Dupe QSOs are counted on different bands. We recommend to work short QSOs with the following minimum information exchange: RSQ, name, locator.
We sum up the results in a few subgroups in which participants do not need to be declared, as the organizers will form themselves a subgroup on the basis of data from the logbooks.
 |
Subgroup "DOUBLE 6": 6 х 6 = 36 QSO - the subgroup of participants who worked at least 6 QSO in DOMINO on each of any 6 (7, 8 or 9) bands. |
 |
Subgroup "DOUBLE 5": 5 x 5 = 25 QSO - the subgroup of participants who worked at least 5 QSO in DOMINO on each of any 5 bands. |
 |
Subgroup "DOUBLE 4": 4 x 4 = 16 QSO - the subgroup of participants who worked at least 4 QSO in DOMINO on each of any 4 bands. |
 |
Subgroup "DOUBLE 3": 3 x 3 = 9 QSO - the subgroup of participants who worked at least 3 QSO in DOMINO on each of any 3 bands. |
 |
Subgroup "DOUBLE 2": 2 x 2 = 4 QSO - the subgroup of participants who worked at least 2 QSO in DOMINO on each of any 2 bands. |
 |
Subgroup "DOUBLE 1": 1 x 1 = 1 QSO - the subgroup of participants who worked at least 1 QSO in DOMINO on one band. |
 |
Subgroup "DOUBLE 0": 0 x 0 = 0 QSO - a subgroup for SWL. |
Thus, actually game in "Russian DOMINO" will be held in six subgroups, and the seventh subgroup for SWL.
