The DXCC Desk Clarifies Russian Prefixes Which Count for European Russia
For the purposes of the DXCC and WAC awards, the following Russian prefixes count as European Russia:
Any call with the prefixes UA through UI and the numbers
1, 2, 3, 4, 5, 6, 7.
Any call with the prefix U and the numbers 1, 2, 3, 4, 5, 6, 7.
Any call with the prefixes RA through RZ and the numbers 1, 2, 3, 4, 5, 6, 7.
Any call with the prefix R and the numbers 1, 2, 3, 4, 5, 6, 7.
Exception:
Prefixes R, U, UA-UI, and RA-RZ, the number 2, and suffixes beginning with F or K, count as Kaliningrad. Also, some legacy calls such as UA2CZ are in Kaliningrad.
And from 1 December, 2011 forward, any QSO (with any date) with stations using the following prefixes, count for European Russia:
Any call with the prefixes UA through UI, or the prefix U, and the numbers 8, and 9, followed by a suffix beginning with the letters F, G, or X (Perm and Komi).
Any call with the prefixes RA through RZ, or the prefix R, and the numbers 8, and 9, followed by a suffix beginning with the letters F, G, or X (Perm and Komi).
Since Russia joined CEPT, there are stations active with call signs that do not indicate DXCC entity, such as RA/N6TR who operated from Asiatic Russia, and RA/SM6LRR who operates from European Russia. These types of portable call signs will be managed individually in the DXCC system.
