QSO/HRD with own country counts 0 (zero) point but is good for the multipliers
QSO/HRD with own continent counts 1 (one) point,
QSO/HRD with different continent counts 3 (three) points,

The same station can be contacted on the same band once on SSB/CW/RTTY but only
the first QSO is good for multiplier credit.
9. Final score.
The Final Score is the sum of QSO/points from all bands multiplied by the sum of
multipliers from all bands.
Listeners are required to log both the callsign of the station heard and of the
correspondent station. Score is calculated based only upon the station heard using the
same rules as per the transmitting stations. A callsign may appear NOT more than 3
