FT-991 OperaTing Manual
The powerful CW operating capabilities of the
FT-991
permit operation using an electronic keyer paddle, a “straight
key”, or a computer-based keying device.
Setup For StrAight key
(
And StrAight key eMulAtion
)
operAtion
Before starting, connect your key line(s) to the front panel
KEY
jack. Be sure
[
BK-IN
]
displayed by pressing the
F(M-
LIST)
button is turned off for now.
1. Press the
MODE
button, then touch
[
CW-LSB
]
or
[
CW-USB
]
on the TFT LCD display. The “
C-L
or “
C-U
icon will appear in the display. The CW
monitor is activated.

2. Rotate the Main Tuning Dial knob to select the de-
sired operating frequency.
3. Press the
F(M-LIST)
button, then touch
[
BK-IN
]
on the LCD to engage automatic activation of the
transmitter when you close the CW key. The Break-
in will be set to “
ON
”.
Advice:
When you close the CW key, the transmitter will
automatically be activated, and the CW carrier
will be transmitted. When you release the key,
transmission will cease, and after a brief delay,
receive will be restored. The delay time is user-
programmable per the discussion on page 83.
As shipped from the factory, the
FT-991
TX/RX
system for CW is congured for “Semi-break-in”
operation. However, using Menu item
056 CW
BK-IN TYPE
”, you may change this setup for full
break-in (QSK) operation, whereby the switch-
ing is quick enough to hear incoming signals in
the spaces between the dots and dashes of your
transmission. This may prove very useful during
contest and trafc handling operations.
4. CW operation using the CW key may now proceed.
Advice:
The CW sidetone audio level may be adjusted by
setting “MONITOR” (see page 72).
You may practice sending CW listening to the sidet-
one only, without having the signal transmitted out
over the air, if you press the front panel
F(M-LIST)
button to reveal the functions list on the TFT LCD
display, and then touch the [
BK-IN
] button to set
break-in to Off.
If you reduce transmit power via the [
RF PWR
]
function that may be displayed by pressing the
F(M-
LIST)
button, the ALC meter reading will increase;
this is normal and does not indicate any problem
whatsoever (because increased ALC voltage is being
used to lower the power).
To enable the keying operation in LSB/USB mode
and send the CW signal without switching to CW
mode, change Menu item “
055 CW AUTO MODE
”.
The same frequency may be displayed when switch-
ing between SSB mode and CW mode by setting
Menu item “
059 CW FREQ DISPLAY
”.
By connecting the
FT-991
to a computer, CW can
be operated using free or commercially available
software and setting Menu item “
060 PC KEYING
”.
