CQ WPX CONTEST 2016 REVIEW AND ANALYSIS

Posted in Contest on June 7, 2016 by YE1ZAT

YE1ZAT telah menyelesaikan 3 DX Contest pada tahun 2016 yang kesemuanya adalah CQ WPX Contest. Diawali dengan CQ WPX RTTY di awal tahun, kemudian CQ WPX SSB di bulan Maret 2016, dan CQ WPX CW di akhir Mei 2016. Ketiga contest tersebut diikuti oleh YE1ZAT dengan kategori Multi-One Low Power.

Dari ketiganya, YE1ZAT masih memegang rekor Oceania untuk skor tertinggi yang kebetulan semuanya dibuat pada tahun 2015.

Di tahun 2016 ini, dengan pindahnya lokasi contest station dari yang sebelumnya di Gunung Malang, ke Grin Area Tambun, akan menarik tentunya untuk diamati apakah pencapaian yang sama bisa diperoleh tim di station yang baru tersebut. Berangkat dari kondisi ini, tim sepakat untuk tetap menggunakan kategori yang sama dengan target untuk memperbaiki rekor sendiri sekaligus menciptakan rekor oceania yang baru.

CQ WPX RTTY 2016

Skor akhir untuk kontes ini telah dipublikasikan. Dan seperti yang telah diprediksi sebelumnya, akhirnya YE1ZAT pada tahun 2016 berhasil memperbaiki rekor sendiri dan menciptakan rekor baru untuk Oceania. Target Tim akhirnya bisa terpenuhi dan merupakan awal yang baik di tahun 2016.

Yang unik adalah perolehan skor yang diperoleh pada 2016 dengan kategori low power lebih tinggi dari pencapaian yang diperoleh pada 2007 dengan kategori berbeda di high power. Terlepas dari itu semua, tentunya menjadi suatu kebanggaan tersendiri bagi tim untuk bisa mempertahankan prestasi ini dan akhirnya bisa menciptakan rekor baru untuk Oceania.

Tinggal menunggu apakah pada mode SSB dan CW, YE1ZAT bisa mendapatkan hasil yang bagus sebagaimana halnya yang telah diperoleh untuk RTTY. Sebagai baseline, pada mode SSB dan CW, untuk kategori multi-one low power, YE1ZAT juga masih memegang Rekor Oceania yang kebetulan semuanya diperoleh pada 2015.

CQ WPX SSB 2016

Kans untuk memperbaiki rekor Oceania yang dibuat sebelumnya pada 2015 terbuka lebar bagi YE1ZAT.

Raw score yang diperoleh YE1ZAT pada 2016 melebihi pencapaian yang dilakukan oleh tim pada tahun sebelumnya. Meskipun baru raw score, namun berdasarkan pengalaman sebelumnya, hasil tidak terlalu berbeda jauh. Reduksi skor pasti ada, namun mudah-mudahan reduksi yang terjadi masih dalam range sesuai prediksi sebagaimana hasil pada kontes sebelumnya.

CQ WPX CW 2016

Merupakan seri penutup untuk kontes CQ WPX di tahun 2016, sekaligus ajang silaturrahmi tim menjelang Bulan Ramadhan yang akan tiba beberapa hari sesudah kontes, seluruh angota tim YE1ZAT berkumpul kembali di Station GA Tambun untuk mode CW.

2 hari menjelang kontes berlangsung, pada tanggal 26 Mei 2016, YC1MR – OM Kasmuri dan YF1DO – OM Danu menyempatkan waktu berkunjung ke lokasi station untuk memastikan semua hardware dalam kondisi siap pakai, sekaligus melakukan setup pada software. Untung saja mereka berdua melakukan pre use check ini, karena pada salah satu sistem antenna ditemukan masalah sehingga penunjukan SWR sangat tinggi. Dari troubleshoot yang dilakukan, akhirnya OM Kasmuri menemukan pin pada male connector di transmission line patah, dan akhirnya penggantian dilakukan pada connector tersebut sehingga penunjukan SWR kembali ke normal.

Pelaksanaan kontes sendiri pada kali ini benar-benar berjalan sesuai dengan rencana yang telah didiskusikan. 2 pesawat digunakan selama kontes. Pesawat pertama digunakan sebagai pesawat utama, dan pesawat kedua hanya digunakan untuk melakukan scan terhadap band dan multiplier. Operator pada pesawat kedua ini memegang peranan penting untuk memberitahukan kepada operator pesawat utama pada band mana seharusnya contest station bekerja sesuai dengan kondisi propagasi sekaligus melakukan scanning untuk mencari station multiplier baru.

Pada awalnya, untuk pesawat scan digunakan IC-7100, namun pada hari ke-2, tim mendapatkan kesempatan untuk mencoba pesawat baru IC-7300. Kebetulan salah seorang rekan ORARI Lokal Bekasi YC1LDZ – OM Dicky, yang baru membeli perangkat tersebut, berkenan untuk meminjamkan perangkatnya yang baru dibuka dari bungkus untuk dicoba pada kontes ini.  Seluruh anggota tim mengucapkan terima kasih untuk OM Dicky, atas peminjaman IC-7300 yang benar-benar masih dalam kondisi baru dibuka dari bungkus, dan dicoba pertama kali untuk kontes.

Di akhir kontes, tim berhasil memperoleh skor akhir yang sangat menggembirakan 3,947,467. Sunguh merupakan suatu pencapaian yang luar biasa meskipun masih berupa raw score. Pencapaian ini sekaligus juga menjawab pertanyaan salah seorang anggota tim YC1ME pada 2 minggu sebelum kontes berlangsung, yang menanyakan apakah mungkin tim bisa memperoleh skor di atas 3.5 juta pada low power dengan lokasi station yang sudah tidak lagi berada di Gunung Malang.

Dan apa yang sudah ditunjukkan oleh tim berupa perencanaan dan strategi yang baik, implementasi dari strategi, serta tentunya integritas seluruh anggota tim yang sangat tinggi untuk memberikan yang terbaik bagi ORARI Lokal Bekasi dalam kontes kali ini telah menjawab pertanyaan dari YC1ME tersebut.

Raw Score_cq wpx cw 2016

Gambar 9. Detail pencapaian di akhir kontest CQ WPX CW 2016

Melihat dari pencapaian yang sudah diperoleh selama kontes, sesuai dengan rencana dan strategi yang didiskusikan di awal, tim memang sangat fokus pada low band mengingat pada band ini, poin lebih tinggi dibandingkan dengan high band. Bahkan saat 10 meter band cukup terbuka di hari pertama (Sabtu Sore), tim tidak terlalu antusias untuk mengejar pencapaian di band tersebut, sehingga pada saat yang bersamaan, dari hasil scanning pada pesawat ke-2 di mana 40 meter band mulai terbuka meskipun tidak terlalu banyak station bekerja saat itu, tim langsung berdiskusi dan memutuskan segera meninggalkan 10 meter band untuk CQ pada 40 meter band.

Hal ini cukup membuahkan hasil, meski di sela-sela local pirate station dengan power besar yang bekerja dengan phone pada segmen CW, perlahan mulai banyak station di 40 meter band yang bekerja dengan YE1ZAT. Memang kendala terbesar adalah keberadaan station yang bekerja dengan phone pada segmen CW tersebut, bahkan terkadang signal mereka menutup signal dari station yang bekerja dengan YE1ZAT di saat krusial, pertukaran report, sehingga tone dengan pesan NR ? atau AGN seringkali dikirimkan oleh operator pada saat bekerja di band ini. Namun kondisi ini tidak melemahkan semangat operator, dengan tetap fokus pada target yang harus dicapai sekaligus poin tinggi pada low band, operator tetap berusaha untuk bisa fokus bekerja di low band. Hasil yang diperoleh cukup membuktikan usaha ini.

Untuk 80 meter band, tidak banyak station yang bekerja dengan YE1ZAT, tercatat hanya 3 station pada log. Hal ini disebabkan kondisi band yang kurang begitu baik selama kontes berlangsung, sehingga tim segera mengambil keputusan untuk tidak fokus pada band ini agar tidak kehilangan peluang untuk mendapatkan poin dari band yang lain.

Raw score telah dipublikasikan dan dengan pencapaian yang diperoleh oleh tim, peluang untuk memperbaiki Rekor Oceania atas nama sendiri sangat terbuka lebar dengan pencapaian ini.

Tidak hanya berpeluang untuk memperbaiki rekor sendiri, bahkan pada kontes kali ini, untuk kategori Multi-One Low, YE1ZAT menempati posisi ke-3 Dunia untuk perolehan skor sementara. Suatu prestasi yang membanggakan khususnya bagi anggota Amatir Radio di Lokal Bekasi. Semoga hasil akhir nanti tidak jauh berbeda dengan raw score yang sudah dipublikasikan.

YE1ZAT had just accomplished 3 DX Contests in 2016 and they were part of CQ WPX Contest Series. Starting with CQ WPX RTTY in the beginning of the year, followed by CQ WPX SSB in March 2016, and CQ WPX CW at the end of May 2016 thereafter. The three contests altogether were participated by YE1ZAT in the Multi-One Low Power Category.

Of all contests with different modes above in Multi-One Low Power category, YE1ZAT still hold Oceania All Time Records and made in 2015.

In 2016, followed by station relocation that formerly located in Gunung Malang, to Grin area (GA) Tambun, it certainly be interesting to see if this team could gain same achievement in the new station with sama category. Based on the condition, team  agreed to go through the contest with same category, targeting to improve own record and set new Oceania Record for Multi-One Low Category.

CQ WPX RTTY 2016

As predicted before, final score of this contest eventually brought YE1ZAT improving their own record as well as setting New Oceania All Time Record. Very good start in 2016.

Unique thing revealed achievement in 2016 with Low Power Category even higher than those being achieved in 2007 with High Power Category. Apart from all mentioned above, this certainly become a pride to the team member to maintain achievement and set New Oceania Record.

We will see if in other modes SSB and CW, YE1ZAT could gain same result as RTTY. For baseline, in SSB and CW, Multi-One Low Category, likewise, YE1ZAT still hold Oceania All Time Records set in 2015.

CQ WPX SSB 2016

Opportunity to improve Oceania Record made by YE1ZAT in 2015 was visible.

Raw score obtained by YE1ZAT in 2016 exceeded achievement made by team in the previous year. Despite of just a raw score being published, based on previous experience it should have reflected achievement as published for final with no big difference. Score reduction would certainly exist without no doubt, however, this reduction was expected to be within allowable range as predicted.

CQ WPX CW 2016

It was a closing contest of CQ WPX series in 2016, as well as team gathering moment prior to facing Holy Month Ramadhan in the next few days, all team member again got together in GA Station Tambun to take part in CW mode.

2 days prior to contest started, in May 26th 2016, YC1MR – OM Kasmuri and YF1DO – OM Danu spent their time to visit contest station and making necessary preparation for hardware and software to ensure that contest gear is ready. Fortunately, they came to verify things with pre use check, since they encountered problem on one of antenna system that exhibited high SWR. Further troubleshoot undertaken, OM Kasmuri eventually found broken pin of coax male connector, replacement was then carried out, hence SWR was just resumed back to normal.

The contest run as planned. 2 rigs were used in a contest. The first one was used as main rig while another one was used only for scanning on the bands as well as multipliers. 2nd rig operator played role in the game to inform main operator on which band should team worked based on propagation, likewise, scanned new multipliers worked during the period.

In the beginning of the contest, IC-7100 was used as 2nd rig, however, in Day-2, team had a chance to try newly launched rig IC-7300. It happened when one of Bekasi Chapter Member YC1LDZ – OM Dicky, was willing to lend his brand new rig and tested for contest purpose. Team was really grateful and would like to convey many thanks to OM Dicky for sort of opportunity in conducting equipment testing for contest.

At the end of contest, team could gain promising final score 3,947,467. It was a great achievement though still a raw score. This also answered a question raised by one of team member YC1ME 2 weeks prior to contest, whether team could get score above 3.5 millions with low power from station that no longer located in Gunung Malang.

What team had exhibited i.e. good planning and strategy, strategy implementation, and of course high integrity to deliver the best thing for ORARI, mainly Bekasi Chapter had answered sort of question eventually.

Raw Score_cq wpx cw 2016

What had been implemented and achieved during contest, was just exactly as planned and discussed in the beginning, where team paid focus on low band due to point wise. Even when 10 meters band was favorable in Day-1 (Saturday Evening), team did not expect to spend much time on this band. When scanning from 2nd rig revealed 40 m was open at the same time though not many stations working, snap decision was made by immediately switched the antenna to 40 meters and followed by CQ.

This attempt was successful. Despite the presence of local pirate station on 40 m with high power working with phone on CW segment, gradually YE1ZAT found many stations being worked. Well, that was a biggest handicap working on 40 with the presence of pirate station on phone, where sometimes their signal masked the station being worked in the very crucial moment, exchange report, resulted in too frequent tone sending with NR? or AGN sent by YE1ZAT Operator. However, this would not weaken spirit and team focus in having communication on low band. Resulted score had proven this.

On 80 meters, not many stations YE1ZAT worked with, only 3 stations being logged. This was due to unfavorable band condition during contest, therefore team took snap decision to leave this band right away in order not to loose points on other bands.

Raw score was just published and with kind of achievement, team might improve own record and set new Oceania All Time Records for Multi-One Low by YE1ZAT last year.

CQ WPX CW

Not only have a chance in improving own record, even for this contest, with Multi-One Low Category, for the time being YE1ZAT finished 3rd position on World Contest Standings. What a great achievement exhibited by ORARI – Bekasi Chapter in DX Contest, and hopefully final score would not be reduced too much.

Also, we expect this ORARI Club Station will still keep exist in the future with great achievement and triggering other chapters in Indonesia to take part in DX Contest.

Thanks to YD1DOQ – YL Oki, who cooked and served us with delicious Nasi Rawon during contest, and also YD1DGZ – OM Hendar who kept maintaining availability of logistic supply while sneaking as Contest Operator.

POTENTIAL OC RECORD-BREAKING ON CQ WPX RTTY 2016

Posted in Contest on February 27, 2016 by YE1ZAT

CQ WPX RTTY is the first contest agenda for YE1ZAT to take part in 2016. Team went through this event with promising result eventually.

Occupying new room though still in the same building where this station was built, had introduced new spirit to entire team member. At the end of January 2016, following renovation on previous operator’s room, all gears as well as transmission and electricity line hook up were undertaken and relocated to a new room at GA building. Afterward, when this relocation was accomplished, the first agenda was about to come in February 2016, CQ WPX RTTY Contest.

The target being set up was to break previous score achieved in the same contest last year (2015) with same category, Multi Operators Single Transmitter Low Power.

Apart from target settlement by team, one of team member, Danu YF1DO challenged us to reflect on past achievement in 2007 when former team could set Oceania Record 1,580,558 with high power as shown below :

Previous CQ WPX Record

We thought that nice to have it broken at the beginning, moreover this time we went with low power category powered up from an entry level rig Yaesu FT-450 barefoot. So that would be just a dream and we headed up for it but not to be piled on pressure to make it happened.

Three times power outage had been experienced by team, either planned and unplanned. The first one was due to massive lightning strike occurred around station area that forced us to put all electricity breaker off, while the other two were due to outage from electricity network. Those disruption occurred in Day-2 of contest with total loss time of 3 hours and 20 minutes. It was not expected situation indeed while we aimed to break our own record.

Situation was just about to change when we still had hopes upon all disruptions went away. All member’s passion and commitment even though with disruptions that followed, finally brought to the target achievement when at the end of the contest we scored higher than this team gained in 2007 with different category.

Raw score of this contest result was just published and we will probably break our own record and set new Oceania Record as follow :

Raw Score Oceania Multi-Single Low 2016 CQ WPX RTTY

It was still just a raw score, and we will look forward to upcoming final score published, anyway. However, based on previous result and experience, the standings will not change significantly despite of potential change in actual score upon final review.

Below was situation when team enjoyed “nasi uduk” as breakfast after contest ended

Other than complimentary to all operators involved, special thanks need to be conveyed to Kasmuri YC1MR, Oleng YD1OLG, and Rizal YD1ORZ for hooking up 7 elements tribanders and 3 el full size that made our FT-450 barefoot power efficiently transmitted very well. This entry level rig with all its limitation really talked a lot than ever been expected:)

Now we believe that efficient antenna is the most powerful amplifier and play big role in a successful communication.

Heads up for upcoming CQ WPX SSB in March 2016.

CQ WW CW 2015

Posted in Contest on December 9, 2015 by YE1ZAT

It had been planned before that for the very first time, ORARI Lokal Bekasi (Local District of Bekasi) would participate the contest with 2 teams, YE1ZAT for Low Power and YE1K for High Power. Everything was completely prepared few days before as well as how coordination should be made to prevent interference each other during contest.

Pre-Contest Technical Meeting

On Friday, November 27 2015 @ 16:00 Local Time (09:00 UTC), all team members conducted a technical meeting. Many aspects were discussed herein :

  1. Whether 2 teams would participate in 2 different categories, this was outlined in several options
  2. Strategy and job assignment

First agenda in determining category should be resolved first since this would affect the strategy in the contest. Each of team member involving Old Generation and New Generation raised their opinion to which option should be taken in facing this. This was sort of team’s tradition that has been lasting for long. The good thing was contingency had been organized for any of options.

Technical Meeting 2

Pic 1. Left to Right : YD1DGZ, YC1MR, YC1DPM, YB1KAR, YD1DOQ, YC1ME, YF1DO (explained the strategy)

Voting was taken as way to take decision based on various considerations delivered by each team member. Having considered many aspects might coexist, eventually voting revealed YE1K for contest station with 1 category at this time (Multi-Two High Power).

Target being set by team was minimum 4000 QSOs or 5,500,000 minimum score.

After its vacuum for about 2 years in DX Contest, this was the first comeback of YE1K, merging the skill of Old Generation and New Generation.

Technical Meeting 3

(Pic. 2 Left to Right : YC1NWE, YB1CF, YC1KAF, YD1DGZ, YC1MR, YC1DPM, and YB1KAR)

This technical meeting was not only attended by present contest team member. To express support for contest team, we had a visit from YC1NWE (OM Toto) as one of Board Member in ORARI Lokal Bekasi, YB1NWP (OM Nyoman) as one of YE1K member, and YD1ARM (OM Aris) that became part of YE1K also.

Both YB1NWP and YD1ARM are well known as the most eligible technician here in the team. They had contributed a lot for the team and still actively engage mainly to those requiring technical decision based on their nature and area of expertise.

Within minutes just after technical meeting was closed, YB1PR (OM Faisal) and YB0QA (OM Erdius) came over and shared their experience as well as encouraging all team members prior to contest.

One of the moment that had been waited by all team members was about to come…DINNER. Unlike previous 2 contests preparation at this station, this time we had special menu cooked and served by YD1DOQ, YL Oki who brought all dinner food and stuff from her place. Many thanks, Oki…all that you served were so tasteful, mainly Sop Kambing and Sate Kambing.

Day-1

Pic. 7 : Just 90 minutes to go

Many aspects when taking Multi-Two Category should be taken into account. Good thing that YD1JZ and YF1DO managed these (hardware and networking) exceptionally well, days prior to D-Day. We were up to this point, with having all hardware as well as networking passed function test and loop check. What an outstanding job that resulted in outstanding setup. No surprise in Day-1 that would lead to contest disruption in term of hardware failure.

Day-2

Small incident occurred in starting Day-2 of Contest. One of the rig used for contest gear and probably the most demanded gear that this team member like to play with, Elecraft K3 experienced a problem. None of us but YD1JZ, OM Joz had in depth skills in how to explore all available menus and technical aspect of the rig. It happened when YC1ME started to operate this after his rest, he felt this rig behaved quite unusual compared to previous use. Soon afterward, troubleshoot was conducted by YF1DO, and he found that plastic cap at rig’s grounding lug melted and suddenly it switched off automatically.

…EUREKA…having routed the ground line to find the real culprit revealed loosened end point of this line and in contact with switching power supply was the root cause. We then decided to switch off all appliances and rearrange grounding system. Once all grounding system was completed and properly wired to prevent inadvertent contact that undesirable, things were powered up. Gotcha, this beautiful gun was back and normal, except a small plastic grounding lug cap that being melted must be replaced someday.

There was always new lesson learned that team always gained in every contest, this contest was no exception.

YB1KAR and YD1DGZ

YC1ME and YC1KAF

(Pic. 10 YC1KAF and YC1ME)

In general, propagation always plays a significant role in any on-the-air activity, and contest was no different situation that being affected. Team thought that 10 meters band was not favorable this time. This applied to all contestants where achievement on 10 meters band was not satisfying though.

This contest ended with final claimed score 5,356,233 of all 3796 QSOs. This was away of target set before.

Claimed Score CQWW 2015

(Pic. 11  Contest Claimed Result)

Post-Contest Technical Evaluation

Led by YB1CF, OM Yoyon, team conducted evaluation immediately an hour just after contest ended. First evaluation was raised by YD1JZ as he actively monitored from time to time the team progress over years as well as each operator progress.

Several things became his primary concerns :

  1. There are still some gaps need to be filled in by this team in the future as he thought that this team should achieve better than what was just gained. Not to mention technical aspects that might differ for each operator, non technical aspect concerning rest management was pointed out also.
  2. Progress of each operator, he delivered his opinion that some of us made good progress in performance but some degraded. It is certainly a human nature, but some affecting the performance should be manageable based on his opinion. Special complimentary was conveyed to YB1KAR as he made an outstanding progress. At the same time, YB1KAR shared his experience why he could manage this better compared to previous contest. One thing to be noted herein that he made absolutely well preparation through practice and exercise a month prior to contest. He led this by real example mainly to all team members. Despite along with YD1JZ, YC1KAF, and YB1CF, he is one of the experience team member, he felt that he still need more practice, practice, and practice, certainly need to be balanced with maintaining health prior to contest.
  3. Knowledge and skill transfer between Old Generation and New Generation Team.

Just like pre-contest technical meeting, each member had opportunity to share their mind related to what we had just gone through and what to improve in the future. For new generation team, as successor of YE1K someday,  this contest was a tool in bridging skill and knowledge transfer from senior. It takes long process for them to be in the same level and cannot be instantly achieved, but nothing is impossible. At least, from this contest, new generation had learned not limited to technical aspect but also non technical aspect that greatly affects end result.

Looking at big picture, very good thing that more Indonesian Amateur Radio Stations took part in this CW contest had evidently showed new enthusiast in enjoying this hobby. The doomsday prophecy that Morse Code is a dying art again…again ….and again proved to be false. This hobby will keep alive and occupying room in amateur radio.

SKY IS THE LIMIT !!!

Posted in Uncategorized on December 8, 2015 by YE1ZAT

Yes, it sounds too exaggerated. But no better words to describe effort that YE1ZAT had demonstrated recently. In the first week of November 2015, with purpose of getting better performance on both TX and RX, improvement was made on the antenna. To get better gain on existing GA station antenna, 7 elements were installed instead of 4 elements ones that previously served for few months only. Furthermore, the tower that supporting this antenna was also raised from 20 meters to 43 meters

 

Raising main tower

(Pic.1 : Process in raising tower for 7 El. Tri-banders, viewed from distance)

Preparing 7 El Tribanders

(Pic. 2: Final Assembly of 7 El. Tribanders, supervised by YC1MR, OM Muri)

Another improvement made on the yard was the presence of antenna rotator compared to manual effort in rotating the antenna using tag line on boom tip before. This would in certain introduce ease of operation for team as well as performance enhancement.

Assembled

(Pic.3 : Main Antenna was completely assembled and raised, viewed from bottom of tower)

It looks like team had seriously prepared the upcoming CQ WW – CW Contest by the end of November 2015.

Herewith the most updated technical information of latest GA installed antenna:

Having this done, will there be other modification might follow? None can tell, since more than adequate room for improvement is always there.

Again … sky is the limit.

CQ WW SSB 2015

Posted in Contest on October 27, 2015 by YE1ZAT

YE1ZAT again took part in CQWW SSB Contest 2015 from station in Grin Area, Tambun. Some troubles with contest gears occurred within contest period 24-25 October 2015.

Day-1 (24 October 2015)

Achievement up to first 8 hours evidently described the actual situation when only 100 QSOs could be managed following problem with tribanders antenna. In spite of propagation was favorable on 15m band during first 8 hours where QSOs were focused on DX station in north, however, above condition would not much help unless main problem was sorted out.

Upon all team members felt that something went wrong with current installed tribanders antenna, meanwhile that was not a good time to transmit on 40m, YE1ZAT contest coordinator Danu, YF1DO decided that game plan should be changed immediately by rectifying main root cause as soon as possible.

Soon afterward, Muri, YC1MR came with his crew along with some materials required to build new antenna for 10-15-20 meters band. Contest should move on, no matter problem still existed and not being rectified at the time. In order to maintain contest continuation, while some repairs were conducted on main antenna, team worked together in assembling temporary antenna.

CQWW SSB 2015_1

(Pic. 1: Emergency antenna preparation while main antenna required some repairs during contest)

This new temporary antenna was installed no higher than 6 meters above ground and certainly not much to be expected from kind of installation for DX purpose.

CQWW SSB 2015_2

(Pic. 2: Repair process on main antenna)

Problem seemed would not end, at around 12.00 UTC in the first day of contest (19.00 local time), power outage occurred in the station and surroundings resulted from electricity network trouble followed by computer hardware problem once power resumed to normal. This unwanted situation at least impacted to QSOs achievement.

Having 24 hours of contest in Day-1, team could only manage up to 267 QSOs, for sure this was not a good achievement.

Day-2 (25 October 2015)

Based upon what had been achieved in Day-1 of contest, it looked like impossible to meet number of QSO target that was setup during technical meeting few days prior to contest. During technical meeting, senior contest team member that also Station Owner Joz, YD1JZ and Contest Coordinator Danu, YF1DO during their briefing had set minimum 1000s QSO should be achieved by New Generation of YE1ZAT.

Team started Day-2 with very big gap to fulfill, it was not an easy job though.

Again and again, in Day-2, self same problem concerning power outage started to occur at 04.00 UTC (11.00 local time) with more severer impact than it was in previous day. The problem impacted to computer monitor to PC communication failure and some interface configuration change resulted in computer aided system deficiencies. This in turn led to manual logging system must be undertaken for few QSOs

With all gaps above, approximately 4 hours downtime required to cure the problem. Once all problems were completely rectified as well as logging system at 10.00 UTC (17.00 local time), team could only manage 483 QSO and had only 14 hours left to accomplish the contest with target to be met.

Given remaining time available, extraordinary efforts in meeting the target seemed to be possible when finally team could manage 803 QSOs at 14.00 UTC (21.00 local time), and just requiring 197 more QSOs.

Final Result

Antenna troubles, computer monitor problem, interface communication failure, and power outage were all finally manageable but point of concern herein was team spirit to achieve target being set. It was definitely nothing without willingness and commitment until finally at the end of entire contest duration, team could accomplish 1012 QSOs with claimed score 869,760.

No matter the result would be for this contest, considering all difficulties had been experienced by team, one thing that needed to be pointed out was related with spirit to fill some gaps as well as continuing the game under difficult situation. This was primary concern, and team had demonstrated it exceptionally well.

None who visited team’s station at the time would think that this target could be achieved after team experienced all consecutive troubles mentioned above during contest. Spirit and commitment would eventually take all, supported by good team work, hence things became possible.

 

NEW STATION

Posted in Uncategorized on October 17, 2015 by YE1ZAT

Background

It has been about a year since past 2014 CQ WW SSB Contest, when all gears required for contesting were setup in ORARI Lokal Bekasi (Indonesia Amateur Radio Organization – District of Bekasi) Office. Since then, none of YE1ZAT Contest activities were operated from this office. Significant local noise encountered was considered to be main contributing factor, why this should become primary concern by team member.

Further, after having series of discussion involving YE1ZAT’s former team member, one of senior team member Joz, YD1JZ allowed his personal property to be utilized for next YE1ZAT activities with primary concern for DX-ing and of course contest. Proposed new station described herein is located in a location with more than adequate space for practice as well as getting rid off man made noise. This would certainly be good news considering continuation of YE1ZAT activities as well as providing facilities for new hams in shaping their learning curve.

Mobilization and Construction

Once all resources were completely managed and organized, led by Danu, YF1DO as present YE1ZAT Team Leader, required materials were mobilized from workshop owned by Muri, YC1MR to this new station location that well known as GA (basically taken from previous business unit name Grin Area, that was based at this facility) .

After spending several hours in constructing and erecting new antenna, this new station was completely setup eventually on Friday, September 18th, 2015 comprises 2 antennas ( dipole on 40m band and 4 elements tribanders 10-15-20 m bands).

Nothing so fancy on this newly hooked up antennas though, moreover, these were composed from already available materials in Muri, YC1MR’s workshop. Meanwhile, to bear at certain direction, both antennas are still relying on manual rotation by means of a tag line attached onto boom tip.

However, man behind the gun would be the key and plays role under any circumstances, and hopefully with this newly built contest station, practice and skill enhancement mainly to those related with amateur radio activities especially for YE1ZAT Team Member may be started and sustained.

Station Quick Performance Test

Resulted test performance conducted afterward, had proven that noise was greatly reduced compared against the one being setup in the former station. This performance test result was certainly a leading indicator for expected better outcome in upcoming DX Contest.

Furthermore, it must be noted, that contest is not the only activity accommodated by YE1ZAT. Club station’s activity is not limited only to contest, but also all aspects outlining skill enhancement of Bekasi Amateur Radio, and this station would certainly further facilitate the needs.      

First DX Contest at New Station 

Finally, the real test in contesting was about to come. A week after things being accomplished including minor adjustment, team had a chance to participate 2015 CQWW RTTY Contest under Multi Operator – Low Power Category ( September, 26 – 27, 2015 ).

While contesting activity kept moving on, other team member also took this opportunity in having digital operation knowledge share from present YE1ZAT “skipper” OM Danu, YF1DO. He took this opportunity to share his experience in digital operation to YE1ZAT Team Member, not limited to operating skill, but also how to properly setup software and hardware in digital. Even during sharing session, a ham fellow from Lokal Karawang (other district) Hadi, YD1DTE had this rare opportunity and taking part in this session.

Above picture shows how sharing session took place during contest. (from left to right : YD1DGZ, YF1DO-pointing his finger on screen, YC1DPM, and ham fellow from Karawang YD1DTE). This session demonstrated one of Amateur’s Code is “FRIENDLY” : He operates slowly and patiently when requested; offers friendly advice and counsel to the beginner; kind assistance, cooperation and consideration for the interests of others. These are the marks of amateur spirit.

At the end of contest, YE1ZAT achieved promising result in this category by having total claimed score 1,026,564.

Good station and location, as well as outstanding result obtained during first contest participation in newly reinstated facility will certainly be nothing unless team member’s spirit and enthusiasm are sustained. The new challenge has just begun, indeed.
