New YB Club Plaque now available for the 2023 SSB contest

The Oceania DX Contest committee is pleased to announce a late addition to the contest for 2023.

In line with our ongoing work to develop Indonesian interest in contesting, this year will feature the introduction of a new plaque supporting Indonesian club activity in the contest. Thanks to Karsono, YB0NDT, this new plaque will be awarded to the top entrant from an Indonesia club station (using callsign prefixes 7A – 7I) in the Phone Multiple-Operator Single-Transmitter category in the 2023 SSB contest.

We look forward to growing the number of Indonesian club stations that get together and participate in this event!

Report on 77th OCDX Contest – 2022 – Results Announced!

Congratulations to all the winners in the 2022 Oceania DX (OCDX) Contest and thanks to everyone who participated to make it the biggest OCDX party ever!

We had another brilliant turnout assisted by some excellent openings on the higher bands. We received a total of 1940 logs, consisting of 1133 Phone logs and 807 CW logs. This exceeds the 1908 logs received in 2021 and sets a new record.

Solar conditions were generally excellent except for a brief disruption from an X-class flare over the Phone weekend. The 10.7 cm solar flux peaked over 150 on both the Phone and CW weekends – the best we’ve seen since 2002! This meant that most intercontinental QSOs were on the 20M, 15M and 10M bands. 10M was finally open to all continents and many new records were set on this band. 40M activity was well down on recent years. Conditions on 160M and 80M were the poorest that we’ve seen for many years due to QRN from lightning storms along with some elevated geomagnetic activity over the CW weekend.

Fred KS7T sums it up with “10M being open makes this contest much more fun and it was open better than 15M. Love those 8k++ mile QSOs on any band!”

Matsunaga JS2MYR

It’s always encouraging to see newcomers joining in and having some – like Matsunaga JS2MYR who says “I’m a beginner on HF band. I’ve never connected with Australia before. I enjoyed this contest and was so excited. Thank you so much!”

Fred K3ZO (SK)

Fred K3ZO reported

“What a difference rising solar flux has made in the Oceania SSB contest.  In 2018-2021 it was mainly a 40M contest and I had to struggle to make 100 QSOs.  In 2019 I made exactly ONE QSO on 20M.  This year 20M was wide open to Australia and New Zealand at both the beginning and the end of the contest and I made exactly ONE HUNDRED QSOs on 20M and 220 QSOs overall! Last year I made 27 QSOs on 15 and they were all KH6s, VKs or ZLs. This year I made 47 QSOs on 15M and the first 28 of those QSOs were Indonesians.  10M last year? Forget about it – this year 10M was good for 36 QSOs!”

You can read Fred’s full report (here).

We are sad to report that this was also the last OCDX contest for Fred K3ZO as he became a SK earlier in 2023. Fred has been a regular entrant in the contest over the past 40 years and was also leader from North America in the Phone and CW Single Operator High power categories on many occasions.

Farewell Fred – we will miss your big signal on the bands and in our contest logs.

While most Oceania activity was from the more common countries (Australia, East Malaysia, Hawaii, Indonesia, New Zealand, and the Philippines) it was great to see an increase in the number of participants from some of the rarer Oceania countries such as Brunei Darussalam, Chatham Islands, Fiji, Guam, Mariana Islands, Marshall Islands, Samoa, and Vanuatu.

See the 2022 OCDX contest charts for a full analysis of the activity in the contest in 2022 and over recent years.

Indonesian Plaque Winners – 2022

It is also great to see the very high level of interest in the contest by amateurs in Indonesia. This year we again awarded a number of plaques specifically encouraging our YB friends to come and give contesting a go, and by all accounts it seems to be working!

This year we are pleased to present the following Indonesian specific awards:

YD0NHG Winner INDONESIA General Licence PH SO LP
(plaque presented to the Runner Up YC5LCZ under rule 12b)
Winner INDONESIA Advanced/Extra Licence PH SO 40M


Mirek Rozbicki VK6DXI Memorial Plaque 2022 Winner

Lastly we wish to congratulate Luca Babolin IK2PFL on winning the Mirek Rozbicki VK6DXI Memorial Plaque for 2023!

Note that plaques for the 2022 contest have been distributed in accordance with the new 12b rule introduced for the 2020 contest, i.e. if an entrant is eligible to receive multiple plaques in a hierarchy, they only receive the plaque for the highest level that they win. The plaque inscription will include the details of any lower-level plaque categories that they have won. The lower-level plaques are awarded to the runner-up entrants in those categories and the inscription on those plaques will state that they are being awarded to the runner-up.

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 postage of each plaque.


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 .


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 OCDX log checking reports page . Any entrant can enter their callsign 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 .


The 2023 Oceania DX contest will be held over the first two full weekends of October at the following dates and times:

  • Phone Section: 06:00 UTC Saturday 7 October to 06:00 UTC Sunday 8 October 2023
  • CW Section: 06:00 UTC Saturday 14 October to 06:00 UTC Sunday 15 October 2023

The 2023 Oceania DX Contest rules will be published on the OCDX Contest web site as soon as they are available.


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 hours 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 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 77th contest and made it such a huge success. We look forward to seeing you all again, along with more new entrants, in the 2023 pileups!

Report from Fred Laun K3ZO on 2022 OCDX Phone Contest

We are sad to report that 2022 was the last OCDX contest for Fred K3ZO as he became a SK earlier in 2023. Fred has been a regular entrant in the contest over the past 40 years and was also leader from North America in the Phone and CW Single Operator High power categories on many occasions. His report on his experience on the 2022 contest is inspiring to say the least, and so the committee wanted to honor Fred’s memory by reproducing it here for all to read.

Farewell Fred – we will miss your big signal on the bands and in our contest logs.

Fred K3ZO at a dinner in September 2022 with Potomac Valley Radio Club friends

What a difference rising solar flux has made in the Oceania SSB contest.  In 2018-2021 for me it was mainly a 40 meter contest and I had to struggle to Make 100 QSOs.  In 2019 I made exactly ONE QSO on 20 meters.  This year (2022) 20 Meters was wide open to Australia and New Zealand at both the beginning and the end of the contest and I made exactly ONE HUNDRED QSOs on 20 meters and 220 QSOs overall.

Last year (2021) I made 27 QSOs on 15 and they were all KH6s, VKs or ZLs. This year I made 47 QSOs on 15 and the first 28 of those QSOs were Indonesians.  Ten meters last year? Forget about it!  This year 10 meters was good for 36 QSOs.

I did make some improvements to the 10 meter 4-el dual-driven Quad at 78 feet.  Brand new coax and a dedicated in-line Ameritron antenna tuner so I can tune the quad for minimum SWR on either the SSB end of the band or the CW end of the band depending on the contest.  I was able to run QSOs to a limited extent; one-third of those QSOs called me, I had to S&P the others.

What surprised me was how long the 10 meter band remained open to VK and ZL.  My first QSOs were at just past 5 PM local time and the band was still wide open at 9 PM.

I was reminded about my good fortune in having bought W4QAW’s 8-element Telrex 15 meter Yagi when he tore his contest station down.  At 155 feet it is my highest antenna, and after 10 meters closed it carried me along until 10 PM.  I was able to work Indonesians up until that hour; even though they didn’t Move the S-meter at all they came right back to me when I called.  The number of

YBs has expanded in recent years, and while they are tough to work on 40 even When they are loud — due to local QRM from other YBs on that narrow band – on 15 they seem to hear very well.  While I was tuning through the 15 meter band looking for Oceania stations, I was hearing several of my friends from Thailand as well as plenty of JAs and the occasional BY, so the CQWW contests should be very interesting this year.
