Rules for the 77th Oceania DX (OCDX) Contest 2022

The following notes are a simplified summary


  1. The deadline for submitting logs is 31 October 2022.
  2. Two new plaques (sponsored by Oscar Reyes VK3TX) are being introduced this year to help promote participation by younger entrants – one to the highest scoring youth entrant (no older than 25 years age) from outside Oceania in any of the Phone Single Operator categories and the other to the highest scoring youth entrant (no older than 25 years age) from Australia in any of the Phone Single Operator categories.
  3. A new plaque is also being sponsored by Rippletech Electronics (VK3TZ) for awarding to the Local club or contest club from North America with the greatest number of member stations participating in the contest. All North American entrants who wish to be considered for this plaque must clearly state the full name of their club in the CLUB: field of the Cabrillo log file header.
  4. Rule 13b has been updated to clarify that an SWL entrant who correctly hears both ends of a QSO between two eligible stations can claim points and multiplier credits for hearing the two stations but they must each be recorded on separate lines in the log so both call signs appear in the ‘heard’ column.
  5. Entrants are reminded of the need to observe any COVID related restrictions (e.g. social distancing and travel constraints) that may be in place for the contest dates.
  6. Electronic logs are to be submitted using the form at Please contact the Contest Committee at if you are encountering difficulty in submitting your log.
  7. Electronic logs are to be in Cabrillo format which is generated by all popular contest logging software programs. Alternatively, entrants can use the forms at
  8. Only one entry may be submitted by each operator or team of operators (Rule 6a).
  9. If the station worked does not provide a serial number for the OCDX Contest, then log the received number as 001. See Rule 8.
  10. A reminder that logs from Single Band entrants should include all contacts made during the contest period, even if some contacts were made on other bands. Only contacts made on the band specified in the Cabrillo header or summary sheet will be used for scoring purposes.
  11. Indonesia entrants are reminded that the Indonesia amateur radio regulations do not permit the YH club prefix to be used in the OCDX and other national or international amateur radio contests. Only the 7A, 7I, 8A or 8I club prefixes may be used for this purpose.

Band 160M 80M 40M 20M 15M 10M
Points per QSO 20 10 5 1 2 3
  • The Phone and CW contests are scored separately.
  • Prefixes are multipliers (e.g. N8, W8, WD8, HG1, HG19, KC2, OE2, OE25, LY1000, VK2 …) on each band on which you work them.
    • For multiplier purposes, prefixes and callsigns without numbers are notionally assigned a zero e.g. PA/N8BJQ counts as PA0, and XE/KT5W counts as XE0. All callsigns should however be logged as sent.
    • Maritime mobile, mobile, /A, /E, /J, /P, or interim license class identifiers do not count as prefixes.
    • Special event, commemorative and other unique prefix stations are welcome.
  • The total score is the (sum of the Contact Points) multiplied by the (sum of the Multipliers).


  • Transmitting Single Operator:
    • QRP (SO QRP) 5 watts
    • low power (SO LP) 100 watts
    • high power (SO HP) the lesser of license limit or 1500 watts
  • Transmitting Multiple Operators
    • Single Transmitter (M1)
    • Two Transmitters (M2)
    • Multiple Transmitters (MM)
  • Short Wave Listener (SWL)
  • DXcluster assistance is permitted in all categories, with the usual restrictions (see the full rules for details)
  • Entries on individual bands are supported.
  • World Stations operate in a separate category to Oceania stations


  • Participants typically call “CQ Oceania” on phone, and “CQ OC” on CW.
  • Contest exchanges are signal reports plus a serial number, starting at 001.
  • Be careful to log callsigns and reports accurately, especially multipliers, since typos can be costly.
  • If someone does not send you a serial number, log them as serial number 001.
  • To help the adjudicators cross-check other entrants’ logs, please log every completed QSO:
    • Log zero-point QSOs (e.g. if DX stations work other DX stations)’
    • Log any duplicate QSOs’
    • Single band entrants: log your QSOs made on all bands (the Cabrillo header tells us which band you are entering)’
    • If you participate but choose not to enter, a checklog would be welcome for the same reason.



  • The OCDX contests are adjudicated electronically, hence we need your electronic logs.
  • If possible, use contest logging software to generate a Cabrillo file, then upload it using the on-line submission form.
  • Otherwise please use the online form or some other means to generate a valid plain text column-aligned Cabrillo file, then upload that.
    • Provided you made less than 50 contacts, you can mail in a legible paper log with a summary sheet (see the official rules for details).
  • Get your log in before November!
  • Every submitted entry will be checked and given a final score as part of the adjudication process … but naturally you are welcome to calculate your claimed score and hope that’s close!
  • A veritable profusion of certificates, trophies and plaques will be awarded.
  • Please email the Committee at if you have any problems entering.
  • Good luck!
