A team of eight operators were active from Hiva Oa (OC-027) in the Marquesas Islands, November 6-19,

2019. The team made 31,000 QSOs to 136 DXCC countries.

The CanAm DX Group is a loosely organized team of individuals that has made a number of DXpeditions

over the last 15 years. The group has never made a tents-and-generators DXpedition. The emphasis

has instead been on relatively rare countries that are accessible by air.

The TX7T group included Robert Brandon K5PI, team leader; Madison Jones, W5MJ, who has been the

team leader in past years; Keith Witney VE7KW; Neil King VA7DX; Bob Feldtman W5RF; Bill Priakos

W5SJ; Bob Allphin K4UEE; and Didier Cadot F6BCW. This was Didier’s first DXpedition with the group,

although he worked with VE7KW on the TM100VIMY operation.

The Marquesas Islands are a group of 15 islands 1370 km northeast of Tahiti. The Marquesas Islands are

a separate DXCC entity but part of French Polynesia, which is an overseas collectivity of France. The

population of the Marquesas Islands is approximately 9300,

At the time of the DXpedition the Marquesas Islands were #59 on the Clublog Worldwide Most Wanted

List, and #28 for Europe.

The first challenge for any DXpedition is finding lodging and a place to operate. The team spent a

considerable amount of time looking for a beach location on the north side one of the four islands

served by Air Tahiti. In 2014, TX7G had operated from a beach location on the north side of Nuku Hiva,

but this family pension had closed. Available lodging was finally found on the south side of Hiva Oa,

near the town of Atuona. This was not a beach location and was on the south side of the island. It was

on the side of a hill. It had a clear view several kilometers down a valley to the north. About 1.5 km to

the northeast, a hill rose about 50 meters above the TX7T site. Much of the path to the northwest was

unfortunately blocked by a hill behind the operating location.

This terrain was not ideal, but F6BCW had operated as TX5EG with some success from this location in

2017. He said it was a quiet location, and he could offer advice on exactly where antennas might be

located. Didier was able to negotiate an agreement to use some additional land above the pension for

antennas. With this information, VE7KW developed an antenna plan that met the requirements of a

three-station operation.

One Hexbeam was used primarily for 12 and 20 meters and placed directly behind the pension.

A second, larger hexbeam for 10, 17, and 40 was placed on top of the hill above the pension.

A homebrew moxon for 15 and 30 was placed to the south of the pension.

A two-element vertical array for 40 (design by W4RNL) was deployed just below the pension. This

antenna could be switched from NE to SW (LP EU) and proved to be the most effective antenna for 40.

A two-element wire beam for 80M was placed from the top of the hill down to a point just above the

pension. This antenna is described in the June 2018 issue of QST.

A 160M inverted L was installed on an 18m fiberglass pole with two elevated radios. This was just above

the pension.

Three Elecraft K3 radios were used, with a KX3 as backup. Three Expert 1.3 and 1.5 amplifiers were

used, with a Juma PA1000 as backup. A list of 238 accessories, cables, tools, etc. was developed and

responsibility for these items was assigned to the team members. This included 650 meters of coax – all

of which was used!

Equipment donations were received from Expert Linears, DX Engineering, Radiosport headsets, Messi

and Paoloni, Gigaparts, and Quicksilver Radio.

The team had hoped to ship some equipment in advance, but it was too complex to ship items from four

locations in the US/Canada for consolidation by an agent in Los Angeles for shipping to Tahiti. Almost all

equipment was carried as passenger luggage.

The team met in Tahiti over four days and operated with limited antennas from Mahina. The team

logged approximately 1500 QSOs and operated one night on 80M and one night on 160M. QSL via the

operator’s home call.

The team discovered that the VP6R team was in Tahiti for one night on their way home, and we

arranged to have dinner with them. It was fun, and we got lots of good information about their

experiences.

F6BCW left for the Marquesas on November 3, and the rest of the team flew to Hiva Oa on November 6.

The lodging at Pension Kanahau was modest but very comfortable. Tania was a great host and an

outstanding cook. The Marquesas Islands is the fruit and vegetable garden for much of French

Polynesia, and we enjoyed a nice variety. Raw fish is a staple in all of French Polynesia, and the entire

team enjoyed it.

The pileups were very good, but most signals were not very strong. We made a special effort to work

Europe stations, and they were especially weak. We found CW and FT8 to be the best modes given the

conditions, although we used SSB when conditions were best.

We had no radio or amplifier failures and almost no interference between stations. We continued to

work on the antennas, however, throughout the DXpedition. We deployed a pennant receive antenna

and later a short beverage. We raised the large hexbeam several feet, which was difficult with the wind

on top of the hill. We modified the 160 from an inverted L to a tee-top. We briefly used a 17M vertical

dipole. We deployed a two-element delta loop array for 20M. All this was a challenge in the hot sun, on

the steep hillside, and with only two team members under age 70.

We met our goal of 30,000 QSOs and are happy that 13% of our QSOs were to Europe. Thanks to

everyone for QRX during the limited EU openings.

CW was very productive, with more than 51% of the QSOs.

FT8 and FT4 were also important, with 35% of the QSOs. FT8 DXpedition (Fox-Hound) mode worked

well at times, but we struggled with the same software issues as VP6R. It seemed that many stations did

not have a correct FT8 WSJT-X Hound configuration, so we sometimes used FT4. We also made some

QSOs in standard FT8, but that mode is very slow for a DXpedition. We would encourage all FT8

operators to use RS232 to connect the computer to the radio, and enable Split (Rig or Fake It). More

information about WSJT-X DXpedition mode in several languages is here.

After the TX7T operation, FO/F6BCW remained on Hiva Oa for a week. QSL via F6BCW.

FO/K5PI operated from Fakarava (French Polynesia, OC-066) for about a week while enjoying some

scuba diving. QSL via K5PI.

TX7T…….Where are the Marquesas???

untitled

CQ de TX7T

In order to validate our different logos, presentations, drawings, and other creations to enhance TX7T, I just wanted to bring you a point of view, both philosophical and cultural on the Marquesas I have known since 1974.

99% of the world's population knows very little about geography and almost everyone does not know where the Marquesas are located and that they are French islands.
Ham radio is more familiar with geography, but their knowledge is still quite limited.
A friend of mine, a university science teacher, believed that Bora Bora was American. A French friend, Ham radio, DX'man, thought the same thing.
Bora Bora is located in the Leeward Islands Archipelago, it has been French since 1888.
It was loaned to the USA throughout the Pacific War as a resting place for GIs.This is what made it famous, and makes us think that this island is American.

Many Ham radio operators do not know how to point their antennas in the right direction for the Marquesas.

The Marquesas:
They were discovered and populated by Polynesians, Maori from Samoa and Tonga between less than 150 years and more than 100 years after Jesus Christ.
This is the reason for the different language of Tahitian, the customs that are very similar to those of Tonga, such as the famous haka.
Between 400 and 800 AD, the Marquisans were the first peoples to arrive on Rapa Nui, the Easter island.
In 1595, Alvaro de Mendana, a Spanish navigator, was the first Westerner to setfoot on Fatu Hiva and Tahuata.
Two centuries later, in 1793, the Frenchman Étienne MARCHAND took possession of the Marquesas on behalf of France, and in 1842, Aubert Du Petit Thouars integrated the Archipelago into the French Establishments of Oceania.
Nuku Hiva, the administrative centre of the Marquesas, is located 1400 km fromTahiti.

The whole archipelago has a little less than 1000 Km² of surface area and has alittle less than 10,000 inhabitants, i. e. a population of 10 inhabitants per km². . . .
The last radio amateur to have lived in the Marquesasin Hiva Oa, is my friend Patrick FO5QS. That was in 2015. Now FO5QS live in Huahine.

If you are a stranger to the Marquesas, you must be Paul GAUGUIN, a famous French painter (1848 / 1903) or Jaques BREL(1929 / 1978), a famous Belgian singer to settle permanently and live fully the Marquesas. . .
To know a little more about it, 2 internet links that I recommend you.
