When one single word in a plain language text is garbled, request repetition using the prosign WB or WA using the shortest word as reference point.
When two or more consecutive words are garbled in the text, request repetition from the correct word before the garbled portion to the first correct word after the last part of the garbled portion.
When one single group in a coded text message is garbled, request repetition using the numerical number which identifies that particular group. When three or more consecutive groups in a coded text message are garbled, request repetition from the first garbled group to the last garbled group.
When the ending of a message is garbled, request repetition of everything after the last word or coded group in the text. There are five portions of a message in which the receiving operator will normally interrogate.
Use the prosign INT followed by the item to be questioned. Interrogate on the basis of what you believe to be correct. Interrogating the group count of a coded text message, the following separate steps must be taken if the group count is questioned incorrectly. Use sample message:. Group count was questioned incorrectly. The automatic transmission reply discloses the correct groups are six GR6 and requests the receiving operator to check each group received with the six letter in the automatic transmission to see which group was missed in receiving coded message.
Finding out what group was missed, the receiving operator must request a repetition IMI for that group before receipting for message.
See Figure Prosigns are one or more letters, characters, or combination thereof, used to facilitate communications by conveying, in a condensed standard form, certain frequently used orders, instructions, requests, and information relating to communications. The following is a complete list of prosigns authorized for military use on radiotelegraph circuits. An overscore a line over two or more letters means the overscored letters are transmitted as a single character; that is, without a pause between letters.
Operating signals are three-letter signals used to expedite communications. They start with the letter Q or the letter Z and convey frequently used orders, requests, and information relating to communications. When giving an answer, advice, or order, an operating signal may convey a different meaning by changing the suffix using QSA ; for example, the strength of your signal is The operating signal Z GE2 will be used for this purpose.
All format lines do not necessarily appear in every message, however, when used, they will be in the order shown. NOTE: When a word appears more than once, that word used as an identity applies to the first appearance. Reference to subsequent appearance of the word must be further identified by means of adjacent words. After receipt for a message has been obtained, all requests for repetition must be in the form of a new message. Request for acknowledgement is initiated by originator addressee.
C2S receiving permission from the addressee to acknowledge the message transmits:. Section IV. NRI Calls a. Calls originating from a telephone subscriber. I have your call completed. Your call sign is W6T You will be speaking to W6T Use strict radiotelephone procedure at all times. Do you have any questions? Standby please. Section V. Spark jamming. Simplest and most easily produced of all jamming signals. To the operator, it sounds like a loud burst of noise of short duration and high intensity, usually repeated at a rapid rate.
Because of the rapid repetition and time required for the receiver, earphones, and human ear to recover from the loud burst of noise, the spark jamming signal is very efficient. Random noise jamming.
Most effective and dangerous type of communications jamming, because the operator may mistake it for receiver or atmospheric noise and fail to report it.
Chapters 1 and 2 are concerned with basic law provisions of laws, treaties, and regulations with which every operator should be familiar and basic operating practice radio operating procedures and practices generally followed or required in communicating by means of radiotelephone stations. The remaining chapters and the sample test, which is appended, are devoted to basic broadcasting basic regulatory matters applicable to the operation of AM, commercial FM, and noncommercial educational FM broadcast stations.
