TERESINA DX GROUP - DX-pedition - JULY 2015

REPORT DX-pedition - SANTA ISABEL ISLAND IOTA SA 025 - DIB PI-01 and FAROL DA PEDRA DO SAL (ARLHS BRA 070), DFB PI-03, WLOTA L-2825 (2nd 49 '19 "S - 41º 26' 45" W)


             The Teresina DX Group conducted a DXpedition to Santa Isabel Island (IOTA SA 025 DIB PI-01) also activating the Farol da Pedra do Sal (ARLHS BRA-070, 2 49 '19 "S - 41º 26' 45" W) , also valid for WLOTA diplomas program (World lighthouses on The Air) with the code WLOTA L-2825 and headlights diplomas DFB Brazilian PI-03, on the coast of the State of Piauí coast, northeastern Brazil, between 23-26 July 2015. Amateur PS8BR-Joselito, PS8HF-Milton and PS8NF-Nelson were active with the special callsign ZW8K.

 The DXpedition occurred in parallel with the IOTA Contest 2015 on 25 and 26 July 2015, which started from 09: 00hs (12:00 UTC), whose goal of the contest is to promote contacts between IOTA stations with rest of the world and to encourage expeditions to IOTA islands. CW, SSB and competing in the Contest IOTA in the form MIXED:: CW and SSB on the IOTA Multi-Operators Category Modes were used.

TRAVEL: Start and Finish

The DXpedition was planned just two months earlier by Radio Amateurs of Teresina DX Group, PS8BR- Joselito, PS8HF- Milton and PS8NF- Nelson, they actively participated in operations in Santa Isabel Island, being assisted by other members of the group that had the Stand QAP Old Monk group Parnaíba-Pi.
The whole team came from Teresina-Pi city at 05: 00hs in the morning towards Santa Isabel Island. Because it is the last weekend of July holiday, the road was quite busy, requiring greater attention along the way. The trip took place smoothly, with a stop for breakfast near the town of Piracuruca-Pi. There was no unforeseen reaching the destination before the appointed time, around 09:30 hours, which began assembling the antennas and radios preparation for operations.


The venue for the antenna field, was in the sea, on the beach sand even where we could enjoy the ocean waves and a beautiful shade produced by a tent made of thatched palm trees. A compass for use in guiding the steering antennas in order to use directional antennas. All were carefully lifted and positioned so that there is no interference in each other. We made preliminary tests with equipment taken and obtained very low and satisfactory SWR, leaving us in a position to initiate the transmissions on the island.


This DXpedition, we aim to conduct a QRP operation, with simple equipment, low-cost antennas and made by ourselves. There has not been used linear amplifier and any other feature that could increase the equipment of output power. The following RADIOS were used: 02 (Two) YAESU FT-950 and one (01) Kenwood 241 (VHF)
The antennas are mounted: 2elements for 10m , 2 elements for 15m and 3 elements for 6m , dipole for bands of 12,17,20,30,40,80m and a vertical antenna 10 / 40m , all properly located and not to interfere with each other. They were simple antennas but yielded in great QSOs and excellent results, and that could be carried in our backpacks. During assembly we took a break for lunch returning activities after tasting a wonderful fish stew.


The first contact of the DXpediton was made with the  KP4TF station at 20:23 in the frequency 21013.00 MHz CW, which reported in a RST 599 and was carried out by PS8BR Joselito, who at the time showed great satisfaction for having had the opportunity and privileged to hold this first contact of the DXpedition. At the beginning of the operation, we had some difficulty understanding the spread because we were without internet and without ideal communication with the other comrades of the Teresina DX Group. We try to get internet signal through the existing cellular, but none were able to connect, including access social networks or clusters was impossible at that time. We understand that our mission would be further than we had planned because we were beginning the first improvisations of the day, that night, time that actually began operating. We position the antennas to the EU and USA and Brazil and started to call, to our surprise we were soon copied by KP4TF.
When night fell really noticed some other problems that we would have to face, it was a loud noise at the front desk. We left behind the cause and did not take long to discover that just about a thousand meters, revolved powerful and gigantic propellers of modern generators aeólic energy park that is being built on the island. We also noticed that the wind was very strong, especially during the night, so that the antennas had to leave the positions defined. Despite already well held directional antennas, we had to tie up with ropes and car tire rubber strips to actually fix them in their places. Now the dipole antennas, there was the need to establish more coaxial cable, which shook a lot. On the second day of use of the antennas, the 40m left your coaxial cable, powered the team to two o'clock in the morning fix there, in this case we change the coaxial cable that broke and everything returned to normal and then part of staff was taking a nap.
We also noticed that the spread did not help us much in the high bands. In 6m and 10m we perform only ten contacts throughout the DXpedition. Very noise on all bands. In 15m,20m, 30m and 40m had good yields every day. It was hard to pierce the wall formed between the United States and Europe, but from time to time someone found us there and we could catch up. The antenna Vertical worked well on 40 and 15m during the night, but on a low income during the day. We came to a conclusion that for our location, DXpedition in July, is not very favorable, due to lack of propagation. Sometimes, when spread open, I could only good results in telegraphy, compared to telephony. Theoretically we should do good contacts in all modes, but in practice did not occur to us on phone. In digital modes, we had scheduled operation, but could not due to defective presented in the cables, leaving this dead mode.


We were honored to receive the support of the QAP Old Monk Group Amateur Radio City Parnaíba-Pi, which is composed of 25 hams. They Made the photos to register their presence with the team ZW8K.
The DELTA TV, Television in Parnaíba-Pi, made a report on the expedition, trying to show that the objectives Amateur group were gathered in Santa Isabel Island, in order to participate in an international competition of Amateur Radio. It was given the opportunity to station represented by PS8NF Nelson, to explain the difference between the Amateur and Transceiver, which is commonly mistaken for police approaches and the media itself. He was in focus also the QSL card, so that the Amateur Radio confirms your contacts is valid for some existing certifications. To complete their work made a video and interview to Local Newspaper showing the importance of radio amateurs to society in the event of disasters and emergencies, in addition to being a hobby.
Were on site with their wives, the PS8TV Dalton and Luiz Carlos, both from the Teresina DX Group.

Hams reach Parnaíba to international competition
The amateur radio, or Amateur Service is practiced in almost every country in the world by skilled and licensed by authorities for intercommunication and technical studies without profit motive. The hams come in 'scene' every time a disaster happens, a big accident and the most modern means of communication fail.

Passionate about it, Nelson de Almeida explains the term amateur specification, which is often confused, because some people associate with the device, but in fact it is the person who handles the radio and makes operations.

Amateurs of the capital, Teresina DX Group team came to Parnaíba and chose the beach Pedra do Sal to carry out activities relating to competition that starts this Saturday (25/07). The Teresina DX Group started the DXpedition to Santa Isabel Island (IOTA SA 025 DIB PI-01) on the coast of the State of Piauí coast, northeastern Brazil.

According to Almeida, another important point about amateur radio is the existence of the QSL card, which is considered the business card of a ham. Fits register each first contact and to prove participation in various forms of competition; to receive international and other certificates. Send the QSL card when the first contact with a radio colleague, is operating ethics.

The DXpedition will take place in parallel with the IOTA Contest 2015 on 25 and 26 July 2015 at 9am (12h UTC), whose goal of the contest is to promote contacts between IOTA stations with the rest of the world and to encourage expeditions to IOTA islands.

In Pedra do Sal, there was a meeting of members of the Teresina DX Group and the amateur radio group QAP Old Monk Parnaíba, which has about 20 participants.

Joselito Rodrigues also ham, also pointed out how it is done up with other countries, since it is possible to make contact with the whole world and the language is universal among them is universal, which use the English language.

At the time, the ham showed still very used equipment that is Handler Telegraph, which is a slower communication but effective. This was used in the period of World War II.
