Jack
This is the DC power supply connection for the trans-
ceiver, used when operating the transceiver with an ex-
ternal power supply. Use the supplied DC cable to con-
nect this jack to the car battery or DC power supply,
which must be capable of supplying at least 22A @ 13.8
VDC. For base station operation, the optional
FP-30
External AC power supply may be attached to the bot-
tom of the transceiver and connect the output pigtail of
the
FP-30
to this jack.
GND
Terminal
For best performance and safety, this Ground lug may
be connected to a good earth ground using a short, heavy,
braided cable.
CAT
/LINEAR
Jack
This 8-pin mini-DIN jack is used for connection to the
FC-30
External Automatic Antenna Tuner or
ATAS-100/
-120
Active-Tuning Antenna System. It is also used for
interfacing to a personal computer for control of the trans-
ceiver using the
CAT
system, and for interconnection
to the
VL-1000
Linear Amplifier.
ACC
Jack
This 3.5-mm 3-pin jack accepts external ALC (Automatic
Level Control) voltage from a linear amplifier on the tip
connection, and accepts a “Transmit Request” command
on the ring connection. The main shaft is the ground re-
turn.
The “TX Request” connection, when shorted to ground,
puts the
FT-897D
into the transmit mode, and sends out
a steady CW carrier, for linear amplifier or manual an-
tenna tuner adjustment.

Jack
This 3.5-mm, 3-pin jack is used for connection to a CW
keyer paddle or a straight key.
EXT SPKR
Jack
This 3.5-mm, 2-pin jack provides variable audio output
for an external speaker. The audio output impedance at
this jack is 4
Ω
~ 16
Ω
and the level varies according to
the setting of the front panel’s
AF
control.
