Terapung sama hanyut, terendam sama basah...



Terima kasih diucapkan kepada 9m2get op Hairie diatas rakaman yang telah dilakukan olehnya, rakaman ini diambil semasa aku sedang dxing di 40m. Pada masa itu aku hanya TX dengan kekuatan 50 watt dan G5RV JR. G5RV JR ini aku pasang betul-betul menghadap ke 274 darjah Barat iaitu menghadap QTH 9m2get di Arau, Perlis. Mungkin inilah faktor mengapa db tinggi di Arau. Apa pun, terima kasih sekali lagi diucapkan kepada Hairie 9M2GET di atas kesudian merakam aksi aku di udara.

Jumpa dan jumpa lagi......73 9m2zak

Japan scraps Morse test

Japan scraps Morse test

The Japanese Ministry of Internal Affairs has decided to scrap Morse telegraph testing for the Amateur Radio Class 1 and 2 licenses with effect from October 1, 2011.

A public consutation on the Morse test was held earlier in the year to which 39 people responded. Following the consultation the Ministry announced that Morse telegraphy testing would be discontinued.

Japan pioneered the HF No-Code Amateur Radio license (Class 4) in the 1950's although they still required Morse for the higher license classes. The written exam for the Class 4 is roughly equivalent to the Foundation exam in the United Kingdom and Australia and the discontinued USA Novice.

Passing the Morse code test

The Morse code test is very basic, you listen to 10-7 minute of code from a computer and write down what characters you hear. The test goes something like this:
  1. Test administrator starts the computer and you get 1-2 minute of practice code before the real test begins. Be sure that you can hear the code generator clearly and let the test administrator know if you cant. Sometimes strong echoes interfere with the code, so dont be afraid to have the equipment adjusted or move around until you can hear clearly. Take advantage of this time to relax and get comfortable. Dont worry if you dont copy the practice minute well, use the practice to get rid of your jitters.
  2. Verbal instruction are given for the actual test code by the tester. Follow the instruction carefully despite the adrenaline coursing through your veins.
  3. 6 V characters (meaning test) are sent.
  4. The actual test begins and continues for at least 7 minute. The code contains text and numbers in two session. First session : anything from plain Bahasa Melayu. Second session : Random groups of number.
Like written exams, you can take some easy steps to make your Morse test easier...
  • Dont : practice at very high or very low speeds, stay just a little faster than the test speed. ( 16-14 wpm)
  • Do : have at least one spare pen or pencil ready to pick up and use.
  • Dont : erase any miscopied characters, just make a single line through them.
  • Do : Leave an underscore when you miss a character, like_this, because you may recognize the word as you copy more letters. Making underscore for each missed character keeps you in rhythm until you get back on track.
  • Dont: Panic when you miss a character. take a deep breath and focus on an upcoming character.
If u didnt make it, dont be disheartened. Many sessions allow you to take it again. Dont let a failure stop you! Many hams make more than one attempt to pass a test and they are on the air today.

Hope to see on the bands

5 watt qrp qso...

Hari ini amat bermakna sekali bagi aku. Ini adalah kerana setelah seharian bergelumang dengan pen dan kertas, aku melepaskan semua tekanan itu di cw key besi aku. Apa yang menariknya, kali ini aku bekerja hanya dengan 5 watt sahaja.



Pada mulanya, aku dengar satu stesen dari Thailand, E21ejc sedang cq di 7004, kedengaran signalnya begitu cantik sekali...tiada qrm...tidak over modulate...solid....tidak splatter ke frekunsi sebelah...hanya terbabas sekitar 2-3 khz sahaja. Manakala kalau stesen-stesen yang lain sampai terbabas sehingga 10-15 khz. Confirm...dia sedang qrp...tapi berapa watt aku pun tak pasti...



Pada malam tadi, band 40m membuka dengan cantik sekali, tak tahulah kalau tempat lain sebab di qth aku signal noise sekitar s0-s1...cantik bukan? Jadi tak hairanlah kalau rakan kita dari negara gajah ini boleh qrp. Jadi aku pun hulur dengan 5 watt... terus dia reply...secara automatik dia reply...ini bermakna dia dapat copy signal aku dengan baik. Dibawah ini sedikit qso yang dicatit dari buku cw qso book aku...

SKCC


9m2zak skcc setup

Straight Key Century Club, sebuah kelab yang memperjuangkan penggunaan cw key. Dimana semua ahlinya menggunakan straight key untuk berhubung. Boleh dikatakan masih lagi menggunakan cara tradisional...tapi jika difikir-fikirkan baik juga mereka menubuhkan kelab ini.Ini adalah kerana nanti straight key ini akan hilang di telan zaman atau dilupakan kerana kemunculan Lambic yang semakin popular penggunaannya. Memang tidak dapat dinafikan lagi bahawa kelajuannya tidak setanding paddle key, tapi ingat....tanpa straight key maka tidak akan lahir lambic yang ada sekarang ini. Jadi ianya tidak harus dilupakan dan ditinggalkan....

Atas kesedaran itulah aku menyertai kelab ini. Tidak dikenakan apa-apa bayaran cuma anda perlu menghantar email dan menyatakan kenapa anda ingin menyertai kelab ini. Jadi kena buat karanganlah...hehe. Syukur kepada tuhan, permohonan aku untuk menyertai mereka diluluskan dan aku diberi sijil penyertaan dan no id sekali. SKCC #7660

Petang ini aku bekerja dengan satu stesen dari Australia...tapi kali ini ianya berbeza sedikit kerana sebelum kami bekerja...kami akan chat dulu kat sked page...sebenarnya ia adalah salah satu aktiviti SKCC iaitu Straight Key Century Club. Dimana ahli-ahlinya akan mengadakan temujanji untuk bekerja bergantung kepada keadaan band. Syukur petang tadi aku dapat bekerja dengan VK4TJ, John. Dengan hanya kekuatan 20 watt kami dapat bekerja dengan baik sekali kerana fre yang digunakan itu sememangnya tersedia khas...jadi tiada gangguan....Difahamkan juga kita boleh deal dengan mana stesen seluruh dunia untuk test qso dan test propogasi...Secara tidak langsung kita dapat tahu keadaan propogasi sebenarnya.

Kuat juga.....

Kuat juga signal noise sejak 3-4 hari ni. Terutama bagi band 40m - 20m. Tak tahulah apa bacaannya kalau disebelah petang sebab aku hanya monitor sekitar jam 11.00 mlm ke atas. Maklumlah bila dah mula lombong garam ni, dia punya bz lain macam sikit....biasa la awal-awal tahun.
Tapi bila moni kat 40m signal yang masuk dia lain macam sikit macam tahun lepas. Maksud aku pada sekitar Nov dan Dis. Malam tadi signal noise mencapai s9 dan pernah stabil kat s9....ulang balik..stabil kat s9. biar betul...kalau macam ni nak dengar apa? tak tahu ianya hanya berlaku di qth aku sahaja. Kena renungkan faktor-faktor lain. Mungkin ada orang atau jiran sebelah menyebelah aku menggunakan blender? mungkinkah ada gangguan statik yang dari PC aku? ataupun dari power supply. Mungkin juga dari microwave jiran? Kesemua element-element aku teliti dan teliti dan yang pastinya bukan dari sumber tersebut.
Aktifkan NB pada rig......tiada perubahan....aktifkan RF ATT...ada perubahan...ia turun sampai S3 tapi sebenarnya ia mengurangkan kekuatan signal sahaja...bukan menyelesaikan masalah...pusing ke band 80m....pun sama....pusing ke band 30m pun sama jugak...kemudian patah balik ke 40m...tiba-tiba kedengaran stesen dari Hungry sedang cq...hmm...ada signal masuk...cuba hulur sekali....dan terus dia respon...HA8RM 599 signal dia...sama kuat dengan signal noise tadi. kemudian pusing lagi tombol..jumpa plak stesen dari Slovenia S53MM 599 jugak.
Kesimpulannya malam tadi band memang tutup atau dead sekitar 11.00mlm hingga 12.00 mlm. Patut bang ody takde kat cluster, begitu jugak orang Arau...hehe..suis off itu rig, cabut coax, cabut plug dan terus tidur...

Theodore Roosevelt McElroy World's Champion Radio Telegrapher The Man, The Legend and The Keys

Mac-Key in action

Theodore R. McElroy lives on, almost 40 years after his passing. His ability to copy code made him a legend in his own time and the keys he made serve as reminders of his accomplishments. The photo at the left was taken in a Life Magazine photo op in 1962 and shows McElroy with his American Morse practice sets. Notice the Prince Albert can in the resonator box!

Born in Boston in 1901, Ted went to work for Western Union as a messenger boy at age 14. The telegraph operators taught him American Morse and by age 15 he was working the wires. During W.W.I he was a civilian operator at Camp Devins.

Shortly after the war, McElroy went to work for WSO, one of RCA's transoceanic wireless stations. There he worked the Morse wires until he learned the International Morse code used in wireless work. Until 1920 he worked the wireless circuits to POZ in Nauen, Germany and LCM in Stavanger, Norway, keying the giant Alexanderson alternators on 20,000 Meters. Ted stated that the signals were so strong that it was almost liMcElroy Bugke working an "iron wire." Ted returned to Boston to work for Western Union once again.

In 1922 McElroy entered his first code copying contest and won hands down, winning at a speed of 56 words per minute (WPM). From then on he was untouchable. He was beaten in 1934, but regained the championship in 1935. At his last official competition in 1939 in Ashville, North Carolina, he won with a speed of 77 WPM. This Continental code record was untouchable for almost 60 years and was only recently challenged. Ted also was the American Morse code champion and Japanese Kanji code champion.

Ted's phenomenal success at copying code was due in part to this ability to type. He could type 150 WPM as recorded by his seventh grade typing teacher! He remarked once that he could type three letters for every letter that his secretary typed. Needless to say, he also won typing contests.

In 1934, Ted started his own business manufacturing telegraph equipment. The first key to come out of the McElroy factory was called the MAC-KEY. The base, mainframe and posts were a one piece casting. This design helped to eliminate vibrations and the need for frequent adjustments. The "Tee-Bar" across the top of the frame served several purposes. First it was an integral part of the frameMcElroy Bug, Deluxe Model holding the trunion pin. Second, it provided a convenient means for the professional operator to carry his key to and from a shift. The fingers were merely curled under the bar and the key lifted. Third, though probably seldom used, it allowed the key to be turned on its side; once the pendulum was locked with the damper post clip, the MAC could be used as a hand key.

Many MAC-KEYs were made. The topmost image is the third variation introduced in 1936. They were heavy and rugged and once adjusted required little maintenance. Many MAC-KEYs are still in service today. One of McElroy's many refinements, was his "dot stabilizer." This was a small assembly fitted to the pendulum, which pre-loaded the dot spring. This slight amount of pre-loading gave smoother and better weighted dots, while eliminating contact bounce.

The MAC-KEY was the first of many models. In 1937, a modified design was introduced. Several of the new models were advertised in the December 1937 issue of QST. These keys were labeled with an inscription attesting to the skill of the maker. See the image at the left. The top of the line model had a simulated marble finished base and chrome upper parts. This Deluxe model, shown above, sold for $9.50; wouldn't you like to find one today for that price! The Standard model had a black wrinkle finish and nickeled upper parts. It sold for $7.50. The Junior Model, very, very rare, had the same working parts as the Standard model, but was on a stamped steel base and sold for $4.95.
McElroy Bug Label

Even though other manufacturers were doing so, McElroy preferred not to make a chrome based model. "I know as an operator of about 25 years experience that it is very poor practice to have a chrome or nickel plated base on a key. Light reflection from such a base is a severe strain on an operator's eyes." This was so stated in a McElroy flyer dated 1938. Ted would later go against these very words. Read on! There were also four models of hand keys ranging in price from $1.20 to $2.25.

Just before W.W.II, the famous McElroy "teardrop" bug appeared. These keys are popular collectors items because of the unusual shape of the base. The "art deco" base resembles a flatiron or tear drop. Some operators called them "flatiron" bugs. The "teardrop" was available with platinum contacts for the very competitive price of $11.85. The model with silver contacts was slightly less. Many CW men thought McElroy's sanity should be questioned because of the unconventional design. However, in spite of all the cat calls, this was one of the finest handling semi-automatics built. The "teardrop" bug shown in the in the image saw duty on a DC-3 flying Pan American routes. It isMcElroy teardrop Bug often forgotten that commercial aircraft has a Flight Radio Officer of FRO as they were called. Notice the suction cup feet on this bug that keep it on the FRO's table. The teardrop shaped hand keys also appeared at this time. Two models, one with a metal base and one with a plastic base are shown below. The key with the plastic base has raised letter with a testimonial similar to the inscription on the bug label shown above.

In the late 30s, McElroy traveled the country giving code copying demonstrations. He loved to put on a show and thrived on attention paid to him.. One of his favorite tricks was to stop in the middle of a high speed run, drink a glass of water, and resume copy without missing any text. Ted was in Dallas in 1939, putting on a demonstration of his remarkable abilities in front of the Dallas Amateur Radio Club. Afterwards, he opened a case full of keys and sold a bunch of them. McElroy worked with noted code instructor Walter Candler, giving demonstrations and teaching the "Candler Method" as advertised in QST.

During W.W.II, Ted made telegraph apparatus for Uncle Sam. Ted and his "gang" produced more such gear for the Allies than any other company. They received the Army - Navy "E" Award for excellence and were able to complete many contracts ahead of schedule. Ted rewarded his "gang" with partiesMcElroy Hand Keys and jam sessions. Morale was high and the employees had fun. McElroy even made J-38s, the famed bakelite based key made by many contractors for the Army during W.W.II.

After the war, McElroy continued to manufacture automated high speed telegraph apparatus. A former employee related that Ted could adjust the instruments sending at a speed of 100 WPM, when others in the factory had to use an oscilloscope! In 1955, he sold the company and went into semi-retirement. He later became a manufacture's representative and even dabbled in local politics. It is said that during this time, Ted liked to give telegraph keys to his friends as gifts. He passes away in his native Boston in 1963.

As long as there are those that are interested in the code and keys, McElroy the man, the legend and his keys will be remembered.

Never send faster than you can send accurately

Quality Of Sending

Quality must always come first, and speed second. Aim to make your sending as nearly perfect as possible. Smooth, uniform characters and spacing penetrate static and interference far better than individual sending styles. We should learn to send so clearly and accurately that the receiving station gets perfect copy every time....

Video ini diproses menggunakan perisian Movie Maker yang boleh didapati secara percuma dalam XP. Manakala audio pula dirakam dengan menggunakan perisian Ham Radio Deluxe Version 5.0 Beta yang percuma juga dan boleh didapati dalam internet.

Antenna yang digunakan semestinya DAL 2 element monoband yagi dan antenna ini dihalakan ke arah 30 darjah Utara. Kenapa ke utara? sebab pada arah tersebut kita boleh dapat pelbagai stesen dari serata dunia seperti Amerika Utara, Amerika Selatan, Asia Tenggara, Asia Pasifik, Eropah dan banyak lagi. Tapi ingat, itu semua bergantung kepada keadaan propogasi.

Kuasa atau power pemancaran yang digunakan ialah 30 watts, pada mulanya ingin memancar pada kekuatan 5 watt ( QRP) tapi memandangkan kadar kebisingan yang tinggi ( signal Noise) sehingga S4-S5 maka kuasa pemancaran dinaikkan ke 30 watt. Insyaallah jika keadaan band baik, tiada bunyi bising yang tinggi serta senyap, semestinya aku akan beralih ke mode qrp kerana ianya mencabar sekali. Siapa yang tidak suka pada cabaran.

Rig atau radio yang digunakan ialah FT 77. Rig ini amat bagus sekali bekerja dan ianya berfungsi dengan baik sekali tanpa masalah. Apa yang menarik tentang FT 77 ini ialah terdapat lubang REC yang berfungsi untuk merakam aksi semasa diudara tanpa melibatkan fungsi phone. Ini bermakna kita boleh merakam sambil mendengar. Kipasnya yang akan hidup dengan sendirinya jika suhu pada rig tersebut meningkat. Kesemua fungsi asasnya berjalan dengan baik seperti RF ATT, NB, AGC, dan MIC DRIVE.

Kelajuan yang digunakan semasa ke udara adalah sekitar 18 wpm - 20 wpm. Pada kelajuan ini, berasa amat selesa sekali dan ianya lebih santai dan tenang. Kenapa perlu nak laju-laju, yang penting sekali ialah rakan kita dapat menerima dan memahami setiap ayat yang kita hantar. Tidak guna hantaran laju jika setiap butirannya tidak difahami. Jaga Spacing dan rentak, kalau boleh ada ritmanya sendiri agar senang untuk diterima dan sedap telinga mendengarnya. Secara tidak langsung ianya akan menjadi tanda pengenalan cw anda sendiri. Lama kelamaan orang akan mengenali anda tanpa mendengar callsign anda, hanya dengar cara anda cq pun sudah tahu siapa gerangannya......

jumpa dan jumpa lagi.... 73 de 9m2zak

Homebrew Single Lever Cw Paddle


Salam ketemu lagi rakan-rakan sekalian, post kali ini berkaitan dengan homebrew, homebrew cw single lever paddle. Cetusan idea untuk menghasilkan paddle ini adalah kerana penat mengejar rakan-rakan semasa qso dimana mereka boleh dikatakan hampir keseluruhannya menggunakan paddle samada single atau double. Bagi aku yang menggunakan batang besi lurus ni, tak ubah macam kura-kura dengan arnab, tapi sebenarnya sampai jugak, maksudnya dapat copy jugak pancaran aku.

Setelah membuat sedikit kajian di internet, maka aku mengambil keputusan untuk menghasilkan single paddle sajalah kerana ianya amt senang sekali dan boleh dikatakan ianya menggunakan barangan terbuang. Secara jujur aku katakan yang projek aku ini tidak mengeluarkan sekupang pun. Semuanya menngunakan barang-barang yang berada dalam shack aku ni, itu pun setelah berjam-jam menggeledah laci-laci dan kotak-kotak simpanan barang permainan aku ni.
Antara barang yang diperlukan untuk paddle ini ialah :
  1. Sekeping mata gergaji besi, kalau ada besi lain pun boleh jugak, tapi ianya mestilah elastik.
  2. 4 penyambung bucu meja yang berbentuk L
  3. 4 batang skru
  4. wayar 3 core
  5. stereo audio jack
  6. wayar conector
  7. sebongkah kayu, saiz ikut suka
  8. Minat yang tinggi
Proses untuk menghasilkannya hanya mengambil masa 30 minit sahaja dan ianya berfungsi dengan baik sekali. Sebenarnya pada mulanya tiada bunyi yang terhasil kerana bilah gergaji besi tu aku tak gosok untuk hilangkan catnya. selepas digosok sedikit pada bahagian contact pointnya, ianya berfungsi dengan baik sekali. Anda boleh tengok video ini.





Paddle ini akan aku gunakan semasa cqcwww nanti. buat masa sekarang aku sedang giat berlatih untuk membiasakan jari jemari supaya selesa dan ngam dengan mata bergaji ini. Lupa plak, sebelum pasang mata gergaji tu, sila tumpulkannya dulu supaya tiada yang cedera parah nanti.

Disini aku lampirkan contact yang telah berjaya aku dapat dengan menggunakan mata gergaji ini.
