The ADIF standard calls for the field to contain a numeric code that relates to the DXCC Entity or country. CQRLog puts the country Prefix in the field instead e.g. "G" instead if "223".
While this is very user friendly for some, it can cause problems for others. This data is in the log in the ADIF field.
What I'd like to see is an option in the Preferences -> Export Tab that allows the selection of country code (numeric) or country Prefix to be inserted into the DXCC field when exporting to ADIF files.
Alternative could be a MYSQL report which does the same thing, maybe.
