CGTTP 6-01.1BRadiotelephone Handbook1. IntroductionThis handbook gives general, unclassified radiotelephonetactics, techniques, and procedures (TTP) for U.S. CoastGuard (USCG) use. See reference (b), CommunicationInstructions Radiotelephone Procedures, AlliedCommunications Publication (ACP) 125 (series), fortactical military procedures.Radiotelephone is telecommunication by voice radio. It isone of the most common forms of communication betweenUSCG, federal, state, and local authorities and the maritimepublic.Appendix A: Glossary and Acronyms has a list of commonradiotelephone terms and definitions.The maritime public might not understand strict militaryprocedures, so you might have to use internationalradiotelephone procedures when communicating with nonmilitary vessels or aircraft.Per reference (a), Development System and StandardsTactics, Techniques, and Procedures (TTP), CGTTP 1-01(series), “CGTTP is NOT policy and is not used to replaceor fix policy gaps.”Revision2. Notes,Cautions,WarningsNOTE:The following definitions apply to notes, cautions, andwarnings found in this TTP.An emphasized statement, procedure, or technique.CAUTION:A procedure, technique, or action which, if notfollowed, carries the risk of equipment damage.WARNING:A procedure, technique, or action which, if notfollowed, carries the risk of injury or loss of life.1
CGTTP 6-01.1BRadiotelephone Handbook3. BasicOperatingRulesRadiotelephone users speak for, and with the authority of,their command. Always follow established procedures tomaintain circuit discipline. Sectors and communicationstations monitor radiotelephone circuits to ensurecompliance with professional standards.3.a. ProhibitedPracticesReference (b), Communication Instructions RadiotelephoneProcedures, Allied Communications Publication (ACP) 125(series), prohibits the following radiotelephone practices:3.b. Operatingthe Radiotelephone Set Violating radio silence. Unofficial conversation between operators. Transmitting on a directed net without permission(except for flash or immediate precedence traffic). Excessive tuning or testing for more than 10 seconds. Failure to listen before transmitting. Transmitting the operator’s personal sign or name. Using other than authorized procedure words(prowords). (Appendix B: Authorized ProcedureWords (Prowords) of this handbook is a quickreference guide). Unauthorized use of plain language in place ofapplicable prowords or operating signals (OPSIGs). Any other unauthorized use of plain language. Linkage or compromise of classified call signs andaddress groups by plain language disclosures orassociation with unclassified call signs. Profane language or loss of temper.Make all radiotelephone transmissions as clear and conciseas possible: Refer to standard operating procedures (SOPs) ormanufacturer guidelines. Know the equipment. Be alert. Speak in a confident tone of voice. Release the push-to-talk button after each phrase or2

PhoneticAlphabetEnsure receiver volume is turned up enough to detectweak signals, but not so loud as to damage yourhearing.Use the phonetic alphabet to identify letters, or spell a wordor group of letters. The underlined portion of the spokenword is the emphasized letter or syllable:LetterAPhoneticALFASpoken RASEE-AIR-RAHTTANGOTANG-GOUUNIFORMYOU-NEE-FORM CKS-RAYYYANKEEYANG-KEYZZULUZOO-LOO3

SpellingDo not use the proword FIGURES when transmitting message headings.Use the phonetic alphabet to spell out difficult words (orgroups) within the message text, preceded by the prowordI SPELL. If the word in question can be pronounced, do sobefore and after spelling it.4

CGTTP 6-01.1BRadiotelephone Handbook3.h.AbbreviationsUse abbreviations when radio conditions are satisfactoryand the abbreviations are sufficiently well known to avoidany confusion.Speak common abbreviations as in normal speech (e.g.,speak ETA as “ETA,” speak NATO as “NATO”).In difficult radio conditions, it might be best to spell theabbreviations phonetically to ensure they are understood onthe first transmission (e.g., speak ETA as I SPELL ECK-OH TANG-GO AL-FAH).Notable exceptions to abbreviation use are uncommonabbreviations, initials used alone, or initials used inconjunction with short titles. In these cases, use thephonetic alphabet preceded by the proword I SPELL (e.g.,ACP 125 is spoken as I SPELL - AL-FAH CHAR-LEEPAH-PAH FIGURES WUN TOO FIFE).3.i. DatesSpeak dates digit-by-digit using the month’s full name:20 AUG3.j. InitialsSpoken as: FIGURES TOO ZE-ROHAUGUSTUse the phonetic alphabet for personal initials, preceded bythe word INITIALS:Example: W.E. Lewis is spoken as INITIALS WISS-KEY ECK-OH LEWIS3.k. RomanNumeralsPrecede roman numerals by the phrase ROMANNUMERALS, then transmit as the corresponding Arabicnumerals.3.l. PunctuationDo not use punctuation unless necessary for messageclarity. Punctuation can be repetitive, consume valuabletime, and increase the chance for errors. When usingpunctuation, speak it as stated below.6
