Split Frequency Operation - Icom IC-7000 Instruction Manual

FUNCTIONS 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 VFO frequencies (VFO A and VFO B) 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 Select VFO A and set the frequency to 21.290 MHz
(USB).
• [F-4 V V / / M M ] is available when M M - - 2 2 appears.
• [F-2 A A / / B B ] is available when M M - - 1 1 appears.
w Push [F-1 S S P P L L ] momentarily (in the M M - - 1 1 menu) to
turn the split function ON, then push and hold [F-2
A A / / B B ] (M M - - 1 1 ) for 1 sec.
• The equalized transmit (VFO B) frequency and "
appear on the LCD.
• The quick split function is much more convenient for
selecting the transmit frequency. See the next page for
details.
e Rotate [DIAL] while pushing and holding [F-4
X X F F C C ] (M M - - 1 1 ) to set the transmit frequency to 21.310
MHz.
• [XFC] on the HM-151 can also be used.
• The transmit frequency can be monitored while pushing
and holding [F-4 X X F F C C ].
r Now you can receive on 21.290 MHz and transmit
on 21.310 MHz.
To swap the transmit and receive frequencies, push
[F-2 A A / / B B ] (M M - - 1 1 ) to exchange the VFO A and VFO B.

DIRECT SHIFT FREQUENCY INPUT
The shift frequency can be entered directly.
q Push [F-INP/ENT] (HM-151).
w Enter the desired shift frequency with the digit
keys.
• 1 kHz to 1 MHz shifts can be entered.
• When you require a minus shift direction, push [50/•]
e Push [F-1 S S P P L L ] (M M - - 1 1 ) on the transceiver's front
panel.
• The shift frequency is input to the sub readout and the

[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
and holding [F-4 X X F F C C ] (M M - - 1 1 ) during split frequency
operation.
The dial lock's effectiveness during split frequency op-
eration can be selected in the miscellaneous (others)
set mode for both receive and transmit frequencies;
or only the receive frequency. (p. 129)
