Radio Amatur Dan Kelab

Amateur radio is the use of designated radio frequency spectrum for purposes of private recreation, non-commercial exchange of messages, wireless experimentation, self-training, and emergency communication. The term "amateur" is used to specify persons interested in radio technique solely with a personal aim and without pecuniary interest.

  • What is pecuniary ? if you are saying that you are an amateur radio without knowing or understanding english, better you rethink your phrase again.
  • Jikalau anda mengaku bahawa anda seorang radio amatur tetapi anda tidak memahami bahasa inggeris dan tidak cuba berusaha untuk belajar, lebih baik anda pikirkan semula.

Pecuniary is an adjective:Of, relating to, or consisting of money.

-------------------------------------------------------------------------------------------------------------

Kemunculan pelbagai kelab dengan pelbagai objektif sebenarnya ada buruk dan baik. Kelab tertua di Malaysia adalah MARTS, dan kelab paling ramai ahli adalah ASTRA. Tidak dikira lagi dengan kelab-kelab berdaftar dan tidak berdaftar negeri, daerah dan juga "kelab lanun". Banyak callsign kelab dikeluarkan, tetapi tidak ramai ahli kelab yang berminat untuk mengoperasikan callsign itu di semua jalur yang telah dibenarkan kepada kelab. Kelab dapat mencorakkan ahli-ahlinya bergantung kepada pemimpin kelab itu sendiri. ke kanan pemimpin itu, ke kananlah ahlinya, ke kiri ahli itu maka ke kirilah ahlinya.

Kelab atau persatuan menghimpunkan manusia, tidak kira apa pekerjaan, latar belakang, kelas, dan juga bangsa. Tetapi, ada juga kelab yang menjarakkan manusia mengikut agama, bangsa dan juga kewarganegaraan. Kelab seharusnya berdaftar dan juga berdisiplin serta mengikut tatacara yang sepatutnya. Ahli perlu memain peranan masing-masing, dan sepatutnya tau objektif sebenar kelab itu sewaktu mereka mendaftarkan diri pada awalnya. Perlembagaan dan perundangan perlu dikajiselidik supaya tidak berlaku ahli  "zombie" di dalam kelab itu nanti, pendek kata ada tetapi macam tidak ada, tidak ada tetapi ada.

Kelab-kelab yang beroperasi di HF sepatutnya perlu dikawalselia, station master seharusnya memerhati dan memberi tunjuk ajar kepada mereka yang belum pernah bekerja di HF terutama tentang hal-hal keselamatan. Ini adalah kritikal, kesilapan boleh membawa padah. Ada kelab yang mendapat penguntukan untuk bekerja di HF, tetapi ramai pemimpin ahli itu sendiri tidak berminat untuk bekerja di HF. Pada pendapat saya, agak rugi mereka tidak guna apa yang mereka beli.
The granting of a separate license to a club or organization generally requires that an individual with a current and valid amateur radio license, who is in good standing with the telecommunications authority, assumes responsibility for any operations conducted under the club license or club call sign. A few countries may issue special licenses to novices or beginners that do not assign the individual a call sign, but require the newly-licensed individual to operate from stations licensed to a club or organization for a period of time before a higher class of license can be acquired.
cuba kita semua fahami apakah maksud frasa yang telah dihitamkan itu. apakah itu any operations ?

Seperti yang kita semua (tidak semua) maklum, operasi radio terdiri dari beberapa mode. Antaranya adalah mod suara (SSB,AM,FM,etc), mod digital (PSK,RTTY,etc) dan juga mod CW (Continuous Wave) atau kod Morse. Net atau rangkaian juga boleh dikatagorikan sebagai operasi. Directed net, asissted net dan juga round robin net. Rangkaian boleh berubah mengikut keadaan sebagai contoh rangkaian sewaktu kecemasan adalah berbeza dari rangkaian perbualan biasa.

Callsign kelab di Malaysia adalah bermula dengan prefix 9M4 tetapi ada juga yang bermula dari 9M2, terutama kelab-kelab lama. Tetapi ada juga kelab baru yang menggunakan callsign 9M2, atas dasar tertentu dengan secara tidak lansung melanggar guidelines yang telah dikeluarkan oleh MCMC (dengan rela)


Jika anda sedang mengikuti sesuatu acara kelab, cuba selidik siapakah "who is in good standing with the telecommunications authority, assumes responsibility for any operations" ini ?

amateur radio - if you don't understand English and you are not taking responsibility to learn it then you better seek another hobby.


Procedures

Definition of procedures, a procedure is a series of actions or operations which have to be executed in the same manner in order to always obtain the same result under the same circumstances. In telecommunications, this is the premise under which a SOP (Standard Operating Procedure) is generated.

GOOD OPERATING PRACTICES AND PROCEDURES

GOOD OPERATING PRACTICES AND PROCEDURES FOR THE HAM BANDS

Presented by Tim, AJ4D

As I fade from the VHF/UHF bands back to HF, I hope I can share some of the things that really might help other operators become better operators.

I am not the best in the world. I make mistakes on HF that most new hams would not make.

Even on VHF, I sometimes "get in a big way of talking" and forget to ID on time.
But, below are some of the things that might help everyone out somewhere down the line, QSL ?
( just had to throw that in there to show how stupid it looked ).

I really believe that the reason a lot of the new hams don't operate as much as they could is that they simply cannot figure out what the heck is being said!! It makes them afraid to talk.

The other thing is that some operators on repeaters have their own little "group" and that little group is the only one they will respond to or talk to. I hear so many new callsigns being correctly " thrown out' on repeater frequencies and no one goes back. I try to jump in and talk to them if no one goes back to them by the second try.
It makes them feel left out, looked down upon , and more like giving up on the HOBBY than anything else when they hear people talk for 30 minutes and then when they get the courage to key up, no one comes back!
What happened to being courteous!
I truly believe that is the reason there is not that much traffic on repeaters now. Why should 2,000 operators in East Tennessee keep trying over and over for days to get someone to talk to them or sit there and listen to a bunch of garbage that they have never heard of?
Remember guys and gals.....you're the "Elmers" and teachers of the newer hams!

Get on there and tell the new ham,

"Good to hear you, just get on here and if you talk on it like a telephone in plain english and ID every 10 minutes with the repeater ID timer, and sign off by saying your ID , you will learn a lot from the people on here and will be made to feel welcome".

The last paragraph above in bold text sums up how to talk on a repeater in one sentence.
This is what I was told on the 147.255 when I tried to pick up some of the bad habits and lingo that some of the idiots were using at the time. It only takes one time to tell a new ham the one paragraph above that will make them sound and feel much better on any and all repeaters.

See "A New Ham's Guide To Repeaters" for a basic understanding of how repeaters work on another page.

Procedures on radio:

It is stressed that emergency traffic always has priority. If it aint there, dont ask for it on a net or any other time!
On so many nets on so many repeaters, AND EVEN ON HF, when they start up the net; they usually say "is there any emergency traffic?"..... sort of like asking,
"Is there anybody out there that has quit breathing, or someone next to you having a heart attack, or someone in front of you in traffic that has had a wreck and is entrapped in the vehicle?

IF SOMEONE HAD EMERGENCY TRAFFIC , THEY SHOULD NOT SIT AND HOLD IT FOR A NET TO START SOMEWHERE !!! EMERGENCY TRAFFIC SHOULD BE PASSED IMMEDIATELY......

it's an EMERGENCY!!!!!!

SIMPLY STATE IN YOUR PREAMBLES THAT ANYONE THAT HAS EMERGENCY TRAFFIC SHOULD USE PROPER PROCEDURE AND BREAK INTO THE NET AT ANY TIME... .. dont ask for EMERGENCY TRAFFIC!

Seventy threes, seventy thirds, eighty eights....

BELIEVE IT OR NOT , THESE TERMS DO NOT EXIST on voice !

A little history here; CW operators in the early , early days of radio came up with the number code of 7 3 for "best regards" because of the fame of the 73 Winchester rifle. The 73 winchester was the best rifle of the time and the CW guys just took it as "seven three " SEPERATE NUMBERS WHICH IS A 7 and a 3 in CW
--... ...-- Anyone experienced in CW who listens on FM repeaters are likely to tell the operators on there saying seventy three's; that they may as well be using French to sign with, which leads me to the next one that really gripes repeater owners and control operators who have experience on HF.....


Q- signals.....

THEY HAVE NO PLACE ON FM PHONE ON A REPEATER, AND AS FAR AS THAT GOES , THEY HAVE NO PLACE ON FM AT ALL!!

Again, they are created for and from CW and ssb traffic nets ; Q signals were developed for ease of operation on CW and ssb traffic nets.
If you ever do CW , you will find that sending QTH for " my location " is much shorter.

Speaking in voice, especially on FM using Q signals, would make me ask,"WHY DO YOU HAVE TO USE "Q" SIGNALS ??? Because it sounds "cool" ?

Why would you say, "What is your QTH, you have a lot of QRN, QUA Jim lately? QSL?"All the tech licensees are sitting there saying " what the heck is he talking about?"
Or why would you say " Hi , Hi " on voice ( CW .... .. .... .. = H I H I for humor intended) ???
Oh , by the way, coded transmissions ARE NOT ALLOWED ON VOICE per Part 97... hmmm!

Here is "q t h " in CW compared to "my location";
--.- - .... compared to -- -.-- .-.. --- -.-. .- - .. --- -.
here is 7 3 compared to best regards;
--... ...-- compared to - ... . ... - .-. . --. .- .-. -.. ...

That should explain it! Even if you dont know CW, you can see the difference in how many dots and dashes are used in each term !
Many control operators dont say anything at all about users because there are not that many users anymore and they are afraid they will ' run somone off ' .
Did they ever think that maybe that is the reason there are not that many people on repeaters, due to listening to all the LID's using CW lingo on voice ?
It is better to have a few "good operators' than 70 bad ones like on some repeaters in the larger cities.
There are courteous ways to mention these things to newer operators "on the air". Here is one of them, " Hey, you dont have to say all that Q stuff because you are on FM phone, just use it just like you're on a telephone, (remember kids are listening)..... PLAIN ENGLISH! All you are required to do is be courteous and say your callsign every ten minutes as the repeater ID's, and use it when you sign off.... and dont say seventy threes or seventy thirds...... simply say your call and bye, see ya later, etc...." Again PLAIN ENGLISH!
Another one heard on most repeaters " Man, what did you do, you are loud on me , looks like you are putting a 9 ' on me!"
NO.... Both stations through the repeater are hearing the repeater, not each other directly. THERE IS NO WAY TO TELL A STATION WHAT THEY ARE "PUTTING ON A REPEATER" as far as signal strength.
They may be able to tell the other station that "white noise", ( static), is heard on their signal or that they are "picket fencing", ( clipping in and out) , but without being at the repeater receiver with an S-meter hooked to the repeater receiver you cannot tell what signal strength the repeater is receiving.

Listening.... Monitoring.... or calling " CQ" CQ -.-. --.-
Again, when using CW, "CQ" is a lot shorter than "calling any station".
ON FM, SIMPLY KEY UP AND SAY YOUR CALLSIGN OR ASK IS ANYONE ON THIS REPEATER. Make sure you don't "double", (talk at the same time), in any circumstances or band!!

HF SSB:

SSB = sideband, LSB/USB
LSB = lower sideband (used on 40m through 160m.)
USB= upper sideband (used on 20m,17m, 15m, 12m, 10m and also on 6m, 2m, and 440 band.)

When making a call, be sure to listen for a few minutes, which is a good rule to use on any frequency or band! Just because you cannot hear anyone for a minute on HF does not mean that someone else is not listening to a reply from a distant station that they can hear and you cannot. This happens all the time.
Someone will tell a friend to move to " so and so frequency" and they go there and just start talking.... well, Ol' Jim in kentucky may be sitting there listening to Ol' John in California giving a parts list out for an amplifier and Ol' Jim may be using a directional antenna pointed west while your antenna is going north and south. You can't hear John and and Jim is listening to John. If you say your call, Jim should politely tell you "standby'. Chances are he will either remember your call or jot it down so he can return your call when he gets the chance.

On FM repeaters though, listen,................ then just "drop in your callsign" ...... Chances are no one will come back , but dont give up. Maybe all the "QSL'ers" will someday learn to send CW and learn they had been using the wrong operating procedures and come back and talk to you like a normal person on the repeater.

Last but not least .....

ZED is NOT listed as a phonetic for the letter "Z". ZULU is the correct phonetic.
This may not matter much to some on FM , but in an emergency on simplex or any HF voice mode, PHONETICS ARE IMPORTANT AND THEY WERE CREATED SO THAT ALL STATIONS WOULD HAVE A STANDARD TO GO BY WHEN PASSING TRAFFIC IN BAD CONDITIONS.
Zed' may be picked out the noise incorrectly as "head" and a broken leg may be transmitted as a "head" injury due to the station misinterpreting ZED' .... Give us a break people! QSL?????? .

Keindahan Minda




Masalah minda adalah hubungan di antara minda dan juga fizikal yang selalunya dilihat sebagai isu utama di dalam filosofi minda walaupun ada juga isu lain menunjukkan keadaan semulajadi minda yang tidak melibatkan fizikal.

Sebagai seorang manusia, kita tidak akan pernah untuk tidak melakukan kesilapan. Tidak ada seseorang manusia pun lahir ke dunia ini terus dapat berlari. Pelajaran dan pembelajaran adalah satu perkara yang berlaku berterusan sejak dari kita lahir sehingga kita tiada lagi di muka bumi ini.

saya akui, ramai di antara kita melakukan kesilapan, sama ada dengan sengaja ataupun tidak. Sejarah dan kita, apakah yang relevan di antara dua perkara ini ?

Sejarah, adalah satu  titik di mana sejak munculnya sesuatu perkara itu, garis masa yang tertulis dari masa yang lepas sehingga masa kini. Sejarah juga menentukan masa depan sesuatu perkara. Jika kita tidak mengetahui sejarah, maka pincanglah masa depan. Agama, bangsa dan juga negara wujud dari sejarah, ada pepatah klasik dari Tibet yang mengatakan, jika kita tidak memulakan sesuatu perkara tidak akan terjadi sesuatu perkara.

Sejarah negara menjadikan sesuatu negara itu kuat dan bermotivasi serta mempunyai sifat dan keinginan yang kuat untuk memajukan negara dan juga rakyatnya sendiri.

Sejarah agama menjadikan seseorang itu beriman dan percaya serta berani untuk memperjuangkan tuntutan agama.

Sejarah salasiah menjadikan seseorang itu berbangga dan juga berani memperjuangkan apa yang telah nenek moyangnya perjuangkan.

Jika kita mempercayai dan meminati sesuatu perkara, kita seharusnya berani dan sanggup memperjuangkannya. Sejarah adalah penting sebagai eset untuk kita komited terhadap apa yang kita percaya dan minati.

Apabila kita tidak mengetahui sejarah atau buta sejarah, masa depan mungkin pincang dan garis masa juga akan berubah secara drastik tanpa harmoni dan relativiti.

Otak, dikawal oleh manusia itu sendiri dan juga nafsu. Jika anda tidak berusaha untuk mengawal otak sendiri percayalah suatu hari nanti anda akan mati kerana nafsu telah menguasai otak.

Sejarah juga membuktikan ramai mereka yang cerdik pandai dilahirkan dikalangan keluarga yang jahil. Jangan tepuk dada tanya selera, sebaliknya kita perlu fikir dan buat apa yang terbaik. Sebagai contoh, jika anda tidak menyukai seseorang, seharusnya anda mengelak dari bertembung. Janganlah memberi pandangan atau persepsi yang tidak baik sebelum anda mengkaji dan berfikir tentang baik dan buruk tindakan yang akan anda lakukan dan ingatlah, majoriti tidak mewakili kebenaran. Kebenaran yang benar harus anda cari dan kaji sendiri.

Kita dilahirkan dengan pelbagai latar belakang, agama, tahap pemikiran dan juga keadaan sekeliling. Perbincangan adalah jalan terbaik untuk mencari satu keputusan yang dapat diterimapakai. Mitos dan juga khabar angin perlulah dikaji terlebih dahulu.

Sejarah tidak memberikan kemajuan, sebaliknya sejarah adalah faktor kemajuan. Tanpa sejarah, kita fikir kita berada di tahap yang selesa, dengan mengetahui sejarah kita akan cuba untuk menambahbaik keadaan sekarang dan seterusnya mengatur langkah untuk masa depan.

Hidup ini tidak lari dari undang-undang dan juga garis panduan. Undang-undang menjadikan seseorang itu berdisiplin serta komited terhadap apa yang diceburi. Garis panduan adalah untuk menjadikan kita berfikir sebelum bertindak.

Ingatlah, sebarang wacana yang dicanangkan tidak semestinya benar, kepada mereka yang tidak tahu akan sejarah sesuatu perkara dengan mudahnya dapat dipengaruhi oleh mereka yang berniat tidak baik. Generasi muda seharusnya tidak mudah melatah kerana rata-rata diantara kita mempunyai taraf pendidikan yang cukup untuk mematangkan pemikiran kita.

 Kepercayaan dan kebijaksanaan menjadikan kita unik. Keunikan kita sepatutnya digaul dengan keunikan orang lain demi kemajuan bersama. Kepuasan semua tidak mungkin dapat kita penuhi sekurang-kurangnya kita tidak melakukan perkara yang mencemuhkan mereka.

Hidup ini umpama piramid, jika kita masih lagi berusaha untuk memenuhi keperluan asas, kita tidak mungkin melebihkan kehendak. keperluan dan kehendak adalah berbeza bagi manusia normal. Hidup ini seumpama pertandingan dan ingatlah, "In competition individual ambition serves the common good". Pertandingan adalah sekelompok (group) manusia yang cuba untuk menunjukan siapa yang bagus di antara mereka dan "best result comes from everyone in the group doing what's best for himself and for the group."

 "The Only Thing Greater Than the Power of the Mind Is the Courage of the Heart"




IEEE 802.22 Akan Menggunakan frekuensi TV VHF dan UHF

The IEEE has recently released the new 802.22 standard for Wireless Regional Area Network (WRAN) using white spaces in the TV frequency spectrum.

The IEEE 802.22 standard is designed to provide Rural Broadband Wireless Access using Cognitive Radio Technology.
It uses VHF and UHF TV channels between 54 and 862 MHz and is claimed to have a theoretical range of up to 33 km (20 miles). It is envisaged that subscribers would use directional antennas on the roof.

IEEE 802.22 can deliver a data rate of up to 19 Mbps in a 6 MHz wide USA TV channel. Channel Bonding, using more than one channel for Tx / Rx, can provide greater bandwidth. A single channel might be able to support 12 simultaneous users in the coverage area.

Prosecution for illegal radio jamming

In ZL a man has been sentenced for supplying illegal radio jamming transmitters after a combined effort between government agencies.
The man admitted supplying radio jammers and transmitting outside the terms of his radio licence and was fined $2000 in Porirua District Court last month.
This is a good example of government agencies working together to reduce crime in the community, says Radio Spectrum Management National Compliance Manager, Chris Brennan.
Radio jammers are increasingly being used as part of criminal activity. Our team of inspectors works hard to stop criminals getting access to this type of equipment.
New Zealand's Ministry of Economic Development laid charges under the Radio Communications Act after Police found the transmitters during a house search for drugs.

do you need to show apparatus assignment to buy a transceiver here in Malaysia ?
adakah kita perlu untuk menunjukkan penguntukan radas semasa membeli radio di Malaysia ?

Bad Attitude



This is very bad attitude, im not sure either this QRM made from amateur radio operator station itself or not. Please share this video with your friends and family. When i'm (Kuala Lumpur) enjoying my conversation with 9M2AR (Alor Star) about computer and mobile programming on 7043Khz, suddenly somebody rebroadcast VHF repeater's audio to 7.043Mhz and i heard class B amateur radio audio. I'm sure that stations didnt know that their audio being broadcast to 40m. i dont know what is the purpose, but i know this is illegal. At the time i wrote this post, 9W or class B amateur radio do not have privileges to work on 40m.

This video was recorded by my friend from Terengganu.

Saya dengan cikgu Rahman sedang menggunakan frekuensi 7043Khz pada masa itu dan kami berbincang tentang komputer dan mobile programming, tiba-tiba terdengar audio masuk. dikenalpasti bahawa audio itu adalah dari radio amatur kelas B. adakah repeater VHF bocor dan masuk ke 40m ? ataupun berlaku fenomena alam yang luar biasa menyebabkan isyarat VHF masuk ke frekuensi HF ataupun ada seseorang yang berniat tidak baik dengan mengulangpancarkan isyarat VHF masuk ke HF ? bertujuan mengacau dan memporakperandakan keadaan ?. Saya beranggapan bahawa pemilik-pemilik callsign itu tidak mengetahui bahawa audio mereka masuk ke HF. Pada masa saya menulis post ini class B tidak ada penguntukan untuk bekerja di 40m.

Video ini telah direkod oleh rakan saya dari Terengganu yang juga mendengar pada masa itu.

You can do all stuffs you want, because we are living in boleh land, serba boleh!
Anda boleh buat apa anda suka kerana kita tinggal di negara yang serba boleh!

Tapsure - Morse Code Passwords

Tapsure

Typing passwords on mobile devices sucks. If you have even a reasonably strong password (one that includes letters, numbers, and special characters), it can take more than a few seconds to type it out on a phone's keypad or on-screen keyboard. In this day and age, that's time you just don't have!

Tapsure is an extension for Firefox for Mobile that alleviates this problem by allowing you to input passwords on websites by tapping a rhythm on your touchscreen rather than hunting through the device's keyboard.

How does it work?

Install Tapsure here, and after restarting Firefox for Mobile, log into one of your online accounts as usual. After you log in, you'll see a notification from Tapsure:



Choose "Yes," and you'll see this dialog:




(If you choose "No," Tapsure will never ask about that specific password again. If you just close the notification, Tapsure will ask the next time you use the password.)

Here comes the fun part: think of a song, a pattern, a rhythm, or even some Morse code that you want to use to log in to sites that use this password - it can be anything, as long as it doesn't have more than a full second between taps. Got it? Ok, now tap that song/pattern/rhythm/Morse code on the screen. Tapsure will save it and close the dialog.

Now, the next time you're logging into a site that uses that password, instead of slowly typing out your super-secure 20-character password, just hold your finger down on the password field until you see this:




Now tap out your pattern from the previous step, and Tapsure will automatically fill in your password for you. (If you tap the pattern incorrectly, Tapsure will shake it off and give you another chance.)

You can repeat these steps for as many passwords as you like - Tapsure will remember them all.
Tapsure Settings

In the add-on options panel, you can reset all of the patterns you've saved with Tapsure to start over. (This will also clear the list of passwords that Tapsure won't ask you to save a pattern for.)





Is this secure?

Yes, Tapsure saves your patterns and passwords using Firefox's built-in password manager, so it just as secure as having Firefox remember your passwords. Tapsure also has the benefit that someone could closely watch you log in to a website without knowing your password, because it's harder to discern and remember a tapped pattern than it is to watch the keys that you press.
Couldn't I just tell Firefox to remember the password?

You could... but if you use the same password on more than one site (which I estimate that 99.9% of people do), you'd have to type it out with excruciating care on every single site that you use it on.
Miscellaneous

Try and use a semi-unique pattern - don't choose Happy Birthday. It's like using the password "password."

Tapsure probably works better on capacitive touchscreens than resistive touch screens, simply due to the fact that it's easier to tap a quick pattern when you don't have to press down firmly on each tap.

Tapsure was entered in the Firefox Mobile Add-ons Cup. If you want to see it win, please write to your senators and representatives.

Where can I install it again?

Install Tapsure from Mozilla Add-ons

Or, you can search for "Tapsure" in the "Get Add-ons" portion of Firefox for Mobile.

Between Morse Code And Old Fashion Text Messaging

Look at this video, http://www.youtube.com/watch?v=em5DXayPdQ4

Yes, CW wins. 



But, this is not my point. If the phone are using latest technology of typing such as QWERTY keyboard, auto text completion or swiping on touch screen phones, im sure CW is not the winner.



Lets talk about the advantages of CW or Morse code, CW uses only 1/10 spectrum. If you could see CW signals in waterfall display, you will know what i mean. This is what i am talking about. unlike voice operation or phone, CW signals is very narrow. Means that CW can be heard thousand miles away from the transmitter location. No matter what type of band condition you are having, QSB, bad propagation, etc. CW or OOK (on-off keying) is the easiest setup for narrow bandwidth signal, unlike PSK, RTTY. You dont even need any computer to send or receive the signal, just you and yourself transmitting and listening to the code.



CW suitable for emergency communication where you need to send the message in a straight forward plain text. Not like phone operation, where phone operation sometimes lead to a nonsense talk.

Fastest QWERTY keyboard or swiping on touch screen phones can't lead you to a rescuer when you are in bad situation where you phone is useless because the cellular tower or base station are down.

Fastest QWERTY keyboard or swiping on touch screen phones also can be useless if your credit on your prepaid phone line is $0.00.

Amateur Radio Net

An amateur radio net, or simply ham net, is an “on-the-air” gathering of amateur radio operators. Most nets convene on a regular schedule and specific frequency, and are organized for a particular purpose, such as relaying messages, discussing a common topic of interest, in severe weather (for example, during a Skywarn activation), emergencies, or simply as a regular gathering of friends for conversation.

Net operation

Nets operate more or less formally depending on their purpose and organization. Groups of nets may organize and operate in collaboration for a common purpose, such as to pass along emergency messages in time of disaster. One such system of nets is the National Traffic System (NTS), organized and operated by members of the American Radio Relay League (ARRL) to handle routine and emergency messages on a nationwide and local basis.

Formal operation

A formal, or directed net has a single net control station (NCS) that manages its operation for a given session. The NCS operator calls the net to order at its designated start time, periodically calls for participants to join, listens for them to answer (or check in ) keeps track of the roster of stations for that particular net session, and generally orchestrates the operation of the net.

A different station might be designated NCS for each net session. Overall operation and scheduling of NCS assignments and net sessions is managed by the net manager .

When a net covers a large geographic area, such as a continent or even the world, it becomes impractical for a single NCS to control. To cover a large scale area a net must operate on a frequency where signals can propagate long distances. Ironically, the same ability for long distance propagation leads to a situation where stations that are too close in proximity can not hear each other. In this case two or more NCSs spaced geographically from one another can effectively collaborate to maintain contact with all possible participants.

Informal operation

An informal net may also have a net control station, but lack some or all of the formalities and protocols other than those used in non-net on-the-air operation. Or, it could begin at the designated time and frequency in an ad hoc fashion by whoever arrives first. Club nets, such as ones for discussing equipment or other topics, use a NCS simply to control the order in which participants transmit their comments to the group in round-robin style.


Types of nets

Traffic

Traffic nets operate primarily to relay written messages. For decades, amateur radio operators passed both routine and emergency messages on behalf of others as part of its public-service mission.

Today, with inexpensive communication capability available to anyone, routine message handling has dwindled and is largely used for training purposes. During emergencies (such as natural disasters) – especially when normal communications channels are disabled or compromised – traffic nets (utilizing emergency-powered stations) are used to pass information into and out of affected areas.

DX

DX nets are organized to help amateur radio operators make contact with stations in distant locations or regions where amateur radio operators are scarce. By checking into a DX net, a ham could have a chance to contact another station he or she might otherwise not be likely to hear by randomly tuning across the amateur bands.

Club or Topic

Amateur radio clubs often organize nets to foster communication between members on a regular basis. These can be clubs based on geographic location or clubs formed around a special interest.

Special interest clubs or non-club groups often organize nets to enable discussions on a particular topic. A wide variety of such nets are in operation. One such example is nets that meet to discuss vintage or antique radio equipment. Another example is nets for using and discussing the AM mode of voice transmission.

CLUB CALLSIGN -1993 CALLBOOK

The following callsign was taken from MARTS CALLBOOK 1988 & 1993
most of the callsign have been expired/ not renew or the station no more

Amateur Radio Directed net

A net or directed net, in radio-amateur operating procedure, is an organised meeting of multiple stations on a common frequency at a scheduled time. One station is designated to serve as net control; all requests to deliver message traffic to the net are initiated by sending an identifier or callsign to the control station and waiting for that station to reply before continuing.

The directed net structure reduces the number of message collisions, where multiple stations attempting to transmit simultaneously could otherwise cause unwanted interference to communication within the group.

Directed nets are commonly used for scheduled on-air meetings of individual radio-amateur groups. They are also activated to co-ordinate disaster and emergency communication between volunteers during local events and to co-ordinate data collection and weather spotting activity during a regional storm watch or warning.

A scheduled net will often use a pre-defined script which identifies the purpose of the net, invites stations to "check in", allocates time for individual stations to send their traffic sequentially, delivers any announcements and then ends the directed net once all traffic is completed.

This script, as an example, is based on a weekly on-air meeting of a local radio-amateur group. While elements of the basic structure are similar between different nets, individual organisations can and do adapt the general structure to suit their needs.

This is (name)_________ , (call sign)___________, Net Control Operator for the ______ Net.
This net meets at (time)_________ on (frequency)_____________ for the purpose of __________________.

This net is open to anyone interested in (purpose)_____________ in (region served)______________.

If at any time during the Net, should an emergency arise, please notify Net Control. We will stand
by and allow those in need access to this frequency.

Is there any priority or emergency traffic at this time?

This enquiry is **fingers always crossed** greeted with utter silence. So far, so good. Having received no emergency traffic, the net control operator is then free to ask for stations which have routine traffic to identify themselves.

Are there any portable or mobile stations wishing to check in at this time?

Are there any homebase/fixed stations wishing to check in at this time?

Individual stations seeking to address the net send their callsigns, usually in groups of no more than two or three. The net co-ordinator acknowledges each station by callsign, then invites the first station to send its traffic. Once all identified stations in turn have sent any messages, the control operator will ask for the next series of check-in requests.

If traffic is received from a station which is not audible to everyone on the net, but which is receivable at the net control station, the net co-ordinator may repeat the message manually or ask to verify that the intended recipient station copied the traffic. This is not commonly an issue on nets conducted using a local VHF/UHF repeater, but will arise on HF or other simplex nets.

Once all stations in a group (such as mobiles) have finished, the next group is invited to check in to the net. Once all stations wishing to send traffic have done so, time may be allocated for announcements or other specific items before ending the directed net.

Do we have any stations with announcements, bulletins, or news of general interest to the net?

Last call for any stations wishing to check-in to the __________ net,
or any further comments or questions.

There being no further check-ins or comments, this is (call sign)__________
closing the _________ Net, Thanks to all for participating.

This frequency is now returned to regular amateur use. 73 to all.

Stations deployed to provide communication service during public events, or as part of emergency communications operation, will often bear an additional identifier meaningful within the individual net. While these do not fully replace the station's globally-unique government-issued callsigns, they are employed to address traffic within an net based on the rôle a station at a specific location plays in the larger operation. Each deployed ARES or emergency service net at an event will typically contain one control, various fixed stations designated by place name (a town or location) and/or individual mobile units labelled by purpose (admin-one, repair 2...) depending on the incident and the needed response.

While there is normally only one control node on-frequency in the same net at any time, procedure should provide for another station to seamlessly take over the control-one identity and position if the existing control-one station loses backup power or has to abruptly leave the air for any reason. The use of tactical calls ensures that inbound enquiries to the net can continue to be addressed to control without regard for which individual licensed station on the net is currently occupying the rôle.
