4 RECEIVE AND TRANSMIT
E 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.
© Set 21.290 MHz (USB) in VFO mode.

@ Push [SPLIT] momentarily, then push [CHANGE]
for 2 sec.
- The quick split function is much more convenient for
selecting the transmit frequency. See the next section
for details.
- Equalized transmit frequency and " Gili" appear on
the LCD.
- "3" appears to show the transmit frequency's read-
out.

(3) Rotate the tuning dial while pushing [XFC] to set
the transmit frequency to 21.310 MHz.
- The transmit frequency can be monitored while push-
ing [XFC] or using dualwatch.

@ Now you can receive on 21.290 MHz and transmit
on 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.
@ Push [F-INP].
© 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
advance.
(3) Push [SPLIT]. |
- The shift frequency is input in the sub readout and the
split function is turned ON.
[EXAMPLE]
To operate on 1 kHz

To operate on 3 kHz

DUALWATCH FUNCTION
The dualwatch function is convenient for tuning the
transmit frequency while monitoring both frequencies
used for transmitting and receiving.
CONVENIENT
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.
The dial lock's effectiveness during split frequency op-
eration can be selected in the set mode for both re-
ceive and transmit frequencies; or only the receive
frequency. (p. 57)
