5 COMMUNICATING AIDS COMMUNICATING AIDS 5 Split Operation The same frequency is used for both reception and transmission during normal communication. Select either VFO A or VFO B in this case. However, depending on the circumstances, a different frequency may be chosen for reception and transmission. In this case, it is necessary to use two VFOs. This is known as "split operation". "Split operation" is used in cases such as when using an FM repeater or when calling a DX station. 1 Press [SPLIT]. > lights up when the transceiver enters the split mode.

Split Operation
The same frequency is used for both reception and transmission
during normal communication. Select either VFO A or VFO B in
this case. However, depending on the circumstances, a different
frequency may be chosen for reception and transmission. In this
case, it is necessary to use two VFOs. This is known as
“
split
operation
”
.
“
Split operation
”
is used in cases such as when using
an FM repeater or when calling a DX station.

frequency specified by the DX station and the RX frequency,
perform the steps below while receiving signals from the DX
station.
1
Press and hold [SPLIT].
•
<<
>> starts to blink.
2
Enter the frequency specified by the DX station in
units of kHz.

If the frequency specified by the DX station is a positive value, enter
the specified frequency in units of kHz using the numeric keypad.
If the frequency specified by the DX station is a negative value,
enter a “0” at the beginning of the frequency value.
For example, if “+5 kHz” is specified, enter “5”. If “-5 kHz” is
specified, enter “0” followed by “5”.
After input is complete, the TX frequency is configured and split
operation is now enabled.

Press and hold [SPLIT].
•
<<
>> starts to blink.
2
Turn the Tuning control to search for a TX frequency.

F Display
This item displays the difference between the RX frequency and
TX frequency during split operation.
Configure in Menu [6-15]
“
Delta Frequency Display

Setting Value
Off/ On (default)
•
When the
⊿
F display is ON, <<
>> is displayed below
the TX frequency display during split operation.
•
When <<
>> is displayed below the TX frequency, the
band memory number on the right will not be displayed.
•
When RIT or XIT is ON, the
⊿
F value is the difference
between the TX frequency and the RX frequency with the
RIT or XIT frequency added.
Changing the split frequency using the [RIT/XIT]
control
While in the split mode with the RIT/XIT function set to OFF, the
split frequency can be adjusted by turning the
[RIT/XIT]
control.
Configure in Menu [3-12]
“

Frequency Offset while TX/ Both
TX Frequency Offset while RX:
Split transmission frequency
can be adjusted while receiving. While receiving signals from a
DX station, turning the
[RIT/XIT]
control changes the TX
frequency in advance to the frequency specified by the target
station.
RX Frequency Offset while TX:
Split reception frequency can
be adjusted while transmitting. While one’s own station is
transmitting as a DX station, turning the
[RIT/XIT]
control
changes the RX frequency in advance to the frequency
specified for the target station.
