FUNCTION FOR TRANSMIT

■ Split frequency operation

Split frequency operation allows you to transmit and
receive in the same mode on two different frequencies.
The split frequency operation is basically performed
using 2 frequencies on the main and sub readouts.
The following is an example of setting 21.290 MHz for
receiving and 21.310 MHz for transmitting.
q Set 21.290 MHz (USB) in VFO mode.

• The quick split function is much more convenient for
selecting the transmit frequency. See the next page for
details.

e Rotate the tuning dial while pushing [XFC] to set
the transmit frequency to 21.310 MHz.
• The transmit frequency can be monitored while pushing
[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.
q Push [(F-INP)ENT].
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
advance.
e Push [SPLIT].
• The shift frequency is input in the sub readout and the
split function is turned ON.

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.
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. 100)
