Technical Supplement
50/144/430 MHz Triple-Band
Heavy Duty Submersible Transceiver
Introduction
This manual provides the technical information necessary for servicing
the VX-7R 50/144/430 MHzTriple-Band Heavy Duty Submersible Trans-
ceiver. 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 war-
ranty, and may be illegal in some countries.
Two PCB layout diagrams 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, and the other has either
a mixture of both chip and leaded components (trimmers, coils, electro-
lytic capacitors, ICs, etc.), or leaded components only.
While we believe the information in this manual to be correct, VER-
TEX STANDARD assumes no liability for damage that may occur as a
result of typographical or other errors that may be present. Your coop-
eration in pointing out any inconsistencies in the technical information
would be appreciated.
