- SCORE:
All confirmed QSOs will be valid, with station worked once per band.
4.1. Brazilian stations
Contacts between stations in Brazil = 2 pts.
Contacts between stations in Brazil and DX = 3 pts.
4.2. DX stations
Contacts between stations in the same country = 1 pt
Contacts between stations in different countries = 1 pt
Contacts with stations in Brazil = 3 pts.
4.3. all stations
CRAEC Director Station (PT2CVA) = 10 pts. (Hors Concours)
MIL, YL, TEEN, FD, MIL, HQ or RB stations = 5 pts. (regardless of country)
QRP stations = 3 pts. (regardless of country).
4.4, QSO Validation
4.4.1. With a station that did not send a log, it will be valid if the callsign appears in at least 5 valid logs.
4.4.2. Indicatives present in only 01 (one) single Log will be called UNIQUES and considered as QSO registration errors.
5.0. MULTIPLIERS:
Two types of multipliers will be used:
M1) a multiplier per different Brazilian UF contacted per band.
Example PT2AA logged in at 28,000 Hz and 14,000 Hz add up to 02 (two) multipliers
M2) a different multiplier per country computed once across all bands.
Example N8OO logged in at 28,000 Hz and 3,500 Hz adds 01 (one) multiplier.
Attention: In the N1MM module, stations with messages or Exchange, “MIL, YL, TEEN, FD, MIL, QRP, HQ or RB” are not
being counted as UF multipliers, but in the CVA calculation program, they will be counted as multipliers normally.
Contacts with stations in the country are allowed for multiplier credit.

Finding it is part of everyone’s effort and this procedure is considered unsportsmanlike behavior. One of the ways to prove an auto spot, or similar procedure, is to verify that the IP address used during the contest matches the
IP address used by the competitor, with his own callsign, to make a spot before or after the contest, subject to disqualification, in the event of a proven complaint.
