144/430 MHz Dual-Band Digital Transceiver
FT2DR/DE
Introduction
This manual provides the technical information necessary for ser-
vicing the FT2DR/DE 144/430 MHz Dual Band Digital 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 warranty, 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, electrolytic capacitors,
ICs, etc.), or leaded components only.
While we believe the information in this manual to be correct,
YAESU 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.

0.5Cu) should be used for repairs performed on this
apparatus. The solder stated above utilizes the alloy
composition required for compliance with the lead-free
specication, and any solder with the above alloy com-
position may be used.
