3. Entry Categories:
            3.1. Single Operator (use of spotting networks is NOT PERMITTED):
                        3.1.1. QRP (5 watts or less)

                        3.3.1. Low Power (150 watts or less)
                        3.3.2. High Power (1500 watts or less or your country's maximum power limit, whichever is less)
                        3.3.3. Includes single operators using spotting networks.
                        3.3.4. This category is mixed-mode only.

4. Contest Exchange:
            4.1. W/VE stations (including Hawaii and Alaska) send RS(T) and state or province (District of Columbia stations send signal report and DC).
            4.2. DX stations (including KH2, KP4, etc) send RS(T) & sequential serial number starting with 001.
            4.3. Mexican stations transmit RS(T) and their state.
            4.4. Maritime mobile stations send RS(T) and ITU Region (R1, R2 or R3).

5. Scoring:
            5.1. QSO points:
                        5.1.1. Two points for each complete two-way phone QSO.
                        5.1.2. Four points for each two-way CW QSO.
            5.2. Multipliers: (counted once on phone and once on CW).
                        5.2.1. Each US state and the District of Columbia.
                        5.2.2. Canada: 14 provinces - See Appendix A at bottom for complete list.                
                        5.2.3. Mexico: 32 states - see Appendix B at bottom for complete list.
                        5.2.4. DXCC countries (except US, Canada and Mexico).
                      KH6 and KL7 participate and count as US states, not DXCC Entities.
                        5.2.5. ITU regions (maritime mobiles only).
             5.3. Final Score: Multiply QSO points by total multipliers (the sum of states/VE provinces/Mexican states/DXCC countries/ITU regions per mode).

Example: KA1RWY works 2235 stations including 1305 phone QSOs, and 930 CW QSOs, for a total of 6330 QSO points. She works 49 states, 10 Canadian call areas, 23 DXCC entities and a maritime mobile station in Region 2 on phone for a total of 49+10+23+1 = 83 phone multipliers. On CW she works 30 states, 8 Canadian call areas, and 19 DXCC countries for a total of 30+8+19 = 57 CW multipliers.  Her final score = 6330 QSO points x (83+57) multipliers = 6330 x 140 = 886,200 points.

6. Miscellaneous:
            6.1. Single Operator Mixed-Mode and Multioperator stations may work stations once per mode.
            6.2. Your call sign must indicate your DXCC country if competing as DX. (N6TR in Oregon does                 not send N6TR/7, but K1NO in Puerto Rico must send K1NO/KP4 or KP4/K1NO)
            6.3. All entrants may transmit only one signal at any given time.
            6.4. All CW contacts must take place below 28.3 MHz.

7. Awards: Certificates will be awarded to:
            7.1. The highest-scoring Single Operator station (in each category) from each ARRL/RAC Section, Mexican state and DXCC country.
             7.2. Top Multioperator entries (in each category) in each ARRL Division, Canada, Mexican state and each continent.
            7.3. Additional certificates will be awarded as participation warrants.

8. Miscellaneous:
            8.1. All logs generated by computer must be submitted as an ASCII text file in the Cabrillo file format. Paper printouts of the electronic file are not acceptable substitutes.
            8.2. Hand-written paper logs are acceptable submissions.
            8.3. All entries must be emailed or postmarked by 0000 UTC Wednesday, January 11, 2012.
