1 KeyFeatures
TheANDROMEDA/ANAN‐7000DLEMKIIi5/i7AmateurRadioTransceiverisamoderndirect‐down‐
conversion[DDC]receiver,anddirect‐up‐conversion[DUC]transmitter,SoftwareDefinedHF
transceiverplus6Meters.ANDROMEDAhasaproudheritagefromtheTAPRHermesTransceiver
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PureSig nal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
 IndependentBPFsand6MLNAsforeachADC;optiontogroundADC2onTX
 ImprovedTXSNRandhigherdutycycleTX
