Cw Mode Operation; Setup For Straight Key ( And Straight Key Emulation ) Operation - Yaesu FT-991A Operating Manual

CW Mode Operation

The powerful CW operating capabilities of the FT-991A 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 85.
 As shipped from the factory, the
RX system for CW is configured 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 switching 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 traffic 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 74 ) .
 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
FT-991A TX/
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-991A to a computer, CW can
be operated using free or commercially available
software and setting Menu item "060 PC KEYING".
