"JAXAshby" show that he is getting completely delusional:
do jeffies, *you* made the statement that RDF -- as used by *you* in a fog off
the coast of Maine in a sailboat -- was accurate to 2*, or maybe 5*.


You have a serious reading disability. Here's what I said:
"It was considered to be accurate to 2 degrees, but I generally assumed I'd get
no better the 5 degrees with my small unit. "

No better than 5 degrees, sometimes worse, but no better.


neither of which is even close to true. for all the reasons I laid out.


YOU explained why YOU would be unable to used RDF. Your explanation had little
to do with the way I used it.


jeffies, *you* were talking about a sailboat, NOT a large ship at sea with
professional RDF equipment professionally installed professionally maintained
and professionally operated.


So?


In addition, *you* failed to take appropriate account of the boat's movement.


The boat doesn't have to be moving for RDF to work. Yet another stupid thing
you've said about this.


In addition, *you* failed to understand that two bearings gives a total
potential error greater than the error of either


This is non-sensical. One bearing leaves you with a very large possible area.
Two bearings (presumably the second crossing the first) greatly reduces that
area. This is a very simple concept, jaxie. Any child would understand it.

Nor do you need to take two bearings to take advantage of RDF. In fact, it was
more typical to only use one RDF bearing, combined with some other techniques,
such as a sounding.

Nor do you need to take 2 bearings to get a position from RDF. There is a very
simple way to get a position from one RDF bearing, but you haven't figured it
out yet, have you jaxie?



In addition, *you* failed to understand the Area of Potential Position is a
frickken AIR EE AH, not a point.


You should see a doctor about that condition, jaxie.


In addition, *you* failed to understand the difference between an area and a
point with jitter.


you have the jitters now?


In addition, *you* failed to understand just what the chances are getting
within 2* with surperb equipment on solid land with zero atmospheric
disturbances (such as the fog you said you were in, or rain, or temp
variations, or sunspots, or time of year).


Yea, fog really slow down the radio waves.


jeffies, you know nothing about the subject but a cookbook approach. you
generalized your cookbook recipe to a universal truth, and failed.


WTF are you talking about? I never described how I used it at all.


In addition, *you* failed even more so by not understanding just how far off
you were.


In fact, I never actually said I used it at all for navigation, other than to
home in on a beacon. In fact, all I did was to say that I had RDF on board when
I cruised Maine. You completely embaressed yourself arguing with a claim I
never made! What a putz!
