Does Martin still get issues regarding the country files? For example, YU4EBL currently unconditionally resolves to Bosnia-Herzegovina (501) from the CallResolution table. I worked YU4EBL many times in the 1980's so for DXCC it is Yugoslavia (296). [It is unfortunate that the DXCC desk uses 296 for Serbia now so it can be confusing for the older Yugoslavia QSOs.] WP2Z, N6KB, KP4US, KL7CQ, and a few others are similar in that they resolve unconditionally to a country but all of my QSOs are confirmed in their original country (e.g., WP2Z resolves to USA - 291 but all my QSOs are confirmed for Virgin Islands - 285).
KA2xxx calls seem to resolve to Japan (339). Only KA2xx calls should resolve to Japan. KA2xxx are USA (291).
There are other issues such as I have DXCC credit for 3V8AA for a 1982 QSO but the tables say no DXCC credit. Trying to keep the tables accurate for acceptable DXCC credit is tough. Some calls (e.g., 3V8BB) are reused many times and some of the uses are acceptable and some are not which could lead to many table entries.
There still others that just seem to resolve incorrectly. For example, CR9BH in 1982 resolved to Madeira Island (256) but should have been to Macao (152 - confirmed and DXCC verified).
