YJ0HA Vanuatu
1-15 November 2010


 

Paradise Cove, Efate IslandOperators: HA5UK, George,  and HA5AO, Pista.
The station(s) will be set up in the Nirvana Resort, Paradise Cove, Efate Island, Vanuatu.
The callsign: YJ0HA.

Operation is planned on the 160-10 m bands, using CW, SSB, RTTY, PSK, SSTV modes. More details, like station setup, antennas, etc. will be announced in due time. Logsearch will be available here. QSL via HA5AO and LotW. Click here for detailed QSLnformation.

 

 

Emae Island, OC-111During our stay in Vanuatu we are planning operation from Emae Island, OC-111, Shepherd Islands group, as well. Only a one-day operation can be expected. We will do our best to organize this trip, but it highly depends on the local circumstances and possibilities, as well as, the weather conditions. We will keep you informed.

 

 

 

George, HA5UK has made the HFTA calculation for our QTH at the Nirvana Resort, Port Villa, Vanuatu. There is no vertical option available in the HFTA software, so the calculation based on dipole antenna at 10 meters up, as compromise.

We will use verticals in salt water, so we expect even better results to these main directions.

TNX for the valuable technical advices and as well as for the many trick and tips to HA7RY, Tomi and AA7JV, George, the crew of the memorable VK9GMW and the unforgettable TX3A expeditions.

 

Setting up the antennas at low tideWe arrived to Vanuatu on Monday late afternoon, early evening. We started to set up the station in Thuesday morning. It took couple of hours to set up the station and test everything, but when we finished it, there was mains blackout for a couple hours. We are running one station with 400 watts

The antennas are set up on 12 meter high spider pole in the salt water. The good news is that we have exeded 5000 QSO in the first 4 days. The pile up is huge on all the bands, as you also can hear.

The bad one is that, unfortunately, we could not be on the air as much as we liked, due to the efforts we made to be QRV on the 160 meter band. We made all the efforst to be on the top band, as well, but we have to decide to make more antenna tests or to operate on the other 8 bands. After 4 days of unsuccesful efforts, now we decided to operate as much as possible on the rest of the 8 bands and we will not continue the very time consuming antenna test for 160 meters. Sorry, but we hope and do belive that still there is life beyond the 160 meters band. There is very high demand for YJ on the other bands, as well.

The internet access is limited, however we can upload the log to the LotW and to the log search, but we can not upload photos. We will do it after arrival back home for you better information on our daily life on the island. 

Tha antenna maintanance is a permanent daily program due to the strong destructive effect of the see. That is the number one project each morning during the low tide.

During the night operation we need to ask QRX frequently due to the insect invasion. The repellent is our best friend during the night

Now we kindly want to rise the EU station attention again and again to their very bad operating practice. We want to ask more patient and attention in the pile up. It should result more chance to log you. We can achive 3, 4 times higher rates working with stations from other continets. It means 3, 4 times more stations in the log. Please consider when you have the higher possibility to have you logged? If you call us continously without any respect to the other station we call, you making difficoult for us to copy the right callsign and log the station we called only with several request to repete and clarify the callsign because of the QRM. It is very time consuming and means less chance for you to have logged. The solution is very simple and it is in your hand. Please call us with more patient.

The other aspect of this attitude: the DX station operator can hear the callsign of the QRMer station. Have these QRMer operator ever had thinking about what the DX operator shoul think about this person? It is not too difficult to imagine. We still belive in the good operating practice. Do hope it is not only a dream for us when we working with EU stations.

DSC05699aYesterday we had to fix the antenna coupler. It was not possible to tune the antenna on the 80 m band. We checked the coupler and we could see that the screw on the 16/81 m antenna port got loose and the relay demaged. We checked the coupler and we could see that the screw on the 160/80 m antenna port got loose and the relay was damaged and had to be replaced.

Fortunately we had replacement one. We had to remove the coupler from the pole, replace the relay, than back to the pole. It took more than three hours to getting back to the bands.

There were very strong QRN on all the bands.The propagation to Europe was not so good yesterday evening than before. The signals were very week on the 30 meters band and the QRN was getting stronger and stronger as the thunderstorm was getting closer and closer. Finally I had to go QRT at 11:40 UTC due to the heavy T-storm and tropical rain. It was not possible to be back to the bands for more than 7 hours. Early in the morning George was CQ-ing for more than one hour, but he could not get over to Europe, despite he could hear strong stations from there. The QRN still strong all the bands. The signals from State side on the 17 and 15 meters were also weaker. The sunspot number dropped back from 45 to 34. Today the weather is still rainy, the temperature dropped back to 27 C degree. We had to take T shirt, because it is cold. Hi-hi. The QSO number is exceeded the 7,000. We upload the log to the LotW and to the logsearch daily.

BeachWhen we fixed the antenna coupler we could tune the antenna for 80 meters, as well, without any trouble. The faulty rellay caused significant delay working on 80 meters. Yesterday morning it was working well. George could log several stations from EU. Most of them were week, but there were several big guns. The strongest station was HA7UG, his signal was like a cannon fire.

We are exceeded 8 kQSO. Very hard to work on 20 meters with Europe..Huge massive pile-up, for hours every evening.

The stations are strong here when the short path is open for you. The long path is obstructed for us by a small hill. The signals are week on LP.

The operation is slow with EU on all bands, due to the continuous callers and inpatient operators. This evening, 07-08 UTC, we will try 12 and 10 meters band again. The sonspot number is 34, so hopefully we can get over.

OC-111 operation: Unfortunately we have to cancel this trip, due to the circumstances and consideration, as follows,

We could find transportation to the island early in the morning. However we should have to spend the night there, as the motorboat can be back for us on the next afternoon only. We should have to spend the night there, but we could not find any solution to be in safe there. We could not take the risk to have an overnight alone on those remote island. Our safe is the first. Sorry about it, but we have had to make this decision. We can only hope your understanding.

YJ0HA QRT

YJ0HA final resultPlease be informed, that we went QRT after 12 days of operation on 14 November 2010 at 01:12 UTC (12:12 local time). We made 14 181 QSOs, excluding dupes, from 119 DXCC entities. You can see more detailed statistical figures on the log search page. The complete log are on-line and it has also been uploaded to the LotW.

All the QSO clarification and log correction request, we received by e-mail, will be answered after arrival back home. Thank you for the contacts and please accept our sincere apologies if we were not able to pick your callsing up in the pile-up.

Special thanks to our wifes for their kind help and support making our opearation more comfortable. Thank you for their patient and for their kind understanding, if we paid more attention to the operation than to them.

Rádióval a Föld túlsó oldalán - két hét az álomszigeten
YJ0HA – Vanuatu, 2010 november 1-14,
(HA5AO, HA5UK)

localvarior

A közös rádiós expedíció gondolatát 5AO vetette fel, a helyszínt illetően régi vágyam, a Dél-Csendes-óceán lett megcélozva. A konkrét sziget kiválasztása nem volt egyszerű, mivel több szempontnak kellett megfelelnie: Úgy döntöttünk, hogy családi vakációval ötvözzük a rádiózást, tehát megfelelő komfortra volt szükség,- Emellett kerülni akartuk a zsúfolt (ha nem is európai mércével zsúfolt) turista paradicsomokat mint Fiji vagy American Samoa.
