We will QRV from Mount Malang (1.050m ASL), 6°43.75′ S -107°39.58′ E Grid Locator OI33TG. Category Multi Op-Single Transmitter, High Power.

Last year, in the same contest and category, YE1C was awarded as #1 in Oceania and #1 in Indonesia and got certificate with score: 3,179,096.

Operators involved are: Gus YB1ALL, Yoyon YB1CCF, Nyoman YB1NWP, Terry YC1KAF, Danu YD1GCL, Joz YD1JZ and Jo YC0LOW with supporting team members: Heri YB1KAR, Muri YC1MRI, Yayan YC1BTV, Herry YC1HQQ, Oleng YD1OLG and Rizal YD1ORZ

We invite ORARI members to visit Mt Malang Ciater, West Java and for all other fellow contest-er, see you in the contest!

73 de YE1C team

In order to clarify, on behalf of YE1C team, I put some comments and/or suggestions, comparison etc. with YE1C previous operation in the same contest, 2010, written in parentheses (*).

Analysis and DX reports during pre-contest had already been written and published in a serials in OrariNews mailing list.

1. QSOs Data

a. Total QSOs = 289 (323).

b. Total Scores = 172.935 (166.314).

The increase from last year’s result is due to more multipliers achieved by YE1C in 2011. We broke its own score, and again, made highest record in Indonesia!

c. Countries = 54 (48).

The increase in the number of Countries. If there was no duplication in the acquisition of Country in 2010, then YE1C would be the only contest club station in Indonesia that entitles to claim the 100 DXCC Award in 160m CW to the ARRL.

d. Netted 18 stations from the United States (21) i.e from UT, NV, WA, CA, MT, AZ. (in 2010: AZ, CA, HI, TX, NV, WA, AK).

Several calls from the U.S. are from contest stations. They are rather passive in QSL-ing. I suggest to the YE1C manager to send first the card in order to be able to complete the collection of 160m, CW cards. For example, 160m stations from UT, TX, AK, NV are definetely rare audible in Indonesia.

Decreasing numbers of QSO with U.S. stations were due to poorer propagation than it was in 2010. In the contest days this year, sun rise enhancement – a natural phenomenon – did not exist here.

2. Propagation during the contest.

Propagation to JA-land was drastically deteriorated, this year. In contrast to 2010 where YE1C logged 122 JA stations, we made only 24 in 2011. Had in 2011 YE1C captured just 50% of the total amount of JA stations in 2010, the final score would have been more difficult to break by any other stations in Indonesia.

Data of daily number of QSO, below, clearly describes how propagation conditions were during contest days in 2011:

a. Day-One: 9 (32).

b. Day-Two: 201 (180)

c. Day-Three: 79 (117)

During the poor conditions, YE1C still obtained better final scores than 2010. This is because the team worked hard to give special attentions in installing nine receiving antennas (i.e: 1 full-sized low dipole, 3 Beverage, 1 4-square, 1 coaxial loop) in a strategic area of tea plantations, ideal and very quiet of noise in Malang Mountain (1050 ASL), Ciater, West Java.

Also, the operation is supported by several other factors, such as:

1. Features on the Icom IC7800 transceiver (built-in digital filters for rx, 4 rx inputs, etc.).

2. Linear Amplifier Emtron-3DX (legal limit) that worked flawlessly.

3. Homemade TX dipole antenna with feedpoint installation at ideal height at 45m.

4. Human Resources – mainly members from Orari, Lokal Bekasi, West Java, are all experienced at setting-up (RF equipment, electricity, accesories, computers) for contest (formerly team of YE1ZAT).

5. Adequate time of preparations for installment, the orientation, re-orientation and performance evaluation of quite many rx antennas.

6. An experienced CW operators (very comfortable with severe intermod CW tone, hi-speed)

7. The understanding of the mechanism of propagation 160m, softwares, analyzer and modern tools based Information Technology.

8. Supports from ORARI members who visited us (from Subang, Bandung, Bekasi etc.). Some are even willing to help us – while in sleeping – in repairing minor damages to the RX antennas at no cost (TNX to Buce YC1BAH, Nyoman YB1NWP and Aris, candidate member for the Bekasi)

Figure 1. Some of the RX antenna distributor box above the IC-7800.

3. Evaluation of RX Antennas.

a. Reversible Beverage KD9SV,

Figure 2. Feed transformers for reversible Beverage KD9SV. The background is a newly planted lettuce

First time tested in Indonesia. The installation is very practical because the feedpoint transformers (see Figure 2) for both directions (N-S) can be localized at the same point.

Twisted pair wire for antennas using WD-1A (used by U.S. troops in Europe during World War II) being extended in the direction 330 degrees to 150 degrees (to Europe and VK/ZL directions).

Twisted pair wire length is 238m (780ft as suggested by the maker: Gary, KD9SV, via emails). Average wire height is 1m. Located 154m away from the TX antenna. Thus, the length of RG-6U coax feedline (75 Ohm) should be doubled for two wire antennas connected to controller DXpedition Model II box from KD9SV, at hamshack. We used almost 900m RG-6U for feedlines.

At the preparatory stage, we changed the layout of this Beverage (from west to east into the north and south direction).That is because we found out higher noise floor level coming from power lines which is only 15m away routed parallel to the installation of a Beverage wire antenna to the west and east.

Later, the Beverage wire antenna was stretched out perpendicular to the power line. Immediately the noise level decreased. It performs even better when the feed transformers is put in new spot – far away from the towers and the TX antenna.

Because the antenna wire is floating above the contours of the valley, we could receive low angle signals (about 30-40 degrees, elevation). This antenna captured a lot of European signals. Tery, YC1KAF, operator, said that the noise in the antenna is much lower than on home-made Beverage antenna (30 degrees, azimuth). In all of our rx antennas, noise floor level is averagely S0. Only occasional static crashes that could pump up the S-meter to S3-5! Although we have had previous experience to build Beverage in our city-lot QTHs, most of us in the team never had such low noise experience.

b. Single Wire Beverage Antenna made by Danu, YD1GCL (yd1gcl.danu@gmail.com)

This was the main rx antenna used by YE1C in 2010. Then, it netted 122 JA stations on 160m, CW! I hope YE1C will soon be able to claim Worked All Japan Award (WAJA) 160m.

This antenna is made of insulated solid copper wire, type NYAF, 2.5mm diameter. Directed to 30 degrees, length 176m. The average height of 1.5 m from surface. Transformer 9:1 (Z) ratio is made of binocular toroid Amidon BN73-202. Located 100m from hamshack using 50 ohm coax feedline.

Figure 4. Beverage Feedpoint made by Danu, YD1GCL. Yellow wire to GND

Figure 5. Beverage antenna wire 30 degrees

The wire was deliberately elevated higher than the wire of reversible Beverage (see Figure 4 and Figure 5).
Based on the our experience in 2010, arriving signals from the JA-land (distance around 5000-6000kms) would always be strong even before the Sun Set (GMT) in Mount Malang. According to theory, at such times, the signal will come to us at higher angles. Apparently, the conditions of propagation to JA so bad that our forecast did not happen, but we felt there was nothing wrong with the plan whatsoever. This antenna is working optimally.

On several occasions, EU signals were skewed. The 30 degrees Beverage received better than the antenna 330 degrees. At least it reduced the CW tone severe intermodulations. This is found when I woke up and saw Joz, YD1JZ was on duty in the early morning. His ability to choose the correct rx filters, band pass tuning etc. on the Icom IC 7800 appropriately combined with the direction of the RX antenna had produced an optimal readability, weak signals were easily copyable.

Danu, YD1GCL, still stock some homebrewed feed transformers (9:1 Z) for the single wire Beverage that he never used.

c. RX 4-square array made of Lee, K7TJR. www.hizantennas.com/

Figure 6. Four-pole distance (in meters)

The full array system (vertical antennas, preamps, field control box, phasing delay lines, in-house controller, etc.) is also for the first time installed in Indonesia (see Figure 6). In our emails correspondence, Lee asked my reports of the usage. He mentioned, generally on MF, arriving signals in the equator zone is high angles. Where in more northern and stable area like in the U.S. and Europe signals travelled in a low angles.

On the advice of him, YE1C also installed full-sized low dipole with feedpoint as high as 10m above ground level, for RX.

Figure 7. Layout 4-square RX Antenna Array

We designed directions for the four elements array (in degrees) below. Identification on each array elements were numbered in sequence #1 to # 4 and made identical with the switch positions on the control box on hamshack (clockwise) so that the operator will not be disoriented in controlling it (see Figure 7, above).

1. north = 0
2. east = 90
3. south = 90
4. west = 270

This direction settings were designed to make the east and west elements as our default “ears” to receive signals from the Pacific and Africa. Unfortunately, during the contest, we did not hear the signal from Africa. Although, in the previous week we knew from the internet that K3QF operated XT2RJA (Burkina Faso, Africa) on 160m CW. According to my notes since 1997, this is the first time a station from XT2 QRV on topband.

Below is a plot of elevation of each element to 160m (from EZNEC) with a distance of 24.5m each side

Four directions of signal reception were very distinguishable when the control at hamshack is switched to the desired positions. Good indication of front-to-back ratio. We obtained this by monitoring the AM BC on MW band. So, since mid-day we already convinced this antenna works well.

Figure 9. Landscape of Gn, Malang to North Direction

Figure 10. Towers used for antennae TX YE1C

Being temporarily in enormous tea plantation area, we were lucky to have been able to explore the characteristics of both types of RX antennas in Mt Malang. For us, the Beverage antenna is magical because of its simplicity, but demanded estates. Whereas the 4-square rx antenna array from Hi-Z is innovative – a today’s optimum solution for topband DXer/contesters who lived in city lots. We firmly believed, both types can NOT be compared in apple-to-apple approach because of their different characters and the way they works.

Figure 11. Written instructions for the operator switches the RX antenna.

To facilitate the work of the each operator and the assistant – especially during sleepy times – in selecting nine RX antennas, we made written instructions (Figure 11) as a quick reference.

d. Coaxial-loop ala N6RK

The author had a chance to build the 80/160m coaxial loop RX antenna as derived from Rick, N6RK, concept. The height is 1 meter above the ground, and is located in QTH backyard, at 45m away from the TX antenna.

Figure 12. Coaxial Antenna loop-style 80/160m N6RK

Although it worked well, this antenna (Figure 12) was never used by operators YE1C because they preffered other RX antennas that provided them with more gain.

It is very true when the elders topbanders warned us that “you can not have too many receive antennas.” The meaning of that sentence is very wise. That said, do not become greedy operators who bought up all the DX at 160m, then soon go to retirement for DXing. However, it will also be difficult to implement too many rx antennas in a contest that demands other priorities.

In Mount Malang, West Java, I further understood that there are big differences in qualifications of being a DXer and a Contester on 160m. Gentlemen, what’s your position?

Y E 1 C

Persiapan dilakukan setelah menerima Surat Tugas dari Orari Daerah Jawa Barat No. 060/S-OPS/V/2010 Tanggal 25 Mei 2010 berdasarkan Surat Ketua ORARI Daerah Jawa Barat Nomor : 059/S-OPS/V/2010 Tanggal 25 Mei 2010 Perihal Partisipasi Kontes Internasional. Operator yang ditugaskan terdiri dari anggota ORARI Lokal Bandung Selatan dan ORARI Lokal Bekasi, karena sebagian besar operator yang ditugaskan adalah anggota ORARI Lokal Bekasi maka untuk memudahkan persiapan dilakukan oleh rekan-rekan dari Bekasi.

Target perolehan yang harus dicapai tentu saja ditetapkan dari awal, tetapi karena belum ada record untuk YE1C, maka kami memakai record YE1ZAT tahun 2009.

Persiapan dan seting stasiun dilaksanakan pada tanggal 27 Mei 2010, seting antena dilakukan oleh YD1JZ, YD1GCL, YD1ORZ, YC1KAF dan YB1CCF dengan fokus pemasangan antenna 40m dan instal N1MM Loging Contest terbaru terkait dengan perubahan Rule CQ WPX CW dan baru pada malam hari YB1KAR bergabung untuk membahas strategi dan pembagian jadwal tugas operator,

Antena yang dipergunakan untuk mengikuti kontes ini terdiri dari :

• KLM KT36XA untuk 10m, 15m dan 20m pada ketinggian 45m.
• Full Size Rotary Dipole untuk 40m pada ketinggian 40m
• Inverted V untuk 80m, feed point pada ketinggian 30m
• Inverted V untuk 160m., feed point pada ketinggian 35m,

biasanya pada stasiun ini memakai antena yagi 3 elemen untuk 40m pada ketinggian 30 m, tetapi karena sesuatu hal maka hanya dipergunakan single element saja dengan menaikan ke ketinggian 40m.

Perkiraan awal sebelum kontes berlangsung band yang akan terbuka adalah sampai dengan 20 m maksimal sampai 15m sehingga praktis hanya akan mendulang qso dari 3 band saja 15m, 20m dan 40m, sehingga akan fokus di 20m dan 40m.

Hari pertama 29 Mei 2010, ternyata perkiraan berbeda dengan real time 15m lebih bagus daripada 20m, sehingga start log dimulai pada band ini dengan log diawali oleh JR1NKN, jadi strategi kembali seperti strategi yang biasa diterapkan kalau rekan-rekan YE1ZAT berkiprah, mendulang qso dari JA stasiun di 15m. Beberapa kali pindah band antara 15m dan 20m karena sudah tidak lagi dibatasi oleh “10 minute rules” maka perpindahan band menjadi lebih nyaman. Pada jam 07:45Z ternyata 10m terbuka dengan baik dan membukukan 123 qso sampai dengan jam 10:49Z sebelum berpindah ke 40m band, sepanjang malam kami melakukan beberapa kali perpindahan band, jam 15:00z kami pindah ke 20m lalu jam 17:00z pindah ke 40m, jam19:00z pindah ke 80m, lalu pindah lagi ke 40m pada jam 21:00z, pada jam 22:00z kami mencoba pindah ke 160m berharap dapat qso dengan sesama YB-Land tetapi ternyata tidak terjadi dan hanya berhasil memperoleh 1 qso yang merupakan satu-satunya qso pada top band selama kontes belangsung yaitu dengan RW6HX, lalu pindah ke 20m pada jam 22:45z dan hari pertama log ditutup oleh VK2BJ dengan perolehan total qso 994 dengan penjaga gawang hari pertama adalah YD1GCL, YC1KAF, YB1CCF, YB1KAR dan YB1NWP.

Di hari kedua perjuangan terus dilanjutkan dengan start dari 20m band tetapi tidak bertahan lama pada band ini dan pindah ke 15m pada jam 01:00z, lalu jam 03:00z sampai dengan 04:00z mendulang JA di 10m sebelum pindah lagi ke 15m, pada hari kedua ini 20m kurang begitu bagus sehingga high band lebih fokus di 15m. Pada jam 8:20z pindah ke 10m untuk menhadang EU dan kembali ke 15m pada jam 09:20z sampai pindah ke 20m pada jam 11:55z lalu beberapa kali perpindahan band di 40m dan 80m sampai terkahir log di 15m dengan perolehan total 1.776 qso (dupe 7 qso) dan claimed score 3.924.074 point. Penjaga gawang pada hari kedua adalah YD1JZ, YD1GCL, YC1KAF, YB1ALL, YB1KAR.

Hasil perolehan score adalah sebagai berikut:
