The written examination for Grade II licence is of one hours duration. The maximum number of marks is 100. Candidates must secure at least 40 per cent in each section and 50 per cent in aggregate to pass.

The syllabus for Grade I licence is the same as that for Grade II licence, but the written examination for Grade I licence is of two hours duration. The maximum number of marks is 100 and candidates must secure at least 50 per cent in each section and 55 per cent in aggregate for a pass.

Part II : MORSE CODE

(a) Section I : Morse receiving (Speed: 5 words per minute)

The test piece will consist of a plain language passage of 125 letters, five letters counting as one word. Candidates are required to receive for five consecutive minutes at the speed of 5 words per minute from a double headgear headphone receiver, international Morse code signals from an audio frequency oscillator keyed either manually or automatically. A short practice piece may be sent at the prescribed speed before the start of the actual test. Candidates will not be allowed more than one attempt in each test. The test may be written in ink or pencil but must be legible. Bad handwriting and over-writing will render a candidate liable to disqualification.

 More than five errors will disqualify a candidate.

 (b) Section II : Morse Sending (Speed: 5 words per minute)

The test piece will consist of a plain language passage of 125 letters, five letters counting as one word. Candidates are required to send on an ordinary key for five consecutive minutes at the minimum speed of five words per minute. A short practice piece may be allowed before the actual test. Candidates will not be allowed more than one attempt in the test. Efforts should be made to correct all errors. However, more than five uncorrected errors will disqualify a candidate. The accuracy of signaling, correct formation of characters and the correctness of spacing shall be taken into account. A candidate is required to pass both in Part I and Part II. In the case of candidates qualifying in Part I only, the licence shall be restricted to radiotelephone operations in the VHF ham band only.  characteristics-sensitivity, selectivity, fidelity; adjacent channel and image interference; AVC and squelch circuits; signal to noise ratio.

Transmitter

Morse Code test for Grade I

Receiving-(Speed: 12 words per minute)

The test piece will consist of a plain language passage of 300 characters which may comprise letters, figures and punctuation (punctuation are indicated below). The average words shall contain five characters and each figure and punctuation will be counted as two characters. Candidates are required to receive for five consecutive minutes at a speed of 12 words per minute. Other conditions are the same as applicable to Grade II Examination.
