Split Frequency Operation - Icom IC-718 Instruction Manual

Split frequency operation

Split frequency operation allows you to transmit and
receive in the same mode on two different frequen-
cies. Split frequency operation is 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.
w Push [SPLIT] momentarily, then push and hold
[CHANGE] for 1 sec.
• The quick split function is much more convenient for
selecting the transmit frequency. See the next section
for details.
• The equalized transmit frequency and "
appear on the LCD.
• [SPLIT] indicator lights.
• " " appears to show the transmit frequency read-
out.
e Rotate the main dial while pushing [XFC] to set the
transmit frequency to 21.310 MHz.
• The transmit frequency can be monitored while push-
ing [XFC].
r 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.
CONVENIENT
• 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 negative shift direction, push
in advance.
e Push [SPLIT] to input the shift frequency 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 (p. ??)
Accidentally releasing [XFC] while rotating the main
dial changes the receive frequency. To prevent this,
use both the split lock and dial lock functions to
change the transmit frequency only. The split lock
function cancels the dial lock function while pushing
[XFC] during split frequency operation.
The dial lock's effect during split frequency operation
can be selected in the set mode for both receive and
transmit frequencies; or only the receive frequency.
