Yaesu FTdx5000 Series, Technical Supplement

Page: 1 / 282

Introduction
This manual provides technical information necessary for
servicing the FT
DX
5000 Series HF/50 MHz Transceiver.
Servicing this equipment requires expertise in handling
surface-mount chip components. Attempts by non-qual-
ified persons to service this equipment may result in
permanent damage not covered by the warranty, and
may be illegal in some countries.
Two PCB layout diagrams are provided for each dou-
ble-sided circuit board in the Transceiver. Each side of
is referred to by the type of the majority of components
installed on that side (“leaded” or “chip-only”). In most
cases one side has only chip components, and the oth-
er has either a mixture of both chip and leaded compo-
nents (trimmers, coils, electrolytic capacitors, ICs, etc.),
or leaded components only.
While we believe the technical information in this manu-
al to be correct, VERTEX STANDARD assumes no lia-
bility for damage that may occur as a result of typograph-
ical or other errors that may be present. Your coopera-
tion in pointing out any inconsistencies in the technical
information would be appreciated.
