Unique lecture about TX5K on SI9AM

The last six years DD2CW/Jef and ON6UQ/Marcel has rented SI9AM and worked CQ WW SSB Contest from SI9AM. This year ONL741/Dirk and ON7TQ/Roger took the opportunity to to with them. For ONL741/Dirk it was the second time but for ON7TQ/Roger it was the first time to rent SI9AM.

During the spring, we asked Jef, who was one of the operators on the DX peditionen TX5K to Clipperton Island in February/March this year, if he wanted to give a lecture about TX5K. " Of course. Best for us is on Holmstagården the day before the CQ WW Contest, he replied".

Arrival to SI9AM

Already on Wednesday evening October 23 the guys arrived to Utanede and began to work from SI9AM.

Friday evening October 25

On Friday evening at 19:00 local time, it was 18 radio amateurs from Örnsköldsvik, Kramfors, Östersund and Sundsvall who had travelled to Holmstagården to listen to DD2CW/Jef. All the hams had travelled a long way to hear the lecture. Some of the hams had travelled 120 Swedish kilometers one way to Utanede. It became 240 Swedish kilometers the same evening, so there were big interest hear about the preparations for the DX-pedition, the travelling to Clipperton , building up the camp, all the amateur radio contacts and then how to dismount the camp och the trip home and of course to see a lot of pictures.

Silent key

Our president SM3CVM Lars Aronsson died after a long illness on October 22. This evening was therefore initiated with a minute of silence for SM3CVM Lars.


The DXpeditionen to Clipperton Island consisted of 24 radio amateurs and five scientists / journalists. It was a huge preparation work . The DX team had a chartered boat , Shogun, who took half the team and all the material from San Diego to Cabo San Lucas where the rest of the team boarded the ship continued the trip to Clipperton Island.

The landing on Clipperton was not easy. Shogun had to anchor a bit off and everything has to be transported to the island in a small boat. It took a lot of time to move all the people and the equipment  to the island and it was not quite risk free. There was a huge amount of materials needed for the stay on the island.

On the island all helped with unpacking all the equipment that was clearly packed in different boxes, to put up all masts and to build up the camp. It was a tuff work and sometimes the temperature was up to 55 degrees.

All food was cooked on the boat Shogun and transported once a day to the island. But in case of stormy weather, when to boad could not land on the island, they must have extra food at the camp.

The radio operating from the island could be followed from their website where all the logged QSOs could be followed in real time.  For those who worked TX5K there no speculation if they was in the log or not.

The DX peditionen was shut down a little early because of an approaching storm. It was a hard work in the heat to take down all the masts, dismantle the camp, pack everything into boxes and clean up. But through an efficient teamwork Shogun and the expedition could leave the island before the storm came.

The trip started on February 18 and ended on March 18. The radio team logged 113,601 contacts, and the science team made several discoveries. No damage was done to the island or wildlife; the campsite was left cleaner than before the expedition.

How did they manage in the CQ WW SSB contest ?

In the CQ WW Contest on SSB the guys worked 3,040 QSOs and got about two million points, which is an all-time high on SI9AM.

They have already booked in for next CQ WW SSB on SI9AM.


A very big thank to you Jef, it very fascinating to take part of your experience of DX peditionen and see all the pictures. There were many questions which you answered and some of us who listened had wished that could have joined to DX-pedition to Clipperton Island.

We hope you will participate in more DX peditions and let us heare about them.

Facts about Clipperton Island (from Wikipedia)

Clipperton Island is an uninhabited 9 km2 (3.5 sq mi) coral atoll in the eastern Pacific Ocean, south-west of Mexico, west of Costa Rica and 2420 km north-west of Galapagos Islands, Ecuador. It is an overseas possession of France under direct authority of the Minister of Overseas France.

It is low-lying and largely barren, save for scattered grasses and a few clumps of coconut palms. A small volcanic outcrop rising to 29 m (95 ft) on its south-east side is referred to as "Clipperton Rock".

Clipperton is about 945 km (587 mi; 510 nmi) south-east of Socorro Island in the Revillagigedo Archipelago, the nearest land. Its ring-shaped atoll completely encloses a stagnant freshwater lagoon, and is 12 km (7.5 mi) in circumference. 

It has a tropical oceanic climate, with average temperatures of 20–32 °C (68–90 °F). The rainy season occurs from May to October, when it is subject to tropical storms and hurricanes.

The island has long been an attractive destination for amateur radio groups, due to its remoteness, difficulty of landing, permit requirements, romantic history, and interesting environment. While some radio operation was done ancillary to other expeditions, major DXpeditions include FO0XB (1978), FO0XX (1985), FO0CI (1992), FO0AAA (2000), and TX5C (2008).
