6.3 Advanced Configuration

6.3.1 Required RF Output Delay (TX Delay)

TheTunerGeniusXL firmwaremanagesalltunerstatetransitions.However,theOperatetoTransmittransition

requiresthattheexciterslightlydelayemittingRFuntilthetransitioniscomplete.Therefore,theTunerGenius

XLrequiresaminimumdelayof20milliseconds(20ms)betweenthetimethekeyingsignalarrivesatthe

tuner

andthearrivaloftheexciterRFsignal.Thistimedelayisnecessaryforthetuner tocompleteallpreparations

toacceptasignalsafely.Thefollowingsectionsprovidedetailedinformationaboutsettingthedelay.

6.3.1.1 FLEX 6000-Series

WhenkeyingthetunerwithFLEX6000SeriestransceiversusingLANkeying,a[TXDelay]valueshouldbesetto

aminimumof20millisecondstoallowthetunertoselectthecorrecttuningsolution.



i–AbestpracticeistocreateaTunerGeniusXLTXProfilefor

yourFLEX‐6000Seriestransceiverandloadthat

whenusingtheTunerGeniusXL.

6.3.1.2 TX Delay for Other Exciters

WhenkeyingthetunerwithotherthanFLEX6000Seriestransceivers,youwillneedtousearadioconfiguration

orsettingtodelayRFgenerationbyatleasttwentymilliseconds(20ms)afterthekeyingsignal(PTT)issentto

thetunerbytheexciter.

Pleaseconsultthemanualforyourtransceiver

orexcitertoenableandconfigure thetransmitdelay. 

6.3.1.3 Exciters Without a TX Delay Adjustment

Iftheexciterdoesnotsupportatransmitdelay,thenconfigurethetunerandexciterinthefollowingway:

 Connectthekeyingdevice(micPTTswitch,footpedal,etc.)totheappropriateTunerGeniusXLPTT

Input.Theappropriateinputisthesametunerport(AorB)wherethe

exciteroutputisconnected.
