I noted that during the contest, especially on Saturday night, the popular
propagation summary http://dx.qsl.net/propagation/ was reporting an A index of
zero (0) and a K index of zero (0). I don't remember another time when this
was true, especially during a contest.

Can one surmise from the A and K indices being at or very near Zero that the
these indicators play a significant role in the traditional 'path skewing' that
is known to occur on Topband? Auroral activity appears to have been quite low
over the weekend. This op was hopeful that a near polar path was possible
under such conditions. Perhaps instability in the ionosphere contributes to
the skewing that normally occurs? Hence, no instability = no skewing = no EU
DX in northern US latitudes or western longitudes.
It is too early to really evaluate the results in grand detail, but I would
like to start by collecting a summary from each of the DX stations operating as
to the # of QSOs by state so as to facilitate a closer examination. I know
from previous analysis of logs that confidentiality is important to many
people. To protect the source (the real owner of the information), I will
attempt to report the results generically as opposed to describing specific
results from any given station. No need to let anyone unnecessarily gloat or
be embarrassed in any way. Your data and your call will not be connected in my
report and your responses will not be released to anyone. As always, to
protect the integrity of the log checking process, refrain from sending me your
logs at this point, at least until the time period for log submissions has
passed. Please indicate in your reponse your approximate location (country)
and latitude. Send your data here ford@cmgate.com
In an effort to further the scientific nature of this analysis, I will report a
summary of some sort on the Topband reflector (here) as soon as one is compiled.
