between the knuckles is 1 degree, half way up the knuckle is a 1/2
degree, the distance in between is 1/4 degree
Now if you use your cap you can shade out the sun until you can detect
just the bottom of the sun. This distance can be measured with fists and
knuckles to the Horizon. ( don't forget to allow for your own height
above) That is your Observed LATITUDE

Longitude; The Earth rotates 360 degrees every 24 hours: 360/24=15
degrees every hour. Zero starts a GMT, Midnigth at International Date
line (180 degrees) Local Noon is when the Sun observed at its highest
(Fist and knuckles)

A CONCEPT that will let you know pretty damn close any where you are in
the world

Thom, your theory is correct, but I doubt you'd get that accuracy for latitude
unless you spent a lot of time calibrating your knuckles. And determining the
time of local noon is virtually impossible because the Sun "hangs" at noon for a
minute or so. Even with a sextant you wouldn't come within 30 miles of your
position. You might be able to make a better guess with sights an hour before
and after noon, but not with your knuckles.

And one fundamental mistake, Jax didn't talk about a paper astrolabe, he lifted
that directly from the "Latitude 38" web site. Jax can't find his position to
15 miles with a GPS.

BTW, I have a "paper sextant" and a tiny booklet with tables that would allow
pretty accurate navigate, at least compared to "knuckle sights." Its called
"Particularized Navigation" by Frances Wright.

In the days when we were all making use of RDF (either for a fix or a

Jeff,

The Noon sight would still have to be averaged as with a sextant. I
thought I took enough time.

About checking your fist and knuckles. It is done very easy. Stand in
the corner of a room, extend your fist and check how many fist it takes
to get 90 Degrees. (Two walls)

Give it a try. Its fun. Also telling time. A good estimate of time to
sunset. When the wind stops give you something to do. When your becalmed
the mast give a pretty good vertical reference point.

thought the "rocks" at Hatteras were so scary you wanted to turn back, you
have
no business cruising where there are real rocks!

BOO!

How many beer boxes needed to navigate an ocean?
 

an *this* was accurate to what??

2 degrees? 5 degrees? what the hell knows how many degrees?

dude, wandering around in unknown waters with a obstacles nearby using an RDF
was stew ped. That *you* might have survived means only that *you* were lucky,
NOT fricken smart.

Get over it, AND thank your lucky stars.

okay, besides where the signal came from, over the nee, what else does the
RDF
equipment tell _you_?


And again, you're too stupid to understand or be able to make any use of
that information.
Keep reading the Bowditch, Jax

I see you are trying to make some stupid "Jax" point here, so I'll bite.
In the days when we were all making use of RDF (either for a fix or a
homing beacon or danger bearing) the "equipment" told us three possible
things: Station identity, relative bearing, or true bearing, to the tower.

Are you looking for something else?

I've used them on ships

*that* of course is exactly the same as a recreational sailboat.

I had one on my 26' Contessa,

yes, of course. that explains all.

which I was
able to use to get some relatively accurate fixes (at least accurate
enough for my needs).

sure, plus or minus 100%, distance. good enough to miss the granite ledges 60
yards away, right?

oh?

jeffies, you said it all with:


I haven't used RDF


that we knew when you said it was accurate on a recreational sailboat to 2
degrees.


Everything I knew about RDF came from the Ray-Jeff manual,


if you hd paid attention, and thought things through, you would not have
been
plowing through the granite ledges blindly in fog trusting your RDF to keep
you
safe.

God takes care of fools and little children, jeffies. you got lucky.
other
people didn't.


Jax ....Again .... all you know is what you read. YOU have little or
NO practical experience!!!
