Congratulations to our 2024 Oceania DX Contest Winners

Congratulations to all the winners
in the 2024 Oceania DX Contest
and thanks to everyone who participated to
help make it another memorable Oceania DX party!

 

The average solar flux over the Phone and CW weekends reached 271 and 204 respectively – by far the highest values observed since we started monitoring space weather conditions for the contest in 2001. The high solar flux provided good conditions for the Phone section but conditions were much poorer in the CW section due to major geomagnetic storm activity that caused the Ap index to peak as high as 112.

The elevated solar flux meant that most of the action was on the 10M and 15M bands. Many new continent and country records were achieved on these bands. For example, Nick VK9DX logged an impressive total of 2,472 QSOs on 10M to set a new record for Oceania in the Phone SO 10M HP category, as well as achieving the second highest score in Oceania. JA7OWD (Eijirou Takahira) set a new world record in the Phone SO 10M HP category.

Gary W0BF says “10M was like night and day in the Phone section! Weak signals the day before but on the day of the contest signals were so loud they almost broke my speaker!!”

The 20M and lower bands were in much poorer shape. In his CW log Fred KS7T reported “A big decline in the prop here this year from the CMEs with ZM1A being the only station in Oceania I could hear on 20M until WH7T showed up near the end of the contest”. The number of intercontinental QSOs on the 160M, 80M and 40M bands was the lowest we’ve seen since 2021. Almost all of the 160M QSOs were between Oceania stations – there were no cross checked 160M intercontinental QSOs.

It was again encouraging to see many first-time entrants having a go in the contest. Joe VK4IAG entered the Phone section and says “My first contest. Great fun even on low power and I realised that the airwaves aren’t dead and there are heaps of DX contacts to be made, even on low power.”

Logs Received

We received a total of 1672 logs this year, consisting of

  • 1052 Phone logs
  • 620 CW logs.

There was a reduction in the number of logs from Indonesia in the Phone section but this was largely offset by a record number of logs received from North America and South America.

There was also a reduction in the number of CW logs, across all continents. The main cause appears to have been the depressed conditions due to the geomagnetic storm activity.

As usual, most of the Oceania activity was from the more common entities, i.e. Australia, East Malaysia, Hawaii, Indonesia, New Zealand, and the Philippines. Indonesia had the largest number of entries in the Phone section and Australia had the largest number of entries in the CW section.

There was also activity from rarer Oceania DX entities including Eastern Kiribati, Fiji, French Polynesia, the Marshall Islands, New Caledonia, Norfolk Island and Samoa. We appreciate the efforts of the operators who activated these locations as they are important for attracting interest in the contest.

Outside Oceania, the continent with the most entries in both the Phone and CW sections was Europe. The country with the highest number of entries was Japan, followed by the United Sates, European Russia and then Germany.

See the 2024 Oceania DX contest charts  for more analysis of the activity in the 2024 event and the trends over time.

2024 CERTIFICATES

Certificates are awarded to the top scoring station in each category for each continent and country. Additionally, each station that took part in the contest and made one or more valid QSOs, is awarded a participation certificate showing the number of valid QSOs made. The certificates are available online for downloading and printing from the Certificates page.

2024 LOG CHECKING REPORTS

A log checking report is produced for each entry in the contest (except SWL entries). This report provides details about the calculation of the final score including identifying any QSOs that are duplicates (no penalty), calls that are copied incorrectly, exchanges that are copied incorrectly, QSOs that are not in the other log, and calls that are unique and not in other logs (no penalty).

Entrants can obtain their reports from the OceaniaDX log checking reports page. Any entrant can enter their call-sign on this page to have a copy of the relevant report sent to the email address used to submit their log. Anyone having difficulty downloading the report (e.g. due to a change in their email address) should contact the contest committee at info@Oceaniadxcontest.com .

Sponsorship

The ongoing sponsorship of plaques is important for maintaining and growing interest in the contest. New sponsorship offers are always welcome and anyone who is interested in becoming a sponsor should contact the Contest Committee. The cost of sponsoring a plaque is AUD 55.00 per annum to cover the expenses associated with the manufacture and delivery of each plaque.

ACKNOWLEDGMENTS

The successful running of the OCDX contest is a large team effort involving contributions from around the world. The log uploading, log checking and certificate production processes are now largely automated, but committee members and others still contribute many days of effort each year to manage these processes along with writing up and publishing of the annual results, administering the sponsorship and distribution of plaques, and promoting the contest.

The ongoing support of the following individuals and organisations is acknowledged and greatly appreciated:

  • Ken K1EA for supplying and supporting our log checking software.
  • Mike ZL1AXG for hosting the OCDX Contest domain name and email server.
  • The Amateur Radio Experimenters Group (AREG) for hosting our web site.
  • Bruce WA7BNM for providing and managing the web portal for the uploading of logs, delivering certificates and log checking reports, and the provision of his on-line web form for converting non-Cabrillo logs to Cabrillo format.
  • All the plaque sponsors.

Finally, and most importantly, thank you again to everyone who took part in the 79th contest and made it such a success. We look forward to seeing you all again, along with more new entrants, in the 2025 pileups!
