RECEIVE AND TRANSMIT
■
Split frequency operation
Split frequency operation allows you to transmit and
receive in the same mode on two different frequen-
cies. The split frequency operation is basically per-
formed using 2 frequencies on the main and sub
readouts.

Following is an example of setting 21.290 MHz for re-
ceiving and 21.310 MHz for transmitting.

q
Set 21.290 MHz (USB) in VFO mode.
w
Push [SPLIT] momentarily, then push [CHANGE]
for 1 sec.
for 1 sec.
• The quick split function is much more convenient for
selecting the transmit frequency. See the next section
for details.
for details.
• The equalized transmit frequency and “

on the LCD.
• “TX” appears to show the transmit frequency’s readout.
e
Rotate the tuning dial while pushing [XFC] to set
the transmit frequency to 21.310 MHz.
the transmit frequency to 21.310 MHz.
• The transmit frequency can be monitored while pushing
[XFC] or using dualwatch.
r
Now you can receive on 21.290 MHz and transmit on
21.310 MHz.
21.310 MHz.
To change the transmit and receive frequencies, push
[CHANGE] to exchange the main and sub readouts.

DIRECT SHIFT FREQUENCY INPUT
The shift frequency can be entered directly.
The shift frequency can be entered directly.
q
Push [F-INP].
w
Enter the desired shift frequency with the digit
keys.

• 1 kHz to 1 MHz can be set.
• When you require a minus shift direction, push [ • ] in
• When you require a minus shift direction, push [ • ] in
advance.
e
Push [SPLIT].
• The shift frequency is input in the sub readout and the
split function is turned ON.
[EXAMPLE]
DUALWATCH FUNCTION
The dualwatch function is convenient for tuning the
transmit frequency while monitoring both frequencies
used for transmitting and receiving.

SPLIT LOCK FUNCTION
Accidentally releasing the [XFC] switch while rotating
the tuning dial changes the receive frequency. To pre-
vent this, use both the split lock and dial lock func-
tions to change the transmit frequency only. The split
lock function cancels the dial lock function while push-
ing [XFC] during split frequency operation.
