I have uploaded new master callsign database files to http://www.k1ea.com 
.  You can also get to them through the CT Vault.

Of course, a big THANK YOU goes out to everyone who sent me logs (too many 
to mention).  I lost count of how many hours this took (at least 20, 
probably closer to 40).  I got very close to running out of disk space at 

Special thanks to Mario, S56A who supplied a database of known-good 
Slovenian callsigns.

This year I tried to remove many of the portable designations to leave just 
the base callsign (ie. KL7NL/4 is now just KL7NL).  Of course, there are 
still many portable callsigns in the database (like F/OK1EE), but I hope 
that they are not duplicated too much.

With the new PA vanity callsigns, there are surely a lot of former PA calls 
in the database.  Does anyone from The Netherlands have a list of OLD->NEW 
callsigns so I can fix the database?

I have attached some statistics below (set your E-mail program to display 
fixed-width) from the 4 years I have been building the database.  Remember 
that each year, the database starts out empty, i.e. I do not use any data 
from the previous database.  All databases were generated using a threshold 
of 10, i.e. a call had to show up 10 times to be counted in the 
database.  The numbers represent the total number of callsigns in that 
category.  You will see that this year has a much larger database of 
callsigns than in previous years.
