Objective: For Amateurs worldwide to exchange QSO information with as many stations as possible on the 10 meter band.
Online Log Submission: Participants can now submit their Cabrillo-formatted contest logs via the web. A new online log submission web page can be used to upload your log as a file or by copy-and-pasting the log text into a text window. The log will then be checked for proper formatting and completeness before uploading to the log-checking database. You will then receive a confirmation number and a confirming email. If any errors or discrepancies are discovered, they will be clearly labeled so that you can fix the log and try again. The email log submission process is still available if you prefer to use that method and all accepted logs will be listed on the ARRL Logs Received page.

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).
5.1. 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).
188.8.131.52. 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.
6.1. 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 only transmit one signal at any given time; alternating CQs on two or more frequencies using the same band and mode is prohibited.
6.4. All CW contacts must take place below 28.3 MHz.
6.5. Stations that enter a mixed-mode category may change modes at any time.
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.

8.3. All entries must be uploaded, or postmarked by 2359 UTC December 16, 2018.
8.4. Cabrillo log files require exchange sent, category entered, power, and ARRL/RAC section, as defined in the General Rules for All ARRL Contests.
8.5. Computer-generated logs not in Cabrillo file format may be designated as check logs.
8.6. Paper entries must be mailed to 10 Meter Contest, ARRL, 225 Main St, Newington, CT 06111.
