Download the OCDX rules Oceania DX Contest


Please download and study
the official 2018 OCDX rules


The official 2018 rules are definitive


The unofficial summary below
is incomplete and purely indicative ...



Dates and times

  • Phone Contest: 08:00 UTC Saturday 6 October to 08:00 UTC Sunday 7 October 2018
  • CW Contest: 08:00 UTC Saturday 13 October to 08:00 UTC Sunday 14 October 2018
  • The Phone and CW events are separate contests: enter either one or both - your choice
  • In most of Oceania (West of the date line), the contest starts on Saturday evening and finishes on Sunday evening
  • The clocks change at this time of year so the contest may start an hour sooner or later than you expect!  For consistency, we always refer to UTC (“zulu”) dates and times.  QSOs must be logged in UTC.

Valid contacts


  • Non-WARC HF bands i.e. 160m, 80m, 40m, 20m, 15m and 10m
  • Entrants will mostly be calling “CQ Oceania”, “CQ contest” on phone, or “CQ OC” or “CQ TEST” on CW, approximately within the following frequency ranges (the amateur bands vary between countries, so tune around and watch DXcluster for new QSOs and multipliers!):






















* To encourage 160m activity, we recommend checking topband at 15 minutes and 45 minutes past the hour
from dawn to dusk in the Pacific.  Keep an eye on your greyline map: the Pacific is massive!  Activity tends
to center around 1850 kHz on phone and 1820 kHz on CW, but please tune around and listen carefully
as topband allocations vary around the world.  Remember those topband QSOs are worth 20 points each.

** Tim K6GEP reminds phone ops down-under to listen at 7128 kHz and up for USA callers.

  • Please be considerate towards non-contestants, nets and so forth, as well as towards other competitors
    • This is a DX contest so entrants will be listening hard for weak signals
    • Unsportsmanlike or selfish conduct is simply not cricket and could lead to score penalties or disqualification
    • Play nicely together ... and remember it is only a hobby

Output power

  • High power = max 1500 watts or license limit if less
  • Low power = max 100 watts
  • QRP = max 5 watts
  • SWL = nil!


  • Single op: one person does everything
  • Multi-one: several operators share a single transmitter: no more than ten band changes per clock hour
  • Multi-two: several ops share two transmitters: no more than eight band changes per clock hour
  • Multi-multi: multiple ops and transmitters but only one transmitted signal and running station per band
  • SWL: Short Wave Listener entries are very welcome in this contest: can you hear Oceania stations?
  • DXcluster, RBN and Skimmer assistance is permitted in all categories, but please play fair - no self-spotting
  • Remote operation is permitted but be sure to identify correctly on-air and comply with all license requirements of the transmitting location (e.g. CEPT rules prohibit remote operating from outside the country)
  • Checklogs are welcome (they help us check and hopefully confirm QSOs claimed by entrants) but they are of course ineligible for awards


  • RS(T) plus QSO serial number starting at 001
    • Multi-two and multi-multi stations use separate serial number sequences for each band
    • Multi-one stations use a single sequence, the same as for single-op stations
  • N1MM Logger+ and other contest logging software can handle all that with ease, and is highly recommended even for casual entrants.  At the end of the contest, simply ‘press the button’ to generate a Cabrillo file ready to check and submit.

Points and multipliers

  • Points depend on the band with a strong bias toward the low bands to encourage and reward LF activity:








Points per valid QSO







  • Multipliers are prefixes per band (similar to the CQ WPX contest)
    • VK1, VK2, ZL1, ZM2, E50, E51, K1, KC1, N1, K1, W1 and so on are all separate multipliers
    • The first VK1 you work on 20m is a multiplier, and so is the first VK1 on any other band
    • /M, /MM, /A, /E, /J, /P and similar license qualifiers do not count as multiplier: only the callsign prefix counts
    • Calls, prefixes or suffixes without numbers are presumed to include zeros e.g. G/ZL2IFB counts as a G0 which may be a multiplier
    • Multipliers make a huge difference to your score so rare prefixes (especially in Oceania!) are in high demand
    • This is a DX contest ... so ... rate is great but mults are magic
    • Take care to log callsigns accurately, especially multipliers: it is well worth taking an extra couple of seconds to confirm a callsign, rather than risk having the QSO points and multiplier disallowed in checking

Win me!Awards

  • Thanks to our generous sponsors, there are numerous trophies and plaques up for grabs
  • In addition to any trophies or plaques, category winners in each continent and country earn winners’ certificates
  • There are participation certificates for everyone who submits an entry with as little as one valid QSO - no excuses now!
