A35JT OC-049 Tonga

Final antenna packing lists are being drawn up today and at this stage I hope to also include an inverted L for 160m. Having tried to operate 160m at home recently I decided I was silly not to give it a go in a much more RF quiet location, and with a better antenna with a better ground plane. I will try and pay attention in particular to my morning grey-line into Europe, but will also do some activity during the NA morning grey-line as well.

Only 4 days to go before we depart Adelaide and head down to IOTA OC-139. See you on the air!

The logs from our Tonga DXpedition last year have now been posted to QRZ.com. We hope this will provide users of that platform with much needed confirmations!

For those wanting SSB contact with A35JT please look out on the bands for us operating the last 24 hours of the expedition in the Oceania DX contest. We hope to run all contest bands as a Multi-One station (160/80/40/20/15/10). Other activity will also run on Station 2 as either FT8 or CW outside of the contest. Statoon 2 is closing tomorrow lunchtime (Sunday around 0000z on the 6th of October). We will also be tearing down the 160m antenna and the 80m antenna Sunday morning as well as the 40m 4-square antenna. 30m will end at lunchtime also leaving only the SSB station remaining after this time. A huge thanks to everyone who has worked us over the past 2 weeks.

Live Stream Logging Disabled During the contest

To make it fair the team has disabled the LiveStream logging during the Oceania DX Contest. The final log upload will occur after the contest (and due to teardown operations may not be completed until we land in Auckland New Zealand on Tuesday).

Since we started here at A35JT we have been working 160m as much as we can on ours, NAs and EUs greylines. So far we have had 209 CW QSOs, 246 FT8 QSOs and 4 RTTY QSOs (yes you read that right – we were mad enough to have some fun on RTTY on 160m).

How did we do it? With 500W or less and a 12m high inverted L antenna built on a Spiderbeam pole out of parts from a CrankIR 80m extension kit. This little antenna has performed wildly beyond our expectations. Hats off in particular to Steve VK5SFA who worked on the design and to the operating team for this little creation.

It was an eventful day here in Tonga. The team was in the radio room working away when Oly VK5XDX says “can anyone hear crackling”. They look outside and see an approaching scrub fire. Very quickly the fire brigade was called, the antennas dropped to make way for the tender and preparations were made to warn off ember attack. As the team are all from Australia thoughts immediately turned to the worst, given VK’s history of bush fires. This however was very different as there was a grassy paddock the other side of the green tropical foliage next to our accommodation blocks. When the fire reached that it stopped and burned itself out.

It was made all the more stressful as Grant VK5GR (team leader) was off site picking up his family from the airport plus food supplies for the crew and couldnt be reached. He returned to the site in disarray and a lot of very nervous people at the point of the fire’s closest approach.

In hindsight the threat was probably pretty low given the way the fire was burning, but it set the team on edge for sure. We are all safe and well now and returning to normal operations. The only antenna that probably wont go back up is the 6m beam (we had planned on ending the EME sessions as of Sunday anyway.) the 30m 4sq and 40m 4sq are restored as is the HexBeam. We will see you on the air!

Emergency is over, everyone is safe and no damage done. The antennas are back in the air and operations will resume shortly https://t.co/xYn4mSJ2ko

Looks like there is a logging problem with WSJT-X in fox-hound mode. Don't panic we are working on extracting QSOs out of the raw text logs. @A35JT_2019 #hamradio #softwareisshit pic.twitter.com/HzbK3RiyOK

The A35JT DXPedition team has revised our frequency plan.  It is going to be very crowded on the bands with up to 5 concurrent expeditions. We have reviewed all available data and have made some changes accordingly. Please see the latest information here:

On 6m EME look for us on: 50.203MHz

The team will monitor the DXClusters if possible and will further adapt the plan according to band usage. See you on air in about 4 days time!

We had some great news today. Our antenna shipment has cleared customs and quarantine processes and is ready for us to collect on Monday! A huge thank you to Mary and all of the staff at Pacific Forum Line in Nuku’alofa as well as to the good folk in the Revenue and Customs Ministry who helped facilitate this on our behalf. We look forward to thanking you all in person for your help and support next week! Thank you also to Mala at Tayper Freight Forwarders back in Australia for handling this end of the shipment.

Meanwhile, back in Australia, two of the stations are packed into their travel cases and the third is being finalised now. The low band antennas and Spiderbeam 12m fibreglass pole were also packed today (they are flying in with us as luggage). The team is now getting excited to get out there and get on the air!
