FUNCTIONS FOR TRANSMIT
2001 NEW
2001 NEW
■
Quick split function
When you push the [SPLIT] switch for 1 sec., split fre-
quency operation is turned ON, the undisplayed VFO
is automatically changed according to the plus/minus
shift frequency programmed in set mode (p. 83) or
equalized when 0 kHz (default value) is programmed
as the split shift frequency. Quick split operation is
turned ON by default but can be turned OFF in set
mode (p. 82).
q
Suppose you are operating at 21.290 MHz (USB) in
VFO A.
w
Push [SPLIT] for 1 sec.
• Split frequency operation is turned ON.
• The VFO and VFO B are equalized.
e
While pushing [XFC], rotate the tuning dial to set
the frequency offset between transmit and receive.
• When [XFC] is released, the receive frequency is indi-
cated.

Split offset frequency setting
By setting an often-used split frequency offset in ad-
vance, you can use the quick split function to select split
operation at the push of one switch.
Set the split offset frequency in advance in set mode
(p. 82, item 12). The example at right shows the split
offset is set to +0.020 MHz.
➥
Push [SPLIT] for 1 sec. to activate the quick split
function.
• The transmit frequency is offset from the receive fre-
quency according to the offset in set mode.
D
D
Split lock function
The split lock function is convenient for changing only
the transmit frequency. When the split lock function is
not used, accidentally releasing [XFC] while rotating the
tuning dial, changes the receive frequency. The split
lock function is ON by default, but can be turned OFF
in set mode.
q
While split frequency operation is ON, push
[LOCK/SPCH] to activate the split lock function.
w
While pushing [XFC], rotate the tuning dial to
change the transmit frequency.
• If you accidentally release [XFC] while rotating the tuning
dial, the receive frequency does NOT change.
