Note –The above written test is of one-hour duration. The maximum number of marks is 100 and candidate Must secure at least 40% in each section and 50% in aggregate for a pass.
Section 1 : Morse Receiving : (Speed : 5words 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 signals from an audio 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 5 errors will disqualify a candidate.
Section 2 : Morse Sending : (Speed : 5words per minute)
The test piece will consist of a plain language passage of 125 letters, 5 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 5 uncorrected errors will disqualify a candidate. The accuracy of signaling, correct formation of characters and the correctness of spacing shall be taken into account.
Note – A candidate is required to pass both in Part I and Part II. In the case of candidates qualifying in Part I only, the license shall be restricted to radiophone operations only.
Same syllabus as for the Amateur Station Operators Grade II examination. The test is of 2 hours duration. The maximum number of marks is 100 and candidates must secure at least 50% in each section and 55% in aggregate for a pass.
(a) Section 1 : Morse Receiving (Speed 12 words per minute)
The test piece will consist of a plain language passage of 300 characters, which may comprise of letters, figures and punctuations (Punctuations 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 amateur Station Operator’s Grade Ii examination.
Note – Test piece may contain only the following punctuations Full stop; comma; Semi-colon; Break Sign; Hyphen and question mark.
(b) Section 2 : Morse Sending (Speed 12 words per minute)
