Thanks to those that submitted logs for analysis and
to a "Super Check Partial" database, I have completed
an initial analysis of contest-active prefixes in the
USA.
What you see below is only for the AA0-AL9 prefix
block. It shows the prefix and the number of times
that it appeared in other people's logs.
It is one of those FWIW things. I found the data to
be most fascinating by importing it into Excel and
plotting it. Apparently, the most rare USA prefixes
are those from AD and beyond (in this block, anyway).
