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

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)

3. Press and hold in the

SPLIT

switch for one second

to increment the Sub (VFO-B) offset frequency an-

other +5 kHz.

The offset of VFO-B from VFO-A is programmed

via the Menu and is set to +5 kHz at the factory.

However, other offsets may be selected using the fol-
