shen, every last country signatory to the radio treaty of 1920 (1919?)
required
their radio stations to broadcast their call sign, frequency and city every
ten
minutes they were on the air. This was done specifically as an aid to
navigation for ships at sea and aircraft in the air.

recreational boats often did not have any such equipment until into the
1970's,
1980's and in some cases 1990's. Lots of recreational vessels were lost due
to
hitting rocks in reduced visability conditions until lorans and later gps's
became common. Stories of vessels lost such were common in the boating
magazines until the late 1980's.

All well and good. However there were many areas of the world, where the
coverage for RDF was poor and not all charts carried the exact locations of all
transmitters.
To all this, add the corrections needed for using stations, inland, with great
distance, and, the skill of the operator and proper alignment of equipment and
you'd find any number of limitations associated with it's use.
I.e., it wasn't a cure-all, just another aid that had to be used with caution.
By the 70's, a high percentage of recreational boaters in the US were beginning
to use Loran, as it didn't generally require the skill that RDF did.

take what ever you want, gene. you are hopeless. if I were to shine a
flashlight in your eyes, I would see the back of your skull.

gene, just admit you didn't then and don't now know squat about navigation,
air
or sea, and be done with it.


I take it, then, that you are admitting you were and are wrong.

gene, if you would be so kind as to email your ssn, I will be glad to report
you to the FAA as one who claims to fly in IFR conditions without required
instruments, just blindly wandering around in airspace. that way we can let
the FAA explain the rules to you, as they suspect, later revoke, your
license.


Just give them my name, Jax... they have my SSN.... it is the number on my
pilot license...

G Actually, I'm pointing out the errors in your "general" statement regarding
RDF and the overall usage of it by those in the marine environment.
For the most part, most ships only used signals from RDF stations on the coast
that were designed for marine use, as the others required too much in the way
of corrections to be reliable other than as a possible indication to help
correct their DR.
I'd like to hear your explaination of fixes using sounds/smells from shore and
fathom curves.... the above stuff, anyone can get from some light reading.

shen, the radio treaty of 1919 or 1920 specifically included the requirement
that all commercial radio stations broadcast their call letters, their
frequency and city every ten minutes they were on the air. This was done
specifically as an aid to navigation for ships at sea and aircraft in the air
(when it would come about that aircraft would be making long distance flights).

specifically for navigation, shen, specifically.

Jax, specifically, that's terryific. Problem is that all those inland radio
stations have a problem with "coastal refraction" which makes their use
doubtful as regards accuracy.
Course, there were a number of other possible errors also, which, once again,
removed RDF from the cure-all category, especially for a Novice, such as
yourself.

of course,shen, *your* grandfather was an idiot. Mine was not.

Haven't got a clue how that bit of nonsense relates, other than it's a "jaxism"
for "I don't have an intelligent answer".
S'ok jax we don't expect answers from you, much less intelligent or
knowledgeable ones .... RDF on boats was probably before your time and
undoubtably beyond your abilities.
