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/M] is available when M-2 appears.
• [F-2 A/B] is available when M-1 appears.
w Push [F-1 SPL] momentarily (in the M-1 menu)
to turn the split function ON, then hold down [F-2
A/B] (M-1) for 1 second.
• 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 holding down [F-4 XFC]
(M-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
holding down [F-4 XFC].
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/B] (M-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 SPL] (M-1) on the transceiver's front
panel.
• The shift frequency is input to the sub readout and the

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