5 ASSISTING YOUR SMOOTH QSO
Index Contents
3 Enter the frequency difference (the “split”) in the order
of kHz as specified by the DX station.
• If the frequency specified by the DXer is higher than now, enter
the specified frequency in the order of kHz using the numeric
and band-select keypad. Conversely, if the specified frequency
is lower, a value "0" must be prefixed to the frequency.
• For example, enter a value "5" if you need to increment the
frequency by 5 kHz, and enter a value "05" if you need to
decrement the frequency by 5 kHz.
• As a result, the "RX" (M) LED and "TX" (S) LED light green
and "SPLIT" LED lights yellow, and you can start the split
operation. Also, the offset frequency for the main band and
sub band frequencies appears on the sub screen as the ∆F
value.
Note:
◆ Pressing [TX] (M) switches from split operation to simplex
operation.
◆ To temporarily receive using the transmit frequency, use the TF-
SET function. {page 5-2}
ROTATE THE TUNING (M) CONTROL TO SEARCH FOR
THE TRANSMIT FREQUENCY.
To directly search for the transmit frequency by rotating
the Tuning control, follow the instruction below during the
reception on the main band of a signal from the DX station.
[RX](M) [RX](S)
[TX](S) [TX](M)
[CLR]
Tuning (M)
1 Press and hold [TX] (S).
The "SPLIT" LED blinks, each LED on the numeric and
band-select keypad also lights. An error will occur if the
frequency for the sub band is locked. Do this operation after
deactivating the frequency lock.
2 Rotate the Tuning (M) control to search for the
frequency.
The frequency can be changed even if the main band
frequency has been locked.
3 Press [TX] (S) to end.
• The frequency configured for the main band is also applied
to the transmit frequency of the sub band and you can start
the split operation.
• The "RX" (M) LED and "TX" (S) LED light, and the “SPLIT”
LED blinks. The offset frequency for the main band and sub
band frequencies appears on the main screen as the ∆F
value.
Note:
◆ If you wish to cancel the operation when the step 1 above has
completed, press either of [RX] (M), [TX] (M), or [CLR]. Also,
pressing [TX] (M) reverts the operating mode to simplex operation
from the split operation.
◆ To temporarily receive using the transmit frequency, use the TF-
SET function. {page 5-2}
SEARCHING WITH TF-SET ENABLED FOR THE
TRANSMIT FREQUENCY DURING RECEPTION
While pressing down the [TF-SET] key during the Split
operation using the sub band, the transmit frequency of
the main band can be changed by rotating the Tuning (M)
control. The status of the frequency can be monitored by
changing the frequency to receive.
To facilitate your QSO using the Split operation with a DX
station that has been piled up from many stations, use
the bandscope and the TF-SET to enable your operation
accurate and quick to tune the frequency used by the DX
station and the frequency that other stations are not using.
[TF-SET]
Tuning (M)
1 Press down [TF-SET].
The status of the transmit frequency can be monitored using
the main band.
2 While [TF-SET] is pressed down, rotate the Tuning
(M) or MULTI/CH control to increment or decrement
the frequency.
3 Release [TF-SET] to resume the reception using the
main band.
The transceiver resumes reception using the receiving
frequency configured for the main band.
Note:
◆ While you are pressing down [TF-SET], the frequency displays for
the main band and the sub band are reversed.
◆ You cannot change the frequency even with a rotation of the
Tuning (S) control while [TF-SET] is being pressed down.
◆ Pressing down [TF-SET] while the XIT function for the sub band is
active will add the XIT frequency to the displayed frequency for the
main band.
◆ Even if the frequency has been locked, the transmit frequency
displayed for the main band can be changed.
◆ While in Memory Channel Mode, and if a temporary change of a
memory channel is enabled, the frequency can be changed by
means of the TF-SET.
◆ While you are pressing down [TF-SET], you cannot change the
quick memory channel or clear the memory.
