Additional Information :

– Maritime mobile station (/MM) does not count as valid multiplier. For example: PY4KL/MM

– The CWJF Group encourages the use of special prefix by ham radios from Brazil and other South American countries, mainly because they are valuable multipliers.

– Will be added a zero (Ø) after the second letter on those prefix without number, Example: ZP/PY4KL, the prefix will be considered as ZPØ only for log check propose. The participant should not modify it on his log.

11 – FINAL SCORE :

For all stations (regardless of country or continent), the final score is the result of the sum of points obtained in each band, multiplied by sum of multipliers (SA prefix + DXCC countries):

Final Score = QSO points x (SA prefixes per band + DXCC any band)

Example: 400 QSO points x 50 mults (40 SA Prefixes + 10 DXCC) = 20,000 points as Final Score.

12 – CERTIFICATES AND PLAQUES :

Certificates and Plaques will be awarded by CWJF Group. These awards are sponsored by individual radioamateurs, Radio Clubs, Groups and Companies.
