[
BK-IN

displayed by pressing the
F(M-
LIST)
button is turned off for now.
1. Press the
MODE
button, then touch
[
CW-LSB

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
”.
