 ButtonText:ThetextthatwillbeshownontheBandButton.
 LOOffset(MHz):ThedifferencebetweenthetransverterlowfrequencyandtheIF
frequency.Forexample,on2m,youmightuse144‐28MHz=116.
 LOError(kHz):Thissettingallowstheusertocorrect
foranyerrorinthetransverter’s
oscillator.
 BeginFrequency(MHz):Thelowerfrequencyboundforthetransverter.
 EndFrequency(MHz):Theupperfrequencyboundforthetransverter.
 RXGain(dB):Amountofgaintoapplytotheincomingsignalstocompensateforgainwithin
thetransverter.Please
notethatthisisstillindevelopment.
 RXOnly:Ifthisboxischecked,theradiowillnottransmitwhileinthisconfiguredband.
 Power:SetstheDrivecontrolonPowerSDRtothisvaluewhenevertheVFOiswithinthe
configuredband.
 XVTRRFTX:
 DisablePA:
Disablestheinternal100WPowerAmplifier.LowlevelRFissentviatheXVTRTX
SMAconnectoronbackpanel.
 TheusermustmakecarefuladjustmentsusingthePAGainByBandusingtheVHFxx
spinnersandtheDriveleveltoinsurethetransverterseestheproperlevel.With
thePAGain
byBandspinnerssettotheirdefaultvalueof65.0andtheDrivesliderto100 theRFoutput
isapproximately10mWattheXVTRRFSMAconnector.
8.3 CATcontrol
ComputerAidedTransceiver(CAT)commandswerecreatedtoallowPCstocontrolradios.They
allowmostofthesettingsofaradiotobeaccessedusingsimpleserialcommands.Manydifferent
kindsofprogramusethem,andmanyexternaldevicesareavailable(e.g.autotuners)thatuse
them.
THETISsupportsCAT
commands,andcanhave4connectionsopenatanytime.Theseareaccessed
throughtheSetupform,CATControltab.
Establishingaconnectionissimple:
1. Connectanexternaldevice,ifyouhaveone.
2. IfyouareconnectingtoanotherprogramonthesamePC,youwillneeda
virtualCOMport
program
3. ChoosetheCATconnectiononTHETIS(THETIShasoneCATconnectionontheprimarytab,
andthreemoreonthe“CAT+”form.Theyareallthesame).
4. SettheporttotheportnumberofyourdeviceorVACcable
5. Setthebaudrate,
parity,dataandstopbitsappropriately(thereshouldbedocumentation
fortheproductyouareconnectingto)
6. ClickEnable
7. Andthat’sit–connectionwillbeestablished.
ThelistofCATcommandsusedbyTHETISandPowerSDRmrxpscanbedownloadedfromtheTAPA
HPSDRgithubrepository
[5].Thatdocumentexplainstheformatofthecommands.
Takecareifyourremotedeviceincludesan“Arduino”basedprocessor:NEVERopentheconnection
withthebaudratesetto1200.Thatwillcausethedevicetoeraseitsfirmware,requiringittobe
reprogrammed.
