TRANSMITTER OPERATION
Operation using Straight Key/External Keying Device
When using a straight key, an external electronic keyer, or a
computer-generated keying device, please follow the instruc-
tions in this section.
1. Insert your key’s (three-conductor) plug into the rear-
panel KEY jack.
6. You can adjust the CW sidetone volume level via Menu
Mode No-029
[
CW SIDE TONE
]
. To adjust the CW
sidetone volume level:
• While still in Multi Function Row “j”
[
SPOT, BK,
KYR
], press and hold in the [
B
](
BK
)
key for one sec-
ond. This is a “hot key” feature which will instantly
recall Menu Mode No-029
[
CW SIDE TONE
]
• Rotate the DIAL to select a new level; on the arbi-
trary scale of “0” ~ “100,” the default value is “50.”
• When done, press and hold in the
[
F
]
key for one
second to save the new setting and exit to normal
operation.
7. You also can adjust the CW sidetone pitch using Menu
Mode No-027
[
CW PITCH
]
. This adjustment also con-
trols the BFO offset (actual pitch of your transmitted
signal relative to your current receive frequency). To ad-
just the CW sidetone pitch:
• Press and hold in the
[
F
]
key for one second to enter
the Menu mode.
• Rotate the MEM/VFO CH knob to Menu Mode No-
027
[
CW PITCH
]
.
• Rotate the DIAL to select a new pitch tone/BFO off-
set. The available offset range is 400 ~ 800 Hz (de-
fault value is “700 Hz”).
• When done, press and hold in the
[
F
]
key for one
second to save the new setting and exit to normal
operation.
8. The FT-897D also has a “CW SPOT” feature, utilizing
the sidetone. Because the sidetone is a representation of
the actual pitch of your transmitted signal, it may be used
for zeroing in on another station. To activate the CW
SPOT tone, just press and hold in the
[
HOME
]
key for
one second while in the CW mode.
Pressing the [A](SPOT) key while in Multi
Function Row “j” [SPOT, BK, KYR] will also
activate the CW SPOT tone.

2. Press the MODE
(
)
or MODE
(
)
key, as needed, to
select one of the CW modes (CW/CWR).
The “CW” mode utilizes USB-side carrier injection,
while the CWR (Reverse) mode utilizes LSB-side in-
jection.
3. When you close the key (or activate your computer-gen-
erated keying interface by whatever means), the trans-
mitter will automatically be engaged. When you have
finished sending, the receiver will return, after a brief
delay (see next section).
4. The CW hang time can be adjusted using the Menu Mode.
To adjust the CW hang time:
• Press and hold in the
[
F
]
key for one second to enter
the Menu mode.
• Rotate the MEM/VFO CH knob to Menu Mode No-
024
[
CW DELAY
]
.
• Rotate the DIAL to select a longer or shorter delay
time (default: 250 ms). If the delay selection is set to
“FULL,” the transceiver will operate in the full break-
in mode (allowing you to hear between the charac-
ters that are being sent).
• When you have set the desired delay, press and hold
in the
[
F
]
key for one second to save the new setting
and exit to normal operation.
5. To practice your CW sending (without transmitting),
press the
[
B
](
BK
)
key to make the “Parentheses” disap-
pear. Now, pressing the key will cause the CW sidetone
to be heard, but your radio will not be transmitting a
signal on the air.
