Syllabus and details of Amateur Station Operator's Certificate (ASOC)
Examination for the award of Amateur Station Operator's Licence
Ham radio is one of the few hobbies in the world, which requires a government licence. To obtain the licence, one has to go through a course as per the syllabus devised by the communication
authority to be equipped with an optimum amount of knowledge and proficiency which is necessary to communicate using a wireless transceiver without causing interference to the other radio communication services and as
per agreements set up at the international communication meetings. The course covers basic electronic radio theories as well as the existing national and international rules related to amateur radio communication in
radiotelephony (voice) and radio telegraphy (Morse Code).The person who wants to become a ham should at the same time be able to show his proficiency in Morse Code sending and receiving. The Amateur Radio Operator's
Certificate is awarded by the Wireless Planning and Coordination (WPC) Wing of the Ministry of Communication, New Delhi. The examination is conducted at the Wireless Monitoring Stations located throughout the country.
The examination is held for four different categories of licence. They are the :
Advanced Grade Licence
Grade I Licence
Grade II Licence
Restricted Grade Licence.
Anyone above 12 years of age can obtain Amateur Radio Station Operator’s Licence after passing the examination/s mentioned above. It is also possible to establish an Amateur Radio
Club Station with a licenced ham in charge of it.
The application form for Amateur Radio Station Operator's Certificate Examination can be obtained from :
