FT-100/-100D
HF & V/UHF Band
All Mode Mobile Transceiver
Introduction
This manual provides technical information necessary
for servicing the Yaesu FT-100/-100D HF & V/UHF-Band
Transceiver. It does not include information on installa-
tion and operation, which are described in the FT-100/-
100D Operating Manual provided with the transceiver,
or on accessories which are described in their manuals.
The FT-100/-100D 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-100/-
100D Operating Manual describes these adjustments, plus
certain internal settings.
Servicing this equipment requires expertise in handling
surface mount chip components. Attempts by unqualified
persons to service this equipment may result in perma-
nent damage not covered by warranty. For the major cir-
cuit 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-
nents (trimmers, coils, electrolytic capacitors, packaged
ICs, etc.), or lead components only.
While we believe the technical information in this man-
ual 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.
