Format Lines 6, 7, 8, and 9

In the following paragraphs, we will discuss the format lines used in the R/T message format. Refer to table 2-4. FORMAT LINES 1, 2, 3, AND 4 Format line 1 is not used in R/T procedures. Format lines 2 and 3 contain the call sign, the proword MESSAGE, and the transmission identification. The call may take one of the following forms: Full Call “Kamehameha (station called), THIS IS Vallejo” (station calling) Abbreviated Call “THIS IS Vallejo” (station calling). Normally, a full call is used when first establishing a net and when reporting into a previously established net. A full call is also used in the transmission instructions and address components when a message is required to be relayed to a station on a different net. Once communications are established and no confusion will result, an abbreviated call may be used. To further expedite voice communications, the receiving station may omit the proword THIS IS when the station is responding to a call and communications are good. Additionally, the call may be omitted entirely when two stations are in continuous communication or the net is not shared by a third station. When a collective call sign is used and some of the addressees are to be exempted, you do so in the call by using the proword EXEMPT, followed by the call sign(s) of the station(s) exempted. For example: “Edison (collective call) EXEMPT Tecumseh (station exempted), THIS IS Vallejo” (station calling). Notice that only one station is exempted in this call- up. If there had been more than one station, each station would have been spoken before the proword THIS IS. After the call, transmit the proword MESSAGE if you wish to indicate that a message you are about to transmit requires recording. For example: “Vallejo (station called), THIS IS Kamehameha (station calling) MESSAGE” (message is to follow). The transmission identification is normally a station serial number used mostly in teleprinter procedures. When used in voice communications, the transmission identification is the last element of format lines 2 and 3, consisting of the station serial number preceded by the proword NUMBER. Format line 4 contains the transmission instructions, which may consist of the prowords RELAY TO, WORDS TWICE, DO NOT ANSWER, or READ BACK. The use of these prowords is explained later. FORMAT LINE 5 Format line 5 contains the precedence, DTG, and any necessary message instructions. The precedence is the first element of format line 5. In the case of a dual- precedence message, the higher precedence is transmitted first; for example, “PRIORITY ROUTINE.” The DTG is preceded by the proword TIME. An example of this format line is as follows: “Vallejo, THIS IS Polk, RELAY TO Key, PRIORITY, TIME, Tree Zero Wun Fower Fower Fife Zulu.” Message instructions are not normally required in R/T messages. When included, they consist of short and concise instructions that indicate the status of the message. Message instructions remain with the message until the message reaches its destined station. For example, if the message is a suspected duplicate, the phrase “This Message Is A Suspected Duplicate” immediately follows the DTG. FORMAT LINES 6, 7, 8, AND 9 Format lines 6, 7, 8, and 9 form the address of the message and are recognized by the prowords FROM, TO, INFO, and EXEMPT, respectively. When the originator and the addressee are in direct communication, the call may serve as the address. Table 2-5 is an example of an R/T transmission showing elements of the heading components (format lines 2 through 9). 2-12
