Theseareanotherexcellentsetofradiosthathavemanyfinefeaturesforscanningandtrunking.However,anyonewhohastriedtoreadthemanualsthatcomewiththeradiosknowitcanbea
littlehard(ifyou'relucky)tofind,read,andfigureoutsomeofthesteps,especiallyinthesearchingandtrunkingsections.IMHOtheyareamess.

Ican’tremembereverythingandfindmyselfreferringbacktothemanualforexplanationsofproceduresandfinditfrustratingtryingtofigureoutthewordingeverytime.Idecidedtowriteand
publishthisformyselftomakeiteasiertousetheradioandamhappytoshareitwithyou.Thisshouldalsomakeiteasierformostpeopletousesomeofthemoreadvancedfeaturesoftheradio
(andgettheirmoney’sworthifyoupaidfullpricefortheradionew)asIwilltrytoexplainproceduresalittlemoreclearlyandinamorelogicalorder.Granted,theseradiosaren'tsimplesoyou
willhavetospendsometimeonthembutthismanualwillatleastmakeiteasier.Ifyoufollowtheredhighlightedtextintheprogrammingsections,youshouldfindwhatyouneedtoknow.Ifyou
wanttofindoutwhat'sreallygoingonwiththeradio,readeverythingelse.

Someofthebetterfeaturesoftheseradiosaretheabilitytoreceivetonecodesincertainservicesearches,theseekfeatureinsearchmodethatresumessearchingafter5seconds,andthe
adjustableIDdelay.IDscanbelockedoutinopenmode(vs.theolderPro93/2053/94/95).TheSkywarnletsyouprogram3Skywarnfrequencies(oranyotherconventionalfreqs)intochannels
997999foronetouchaccesstothem.TheRepeaterFinderToolwillhelpyoufindthecorrectLCNforLTRsystems.Thebestone,inmyopinion,istheabilitytoconfigureeverythinginthe
software,onthecomputer,andthenjustshootittotheradio(withaonewaycable)orbacktothecomputer(withatwowaycable).Mucheasiertoworkwiththekeyboardandseethemonitor.
Youcansettheattenuatorgloballyorperchannel.Withacoupleofkeystrokes,youcanviewtheIDsastextorcode.Thereare5IDlists(30IDsperlist)tostore150IDsforeachbank.

Now,ontheflipside,therearesomeprettyannoyingthingsabouttheseradiostoo.TheystillhavepresetstepsthatwillnottunetomanyofthesplinterfrequenciesintheVHFrange(exceptthe
108137airband)like151.0125;(itacceptsitas151.01).TheAirservicesearchisrelativelyslowbecauseofthe8.33kHzsteps.Stillonly1prioritychannel?Thebacklightgoesoutlongbefore
thebatteriesdie.
AnoverviewofthefeaturescanalsobeviewedatmyTrunkingRadioComparisonChartpage.
Youwillalsoneedabetterantenna.Thestockrubberduckisn'tfabulous.RShastheCenterLoadedTelescopingWhipfor$15betterforVHF/UHF.The800MHzScannerAntennafor$25
100%betterfor700+MHz.YoumaybeabletofindothersonthewebbutRSisconvenientsoyoucanbuyitandtakeitbackinthesamedayifyoudon'tlikeit.Readthereviewsforeachatthe
site.

Theseradiosalsohavesoftwarethatwillenhanceand/orenableotherfeaturesnotpossiblewithjustthekeypadandhavebeennotedwhenknown.Myopinionisgetthesoftwareifyouhavea
lotoffrequencies.Withallthefeaturesandsettinginthesenewfangleddevicesitwillsaveyouhoursofprogrammingandfrustration.Itmayalsobeeasiertofigureoutthesoftwarethanthe
keypadsequences.Alphataggingisgreatbutmucheasierwiththesoftware.Becauseofthelimitedamountofkeysontheradios,programminga3letterwordtakesabout20keystrokesonmy
Pro97,ifyoucanrememberthesequenceanddon'tmakeamistake,afteryouprogramthebankname.SeewhatImean?Getthesoftware.Youhavetodishout$20bucksorsoforacable,the
softwareis$2030(aftera30dayfreetrial),andthereareplentyofnewsgroupsontheNetabouttheseradiostohelpyouhookuptothecomputerandworkthesoftware.

Allinall,theywillcomplimentyourscannercollection(providedyouhaveone).
Iwillassumeyouknowhowtoobtainthebasicinformationfromtheoriginalmanualsuchasfollowingsafetyprocedures,puttingthebatteriesin,connectingtheantenna,findingspecs,etc.and
concentrateonthemainfunctionsofthescanner.

Iherebyabsolvemyselffromanythingthathappenstoanyoneorthescannerasaresultoftheinformationyouwillbereading.Youarewelcometocopyand/orprintthesepagesandusethemin
thescanninghobbyaslongasyoudon'tchange,redistribute,orcharge/acceptmoneyforthem.

Checkbackoftenasthisdocumentwillbeupdatedandrevisedfromtimetotime.IhavetriedthebestIcantomakesureeverythingisaccurateherebutifImissedasteporyouseesomething

UnderstandingTrunking Contents
Trunkingsystemsletalargegroupof2wayradiousers(orevendifferentgroupsof2wayradiousers)efficientlyuseasetoffrequencies.Insteadofselectingaspecificfrequencyfora
transmission,theuser’sradioselectsaprogrammedtrunkingbankinthesystemwhenthatuserpressestheirPTT(pushtotalk)button.Thetrunkingsystemautomaticallytransmitsthecallon
thefirstavailablefrequency,andalsosends(onadifferentfrequencycalledaDataorControlchannel)acodethatuniquelyidentifiesthattransmissionasatalkgroupID(orjustID.)Sowhen
youaretrunktrackingasystem,youarelisteningtoactiveIDstransmittinginthesystem(eachusingthefirstavailablefrequencyinthesystem.)Trunkingsystemsingeneralallocateanduse
fewerfrequenciesamongmanydifferentusers.
Sincethetrunkingsystemmightsendacallanditsresponseondifferentfrequencies,itisdifficulttolistentotrunkedcommunicationsusingaconventionalscanner.Thesescannersletyou
monitorthecontrolchannelfrequencysoyoucanhearcallsandresponsesforusersandmoreeasily"follow"conversationsthanwithaconventionalscanner.
Thesescannerstrunktrackthefollowingtypesofsystems:
MotorolaTypeI
MotorolaTypeII
MotorolaTypeIIiHybrid
MotorolaTypeIISmartnet
MotorolaTypeIISmartzone
MotorolaTypeIISmartzoneOmnilink
EDACSStandard(Wide)
EDACSNetworked(Wide)
LTRStandard
WhenyouprogramMotorolaandEDACSsystemfrequenciesintothescanner,onefrequencyisthecontrol(ordata)channel,andtherestarevoicefrequenciessharedbyalltheusers.There
maybe3or4frequenciesassignedas(primaryoralternate)controlchannelsbutonlyonecontrolchannelwillbeactiveatatime.ThesescannerswillallowyoutoprogramjustMotorolacontrol
channelsintothetrunkingsystemandthevoicechannelswillautomaticallybefound(butnotprogrammed).EDACSsystemsneedallthefrequenciesforthesystemprogrammedandinthe
correctLCN(LogicalChannelNumber)order.
Thecontrolchanneliscontinuallytransmittedtothefieldunitsandhasasoundsimilartolisteningtoaboatengineoverthephone(inmanualmode;youwon'thearthiswhenyouaretrunking
thesystem.)Thiscontrolchannelisalsoagoodchecktoseeifyoucantrunktrackthesystem.Ifyoucan'thearacontrolchannelwhenyoustepthroughthetrunkingfrequencies(inmanual
mode),youeitherdon'thaveallthefrequenciesoraretoofarawaytoreceivethecontrolchannelandthesystem.Motorolasystemsarelimitedtoamaximumof28frequenciespersystemor
site.EricssonEDACSsystemsarelimitedto25frequenciespersystemorsite.MotorolaandEDACSsystemscanbeeitheranalog,digital,ormixed(digitalandanalogtalkgroups).These
scannerscan'tmonitordigitalsystems.
LTRsystemsworkalittledifferently.LTRsystemstypicallydonothaveadedicatedcontrolchannel.Thistypeofsystemencodesalltrunkinginformationasdigitalsubaudibledatathat
accompanieseachtransmission.ThefrequenciesalsohavetobeinLCN(LogicalChannelNumber)orderorthecorrect'slot'forthesystemtotrunktrackproperly.TheRepeaterFinderToolwill
helpyoudeterminethecorrectorder.Eachrepeaterhasitsowncontroller,andallofthesecontrollersaresynchronizedtogether.Eventhougheachcontrollermonitorsitsownchannel,oneof
thechannelcontrollersisassignedtobeamasterthatallcontrollersreportto.Eachofthesecontrollerssendsoutadataburstapproximatelyevery10secondssothatthesubscriberunitsknow
thatthesystemisthere.Thisdataburstisnotsentatthesametimebyallthechannels,buthappensrandomlythroughoutallthesystemchannels.IfyoulistentothefrequenciesofanLTR
systeminmanualmode(nottrunking),oneverychannelinthesystemyouwillhearthisdataburstthatwillsoundlikeashortblipofstaticlikesomeonekeyedupandunkeyedaradiowithin
about500msec.LTRsystemsarelimitedto20frequenciespersystem.
TrunkscanningisbasicallyscanningIDsthatareprogrammedintoIDlocations(sameconceptasfrequenciesintochannels.)YoucanthentrunkscanjusttheprogrammedIDs.Trunktrackingis
searchingforallIDsinasystem(sameconceptassearchingforfrequenciesinaband.)

RadioReference.comhasanexcellentpageexplainingthevarioustypesoftrunkingsystemsinmoredetailhere.
UnderstandingBanks Contents
ChannelStorageBanks
Theradioshave10banksof100channels.Channelnumberingstartswith000andgoesto099inthefirstbank.Banksnumber09.Youcanalsoprogramyourtrunkingfrequenciesand
conventionalfrequenciesintothesamebankaswelltoutilizechannelspacebetter.

Useeachchannelstoragebanktogroupfrequencies,suchasthoseforpolice,fire,ambulance,aircraft,and/ortrunkingsystems.Forexample,yourpolicedepartmentmightuse20frequencies
whilethefiredepartmentuses15andatrunkedEMSsystemsuses5trunkedfrequencies.YoucouldprogramtheEMSfrequenciesstartingwithchannel000,(thefirstchannelinbank0),the
policefrequenciesstartingwithchannel005,andthefiredepartmentfrequenciesstartingwithchannel025.EDACSsystemshavetostartatchannels001,101,201,etc.andfollowaLCNorder
butyoucanstilluse000,100,200,etc.foraconventionalfrequency.

Foreachtrunkingbank,youcanputinoneEDACSsystem(withconventionalfrequencies),oroneMotorolasystemand/oranLTRsystem(withconventionalfrequencies).However,ifyoustorea
MotorolasystemandanLTRsysteminonebank,thebankmodehastobesettoMO(Motorola).IfitissettoLT(LTR),theMotorolacontrolchannelwillbreakthesquelchandhangthescanner
onthatchannel.
Also,
(1)ifyouscanthisbankinopenmode,youwillhearallMotorolaIDsandLTRtransmissions(IDswillbeincorrectbecausethebankissettoreceiveMotorolaIDs).
(2)IfyouscanthismixedbankinclosedmodewithMotorolaIDsprogrammed,youwillhearjusttheprogrammedMotorolaIDs.
(3)YouwillhearthedataburstsfromtheLTRsystemaboutevery5secondssoyoushouldsetthedelayforthesechannelsaccordingly.

Tip:Theoretically,youcouldalsoprogrammorethanone(ofthesametypei.e.Motorola)trunkingsystemintoabankaslongasyoucouldonlymonitoroneatatime,indifferentlocations,far
enoughapart,sothesystemyouaremonitoringwouldn'tinterferewiththeothersystem(whichwouldconfusetheradio).Butremember,thescannercanbesettodecodeonlyonetypeofID
(MO,ED,orLTR)perbank.
ServiceSearchBands
Thescannersalsohave6servicebandspreprogrammedwithfrequenciesand1limitsearchtoallowyoutocreateyourownsearchband.SearchbandsSR3(Police/Fire),andSR5(Amateur)
aredividedintogroupsorsubbandsoffrequenciesthatcanbeturnedonoroffwithinthebands.
UnderstandingIDs Contents
MotorolaIDscomeintwoformats:TypeIandTypeII.EachformatdisplaysandusesTalkGroupIDsinslightlydifferentways.TypeI/IIhybridsystemsusebothTypeIandTypeIIformatsforTalk
GroupIDs.

TypeIIDsareintheformatFFFSSwhereFFFisthefleetandSSisthesubfleet.TypeIsystemsareusuallyorganizedwithdifferentIDsassignedtodifferentfleets.Forexample,a
validfleet/subfleetIDidentifyingalldetectiveswithinapolicedepartmentmightbe00012,where000identifiesallpoliceIDsand12identifiestheDetectivedivision.Toproperlytrunka
TypeIsystem,youhavetoprogramthefleetmapforthesystem.
TypeIIIDsareidentifiedbya5digitnumber.Valid(programmable)TalkGroupIDsaredivisibleby16.

EDACSIDscomeintwoformats:AFS(AgencyFleetSubfleet)andDecimal.

AM,FM(NFM),CT(CTCSS),DC(DCS),MO(Motorola),ED(EDACS),orLT(LTR)mode.
IfthereceivemodeofthechannelissettoCT,PLcodesappearintheformatxxx.x,wherexxx.xisafrequencyinHz.
IfthereceivemodeofthechannelissettoDC,DPLcodesappearintheformatxxx,wherexxxisanoctalcode.

UnderstandingCTCSS/DCS 
ContinuousToneCodedSquelchSystem(CTCSS)andDigitalCodedSquelch(DCS)aretwomethodsusedtopreventinterferencebyotherradiocommunications.Yourscannercanreceive
transmissionsthatusethesecodes(ormorecommonlyreferredtoastones).
CTCSSandDCSsystemsallusesomeformofcodedsquelch.Codedsquelchtechniquesinvolvethetransmissionofaspecial'code'signalalongwiththeaudioofaradiotransmission.A
receiverwithcodedsquelchonlyactivateswhenthereceivedsignalhasthecorrect'code'.Thisletsmanyusersshareasinglefrequency,anddecreasesinterferencecausedbydistant
transmittersonthesamechannel.InallmajormetropolitanareasoftheUnitedStates,everyavailableradiochannelisassignedtomorethanoneuser.Publicsafetyradiosystemsonthesame
frequencyareusuallysetupatadistanceof40milesapart,ormore.Thismeansthatyoumayheartransmissionsfromadistantsystemwhenyourlocalsystemisnottransmitting.By
programmingtheCTCSStoneforalocalchannelthescannerwillnotstopontransmissionsfromthedistantsystem.Withfewexceptions,suchastheVHFAircraftandMarinebands,almost
everyotherVHForUHFradiosystemusessomeformofcodedsquelch.Byfar,CTCSSisthemostpopularmodeamongnontrunkedsystems.
FormoreinformationvisitRadioReference'srespectivepagesonCTCSSandDCS.
OpenandClosedModes 
Eachchannelbankcanbesettoopenorclosedmode.
Inopenmodethescannerwillreceive:
(1)allchannelsinAM,FM,CT,andDCmodes,thatarenotlockedout.
(2)allIDsinMO,EDandLTRmodes,eveniftheyarelockedoutintheIDlist.
Inclosedmodethescannerwillreceive:
(1)allchannelsinAM,FM,CT,andDCmodes,thatarenotlockedout.
(2)onlyIDsinMO,ED,andLTRmodesthatareprogrammedintotheIDlist,andnotlockedoutinthelist.
Inotherwords,
IfyouwanttohearallIDs,scaninopenmode.IfyouwanttohearspecificIDs,programthemintothescanlistsandscaninclosedmode.IfyouwanttohearspecificIDsandnothearother

SignalStalkerII Contents
Yourscanner'sSignalStalkerIIfeatureprovidesapowerfulnewtoolforyoutorapidlydetect,monitor,andstorefrequenciesfromnearbyradiotransmissions.TheSignalStalkerIIfeatureismore
sensitivethanportablefrequencycountersandwilldetecttransmissionsatagreaterdistance.SignalStalkerIIfunctionsbyrapidlysweepingthroughtheRFspectrumin1MHzsegments.IfRF
signalenergyisdetectedina1MHzsegment,SignalStalkerIIwillsweepthroughthe1MHzsegmentinfinerstepsuntilthesourceoftheRFsignalenergyisfound.TheSignalStalkerIIfeature
issimilarinfunctionalitytoportablefrequencycountersthatcostmuchmorethanyourscanner,butprovidesmanyadvantagesovertypicalportablefrequencycounters.Forexample:TheSignal
StalkerIIallowsyoutosweeptheentirerangeofyourscanner'sdesignfrequencies,oryoucanspecifyjustthosefrequencyrangesthatyouwishtosweep.
TheSignalStalkerIIfeaturecanbesettowatchforactivityonallbandfrequenciesorPolice/Firefrequenciesonly.Youcanturnon/offfrequencysubbands(groups).Youcanactivatethe
Attenuatorand/orturntheDelayonalso.Youcanlockout150frequencieswhilesearchingallbandsand50frequencieswhilesearchingPolice/Firefrequencies.
SpecialSignalStalker
YoucanalsochangetheNormalSignalStalkerIIoperationtotheSpecialSignalStalkerIIoperation.IntheSpecialStalkeroperation,thefrequencyrangeisstilldividedby1MHzsegments.But,
ifyoulockout5frequencieswithina1MHzsegment,thescannerwillskipthatentiresegmentinsubsequentsweeps.
Certainsegmentsofthespectrumareusedbyhighpowertransmitters,suchaspagingtransmitters.YoucanpressL/OUTwhentheSignalStalkerIIstopsontheseundesiredtransmissionsto
preventtheSignalStalkerIIfromstoppingontheminfuturesweeps,however,theSignalStalkerIIwillstillseetheirsignalenergywhensweepingthroughthe1MHzsegment.Thiswillcausethe
SignalStalkerIItoexecuteanotherfinestepsearchofthe1MHzsegment.Ifyouhavelockedouttheundesiredtransmissions,theSignalStalkerIIwillnotstoponthemagainbuttheoverall
