RECEIVE AND TRANSMIT
Split frequency operation allows you to transmit and
receive on two different frequencies. Split frequency
operation uses 2 frequencies, one in VFO A and the
other in VFO B.
Following is an example of setting 7.057 MHz, CW
mode in VFO A (for receive) and 7.025 MHz, CW
mode in VFO B (for transmit).
Select VFO A and set the frequency to 7.057
MHz/CW.
•[(F-2)A/B] is available when M1 appears.
•[
(F-3)V/M] is available when M2 appears.
Push or push and hold [(F-1)SPL] in the M1 dis-
play.
Push [SPL]: activates split only.
Push and hold [SPL]: activates the quick split
below.
To change the receive frequency, rotate the main
dial; to change the transmit frequency, rotate the
main dial while pushing [(F-3)XFC].
•The transmit frequency can be monitored while pushing
[
(F-3)XFC].
•Split operation is now set for receive on 7.057 MHz/CW
and transmit on 7.025 MHz/CW.
To exchange the transmit and receive frequencies,
push [(F-2)A/B] in M1.
CONVENIENT
The G3 display conveniently shows the transmit fre-
quency during split frequency operation and [(F-3)Ñ]
allows you to change the transmit frequency.
•Split lock function
The split lock function is convenient for changing only
the transmit frequency. Otherwise, accidentally
releasing the [(F-3)XFC] switch while rotating the
main dial changes the receive frequency. The split
lock’s effectiveness can be selected in initial set
mode (item 12) for both receive and transmit fre-
quencies; or only the receive frequency. (p. 52)
D Quick split function
In M1, when you push [(F-1)SPL] for 2 sec., split fre-
quency operation is turned ON and VFO B is auto-
matically changed according to the plus/minus pre-
programmed shift frequency set in initial set mode (or
equalized when 0 kHz is programmed as the split
shift frequency). This shortens the time needed to
start split frequency operation—great for DX’ing.
The quick split function is ON by default. If desired, it
can be turned OFF in initial set mode (p. 51). In this
case, pushing [(F-1)SPL] for 2 sec. has the same
effect as pushing [(F-1)SPL] momentarily as in nor-
mal split operation.
PROGRAMMING SPLIT SHIFT FREQUENCY
Push [POWER] to turn power OFF.
While pushing [LOCK], push [POWER] to turn
power ON and enter initial set mode.
Select “SPL OFFSET” using [MENU], [M-CH] or
the [Y]/[Z] keys, then rotate the main dial to select
the desired split offset.
•The split offset can be selected from –4000 kHz to
+4000 kHz.
Note: This setting is not valid for FM operation. This
is because FM operation uses the duplex setting for
repeater operation (next page).
