Inroduction and description
This
manual
describes
the
installation,
operation,
and
maintenance
of
the
HF+6m
solid-state
linear
power
amplifier
ACOM
700S.
ACOM
700S is
a
state-of-the art linear
amplifier, covering the
amateur
bands
from
1.8
to
54MHz
with
700W output power
(PEP
or continuous carrier)
with less than 40W of drive. The amplifier operating
information is shown on a multi-functional, high resolution color display. ACOM 700S may by controlled
either by the six front panel buttons or remotely
–
via an
RS232
port.
NOTE
ACOM 700S
is
designed
to
work
with the ACOM 04AT Remote
Automatic
Antenna
Tuner.
The
connection
of
ACOM04AT
will
make
accessible
the
features
that
are
inactive
onthe
amplifier
display
when
ACOM
700S operates without
ACOM 04AT. The operation of ACOM 700S with ACOM 04AT
is described in the ACOM 04AT Operation Manual.

all
transceiver
models
available
on
the

does
not
need
any
special
signals:
„ground on transmit“

4
0W
of RF drive power is sufficient.
•
Broadband input circuit, providing a perfect transceiver load with SWR below
1.2:1
(typically
1.1:1),
without retuning throughout the whole frequency range from
1.8
to
54MHz.
