Quick split function
When you find a DX station, an important considera-
tion is how to set the split frequency.
When you push and hold the switch for 1 sec.,
split frequency operation is turned ON and the trans-
mit frequency is equalized to the received frequency.
This shortens the time needed to begin split frequency
operation.
The quick split function is ON by default. For your con-
venience, it can be turned OFF in Others set mode.
(p. 12-12) In this case, the
switch does not
equalize the transmit frequency to the receive fre-
quency.
q Suppose you are operating at 21.290 MHz (USB) in
VFO mode.
w Push and hold for 1 sec.
• Split frequency operation is turned ON.
• The transmit frequency (unselected VFO’s readout) is
equalized to the receive frequency (selected VFO’s read-
out).
• “ ” indicator appears.
e Enter the desired offset frequency from the keypad
then push
, or set the transmit frequency
with the main dial while pushing [XFC].
• “ ” indicator appears when is pushed.
• Offset frequency setting with the keypad— example
To transmit on 1 kHz higher frequency:
- Push , then .
To transmit on 3 kHz lower frequency:
- Push , , then .
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 main dial, changes the receive frequency. The split
lock function is ON by default, but can be turned OFF
in set mode. (p. 12-13)
q While split frequency operation is ON, push [LOCK]
to activate the split lock function.
w While pushing [XFC], rotate the main dial to change
the transmit frequency.
• If you accidentally release [XFC] while rotating the main
dial, the receive frequency does NOT change.
