Setting this receive-only mode will bypass the TGXL tuning solution when the exciter is in receive mode. This fea-
ture is useful when you have multi-band antennas and want to monitor other bands simultaneously using your
FlexRadio.
BandConfigurator(ButtonandDialog)
TheBandConfigurationdialogallowstheusertoselectrangesoffrequenciesthatthetunerwillselectively
ignoreandsettheminimumSWRthatwillbeconsideredagoodmatch.Forexample,supposean80Mantenna
isresonantat3750kHz.Inthatcase,frequenciesnear
thisvaluecanbebypassedbyselectingtheEnable 
Bypasscheckboxinthe80Mrow,thenentertherangeofthebypassintheBypassStartandBypassStop
columns.NotetheuseofKHzinthesecolumns.ThePortBtabisonlyvalidfortheSO2Rswitching

MinimalSWR
TheMinimalSWRvalueisusedasatargetbythetunersolutionalgorithm.Thisfeaturegivestheoperatorsome
controloverthetargetSWR;however,itdoesnotensurethetunerwillfindanimpedancematchresultingin
thedesiredSWR.Theselectedvaluemayalso
givetheoperatorsomecontroloverhowlongittakesfora
solutiontobefound.Forexample,alowervaluemaytakelongerthanahighervalueforthetunertofinda
match.
i–Notethatsettingthetunertofindthelowestpossiblevalueisenticingtheperformancegainofa
