Service Manual
For EXP Version
VX-1700 Series
Introduction
This manual provides the technical information necessary for servicing the VX-1700 HF Transceiver.
Servicing this equipment requires expertise in handing 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 board in this transceiver. Each side of the board
is referred to by the type of the majority of components installed on that side (“Side A” or “Side B”). In most
cases one side has only chip components (surface-mount devices), and the other has either a mixture of both
chip and leaded components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
As described in the pages to follow, the advanced microprocessor design of the VX-1700 Transceiver allows a
complete alignment of this transceiver to be performed without opening the case of the radio; all adjustments
can be performed from the front panel, using the “Alignment Mode” menu.
While we believe the information in this manual to be 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 information would be appreciated.
