The N3FJP Country Files were released on 16 October 2025.

The following information can be found at:

   https://www.country-files.com/n3fjp-info/


   This is the source of the country file for logging software written by
   Scott N3FJP.

   You can follow this link to the Version History to see the date of the
   most recent release.

   IMPORTANT: This country file is only for users of AC Log 4.0 (and
   later) and the related contesting programs. This file contains more
   prefix and callsign mappings than the older versions of AC Log will
   support. In fact, if you try to use these files with one of these older
   versions of AC Log, your software will not work.

Installation Instructions

   If you are using a current version of the N3FJP software, you should
   see this when you start the program and there is a new country file
   available:

   If not, to update the country and prefix files, use this menu option:

     Files -> Download Country Files From AD1C

   To update all of N3FJP’s software, download all three files.

Checking your Installation

   To verify that you have the new version of the files, try to log the
   callsign VERSION and then look in the Country field in the logging
   window (normally on the right). You should see a different country name
   come up for each country file release. The expected country name can be
   found in the Version History as the Version entity. Don’t save this
   “QSO”, use Clear to erase the callsign.

   To see if the country files installed correctly, click on Awards, then
   “States, Counties, Countries Other”. Leaving the “List only valid
   entries” box checked, click on the Calculate button. In the Countries
   section, the total of Worked + Remaining should match the number of
   entities in the country file, which is also included in the Version
   History.
