Amateur radio or ham radio is practised by more than 16,000 licensed users in India. The first amateur radio operator was licensed in 1921, and by the mid-1930s, there were around 20 amateur radio operators in India. Amateur radio operators have played an important part in the Indian independence movement with the establishment of pro-independence radio stations in the 1940s, which were illegal. The Wireless and Planning and Coordination Wing (WPC)—a division of the Ministry of Communications and Information Technology—regulates amateur radio in India. The WPC assigns call signs, issues amateur radio licences, conducts exams, allots frequency spectrum, and monitors the radio waves.

The International Telecommunication Union has assigned India the following callsigns:
Callsign | CQ | ITU |
---|---|---|
8TA to 8YZ | 22 | 41 |
VU to VW | 22 | 41 |
ATA to AWZ | 22 | 41 |
Note: The Andaman and Nicobar Islands come under ITU Zone 49 and CQ Zone 26.
In addition to the above, the base of Maitri and the abandoned station of Dakshin Gangotri, also use the Indian callsigns but come under ITU Zone 67 and CQ Zone 38 respectively.[1][2]
The International Telecommunication Union (ITU) has divided all countries into three regions; India is located in ITU Region 3. These regions are further divided into two competing zones, the ITU and the CQ. Mainland India and the Lakshadweep Islands come under ITU Zone 41 and CQ Zone 22, and the Andaman and Nicobar Islands under ITU Zone 49 and CQ Zone 26. The ITU has assigned to India call-sign blocks 8TA to 8YZ, VUA to VWZ, and ATA to AWZ.[3][4] The WPC allots the individual call-signs, or call sign series.
