To obtain a licence, candidates must pass the Amateur Station Operator's Certificate examination conducted by the WPC.[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 lists the various frequencies allotted to various classes, and the corresponding emission modes and input DC power.
