Using the Built-in Electronic Keyer
As shipped from the factory, the FT-991A TX/RX system for CW is configured for "Semi-break-in" operation.
However, this setup may be changed to full break-in ( QSK ) operation by setting Menu item "056 CW BK-IN

tween the dots and dashes of your transmission.

4. When the adjustments are complete, touch [ EN-
TER ] on the LCD to save the new setting.
A number of interesting and useful features are available for use with the Electronic Keyer operation.
This Menu item may be used to adjust the dot/dash ratio for the built-in Electronic Keyer. The default weighting
is 3:1 ( a dash is three times longer than a dot ) .
1. Press the MENU ( SETUP ) button to engage the
Menu.
2. Rotate the MULTI knob to select Menu item "014
CW WEIGHT".

the MULTI knob to set the weight to the desired
