Newbie in trial...

Hi all..after my last post for the past several months, i kept silent until today (8 July 2011), got some time to show up after busy with my working schedule. Time is killing me and it looks like i'm the busiest people in the world..Sorry not to say that i am very important person, but i'm sure that you guys can understand after we have passed a very busy day and you will feel like there is no intention to do "unimportant thing" like blogging. Huhuhu..So, last two months, i bought one very basic HF rig (Icom IC-718). Although i'm so busy with my outdoor programme but i have decided to buy cause it was my interest since i first involved in amateur radio (year 2008. So last two days..it was a lucky day (propagation), and i have a chance to qso at 28.490 (10 meter band) with 9W8WAT (Abg Wat) QTH Simunjan Sarawak and several more stations from Japan. Quite clear and easy to understand. So, herewith i attached the video that i have recorded. Thanks all...Just start HF..

QSO with 9W8WAT

I'm Back..

Hi all..so sorry for the silent..Almost a year i am not write anything to the blog. However, now I'm back to be apart of blogger. Actually have nothing to say, just to show several picture which i captured while attended for RAE 2010 (December) at Shah Alam. I'm not so sure how many candidate attended for the exam but seem so many peoples around. For visitors' information, i have started back my work last June and it gives me a bundle of burden to work with. Herewith i attached several pictures for your eyes..

Antenna Book

Hi all..just wanna share some information which i received from a friend of mine last 3 days. The book contain tremendous of variety in constructing home brew antenna for 2 meter band (144-148). So i feel it is worthy to have this. You guys may e-mail me if you akin to. So sorry because can not upload due to exceed in size permitted. The good thing about this book is the author provide a lot of design for 2 meter band. In addition, the author also provide measurement and material used for you guys to try it out. Those who can not download may e-mail me and I'll e-mail you the copy. Thanks to the author of the book for the brilliant and bright job. Until then, 73..

Trip to Melaka Zoo

Hi there.. So long not to update my blog..I'm quite busy with my study schedule. In the process of final writing of my thesis. A plenty of times have been spent in order to make it clear..Then on May I'll be back to Tg. Malim to continue my saltmine. However in my busy schedule, last two weeks my father and mother was here, so that i brought them hanging around Melaka town. Melaka Zoo is my choice this time since my harmonic always asking for it. In addition, the purpose of publishing this post is to promote the zoo to those friends who never come to this historical land. Melaka Zoo is among the top zoo in Malaysia. They also provide night safari to those who looking for something different. But i do not know how the feel is since i never join the night safari yet so far. So when we have time do come to Melaka and visit zoo or Taman Buaya which is just opposite to the zoo. To overseas visitor (my blog), it is worth to come to Malaysia cause we provide you a lot of thing to spend your holiday in Malaysia. So, herewith i attached a few pictures which has been captured along the way of my visit.

Just arrived..

Buaya Tembaga..worth to have because of the cooper..bole bikin antenna..hahaha

Small horse..Forget the scientific name..

Mr Hyppo..

Cow with long horn..

Elephant show..Beware: At the end of the session they will give you a present..free bath for visitors.

How is the data put on radio waves?

Hi all..to make my blog updated, since i am quit busy with my study schedules, i have tried to copy some informative page for visitors eyes regarding how is the data travel through waves. Maybe a lot of us still do not know how the data that we send everyday (voice, cw) work with waves including me until i found this article.
There are two common ways to put information in a radio wave, and you've likely run into them yourself. They are called A.M. and F.M. just like the two choices you've always known are on a radio. To understand these two ways of sending information it is important to know that radio waves, by themselves, have very regular patterns. Generally they keep the same amplitude or frequency all the time. (Amplitude is the "height" of the radio wave, frequency is how close the waves are to each other.)






A.M. stands for amplitude modulation. In this method, the information is put into a radio wave by varying the amplitude. For example, if all we wanted to do was send 1's and 0's, we could have just two different levels of amplitude that correspond to these numbers--1 being high, 0 being low.



F.M. stands for frequency modulation. This time the amplitude is kept constant, it is the frequency that is varied..



So ladies and gentleman, see how beauty and brilliants the creator up there..Think about it..Until then, see u in next post..73

Cerita Ghairah: Liana Memalukan Keluarga

"Sungguh memalukan!!"

"Maafkan saya bapak, sa..saya..saya menyesal!", Liana terisak-isak di hadapan bapaknya.

"Menyesal ? Dah terlambat! Kau tahu tak? Nama keluarga kita dah tercemar! … belum pernah keturunan kita kena macam nie? Kau tahu tak!" herdik bapak Liana.

"Sudahlah bang", mak Liana menyampok, "Kita bincangkan sekeluarga."

"Nak bincang aper lagi? … anak awak nie dah mengaku… … issshhh… … ." balas bapanya sambil memalingkan mukanya ke arah pokok di luar.

Liana betul betul menyesal dgn pengakuannya itu… kalau dia tahu bapaknya jadi camnie dia diam je… toksah mengaku lagi baik. Seluruh hidupnya seakan-akan runtuh di depan matanya, masa depan dia gelap? … dia telah mencemarkan nama baik keluarga dan keturunannya. Dia tahu masyarakatnya tidak akan dapat menerima dia lagi. Dia tahu keluarganya dah kecewa. What a letdown?

Di satu pagi yg hening dia keluar berjalan ke arah satu bangunan pencakar langit yg tinggi. Perlahan-lahan dia menaiki tangga sampai ke atas bumbung bangunan itu. Dia memandang ke bawah… dia lihat kereta dan org ramai bersepah kat bawah macam semut-semut yg baru kena spray dgn Baygon.

Liana dah nekad apa terjadi… . jadilah… .. Dia dah memalukan keluarganya, dia mencemarkan keturunannya, bapanya tidak mahu menerima atas kelemahannya itu.

Liana tebayangkan wajah maknya, air matanya menitis. Emaknya lah tempat dia bermanja, emaknya la yg akan meyelimutkan dikala sejuk, menyuapkan dikala lapar, wajah adik-beradik kembarnya juga terbayang dimata.

Sambil mengesat airmatanya, dia menarik nafas panjang… berjalan kehadapan hingga ke hujung bangunan itu. Setapak demi setapak dia melangkah ke hadapan hingga dirinya terjatuh melayang ke bawah… dia dapat rasakan angin yg begitu deras memukul mukanya… jantungnya berdegup pantas bila dia melihat bumi semakin dekat… .. dgn satu tarikan nafas yg dalam, Liana mengembangkan sayapnya, SWOOOOOSSSSHHHHHHHHH!!!… … .. dia terbang .

"Yessss! Yessss! Yessssssssssssssss! I’ve made it!!!!!", dia memekik keriangan.

Finally dia dapat melawan fobianya… dia dah no longer afraid of height… sebagai seekor burung, itulah yg sepatutnya menjadi fitrah semulajadi… selama ini dia takut… .. ye dia takut pada tempat tinggi dan kerana ketakutan inilah membuatnya tidak mahu terbang… dah bertahun dia rahsiakan hal ini dari keluarganya… . Sebab tu bapak dia kecewa bila dia membuat pengakuan itu kerana memang tak pernah seumur hidup seekor burung takut pada ketinggian.

Tapi sekarang dia dah tak takut, dia dah berani… . dia dah boleh terbang…

Friendship

Hi all..So long not to update my blog with my own word. Usually to make my blog update i use to copy any informative page from any other website for visitors eyes. However i do believe that those friends who ever visit here perhaps may get something from my post. Today i would like to write about friendship. The word that i really appreciate it when i realized how beauty the world is. Friendship isn't always easily described. The Eskimos, they say, have a hundred different words for snow. Unfortunately, the English language isn't quite as innovative, though it has vast opportunities to differentiate meaning. Certainly, Love is one of those opportunities. And so, too, is Friendship.

Instead of different words, however, we're stuck with simple adjectives. Close friend. Best friend. Childhood friend. Intimate friend. Trusted friend. Beloved friend. But whether you use adjectives or different words, few could deny the nearly infinite meaning in such a simple word.

Friends are special people. We can't pick our family, and we're sorely limited in the number of them at any rate. Society and mores (and often our own conscience) dictate we select a single mate. But our friends can be as diverse and infinite as the adjectives we choose. Our friends, in a very real sense, reflect the choices we make in life. So since we get involve in amateur radio as a hobby, of course we meet a lot of friends. Therefore, appreciate them as we appreciate our self. Until then..73

Radio Regions of the World

The International Telecommunication Union (ITU) divides the world into three radio regions. Frequency allocation to different radio communication services differ from region to region

What is "Skip Zone"?

Under the action of solar radiation and the hail of meteorites, an ionized layer is formed in the upper part of the Earth's atmosphere. In this layer, the neutral air molecules are decomposed into ions and electrons and the whole layer presents a chaos of charged particles.Short wave radio signals are reflected from this layer just as light rays are reflected from the surface of a mirror, or sound from a barrier.Likewise, this layer can be compared with the edge of billiard table: if the ball does not go straight into the pocket, it can be sent on rebound. In a situation, a radio receiver set located at a distance of 200 kilometres (say) away from the wireless transmitting station can not receive signals from the transmitting station. This is because the ground waves are stopped by the Earth's curvature and the sky wave will not reach the receiver, because it bounces again more than 200 kilometres way. So some 'blind zones' are formed and if the receiver is located in that blind zone it will receive no signal or very weak signal. In such a situation, another station can relay the message to the target station. The distance of the intended receiver from the transmitter is then termed as 'skip distance'. So it is not always necessary that a receiving station located nearer (than a station located further away from the transmitting station) to the transmitting station will be able to receive its signal.

IONOSPHERIC PROPAGATION

The First proclaimed Radio Amateur (HAM), Guglielmo Marconi was not using VHF or UHF for his famous Trans-Atlantic radio communication experiment nor was he employing any artificial relay mechanism. Yet his radio signal traveled half the world. Marconi's wireless transmitter powered by 2,000 volts from a generator driven by a 32 horsepower petrol engine pumped out 25,000 watts (25 KW) of power at a carrier frequency of about 328 kHz (Kilo Hertz). Alternately. the wavelength of the radio frequency used was approximately 915 metres. The formula to calculate wavelength of an electromagnetic wave is Wavelength in metres = 300/frequency In Mega Hertz. The dial of a radio receiver also marks either wavelength or frequencies or both.
On frequencies below 30 MHz, long distance radio communication is the result of refraction (bending) of the wave in the ionosphere. Oliver Heaviside in England and A.E. Kennally in America,in 1902, suggested that there must be some kind of reflecting medium in the upper atmosphere that caused the radio waves to be returned to Earth at considerable distances from the transmitter. Under the action of solar radiation and the hail of meteorites, an ionised layer is formed in the upper part of the Earth's atmosphere. In this layer, the neutral air molecules are decomposed into ions and electrons and the whole layer presents a chaos of charged particles.
Short wave or High Frequencies (HF) in the range of 3-30 MHz propagates through this invisible layer which consists of charged particles located at altitudes of between 250 and 400 km in the atmosphere surrounding the Earth. This layer of charged air particles called F2 layer of the ionosphere plays a vital role in HF propagation by reflecting or refracting the HF signals back to Earth.
The ionosphere has got different sub-layers. The lowest is D-layer at altitudes ranging from 50 to 90 km. High frequencies (3-30 MHz) penetrate this layer, while low frequency (LF: 30-300 kHz) or medium waves are absorbed by this layer. To some extent LF and Very Low Frequency (VLF: 3 to 30 kHz) are reflected during daytime. It slightly scatter and absorbs HF. This layer subsists only during daytime.
The E-layer extends from an altitude of 100 km. Though sunlight is an important factor for its existence, after sunset also it exists for some time. This layer is responsible for evening and early night time propagation of medium waves (low frequency) upto a distance of about 250 km. Propagation of lower short wave frequencies, e.g. 2 MHz , up to distance of 2000 km at daylight time is due to this layer. It has little effect at night.
F1 layer exists at an altitude of 200 km during daytime and its characteristics are very similar to E-layer which emerges into F2 layer at night. F2 layer is the most important layer which exists at altitudes ranging from 250 to 400 km and HF long distance propagation round the clock is due to this layer. The behaviour of this layer is influenced by the time of the day, by season and by sunspot activity. F2 layer was formerly known as Appleton layer. This layer has a high ionization gradient. This layer exists both in the daytime and nighttime. Since at such an altitude air density is extremely low, the free ions and electrons (due to the action of ultraviolet radiation from the Sun) can not recombine readily and so can store energy received from the Sun for many hours; that is the reason the refractive property of this layer changes only to a negligible extent during day and night. The path which the short wave signal follows through the F2 layer is in reality a curved one. Degree of the curve depends on the angle of incidence of the wave, ionization gradient of the layer and frequency of the signal.

What is VHF?

The radio frequencies above 30 MHz has the tendency to penetrate the ionosphere making them unsuitable for long distance propagation. So, the range of frequencies from 30 to 300 MHz (also 300 MHz and above), which are placed under the Very High Frequency (VHF) category are mainly used for line-of-sight communication. The most common example of line-of-sight communication is the TV Telecast. A TV transmission tower is made as tall as possible so that its signals can have a wide area of coverage. To receive a TV telecast, we have to turn our TV antenna (known as a Yagi antenna) towards the TV transmission tower. In areas where the TV transmission tower is located at a far away place from a viewer, the viewer has to increase the height of his TV receiving antenna. This means that both the transmitting and receiving antenna should literally see each other to make the communication effective. Otherwise there should be some means to redirect the signal back to the receiver. Artificial Satellites in space (which houses active electronic relaying device), terrestrial relay station and passive reflectors (the metallic plates we see above the hills) are employed to extend the VHF coverage. Line-of-sight communication is considered reliable within a short distance.

Selamat Berpuasa dan Kemerdekaan ke-52

Salam untuk semua rakan..Menjelang bulan baik dan mulia ni, kita seharusnya bersyukur kerana masih lagi dipanjangkan umur untuk merasai nikmat berpuasa bagi tahun ni..Alhamdulillah..Seronok melihat kemeriahan di bulan puasa samada pada waktu malam maupun siang hari terutamanya di pasar ramadhan..hahahah..mungkin sesetengah kita masih teringat bagaimana meriahnya masa kita kecil apabila tibanya waktu berbuka..Segala makanan yang dibeli sewaktu di pasar seakan-akan ingin ditelan sekali gus..Tapi..bila minum je air 2 gelas...semua makanan tolak tepi..ni bukan budak2 je yang alami..sindrom ni aku rasa akan menyerang xkira siapa..kanak2 mahupun dewasa.Janji ikut spesifikasi yang ada iaitu "lapar mata". Bulan ni jugak aku rasa beruntung kerana bulan Kemerdekaan turut jatuh pada bulan Ramadhan. Semoga Malaysia terus maju dan cemerlang. Cuma kadang kala aku terfikir apa maksud kemerdekaan bagi setiap rakyat Malaysia. Setiap kali malam merdeka pasti akan ada situasi seperti undang-undang jalan raya seperti tidak wujud pada pandangan remaja. Mereka akan memecut dan melakukan pelbagai aksi2 yang mengerikan dan ku kira amat BODOH..Malam merdeka yang lalu aku bersama rakan-rakan ham Melaka di Restoran K5 di Semabok, Melaka. Situasi yang sama turut berlaku menyebabkan ketidak selesaan dalam kalangan pelanggan restoran dan kami..Apa pun sama-sama lah kita mendoakan agar generasi pewaris akan datang tidak akan menjadikan gejala ini sebagai sebuah gejala baru yang harus dialami oleh setiap remaja. Akhir kalam selamat menjalani ibadah puasa dan selamat menyambut hari Kemerdekaan yang ke-52, semoga tanah tumpah darah tercinta ini akan terus maju dan maju..Merdeka, merdeka, merdeka!73

My 9 Elements Yagi Homebrew Project

Hi again..Today i'm quite free and would like to share with those reader who visit this 'funny' blog. My latest homebrew project is 9 elements Yagi. So far i still do not test the performance of that antenna because of time constrain and no suitable pole to erect the antenna. However based on the SWR ratio that i have checked, the performance was so good at 145-148 Mhz..The length of the antenna is quite long.


In the process...9 Element Yagi

Still in progress..




Done...9 element Yagi
The boom is about 3.5 meter. A bit long and need more free space to erect the antenna. I wish to put on 20 feets pole and raise it from ground level. This is because as we know the nature of Yagi is directional. So without any rotators i have to swing it around to find the most strong signal. Those who interested to check for the diagram may browse it to http://users.belgacom.net/hamradio/homebrew.htm. They provide a variety of diagram to those who happy in homebrew..Cheers 73

V24 Close Up

On the tip of 20 feet pole on my base station roof.

My antenna base station

My antenna base station:
Brand: Antenna Silver V-Two 4 Special
Radiation: Omnidirectional
Frequency range: 142-148 Mhz
VSWR: 1:1.5 max
Maximum Power: 200 Watts
db: 9dB, 11.1 dBi
Length: 18 feets

v24 Special Review
My homebeli antenna base station. So far the performance is quite good. I do simplex with 9W2TGA bang Rosli Manjung on v32 with full blast of power output. My transceiver is icom ic v8000. I can listen to 9w2tga in r4 with busy mood. Just for 3-4 over then the propagation was closed. Another dx contact station is JZ04BDP Bang Power from pekan baru indonesia..He can received me well (r5 s3) with 25 watt power output. The most far dx station i think is YD6STO handle Sutikno from Sumatera Utara, Indonesia. I do not know performance of other antenna, but my colleagues always suggest me to use diamond x510. So far i do really satisfied with this v24 special performance. Those who wanna try may contact 9w2tga. The price is quite cheap compared to another antenna since the performance is quite good too. With RM280 you may own one. My intention is more on dxing and try to contact with another station who stay really really far away from my base station. By using this antenna, Kuala Lumpur is very near to me. As low as 5 or 10 watts i may contact with 9w2uaw Bang Nuar in Cheras. The dB is quite high compared to another antenna. Normally we may have this number of dB by using Yagi antenna with certain element. However it depends on you guys..Tepuk wallet tanya selera nak antenna mana...hehehehe..73

Here we come..."CW MINI MARKET" dah di dah dit...

Salam again..Hi all..Those who wanna learn or train CW, please do come to this market..Hahaha..Just kidding..The mini market is just nearby to my base station. At first sight when i look at the signboard of the shop i was wondering where did the CW's name come from. So when i approached the owner without asking anything, then i know the answer. The owner is Chinese..So you also know guys...73

Life is quite busy

Salam again..Life is quite busy lately..As usual, i keep travelling from Melaka to Shah Alam since my 'long holiday' is finished. It is too long I'm not engage in this blog. However, the true story is that, to those who ever visiting in this blog, many sorry because this is just my trial blog page. I'm not keen to stay as my permanent blog. The funny thing is that, i do not know how to build my own blog. Hahaha..Until today, i have tried to revisiting this 'funny' blog then i found there is 1 follower. My fellow friend 9w2DXN. Thanks bro for the joining and visiting this. what ever it is i appreciate that. Maybe i can learn more regarding how to reconstruct this 'funny' blog from you. Hopefully.. Many sorry also because of this 'busy life' has scratched anyone..i'm not being able to join on the day where Local repeater-Astra Melaka officially function. What ever it is...I wish tremendous congratulation to all ham in Melaka for such a great effort. Until then..See you again..73
