The following notes are a simplified summary


  • OCDX starts and finishes 2 hours earlier than usual this year: the OCDX 2020 Phone and CW contests run from 0600z Saturday until 0600z Sunday.
  • Observe the COVID-19 laws, regulations and guidance that apply in your situation.
  • SWLs please note: a given ‘station being worked’ callsign can only appear in up to 3 consecutive QSOs on a single band, so you can’t simply monitor a single transmitting station, logging everyone he works for hours on end!  Please check rule 7g carefully.
  • Only one plaque or trophy will be awarded per entry. For example, a station winning a continent plaque will not also receive the country award – it will go to the runner-up instead.


Phone contest: 06:00 UTC Saturday 3 October to 06:00 UTC Sunday 4 October 2020
CW contest: 06:00 UTC Saturday 10 October to 06:00 UTC Sunday 11 October 2020

These are separate contests on successive weekends: feel free to enter either … or both!

3. AIM

  • OCDX promotes HF contacts to and from stations in the Oceania region  as well as contacts between stations inside Oceania
    • Oceania transmitting entrants contact as many stations as possible, anywhere in the world.
    • DX transmitting entrants contact as many Oceania stations as possible.
    • Oceania SWLs copy and log as many contest stations as possible, anywhere in the world.

  • 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!
