RECEIVE AND TRANSMIT
Quick split function
When you nd a DX station, an important considera-
tion is how to set the split frequency.
When you push the [SPLIT] switch for 1 sec., split fre-
quency operation is turned ON, the sub readout is
equalized to the main readout frequency and enters
standby for transmit frequency input.
This shortens the time needed to start split frequency
operation.
The quick split function is ON by default. For your
convenience, it can be turned OFF in set mode.
(p. 69) In this case, the [SPLIT] switch does not
equalize the main and sub readout frequencies.
q Suppose you are operating at 21.290 MHz (USB)
in VFO mode.
w Push [SPLIT] for 1 sec.
Split frequency operation is turned ON.
The sub readout is equalized to the main readout fre-
quency.
The sub readout enters standby for transmit frequency
input.
e Rotate the tuning dial to set the transmit fre-
quency; or, input the transmit frequency using the
keypad and [ENT]; or, input a shift frequency using
the keypad and [SPLIT].
The transmit frequency can be monitored while pushing
[XFC] or using dualwatch.

When you are searching for DX stations and you
suspect that a DX station may say up X kHz for
their receive frequency:
OPERATION 1
q Push [SPLIT] for 1 sec. to standby for split opera-
tion.
w If the DX stations operator says up 10 kHz:
Push [1], [0] then [SPLIT].
Or, rotate the tuning dial.
OPERATION 2
If the DX stations operator says down 5 kHz be-
fore you enter standby for split operation:
Push [F-INP], [], [5] then [SPLIT].
The split function is turned ON and 5 kHz down fre-
quency is entered in the sub readout.
PRACTICAL EXAMPLE
When you receive a pile-up and you want to start
split frequency operation to simplify picking out sta-
tions:
q Push [SPLIT] momentarily and push [CHANGE]
for 1 sec.
The sub readout frequency is equalized to the main
readout frequency and “” appears.
w Rotate the tuning dial to set your receive fre-
quency in the main readout.
e Announce your receive frequency.
r After you catch one of the calling stations call
signs, push and hold the PTT switch to respond.
While pushing [XFC], you can monitor your transmit
frequency.
