ignorant fool over the nee, chasing his tail in circles, writes the trash
below:

you asked no question. you chased your tail hoping no one would realize
you
didn't know RDF's were aligned by magnetic compass, so therefore could be
no
more accurate. duh.

no wonder you pontificated.

LOL, glad I was waiting to the end of this session to plonk you....

Yes I did ask a question. To repeat: What does "Ships didn't have mobile
radio compasses, so they weren't aligned each time they were used" refer
to (it's your statement)....care to answer?

As to your other statement .... RDF's signals could be taken either
using magnetic or gyro or fluxgate compasses, and the accuracy was
dependent on a number of factors, but with any of the three, could well
fall into the ranges stated.
New question: How the hell did you think anyone plotted an RDF bearing
if they didn't "align" it with the compass?

otn ... you will be plonked, but I'll hold to see if you can make any
reasonable response.
