1. Object: For Amateurs worldwide to exchange QSO information with as many stations as possible on the 10-meter band.

2. Date and Contest Period: Second full weekend of December. Starts 0000 UTC Saturday; ends 2359 UTC Sunday (December 9 - 10, 2006).

2.1. All stations operate no more than 36 hours out of the 48-hour period.
2.2. Listening time counts as operating time.

3. Entry Categories:

3.1. Single Operator: (9 categories)

3.1.1. QRP.

3.1.1.1. Mixed Mode (Phone and CW).
3.1.1.2. Phone only.
3.1.1.3. CW only.

3.1.2. Low Power.

3.1.2.1. Mixed Mode (Phone and CW).
3.1.2.2. Phone only.
3.1.2.3. CW only.

3.1.3. High Power.

3.1.3.1. Mixed Mode (Phone and CW).
3.1.3.2. Phone only.
3.1.3.3. CW only.

3.2. Multioperator, Single Transmitter, mixed mode (only).

3.2.1. Includes single operators using packet or spotting assistance.

4. Contest Exchange:

4.1. W/VE stations (including Hawaii and Alaska) send signal report and state or province (District of Columbia stations send signal report and DC).

4.1.1. Novice and Technician Plus stations sign /N or /T on CW. If used, you must indicate /N or /T on your summary sheet.

4.2. DX stations (including KH2, KP4, etc) transmit signal report and sequential serial number starting with 001.
4.3. Maritime mobile stations send signal report 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.
5.1.3. Eight points for CW QSOs with US Novice or Technician Plus stations signing /N or /T (28.1 to 28.3 MHz only).

5.2. Multipliers: (per mode, phone and CW).

5.2.1. Each US state and the District of Columbia.
5.2.2. Canada [NB (VE1, 9), NS (VE1), QC (VE2), ON (VE3), MB (VE4), SK (VE5), AB (VE6), BC (VE7), NWT (VE8), NF, (VO1), LB (VO2)], YT (VY1), PEI (VY2) NU (VYØ).
5.2.3. DXCC countries (except US and Canada). KH6 and KL7 participate and count as US states and send HI or AK as that part of their exchange.
5.2.4. ITU regions (maritime mobiles only).

5.3 Final Score: Multiply QSO points by total multipliers (the sum of states/VE provinces/DXCC countries/ITU regions per mode). Example: KA1RWY works 2245 stations including 1305 phone QSOs, 930 non-Novice CW QSOs, 10 Novice CW QSOs, for a total of 6410 QSO points. She works 49 states, 10 Canadian call areas, 23 DXCC entities and a maritime mobile station in Region 2 on phone and 30 states, 8 Canadian call areas, and 19 DXCC countries on CW for a total multiplier of 140. Final score = 6410 (QSO points) X 140 (multiplier) = 897,400 points.

6. Miscellaneous:

6.1. Single operator mixed-mode and multioperator stations may work stations once on CW and once on SSB.
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).
6.3. All entrants may transmit only one signal on the air 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 and DXCC country.
7.2. The top scoring Novice/Technician Plus station (in each category) in each ARRL Section.
7.3. Top multioperator entries in each ARRL Division, Canada and each continent.
7.4. Additional certificates will be awarded as participation warrants.
