Punctuation in a radiogram is simple. No punctuation such as commas, periods, colons, hyphens, question marks, etc. are permitted in a radiogram. Instead, other characters or words are used in their place. For example, “X” is used to indicate a period (but should NOT be used as the last group in a radiogram) and the word QUERY is used in place of a question mark. Hyphens or dashes should be left out, unless they are necessary, then should be written as HYPHEN or DASH.
