FT-991 OperaTing Manual
Split-Frequency operAtion
A powerful capability of the
FT-991
is its exibility in Split Frequency operation using the VFO-A and VFO-B fre-
quency registers. This makes the
FT-991
especially useful for high-level DX-peditions. The Split operation capability is
very advanced and easy to use.
1. Rotate the Main Tuning Dial knob to set the desired
RX frequency.
2. Press the
A/B
button, then rotate the Main Tuning
Dial knob to set the desired split TX frequency.
3. Press the
A/B
button, then press the
SPLIT
button.
The VFO-B frequency will be shown in the TFT dis-
play and the LED indicators will appear as below:
VFO-A
RX
Indicator: “ON”
(LED glows Green)
VFO-A TX
Indicator: “OFF”
(LED Off)
VFO-B RX
Indicator: “OFF”
(LED Off)
VFO-B TX
Indicator: “ON” (LED glows Red)
SPLIT Button
TXW Button
A/B
Button
During Split operation, the VFO-A register will be used
for reception, while the VFO-B register will be used for
transmission. If you press the
SPLIT
button once more,
Split operation will be cancelled.
Advice:
During Split operation, pressing the
A/ B
button will
reverse the contents of VFO-A and VFO-B. Press the
A/B
button once more to return to the original fre-
quency alignment.
During Split operation you may listen to the TX fre-
quency temporarily while pressing the
TXW
button
located on the bottom left of the Main Tuning Dial
knob.
While pressing the
TXW
button during split opera-
tions, the frequency of transmit on VFO-B can be
changed.
During Split operation it is also possible to set VFO-
A and VFO-B to different Amateur bands if a multi
band antenna is used.
Quick Split Operation
The Quick Split feature allows setting a one-touch offset
of +5 kHz compared to the VFO-A frequency, to be ap-
plied to the transceiver VFO-B (transmit) frequency,

Start with regular transceiver operation on the VFO-A.
VFO-A RX
Indicator: “ON” (LED glows Green)
VFO-A TX
Indicator: “ON” (LED glows Red)
VFO-B RX
Indicator: “OFF”
(LED Off)
VFO-B TX
Indicator: “OFF”
(LED Off)
2. Press and hold in the
SPLIT
button for one second
to engage the Quick Split feature, and apply a fre-
quency 5 kHz above the VFO-A frequency to the
VFO-B frequency register.
The VFO conguration will then be:
VFO-A RX
Indicator: “ON” (LED glows Green)
VFO-A TX
Indicator: “OFF”
(LED Off)
VFO-B RX
Indicator: “OFF”
(LED Off)
VFO-B TX
Indicator: “ON” (LED glows Red)
