Be careful what you publish for accuracy, there are
conflicting reports about what takes place on VLF/LF/MF - lots of inaccuracies.
ie carriers seen but no ID then the questions on
the reflector, was that you if not who was it
!!!!!!!!!!!!!!!!!
I saw an X then a Y who was that? Too much
guesswork and no positive ID
Published articles need hard facts and some people
would believe anything they read. It is like newspapers often the facts are
distorted to make a good story and it is hard to tell FACTS from
FICTION
