As shipped from the factory, the FT-991 TX/RX system for CW is configured for "Semi-break-in" operation.
However, this setup may be changed to full break-in (QSK) operation using Menu item "057 CW BK-IN". With
full break-in QSK, the TX/RX switching is quick enough to hear incoming signals in the spaces between the dots
and dashes of your transmission.

Menu.
2. Rotate the MULTI knob to select Menu item "057
CW BK-IN".
3. Press the [ SELECT ] button, then rotate the
MULTI knob to set this Menu item to "FULL".
4. When your adjustments are complete, touch [ EN-
TER ] on the LCD to save the new setting.
5. Press the MENU(SETUP) button or touch
[ BACK ] on the LCD to exit to normal operation.
A number of interesting and useful features are available during Electronic Keyer operation.

is 3:1 (a dash is three times longer than a dot).

Menu.
2. Rotate the MULTI knob to select Menu item "01
3 CW WEIGHT".

ue. The available adjustment range is a Dot/Dash
