Introduction
This manual provides technical information neces-
sary for servicing the FT-950 HF/50 MHz Trans-
ceiver.
Servicing this equipment requires expertise in han-
dling 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 com-
ponents, and the other has either a mixture of both
chip and leaded components (trimmers, coils, elec-
trolytic capacitors, ICs, etc.), or leaded components
only.
While we believe the technical information in this
manual to be correct, VERTEX STANDARD as-
sumes 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 in-
consistencies in the technical information would be
appreciated.
