Yaesu FTDX101MP Manual

HF/50 MHz TRANSCEIVER
FTDX101MP
FTDX101D
Introduction
This manual provides the technical information necessary
for servicing the FTDX101MP, FTDX101D HF/50 MHz
TRANSCEIVER.
Servicing this equipment requires expertise in handing
surface-mount chip components. Attempts by non-qualied
persons to service this equipment may result in permanent
damage not covered by the warranty, and may be illegal in
some countries.
While we believe the information in this manual to be cor-
rect, YAESU assumes no liability for damage that may oc-
cur as a result of typographical or other errors that may be
present. Your cooperation in pointing out any inconsisten-
cies in the technical information would be appreciated.
Important Note
This transceiver was assembled using Pb (lead) free solder, based on the RoHS specication.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The solder stated
above utilizes the alloy composition required for compliance with the lead-free specication, and any solder with the above alloy com-
position may be used.

Introduction and Precautions
Realignmentmayberequiredafterthecomponents
havebeenreplaced.
WerecommendthatauthorizedYaesuTechnicians,
whoareexperiencedwiththecircuitryandfully
equippedtoalignourproducts,performaligns.
Thosewhodoundertakeanyofthefollowing
alignmentsarecautionedto proceed at theirown
risk.Problemscausedbyunauthorizedaemptsat
realignmentarenotcoveredbythewarrantypoli-
cy.
Theneedforrealignmentshouldbedeterminedto
be absolutely necessary.
Thefollowing test equipment (and a thorough fa-
miliaritywithitscorrectuse)isnecessaryforcor-
rectrealignment. Most steps do not require allof
theequipmentlisted.Theinteractionsofsomead-
justmentsmayrequirethatmorecomplexadjust-
mentsbeperformedinasequence.Donotaempt
toperformonlyasinglestepunlessitisclearlyiso-
latedelectricallyfromallothersteps.Havealltest
equipmentreadybeforebeginning, and follow all
ofthestepsinasectionintheordertheyarepre-
sented.

Alignment Preparation & Precautions
A50-ohm RF Dummyload and in-line wameter
mustbeconnectedtothe“ANT”jackinallproce-
duresthatcallfortransmission,exceptwherespec-
ifiedotherwise. Correctalignmentisnotpossible
withanantenna.
Aftercompletingonestep,readthefollowingstep
todeterminewhetherthesametestequipment
willberequired.Ifnot,removetheunneededtest
equipmentbeforeproceeding.(exceptthedummy
loadandwameter).
Correctalignmentrequiresthattheambienttem-
peraturebe maintained constant between68°Fto
86°F(20°Cto30°C).Whenthetransceiveris
broughtintotheshopfromahotorcoldenviron-
ment,itshouldbeallowedtimeto come to room
temperaturebeforealignment.Also,thetestequip-
mentmustbethoroughlywarmedupbeforebegin-
ning.
Wheneverpossible,alignmentsshouldbemade
withoscillatorshieldsandcircuitboardsrmlyaf-
xedinplace.
