52 FT-857D Operating Manual
CW TRANSMISSION
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 instructions in this section.
1. Insert your key’s plug into the rear-panel KEY jack.
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 injection.
3. Press the
[
FUNC
]
key momentarily, then rotate the SELECT
knob to select Multi-Function Row “j”
[
SPOT, BK, KYR
]
; press
the
[
B
](
BK
)
key to engage the “break-in” system; the “” icon
will appear at the left side of the “BK” notation.
4. When you close the key (or activate your computer-generated keying interface by what-
ever means), the transmitter will automatically be engaged. When you have finished
sending, the receiver will return, after a brief delay (see next section).
5. The CW “hang time” (the delay after the last character is sent, until the transceiver
switches to the receive mode) can be adjusted using the Menu Mode. To adjust the CW
hang time:
Press and hold in the
[
FUNC
]
key for one second to enter the Menu mode.
Rotate the SELECT 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 characters that are being sent).
When you have set the desired delay, press and hold in the
[
FUNC
]
key for one
second to save the new setting and exit to normal operation.
6. To practice your CW sending (without transmitting), press the
[
B
](
BK
)
key to make the
” icon disappear. Now, pressing the key will cause the CW sidetone to be heard, but
your radio will not be transmitting a signal on the air.
7. 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 second. 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 arbitrary scale of “0” ~ “100,” the
default value is “50.”
When done, press and hold in the
[
FUNC
]
key for one second to save the new
setting and exit to normal operation.
8. You also can adjust the CW sidetone pitch using Menu Mode No-027
