introducedin2012.Itisbasedupontheestablished7000DLEmk2RF,DSPandPC,plusanintegrated
frontpanelwithradiocontrolsandtouchscreendisplay.

TheANAN‐7000DLEMKIIi5/i7modeliswithouttheAndromedafrontpanel,itiscapableofbeing
upgradedwiththeAndromedaFrontpanel.ThismodelsupersedesthepreviousIntegratedPC
ANAN‐7000DLEMKIIandincludesanumberofimprovementsandupgradestothehardware.

ANDROMEDAfirmwareupdatescanbeeasilyinstalledviatheradio’sstandardEthernetconnection,
eliminatingtheneedforspecialmechanicalorprogrammingadapters.Itisnotnecessarytoopen
theANDROMEDAcabinettoupdatethefirmware.A“Bootloader”switchhasbeenaddedtothe
backpaneloftheANDROMEDAforeaseoffutureupdates.

TheANDROMEDAtransceiverhasbeendesignedfortheTHETISPCSoftwareDefinedRadioprogram.
THETIShasthelatestSDRprocessingfromtheOpenHPSDRlineandisbasedontheprovenWDSP
libraries.Ithasfullsupportfordualreceivers,antennadiversityandPureSignalTXlinearization.
However,otherSDRprogramscouldbeusedincludingthosewrittenforWindows®,Linux,
MacOS/X®,Android,RaspberryPi,andotheroperatingsystems.Thecommandinterfacedtothe
frontpanelusessimplepublishedCATcommandsandotherprogramscouldbeadaptedtosupport
it.

1.1 Benefits
ANDROMEDA–Secondtonone!
UsingDirectDownConversionwithanultralowphasenoiseclockyieldsanRMDRof116dB
@2KHzseparation,thismeansthatcloseinweaksignalswillnotbemaskedbythe
receiver’sphasenoise.
Thetransmitterspecificationsarealsooffthechart,useofanew16‐bitDACwithanultra
lownoiseclocksourceresultsintransmitphasenoisebetterthananyotherproduct
availableinthemarket.
UseofLDMOSdriversandanoptimizedfinalAmplifierstagewithadaptivePredistortion
Algorithm(PureSignal)yieldstransmitIMDofbetterthan60dB,thisisatleast20dBbetter
thananyClassAtransmitterandover30dBbetterthanthecompetition.
Useoftwo16‐bitphasesynchronousADCsallowforadvancedapplicationssuchasDiversity
receptionforultimatenoisemitigationandeffectsofsignalfading.

TheANDROMEDAHF&6M100WSDRTransceiverofferstopofthelineperformanceinarugged
package,itisbasedontheworkoftheOpenHPSDRcommunity.

ThenewPAboardincorporatesthefollowingupdatesovertheprevious100Wgeneration:
PAGainredistributionforbetterIMD
ThermallycompensatedBias
Current/Voltage/TempSensors
Temperaturecontrolledinternalfanandoptionforexternalfan

1. Yourradiohardwareprovidesatransmit/receivepath.TherearetwofullyseparateRXpaths
eachwithitsownsignalconditioning,digitisingandprocessing.
2. Receivedsignalsarefiltered,attenuatedthendigitisedusingtwohighperformance
analogue‐to‐digitalconverter.TheA‐DconverterscoverthewholeHFband.Digital
processingintheFieldProgrammableGateArray(FPGA)convertsapartoftheHFbandto
zerocentrefrequency,andtransfersthedatatothePCviaEthernet.Thebandwidth
providedcanbeselected,butisusuallyintherange48KHz–1.536MHz.
3. ThePCrunstheTHETISprogram.THETIShastwohalves:auserinterface,andPCbased
signalprocessing.
4. THETISconnectstothereceiverdatastreamsandprovidesfurthersignalprocessingto
reducenoise,toselectthesignalsofinterestanddemodulatethem.Itsuserinterface
providesaviewofthebandactivityinthedownconvertedsignalisshown,andcontrolsto
tunetotherequiredsignalanddemodulateitsuccessfully.
5. Receivedaudioisroutedtotheinternalspeakers.AdditionalPCconnectedspeakersarealso
possible.
6. Ontransmit,THETISprovidestheinitialsignalprocessingtooptimisethetransmitsignal.
Audioprocessingisavailabletoenhanceavoicesignal.ACWkeyerisprovided.Sampled
dataissenttotheradiohardwareviaEthernet.
7. TheradiohardwareupconvertstheTXsignaltotherequiredfrequency,setsitssignallevel,
amplifiesandfiltersit.Amplifierlinearizationisavailable:asampleofthesignalfromthe
linearamplifierisdownconvertedbackthroughthereceiver,andcomparedwiththe
“intended”TXsignal.ThedifferenceisprocessedbyTHETIStoapplypre‐distortionsothat
thefinaloutputfromthelinearamplifierhasapproximately20dBlowerspurioussignal
contentthata“normal”HFtransmission.
