HF / VHF / UHF
All Mode Transceiver
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.
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-
