Introduction
This manual provides technical information necessary for
servicing the Yaesu FT-817/FT-817 ND HF & V/UHF-Bands
Transceiver. It does not include information on installa-
tion and operation, which are described in the FT-817/
FT-817 ND Operating Manual provided with the transceiv-
er, or on accessories which are described in their manuals.
The FT-817/FT-817 ND is carefully designed to allow the
knowledgeable operator to make nearly all adjustments
required for various station conditions, modes and oper-
ator preferences simply from the controls on the panels,
without opening the case of the transceiver. The FT-817/
FT-817 ND Operating Manual describes these adjustments,
plus certain internal settings.
nents (trimmers, coils, electrolytic capacitors, packaged
ICs, etc.), or lead components only.
While we believe the technical information in this manu-
al is correct, VERTEX STANDARD 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 informa-
tion would be appreciated. VERTEX STANDARD reserves
the right to make changes in this transceiver and the align-
ment procedures, in the interest of technological improve-
ment, without notification of owners.
Servicing this equipment requires expertise in handling
surface mount chip components. Attempts by unquali-
fied persons to service this equipment may result in per-
manent damage not covered by warranty. For the major
circuit boards, each side of the board is identified by the
type of the majority of components installed on that side.
In most cases one side has only chip components, and the
other has either a mixture of both chip and lead compo-
