Introduction
MyfirstintroductiontoaVHFradiowaswhileenjoyingaweeklongsailingvacationaroundtheGreekIonianIslands.Myhusband,Simon,andIjoinedforceswithanothercoupleandhireda33’sailboat.Thefourofusbecamepartofasailingflotilla.Everymorningwewouldbebriefedwithourdestinationfortheday.Thevacationcoordinatorswouldmakesurethatweleftourmooringandthenhelpedustodockuplateronintheafternoon.
Inordertocommunicatewiththecoordinatorsor‘LeadBoatCrew,’whokeptcloseby,wehadtousetheVHFradio.Thankfully,myhusbandandoneofourfriendshandledallthecommunications,asmygirlfriendandIweretooscaredtousetheradio.I’mnotsurewhatcausedmyfearoftheradio–perhapsIdidn’twanttomakeamistake?

VHFRadioGeneralTipsandInformation
LocatedbelowaretipsandinformationonusingtheVHFradio:
- Channel16isthechannelthatyoushouldkeepyourradiotunedtoatalltimes.It’susedforinitiallycallinganotherboatorplace,emergencies,messagesfromtheCoastguardandsafetywarnings.
- Alwayslookattheradiochannelbeforeusingit.Someonecouldhavechangedthechanneltohearaweatherforecastorspeakwithsomeoneandfailedtoturnitbacktochannel16.
- Holdthemicrophoneashortdistanceawayfromyourmouthandmakesureyoudepressthesidebuttontospeakbeforeyoustartspeaking.
- Whenyouspeakallowyourvoicetoprojectforwardandacrossthemicrophoneratherthanspeakingdirectlyintothespeakingarea–yourvoicewilltransmitmoreclearlythisway.

- Don’teverysay‘overandout’!Thatessentiallymeans‘overtoyouandalso,I’mhangingup.’Youcan’tdobothatthesametime.Anyonelisteningtoyourcommunicationwillthinkyou’reagoofball(orworse)!
- WhenyousendoutanautomaticMAYDAY(pushingaMOBbuttonordepressingthedistressbuttonontheradio),doyourbesttofollowitupwithaverbalmessage.BoatsthatreceivetheMAYDAYmessagearerequired,bylaw,toassistanyonethatsendsoutanalerthoweverifyoucanverballyconveyyoursituation,youmightgetaquickerresponse.
- BylawyouneedtoholdalicensetouseaVHFradioORusetheradiounderthesupervisionofalicenseholder.Manyboatersdonotabidebythislaw.

- IfnooneanswersyourVHFbroadcast,therulesstatethatyoumustwaitatleasttwominutesbeforeyoucallagain.Usually,ifyoudon’thearbackfromthepersonyou’recallingaftertwoattempts,you’rebestbetistotryagainlater.
- Whenreadingoutnumeralstheprotocolistospeakthemdigit-by-digit.Forexample,whenspeakingaboutalatitudeandlongitude,you’dsaysomethinglike:Fivezerodegreesonetwodecimalfourminutesnorth,zero,zeroonedegreestwoeightdecimalsixminuteswest.Andwhenreadingtime,12:30wouldbeonetwothreezero.
- Usethephoneticalphabet(A,forAlfa,ispronounced‘AlFah’)whenlistinganyletters.Forexample,mycallsignisMike(M)Charlie(C)Delta(D)Juliet(J)eight.WhenspeakingoveraVHFradioit’softendifficulttohearsothephoneticalphabetreducesthechanceofmishearingaletter.I’veprovidedaphoneticalphabettableattheendofthisguideasareference.
- Usephoneticnumeralpronunciationwhensayingnumbers.Forexample,oneispronounced,‘Wun’andtwoispronounced,‘Too,’andsoon.Again,I’veprovidedatableattheendofthisguide.
