#Country File

The country file is the data file used by logging software to assign each callsign to a country, a zone and a continent. It is updated from time to time when new prefixes, new entities or changes in the rules appear. A logger with an outdated file can show the wrong multiplier status or the wrong zone for a rare station. Articles under this tag explain why updates matter before a big contest and what can change for the score. They keep to general principles and refer to the official lists for details.
