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
