Introduction
This manual provides technical information necessary
for servicing the FT
DX
3000 HF/50 MHz Transceiver.
Servicing this equipment requires expertise in handling
surface-mount chip components. Attempts by non-
qualified 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 double-
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 other has either a mixture of both chip and leaded
components (trimmers, coils, electrolytic capacitors, ICs,
etc.), or leaded components only.
While we believe the technical information in this
manual to be correct, YAESU MUSEN assumes no
liability for damage that may occur as a result of
typographical or other errors that may be present. Your
cooperation in pointing out any inconsistencies in the
technical information would be appreciated.

3.0Ag-0.5Cu) should be used for repairs per-
formed on this apparatus. The solder stated
above utilizes the alloy composition required
for compliance with the lead-free specication,
and any solder with the above alloy composi-
tion may be used.
