Amateur radio or ham radio is a hobby that is practised by over 16,000 licensed users in India.[1] Licences are granted by the Wireless and Planning and Coordination Wing (WPC), a branch of the Ministry of Communications and Information Technology. In addition, the WPC allocates frequency spectrum in India. The Indian Wireless Telegraphs (Amateur Service) Rules, 1978 lists five licence categories:[2]

To obtain a licence in the first four categories, candidates must pass the Amateur Station Operator's Certificate examination conducted by the WPC. This exam is held monthly in Delhi, Mumbai, Kolkata and Chennai, every two months in Ahmedabad, Nagpur and Hyderabad, and every four months in some smaller cities.[3] The examination consists of two 50-mark written sections: Radio theory and practice, Regulations; and a practical test consisting of a demonstration of Morse code proficiency in sending and receiving.[4] After passing the examination, the candidate must clear a police interview. After clearance, the WPC grants the licence along with the user-chosen call sign. This procedure can take up to one year.[5] This licence is valid for up to five years.[6]

Each licence category has certain privileges allotted to it, including the allotment of frequencies, output power, and the emission modes. This article list the various frequencies allotted to various classes, and the corresponding emission modes and input DC power.

## Selected station

BBC Local Radio is the BBC's regional radio service for England and the Channel Islands, consisting of 40 stations. Initially, stations had to be co-funded by the BBC and local authorities, which only some Labour-controlled areas proved willing to do. Radio Leicester was the first to launch on 8 November 1967, followed by Sheffield, Merseyside and Nottingham. By the early 1970s, the local authority funding requirement was dropped, and stations spread across the country; many city-based stations later expand their remit to cover an entire county. Today, stations are asked to target their coverage to Dave and Sue, two fictional fifty-five-year-olds.
