PHONE Contest: 08:00 UTC Saturday 5 October to 08:00 UTC Sunday 6 October 2019
CW Contest: 08:00 UTC Saturday 12 October to 08:00 UTC Sunday 13 October 2019
The aim of the contest is to promote HF contacts with stations in the Oceania region, i.e., 9M6, DU, KH6, VK, ZL, YB, Pacific Islands and all other Oceania entities identified in the ARRL list of DXCC entities.
The object is for:
The bands that can be used are 160M, 80M, 40M, 20M, 15M and 10M (no WARC bands).
RS(T) report plus a progressive contact serial number starting at 001 and incrementing by one for each contact. M2 and MM entries are to use a separate serial number starting at 001 for each band. If the station worked does not send a serial number for the contest, then the received number is to be logged as 001.
The multiplier is the number of different valid prefixes worked. Note that the same prefix may be counted once on each band for multiplier credit.
The prefix is the letter/numeral combination which forms the first part of the amateur call.
Examples of valid prefixes are N8, W8, WD8, HG1, HG19, KC2, OE2, OE25, LY1000, etc. Any difference in the numbering, lettering, or order of same shall count as a separate prefix.
A station operating from a DXCC country different from that indicated by its call sign is required to sign portable. The portable prefix must be an authorized prefix of the country/call area of operation. In cases of portable operation, the portable designator will then become the prefix. Example: N8BJQ operating from Wake Island would sign N8BJQ/KH9 or N8BJQ/NH9. KH6XXX operating from Ohio must use an authorized prefix for the U.S. 8th district (/W8, /AD8, etc.). Portable designators without numbers will be assigned a zero (0) after the second letter of the portable designator to form the prefix. Example: PA/N8BJQ gives the prefix PA0.
All calls without numbers will be assigned a zero (0) after the first two letters to form the prefix. Example: XEFTJW would count as XE0.
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 encouraged to participate. Prefixes must be assigned by the licensing authority of the country of operation.
Each QSO is credited twenty points on 160M; ten points on 80M; five points on 40M; one point on 20M; two points on 15M; and three points on 10M. Note that the same station may only be counted once on each band for contact points.
The final score is the sum of the Contact Points multiplied by the Multiplier (the total number of prefixes worked on all bands, noting that the same prefix can be counted once on each band).
The trophies and plaques to be awarded are listed here.
Certificates will be awarded to the top scoring station in each category listed under Section 7 for each IARU WAC continent and each country. A participation certificate will also be awarded to every station that makes at least one valid QSO. Participation certificates are not awarded to stations that submit check logs.
The certificates will be made available on the contest web site at http://www.b4h.net/ocdx/certificates.php for entrants to download and print at their convenience.
Awards may be withdrawn or added at any time, and at the discretion of the Contest Committee. Refer to the Oceania DX Contest web site at www.oceaniadxcontest.com for the latest information about contest awards.
Transmitting entries are to submit a log showing the following details for each contact - date and time in UTC, frequency (or band), call sign of the station worked, RS(T) and serial number sent, RS(T) and serial number received. All QSOs must be submitted in date/time order. A log without all required information may be reclassified as a Check Log. All duplicate contacts must be shown - DO NOT delete duplicate contacts. No penalty will be applied for showing duplicate contacts.
SWL entries are to submit a log showing the following details for each contact - date and time in UTC, frequency (or band), call sign of the station 'heard', call sign of the station 'being worked' by the 'heard' station, and the RS(T) and serial number sent by the 'heard' station. The same call sign for the station 'being worked' may appear only once in any group of 3 consecutive entries on the same band. Note: in the case of non-Oceania SWL entries, only Oceania call signs should appear in the 'station heard' column.
Electronic logs are preferred and are mandatory for stations logging more than 50 contacts.
Electronic logs are to be submitted in Cabrillo format as specified at http://wwrof.org/cabrillo/ and supported by most popular logging programs. The Cabrillo log file must include an accurately completed header (containing the summary information) and the QSO log data. Failure to fill out the header correctly can result in the entry being placed in the wrong category or reclassified as a Check Log. See www.oceaniadxcontest.com for the latest information on the Cabrillo log format requirements.
The log file name is to be in the form callsign.log, for example, if ZL2WB submits a log file - then it should be named zl2wb.log.
Submit your Cabrillo log file using the on-line submission form on the web site at www.oceaniadxcontest.com. The web form will check the information in your log for any obvious errors and ask you to correct and resubmit the log if any such errors are found. Otherwise, the web form will acknowledge the successful receipt of your log, and a message confirming receipt (along with a copy of the received log) will also be emailed to you. Please contact the Contest Committee at email@example.com if you are experiencing any difficulties in submitting your log.
Entrants using paper logging, or logging software that does not produce a Cabrillo file, are encouraged to use the on-line forms at http://www.b4h.net/cabforms/ to create and submit a Cabrillo file.
Electronic Logs are preferred (see Rule 14 above) but if this is not possible then paper logs in the Oceania DX Contest format may be submitted, provided they contain less than 50 contacts. Each paper log is to be accompanied by a summary sheet that clearly states:
Official log and summary sheets can be downloaded from the Oceania DX Contest web site at www.oceaniadxcontest.com. If you do not have access to the official forms then you may make your own in accordance with the general requirements outlined above and in Section 13.
Paper logs are to be are to be posted to: Oceania DX Contest, c/o PO Box 21088, Little Lonsdale Street, Victoria 8011, Australia. Airmail should be used when submitting a log from outside VK or ZL.
All logs must be submitted on-line or postmarked NO LATER than 31 October 2019. A listing of all logs received on-line will be posted on the Oceania DX Contest web site at www.oceaniadxcontest.com.
Violation of amateur radio regulations in the country of the contestant or the rules of the contest; unsportsmanlike conduct; or taking credit for excessive unverifiable QSOs or multipliers will be deemed sufficient cause for disqualification. Incorrectly logged calls will be counted as unverifiable contacts. Any entrant that uses means, other than contacts on the permitted bands and modes, to SOLICIT, ARRANGE, or CONFIRM any contacts in the contest is unsportsmanlike and the entry will be subject to disqualification.
Although no signed declaration is required, by submitting a log you are deemed to have agreed that: 1) you have read and understood the rules of the contest and agree to be bound by them, as well as all rules and regulations of your country which pertain to amateur radio; 2) your log entry may be made available for public viewing; and 3) all actions and decisions of the Oceania DX Contest Committee are official and final.
The latest information about the contest is published on the Oceania DX Contest web site at www.oceaniadxcontest.com. Any queries should be emailed to firstname.lastname@example.org or posted to Oceania DX Contest Committee, c/o PO Box 21088, Little Lonsdale Street, Victoria 8011, Australia.
Future OCDX dates for your diary:
In 2001 the start time for the contest was brought forward by two hours from 10:00 UTC to 08:00 UTC so ZL and other western Oceania stations could finish at a more reasonable time on the Sunday evening. Some VK entrants are now asking that we bring the contest period further forward. The main reason cited is that more stations are operating from remote locations to get away from the manmade noise in urban areas and these stations wish to finish earlier so they have more time on Sunday afternoon to pack up and travel home in daylight.
The contest committee considers that it may be possible to bring the contest further forward, but by no more than 2 hours, i.e. to start and finish at 06:00 UTC. A start time earlier than 06:00 UTC would not be appropriate because it would require Pacific island stations immediately east of the international dateline (e.g. Niue, American Samoa and Tokelau) to begin too early on their Friday afternoon. Any earlier would also start to seriously eat into the time available for YB, VK6 and other western Oceania stations to set up in daylight on the Saturday, especially if they are travelling to remote locations.
Propagation factors also need to be considered. Moving the contest forward to 06:00 UTC would result in more Oceania stations starting and finishing in daylight hours when DX propagation is less favourable and limited to the higher bands. This would make a slower start and finish for a greater proportion of entrants and could result in fewer entrants operating the full 24 hours. The earlier finish also means that some Oceania and European stations would no longer be able to rely on having a second opportunity to work each other via the long path at the end of the contest. This could have a noticeable impact on their scores if the long path opening at the start of the contest is in poor shape.
The committee will make a decision on this matter after the 2019 contest. In the meantime, the committee is interested in receiving the views of entrants on the pros and cons of moving the start and finish times forward by 2 hours to 06:00 UTC for the 2020 contest. Please email your views, along with reasons, to the committee at email@example.com.
