Z23MD Zimbabwe expedition

Tous les ans depuis 2011, le Méditerranéo Dx Club (le pendant Italien de notre CDXC) organise une expédition dx. Cette année c’est au Zimbabwe que 16 OM’s de 8 nationalités différentes  (6 Italiens, IZ8CCW, I2VGW, IZ2GNQ, IK5BOH, IZ4UEZ, IK4QJF – 2 Belges, ON4LO, ON7RN – 2 Polonais, SP6EQZ, SP3DOI – 2 Allemands, DL6KVA, DJ5IW – 1 Roumain, YO8WW – 1 Américain, KO8SCA – 1 Autrichien, OE3JAG et 1 Français, F5EOT), ont trafiqué avec l’indicatif Z23MD.

Comme chaque année, le rendez-vous est donné à Milan. Les premiers arrivés auront droit à la traditionnelle « Pasta Partie » offerte par le radio club de Busto-Arizo, IQ2VA. Je n’ai pu y participer, mon avion n’arrivant qu’ en début d’après-midi à Malpensa Airport. Merci à Roberta, l’Yl de Gabriele, I2GVW, qui a pensé à ceux qui comme moi sont arrivés au dernier moment en leur apportant un petit bout du fameux gâteau clôturant le repas.


Il est 21h15 quand commence le long périple vers Harare la capitale du Zimbabwe où nous sommes arrivés le lendemain à 12h30, heure locale, après 2 escales, à Rome et à Addis-Abeba. Ce n’est que 2h30 plus tard, après les formalités de contrôle de police et de douane, qu’un premier groupe ainsi que tout le matériel partira en direction du Resort devant nous accueillir. Il n’est pas très loin de l’aéroport, une douzaine de km, mais le deuxième groupe dont je fais partie, y arrivera plus d’une heure plus tard. Le trajet d’environ 20mn, confirmera que nous sommes dans un pays pauvre. Si les routes à proximité de l’aéroport sont en bon état, très vite nous empruntons des pistes en latérite, avec trous et bosses …

La nuit arrivant tôt sous ces latitudes, nous avons juste le temps de décider de l’implantation des antennes. Il est 7h quand tout le monde se retrouve pour participer aux différents travaux. Avec Éric, ON7RN, François, ON4LO et Karl, OE3JAG nous formons le groupe pour monter les Spiderbeams. Le montage des différentes antennes se poursuivra toute la journée, mais les premiers QSO’s furent effectués vers 14h.Les 2 stations CW utiliseront 2 multi bandes, une Spiderbeam avec extension 40m et une HexBeam avec le 30m, une verticale 80m et une 160m. Des béverages furent tendues les jours suivants. Le RTTY avait une Spiderbeam 5 bandes avec une extension 30m et a partagé le 4X4 40m et la verticale 80m avec les stations SSB qui possédaient chacune leur propre Spiderbeam. Une K9AY fut montée pour faciliter la rx sur les bandes basses. Le FT8 utilisera sa petite antenne cadre ou les antennes libres.

Lors de leur journée libre, les uns ont choisi de visiter Harare la capitale; d’autres iront faire un safari dans la savane environnante; quelques-uns partiront voir les chutes Victoria situées sur le fleuve Zambèze à la frontière entre la Zambie et le Zimbabwe.

Près de 50.000 QSO’s furent effectués et ce malgré les orages et surtout les intempestives coupures de courant. Une, dura plus de 5h. L’accès au groupe électrogène de secours nous était impossible et interdit. A chaque coupure, il fallait appeler les propriétaires. Eux seuls avaient les clefs. Le temps que l’un deux se prépare (ils ont plus de 80ans ) , arrive à pieds depuis leur maison située a quelques centaines de mètres, un temps relativement long s’écoulait avant que le groupe ne démarre. Si les coupures étaient trop longues ou répétitives on dépassait le quota de carburant que ces derniers avaient inclus dans le forfait et nous devions attendre comme la fois ou l’attente dura plus de 5h.

Comme toujours, à la fin de toute expédition, une seule question se pose :

Where do we go next ?

A35EU Tonga expedition

                                         The kingdom of Tonga 2018
                                          A35EU by Ronald PA3EWP

How did this adventure start?
During a few beers during the Hamfest in Friedrichshafen we were talking about our next
destination.
We mentioned a few destinations in the Pacific. Personally, I don’t like to go twice to the same
country. A few destinations were out of our scope because of the cost and the difficulty to go to this
DXCC country. Frank DL4KQ mentioned Myanmar and everybody thought that was a great idea.
From July to half September we have been working on this destination, Frank did most of the work
because he had some contacts in Myanmar. He also flew to Myanmar for some arrangements with
the local government. Everything seems fine, but after 1 month back home, we still didn’t receive the
official papers. We wanted to go to Myanmar in October, so only a few weeks left to organize this
trip. We started to look for a backup plan. At the Hamfest we talked about Tonga as one of the
destinations. This is an easy place to activate, a lot of tourists go there, daily flights and a license is
also no problem. Tonga is not so high on the most wanted list, but for Europe still interesting. Within
2 weeks nearly everything (license, location, flights) was organized. So, we were ready for the
following step. End September we decided to postpone Myanmar and focus on Tonga.
Only 3 operators Tom GM4FDM, Martin PA4WM and Ronald PA3EWP wanted to go to Tonga.
We needed a fourth operator, soon this place was filled by Pat EI5IX.
The team was ready to go for a new adventure.

The Kingdom of Tonga
Tonga, is a Polynesian country and archipelago comprising 169 islands, of which 36 are inhabited.
The total surface area is about 750 square kilometers (290 sq. miles) scattered over 700,000 square
kilometers of the southern Pacific Ocean. The sovereign state has a population of approx. 100,000
people of whom 70% reside on the main island of Tongatapu.
The Tongan people first encountered Europeans in 1616 when the Dutch vessel Eendracht, captained
by Willem Schouten, made a short visit to trade. Later came other Dutch explorers, including Jacob
Le Maire (who called on the northern island of Niuatoputapu); and in 1643 Abel Tasman (who visited
Tongatapu and Haʻapai). Later noteworthy European visitors included James Cook (Royal Navy) in
1773, 1774, and 1777.
Tonga became independent in 1970 but is still a part of the commonwealth of nations.
Location on the Island
We found a nice location on the western part of the main Island. A previous Scottish DXpedition used
this QTH also, they gave us a lot of useful information. It was possible to setup the antennas the
border of the beach. On the beach itself was impossible because it was used also by other visitors.
The beach resort Heilala at Kanokupolu is located at the Ha’atafu beach. Because of the low season
we got card blanche to setup our antennas, we had only to take care of not disturbing the few other
guests.

Big challenge
Our biggest challenge would be the low sunspots. Nearly at the bottom of this sunspot cycle it would
be a challenge working Europe. Looking at the propagation prediction programs it would be possible
to work western Europe only on 20, 30 and 40 meter. But with weak signals. So, the challenge
became bigger. We new that every additional dB of gain would be very helpful. We decided to make
VDA’s for 17, 20 and 30 meter. Martin with help from Jan PA4JJ and Henk PA3GCV build the VDA’s
and the other wire antennas. They did a great job!

Travel to the Kingdom Tonga
It would be a long journey to travel to our destination. The team meeting-point would be Doha in
Qatar. Tom flew from Edinburgh, Pat from London and Martin and I from Amsterdam. We left
Tuesday 23 November for a 6-hour flight to Doha. Pat joined us a one hour after we arrived. We
received a message that Tom had a challenge. His plain was broken and could not leave Scotland.
This would be a challenge to catch his connection flights. When we boarded our plane to Auckland,
we received a message that his delay was 5 hours and maybe we would meet him in Auckland. For
the next 17 hours it would be quiet without any info from Tom. This is the second longest flight at
this moment, and we can say that is long! We arrived in Auckland and heard that Tom would leave
Doha in a few hours, so he would arrive only 1 day later at Tonga.
We had still 11 hours transit time in Auckland before our next flight. We put all our luggage in a
storage room and went by taxi to Auckland city, had a nice short walk and a visit at the sky-tower to
overview Auckland from 220m height. After a lunch we went back to the airport for our last part of
the trip to Tonga. This flight was only 2 1/2 hours. We arrived Tonga airport around 19.30 local time.
After collecting our luggage and a nearly 1-hour drive, we arrived at 21.30 at the resort Heilala.
Antenna setup
Early next morning, after breakfast we started assembling our antennas. We would focus on 17, 20,
30 and 40 meters for the first day. We soon noticed that we would have a challenge with the coaxcables. We brought approximately 500 meter of coax-cable with us. From the shack to the beach was
circa 100 meters.
Around noon I had to quit for meeting Tom at the airport. He arrived around 13.00. From the airport
we went to the Telecommunication office to collect our license.
We already had a few times contact with Officer of Telecommunication by email and phone about
the license. He had added the possibility to operate 60m band, we were very pleased with this
extension. For many or maybe everyone it would be a new DXCC on 60m. After leaving the office we
went shopping and back to the resort.
Martin and Pat were ready with the 17 and 20-meter VDA, the 30m VDA had only to be erected. We
needed 4 men to finish this job. The 40-meter vertical was also ready to use.
The next day we would finish the other antennas, 10/12/15m multiband vertical, 80 meter vertical.
For RX we used a DHDL antenna. We were waiting for a local guy which would climb into a 17m high
palm tree to make a rope on top of it for the 160m vertical.
After 2 days we decided not to wait longer and started to throw a rope over a palm tree and do the
job our self. We chose a palm tree approx. 12-meter-high for 160m and another palm tree for 60
meters. A few hours later both antennas were ready for use. The antenna farm was completed.
Luckily there were not many other guests, so we could use all the space we needed for our antennas.
Equipment:
We had 3 complete stations operational, one radio was for spare. Some hours of the day we
operated 3 stations simultaneously. We were using bandpass filters between radio and amplifier. Logging was done with WIN-test and WSJT-X. The computers were wireless networked. We used the Microkeyer MK2 as interface between radio and computer. There was a good internet connection, so we uploaded on daily basis our log to clublog.

Operating and propagation
All operators are mixed mode operators, everyone had his preferred mode. We focused on the main
modes CW, SSB and RTTY. Due bad propagation most of the QSO’s were in CW. We switched a lot
from mode. We noticed that due bad propagation we were forced to use FT8. There was a high
demand for this mode. Searching the bands, no activity on the band only on the FT8 frequencies (we
hope this will change quickly).
During the morning hours there was not much propagation at all, so we did some site seeing and
other necessary things like shopping.
In the morning we used mainly 17 and 20 meters. Around noon, 15 meter was sometimes open for a
few hours, mainly to Japan and some North-America. 12 meter was only open to Japan.
For Europe 17 and 20 meter were the best bands. By the way 20 meter was the best band for all
continents.
30, 40 and 80 meter were also good bands, but also difficult for western Europe.
On day 3 we moved the 40 meter vertical more to the beach. The noise on 40m was high. After we
moved it, the noise was reduced at least with 6 dB. We had no coax-cable left, so we had to combine
17m and 40m.
It seems that everything direction 350 – 10 degrees (western Europe) was extremely difficult. That is
the reason why there are only a few F, DL, ON, PA, G and GM are in the log. The propagation stopped
around Poland, it didn’t move further to the west.
On 60 meter we had a tremendous S9+ QRM, it was some QRM generated in our resort. We replaced
the polarization of the antenna from vertical to horizontal, but that didn’t help. The day after we
hang the dipole 50 meters further away from the buildings, the QRM was still the same. We could
make much more QSO’s in the log without this QRM. FT8 was doing a good job getting the weak
signals out of the QRM.
The last morning the QRM was at the minimum and we logged many Western Europeans on 60
meters.
Our DHDL receiving antenna was not performing well, we tried it the first day, but without success on
all the low-bands.
Propagation on 160m was terrible. We were forced to use an inverted vee instead of an inverted L.
The noise on this band was S9, very difficult to copy anything. On the DHDL antenna the signals were
not readable at all. I tried also listening on the 80m vertical, but the noise was also very high.
So, we were forced to use FT8 also on this band. We didn’t make many QSO’s on 160m. We spent
our effort on the other bands due the high noise on the magic band.
In total we make a little bit more than 17.098 QSO’s which off 7.240 unique calls. We expected a little
bit more, but the circumstances did not allow much more.
During our last weekend on Tonga we participate in the CQ WW CW Contest. Participating in a
contest from the Pacific is completely different than contesting from Europe. It was a nice
experience, we learned a lot of it. We made in total 1.700 QSO’s in the contest. Without the contest
we would have made more QSO’s in the same time. It is difficult to find a clear frequency and after
that to keep your frequency. A lot of times we were covered by the NA and EU mesh.

Last day
We had to pay a lot of overweight coming to Tonga. We didn’t want to pay it again on the way back.
The price of the overweight was more that the new value of the mast and coax-cable.
We decided to find another way to send the fiber mast and coax back home, the alternative was
leaving it on Tonga and buy new ones at home.
But why not sending it to Tarawa for my next DXpedition to Kanton T31EU?
After a few telephone calls we made the decision to send it to Tarawa, that was much cheaper than
sending it back home and take it with us to Kanton in February.
The last morning we packed the ski-bag (35 KG) and brought it to Fiji airways for transport via Fiji to
Tarawa. Chuck our contact person on Tarawa would take care of the final handling of the ski-bag.
We had another quick visit in town before we went back by bus to the resort. The last stuff was
packed and at the end of the afternoon we were ready to leave for the airport. After 2 ½ hour flight
we arrived at Auckland airport. We went to a hotel for a few hours sleep. At 09:00 o’clock in the
morning we went by taxi to the city center for a breakfast. After breakfast we walked around a little
bit and went back to the airport. The flight from Auckland to Doha was 17½ hours. It was a very
bumpy flight. Arriving at Doha airport we had another 8 hours transfer till our departure back home.
We went to a lounge to relax, we had a nice shower and breakfast. After a few hours the team
separated, Pat went back to London, Tom to Edinburg, Martin and I to Amsterdam. 6 hours later we
were back in the Netherlands after travelling for two days.

QSL
Tom, GM4FDM is our QSL manager, all QSL will be answered by Buro, OQRS and Direct.
A short time after our DXpedition the logs will be uploaded to LOTW.
