This release was derived from 176 logs from the June, July, & Sept 2012 and
the January 2013 VHF Contests.  The Super Check Partial Database contains
6,987 calls and the Prefill Database 6,768 calls.

Some comments on the methodology:
All calls are added to the Super Check Partial Database.  Calls that were
logged as /P (Portable), /M (Mobile), and /R (Rover) are not added to the
Prefill Database.  A Utility is used to identify calls not so marked that
appear in multiple Grid Squares.  Calls shown as having operated from
physically adjacent Grid Squares are dropped.  Where the multiple Grids are
obviously a result of incorrect logging in a few Grids, the call is
retained.  When in doubt the call is dropped.

All of the calls in the Database are checked to see if the call is current
issued.  A run of the calls showed 255 were not-issued calls. Of these 7
were -SK-'s and 19 were the result of callsign upgrades.

The big question is always what to do with the calls that only appear in one
log.  Most of the non-issued calls only appear in one log.  However there
are a considerable number of valid calls, 2373, that only appear in one log.
I know some of these to be active operators.  I would like to toss all calls
only appearing on one log, but I have to believe the number would be much
smaller IF I RECEIVED MORE LOGS.

This is a plea to the community to increase participation.  The processing
software simply absorbs the calls of station in the Contest.  There is no
other use of your Cabrillo and you submissions are only kept for one year.

After the June VHF Contest, PLEASE consider E-Mailing you Cabrillo file to
me at   zephd at indy.rr.com
