Part Il-Morse Code
 Morse receiving: (Speed: 8 words per minute)
The test piece will consist of a plain language passage of 200 characters which may comprise of letters, figures. Test piece may also contain the following punctuations i.e. full stop; comma; semi colon; break-sign; hyphen and question mark. The average words shall contain five characters and each figure and punctuation will be counted as two characters. The test will be for five consecutive minutes at a speed of 8 words per minute. A short practice piece of one minute shall be sent at the prescribed speed before the start of the actual test. Candidates will not be allowed more than one attempt in Morse reception and sending test; the test may be written in ink or pencil but must be legible. Over-writing will be treated as error. If any correction is required the candidate may struck the wrong character and write the correct above the character. More than 5 errors will disqualify a candidate. However ii a candidate receives without any error in any part of the passage continuously for one minute duration will be declared successful in the Morse reception test.
 Morse Sending (Speed: 8 words per minute)
The test piece will be similar to Morse Receiving test for Amateur Station Operators’ License (General) examination. Candidates are required to send for five consecutive minutes at a speed not less than 8 words per minute. Other conditions are the same as applicable to Amateur Station Operators’ License (General) examination.
 Note- A candidate shall have to pass both receiving and sending simultaneously.
