Note: There are some minor changes to the rules for 2018. Please read carefully.
SSB: October 27-28 CW: November 24-25
Starts 00:00:00 UTC Saturday Ends 23:59:59 UTC Sunday
I. OBJECTIVE: For amateurs around the world to contact as many other amateurs in as many CQ zones and countries as possible.
II. BANDS: Six bands only: 1.8, 3.5, 7, 14, 21 and 28 MHz. Observance of established band plans is strongly encouraged.
III. CONTEST EXCHANGE: SSB: RS report plus CQ Zone number of the station location (e.g., 59 05). CW: RST report plus CQ Zone (e.g., 599 05).
A. Score: The final score is the result of the total QSO points multiplied by the sum of zone and country multipliers. Example: 1000 QSO points * (30 Zones + 70 Countries) = 100,000 (final score).
B. QSO Points: Stations may be contacted once on each band. QSO points are based on the location of the station worked.
C. Multiplier: There are two types of multipliers.
V. ENTRY CATEGORIES:
A. Single Operator Categories: One person (the operator) performs all operating and logging functions. There is no limit on operating time or band changes. Only one transmitted signal is permitted at any time.
1. Single Operator: QSO finding assistance of any kind is prohibited (see VIII.2).
a. High Power (All Band or Single Band): Total output power must not exceed 1500 watts.
b. Low Power (All Band or Single Band): Total output power must not exceed 100 watts.
c. QRP (All Band or Single Band): Total output power must not exceed 5 watts.
2. Single Operator Assisted: Entrants in this category may use QSO finding assistance (see VIII.2).
a. High Power Assisted (All Band or Single Band): Total output power must not exceed 1500 watts.
b. Low Power Assisted (All Band or Single Band): Total output power must not exceed 100 watts.
c. QRP Assisted (All Band or Single Band): Total output power must not exceed 5 watts.
B. Single Operator Overlay Categories: Any Single Operator entrant who meets the requirements may ALSO enter one of the categories shown below by adding the appropriate CATEGORY-OVERLAY line in the Cabrillo log file header. Overlay category entries will be listed separately in the results; scored as All Bands; and grouped by High Power and Low Power (includes QRP).
1. Classic Operator (CLASSIC): The entrant will use only one radio, no QSO finding assistance, and may operate up to 24 of the 48 hours – off times are a minimum of 60 minutes during which no QSO is logged. If the log shows more than 24 hours of operation, only the first 24 hours will be counted for the overlay score. The one radio must not be able to receive while transmitting. Single Operator Assisted entries are not eligible for this category.
2. Rookie (ROOKIE): The operator was first licensed as a radio amateur less than three (3) years before the date of the contest. Indicate the date first licensed in the SOAPBOX field. Previous Rookie winners are ineligible for plaques in this category.
C. Multi-Operator Categories (all-band operation only): Any number of operators is allowed. QSO finding assistance is allowed. Only one transmitted signal per band is permitted at any time.
1. Single Transmitter (MULTI-ONE): Only one transmitted signal on one band permitted during any 10-minute period (run station/signal). Exception: One — and only one — other transmitted signal (multiplier station/signal) may be used during any 10-minute period, if — and only if — it is on a different band from the run transmitter and the station worked is a new multiplier. The run and multiplier transmitters are governed by independent 10-minute rules. Ten-minute periods begin with the first QSO on a band. The log must indicate which station/signal (run or multiplier) made each QSO. The multiplier station/signal may not call CQ (solicit contacts). Please be sure to read the Multi-Single FAQ section at <cqww.com/rules_faq.htm>.
a. High Power: Total output power must not exceed 1500 watts on any band at any time.
b. Low Power: Total output power must not exceed 100 watts on any band at any time.
2. Two Transmitters (MULTI-TWO): A maximum of two transmitted signals on two different bands may be used at any time. The log must indicate which station/signal made each QSO. Each station/signal may make a maximum of 8 band changes in any clock hour (00 through 59 minutes). Total output power must not exceed 1500 watts on any band at any time.
3. Multi-Transmitter (MULTI-UNLIMITED): The six contest bands may be activated simultaneously. Only one transmitted signal per band is permitted at any time. Total output power must not exceed 1500 watts on any band at any time.
D. Checklog: Entry submitted to assist with the log checking. The entry will not have a score in the results and the log will not be made public.
A single-band log will be eligible for a single-band award only. A log containing more than one band will be judged as an all-band entry unless specified as a single-band entry.
A. Certificates: Electronic certificates will be made available for download for everyone that submits an entry.
B. Plaques: Plaques are awarded for top performance in a number of categories. View the current list of plaques and sponsors at <cqww.com/plaques.htm>. Only one plaque will be awarded per entry. A station winning a plaque will not be considered for a sub-area award; the plaque will be awarded to the runner-up in that area.
VII. CLUB COMPETITION:
The club score is the total aggregate score from logs submitted by members. There are two separate club competition categories.
A. USA Clubs: Participation is limited to club members residing within a 250 mile radius circle from the center of club area.
B. DX Clubs: Participation is limited to club members residing within EITHER the DXCC country where the club is located OR within a 400 km radius circle from the center of club.
C. General club rules:
VIII. DEFINITIONS OF TERMS:
IX. GENERAL RULES FOR ALL ENTRANTS:
X. LOG INSTRUCTIONS:
Electronic submission of logs is required for all entrants who use a computer to log the contest or prepare contest logs.
XI. LOG DEADLINE:
The CQ WW DX Contest Committee is responsible for checking and adjudicating the contest entries. Entrants are expected to follow the rules and best amateur radio practices. Violation of the rules of the contest or unsportsmanlike conduct may lead to disciplinary action by the Committee.
A. Unsportsmanlike Conduct: Examples of unsportsmanlike conduct include, but are not limited to:
Audio Recordings: Any single operator entrant (see V.A.1) competing for a top five finish at the (a) World, (b) Continent, or (c) USA levels, including Classic Overlay, must record the transmitted and received audio as heard by the operator for the duration of the contest operation. The recording must be in a common format (e.g., mp3) and should include the audio to each ear as a separate channel. The recording must be a continuous recording (not a recording of individual QSOs). Time “off the air” (when not transmitting or receiving) does not have to recorded. The recording may be requested by the Committee within 120 days after the log deadline to help adjudicate the log. The recording files must be provided by the entrant within 5 days of the request. If no recording is made available, the Committee may reclassify to an appropriate category, reclassify to Checklog, or disqualify the entry.
C. Disciplinary Actions: In the event of a violation, the entrant is subject to disqualification at the discretion of the Committee.
D. Log Checking: All logs are checked using custom software and human judgment.
By submitting a CQ WW DX Contest log, and in consideration of the efforts of the CQ WW DX Contest Committee to review and evaluate that log, an entrant unconditionally and irrevocably agrees that he/she has: 1) read and understood the rules of the contest and agrees to be bound by them, 2) operated according to all rules and regulations that pertain to amateur radio for the station location, 3) agreed the log entry may be made open to the public, and 4) accepted that the issuing of disqualifications and other decisions of the Committee are official and final. If an entrant is unwilling or unable to agree to all of the foregoing, the entrant should not submit the entry or submit the entry as a Checklog only.
