STEPS INVOLVED IN BECOMING A HAM RADIO OPERATOR |
There is a general misconception that a person can call herself/himself a ham radio operator if she/he becomes a member of a ham radio club/society. There are of course ham radio clubs and amateur radio societies, which help newcomers by providing guidance to become a ham radio operator. The club station maintained by Vigyan Prasar is VU2NCT.
Why be a ham?
There are many reasons for a person to become a ham radio operator. Some become ham for sheer adventure; some want to build their own equipment; some just want to make friendship by leisurely talking with fellow hams from around that world; some for the sheer belief that if they become ham then they would be able to talk to their family when they go far apart at a very low cost. To some, ham radio is just a simple hobby for the pastime when they have nothing to do. For the techno-savvy, it is an excellent way to fulfill their craving for sophistication. Those who are 'civic-minded' get the opportunity to carry out ‘disaster preparedness’ activities by way of operating their wireless sets during 'mock exercises' so that in the event of a distress they can help their fellow beings when all other modes of communication may fail. An industrious ham with a technical bend may take it as an opportunity to research and develop radio equipment for her/his fellow ham radio operators, which may turn out to be a profitable proposition. For the sailors and for the people who have to go to remote places, becoming a ham is an added advantage. While ham radio provides merriment to the hobbyist, to the sailors and explorers it is an utility. They can even send e-mails to their families/friends right away from the sailboats or vehicles without any internet connection and that too without any cost! This becomes possible through a dedicated global network of ham radio stations popularly known as ‘Winlink’ (for more information please refer to: http://www.winlink.org). In fact, with a technology known as PACTOR-III, ham radio operators can virtually send any file formats from one computer to another using radio waves. Ham radio has lots of utility, but it is not a replacement of other modes of communication (Landline Telephone, mobile telephone, Internet/e-mail etc.) so long as government regulation does not permit hams to do so. PDF documents related to the hobby with more information may be downloaded from: http://www.qsl.net/vu2msy/vipnet/
Licencing Examination
A Licencing examination (Amateur Wireless Telegraph Operator's Licencing Examination) is conducted by the Wireless Planning and Co-ordination (WPC) wing of the Ministry of Communications & Information Technology, New Delhi at any one of the 22 Wireless Monitoring Stations located throughout the country. You need to apply to the 'Officer-in-Charge'(OC)/Engineer Inspection of the Wireless Monitoring Station nearest to your hometown (or wherever you wish). The examination consists of a 100 marks question paper (50 marks related to basic radio/electronics theory as per the prescribed syllabus ( http://www.qsl.net/vu2msy/SYLLABUS.htm ) and 50 marks related to Amateur Radio Rules & Regulations: http://www.qsl.net/vu2msy/asocrules.htm) which is of one, two or three hours duration as per the "grade" of licence you intend to appear. There are 4 grades of licences. A practical test on Morse Code sending & receiving (at the speed of 5 WPM & 8 WPM) is also conducted to examine the candidate's proficiency in wireless telegraphy communication ( http://www.qsl.net/vu2msy/MORSE1.htm Morse code learning software can be downloaded from: perso.club-internet.fr/f1orl/cwpeng.htm) You can apply for more than one grades at a time, provided, separate application forms along with the prescribed examination fees, for each grade in the form of Demand Draft issued from a "State Bank of India" branch drawn in favour of the "Pay & Accounts Officer (Headquarters), Department of Telecommunications, New Delhi-110 001, payable at SBI New Delhi Service Branch (Code No. 7687) are sent to the "Officer-in-Charge" of the Wireless Monitoring Station where you will be appearing for the ASOC examination.
Examination Fees:
Advanced Grade: Rs.25/-
Grade I: Rs.20/-
Grade II: Rs.10/-
Grade II (Restricted): Rs.10/-
SWL (Short Wave Listening Licence to listen hams) Licence: No examination (no fees).
The particulars of the "Venue" and "Date" etc. of the examination would be communicated by the Officer-in-Charge of the concerned Wireless Monitoring Station on receipt of completed application form along with the requisite examination fees.
Following should accompany the application form
(To download: Right Click > Save Target As):
(1) Nationality Certificate/ (To download: Right Click > Save Target As)Character Certificate in the prescribed proforma from a gazetted officer.

After the declaration of the result, a copy of the result and your "Personal particulars" would be forwarded by the Wireless Monitoring Station to the WPC Wing of the Ministry of Communications & Information Technology, New Delhi. The WPC Wing, New Delhi would then undertake an interministry consultation ( Security Clearance/Police Verification ). After the police verification report is received with a clearance, the WPC Wing would write to you that you are eligible for the award of an "Amateur Wireless Telegraph Station Licence" on payment of the requisite "Licence Fees'. This process takes a few months of time. 'Examination Fee' and 'Licence fee' are different and the 'Licence fee' should be sent only when asked for. This time, the mode of payment is same as above, but you have to send it directly to:

B. Different grades of licencing examinations & licences:
(1) Grade-II (Restricted) Amateur Station Operator's Licence (if you pass Restricted Grade licensing Examination): Permits short distance terrestrial communication using a power output of 10 Watts (dc input power) in the Very High Frequency (VHF) & Ultra High Frequency (UHF) bands. The frequencies allocated in these bands ranges from 144 to 146 MHz (in India) and 434 to 438 MHz. Modes of communication allowed are: Radio Telephony(Voice) using Amplitude Modulation (AM), Single Side Band (SSB), SSB Suppressed Carrier, SSB reduced carrier and Frequency Modulation (FM). Communication range is limited to a very short distance (a typical possible range may be 35 km only depending on the height of the antenna or the type of terrain). This type of licence is useful in a place where there are large number of ham radio operators concentrated in a township.
(2) Grade II Licence (if you pass Grade-II licensing examination): Permits worldwide long distance communication in AM, SSB, FM using a power output of 50 watts in different allotted short wave bands (high frequency-HF bands ranging from 1.8 to 30 MHz) including the VHF & UHF bands mentioned above. But entitlement for authorization of voice communication (radio telephony) is on the basis of providing proof of having made 100 contacts with other amateur radio stations using Morse Code (Called Continuous Wave-CW communication). This means that you have to send back your original licence to the WPC wing for "Voice endorsement" along with the photocopies of your log book (see Rules & Regulation Section) after making 100 Morse Code radio contact.
(3) Grade-I: (if you pass Grade-I licensing examination): Power output is 150 watts in short waves (in the allotted HF bands), 25 watts in VHF & UHF (Ultra High Frequency). An additional UHF spectrum from 1260 to 1300 MHz including a range of frequencies in Super High Frequency (SHF: 3300-3400 & 5725-5840 MHz) spectrum is available to this category of licensees. With this licence you can directly use voice including Morse Code. Other advanced modes like Radio Tele-Typing (RTTY), Amateur Radio Teleprinting Over Radio (AMTOR), Packet Radio (-an advanced technique of digital data communication through computer connected to a wireless transceiver), PSK31 (the latest digital communication mode in which a computer equipped with a sound-blaster card can be directly connected to a wireless transceiver for data reception and transmission), Amateur Television (ATV using Slow Scan Telecast: SSTV) are also allowed. You are also permitted to work amateur radio communication satellites with this licence.
(4) Advanced Grade: Same as Grade-I licence but allowed to use 400 watts of power in selected sub-bands. This is the highest grade licence in India.Every ham radio enthusiast in India aspires to get it.
Practical Test on MORSE CODE SENDING & RECEIVING
One of the most frequently used "Important" modes of communication in ham radio is "Morse Code". There is a practical test on Morse Code sending and receiving (except for Restricted Grade Licence where this test is not required). This is a 10 minutes duration test to examine the candidate's proficiency in sending and receiving Morse Code. Minimum specified speed to pass the examination is 5 Word Per Minute for Grade-II licence (5 WPM: 125 letters/characters sent in 5 minutes). To learn Morse code, a Morse Code Practice Oscillator can be assembled along with a Morse Key and a Morse Code learning Cassette can be found useful ( http://www.qsl.net/vu2msy/homebrewing_zone.htm ). Morse Keys are only available at some junk markets.

ایزدی - یه مشکلی داره این طرح. کل سلف ها با هم 12. 7 میکرو میشه که با خازن 270 پیکو، فرکانس مرکزی فیلتر 2.7 مگا هرتز می شه. کمترین سلف هم (0.1 میکرو) با همون خازن 270 پیکو 30 مگاهرتز رو رد می کنه. بنا بر این نیازی به خازن های دیگه نیست. دوستان دیگه نظرشون چیه.
پاسخ:باسلام و تشکر کل خازن ها و سلفها برای فرکانس 1800کیلو که ابتدای باند رادیو اماتوری است کم است و بسختی تنظیم می شود اما برای 3500 بله زیاد است - 1399/8/24
هومن - سلام .علت استقبال نکردن در خور توجه همین نا واردیست .این مطلب بسیار گنگ و پر از اشتباه هست
پاسخ: سلام بنده هم ضمن تائید نظر شما درخواست می کنم مطلب کامل تر و بهتر و درست تر را بفرمائید بنده بنام خودتان درج و منتشر نمایم

پاسخ: سلام بهیچ عنوان و تقریبا هیچ جائی من چنین ادعائی نکرده ام اما این همه شهید و زخمی و جانباز و اسیر و زحمت و فعالیت برای حفظ انقلاب و سرزمین عزیزمان ایران خیلی حرام لقه گی و بی اصل و نصبی می خواهد که چشم خودرا ببندیم و از این اب و خاک حمایت و به این مردم عشق نورزیم حالا شما اسم انرا هرچه دوست دارید بگذارید نظرتان محترم است - 1396/12/17
هومن - سلام
بنده یکی از علاقمندان لامپ هستم . و 10 سال اخیر را بر روی مدارات لامپی کار کردم .با سرچ اینجا را پیدا کردم .می خواستم ببینم در زمینه مخابرات فعالیت لامپی در ایران هست ؟
این مطلب راجب لامپ واقعا توجه مخاطب علاقمند را جلب می کند ؟
من فکر می کنم نویسنده اصلا راجب لامپ حس خوبی ندارد .عذر خواهی می کنم
پاسخ:سلام دوست عزیز از صراحت و فصاحت بیان شما خوشحالم مطلبتان راجع به نویسنده مطلب لامپ کمی کم لطفی و شاید سخت گیری در بر دارد نویسنده مطلب استاد عاملی بزرگ رادیو اماتوری ایران هستند و مطلب را بی اندازه ساده و اسان گفتند چون اکثر جوانها از لامپ و ولتاژ کار ان وحشت داشته و تقریبا هیچ نمی دانند اما ظاهرا شما در مورد لامپ مطلع و ازموده هستید لذا برخود نگیرید شما هم اگر در مورد لامپ و یا مطالب استاد عاملی نقد و نظری دارید بسیار خوشحال می شوم مکتوب بفرمایید تا در همان بخش یا در بخش جدید بنام خودتان منتشر شود

سعیدی - سلام استاد بنده بی جواب ماندم
پاسخ:با سلام و پوزش از تاخیر طبق تجربه دوستان این مدار به دلیل نامرغوب بودن قطعات نو موجود در بازار معمولا در ابتدا کار نمی کند لذا بتوصیه استاد عاملی بهنر است از قطعات اوراقی رادیو و ضبط ها استفاده شود قطعات معمولا در گیر این رادیو ابتدا ای سی سویچ یا کلید زنی است که یک مدل خاصش برای مدار مناسب است و مدلهای دیگر فرکانس کار و ولتاژشان مناسب نیست درمورد ای سی مدولاتور و دمدولاتور 3028 این ای سی هم بشدت مورد شک و شبهه است در موردی باتعویض 5 عدد ای سی دو عدد که بهتر بود در مدار بکار گرفته شد لذا بهترین روش استفاده از مرحله مرحله و گام بگام کار کردن رادیو است ضمن انکه اگر فرستنده کار بیفتد گیرنده هم کار خواهد کرد و بالعکس لذا شما می توانید مدار را از میکروفون در حالت فرستنده یا بلندگو در حالت گیرنده شروع نمایید و اگر مسیر سیگنال جدا باشد در نقشه شما می توانید از تقویت صدا شروع کرده و به دمدولاتور رفته و سپس به فیلتر و بعد میکسر وی اف او و در اخر به فیلتر تنظیم باند بروید و حد اکثر سیگنال و حساسیت را بدست اورید پس فیلتر های رادیویی یا بقول شما توکو ها قسمت اخر تنظیم و تعقیب مدارتان است اگر شد برای اطلاع شما و سایر دوستان مدار را در حالت گیرنده و فرستنده جدا اراعه خواهم داد یا با رنگ مسیر سیگنال را جدا می کنم که راحت تر باشد اگر شما عضو تلگرام هستید در یکی از گروه های رادیو اماتوری بیایید و مستقیما با دوستان سازنده و استفاده کننده رادیو تماس گرفته راهنمایی شوید اگر نه ادرس ایمیلتان را بدهید تا راهنمای مونتاژ را برایتان بفرستم
