FUNCTIONS FOR TRANSMIT
When you find a DX station, an important consider-
ation is how to set the split frequency.
When you hold down [SPLIT] for 1 second, the Split
frequency function is turned ON, the Sub band fre-
quency is equalized to the Main band frequency, and it
becomes the initial transmit frequency.
This shortens the time needed to start the Split fre-
quency operation.
The Quick split function is ON by default. For your
convenience, it can be turned OFF in the Others set
screen (p. 15-13). In that case, [SPLIT] does not equal-
ize the Main and Sub band frequencies.
 Suppose you are operating at 21.290 MHz (USB) in
the VFO mode.
Hold down [SPLIT] for 1 second. q
The Split frequency operation is turned ON.
The Sub band frequency is equalized with the Main band
frequency.
F-INP
is displayed and the Sub band readout be-
comes the initial transmit frequency.
w Enter the desired offset frequency from the keypad
and then push [SPLIT], or set the transmit frequen-
cy by rotating [MAIN DIAL] while pushing [XFC], or
by rotating [SUB DIAL].
F-INP
disappears when [XFC] is pushed, or [MAIN
DIAL] or [SUB DIAL] is rotated.
Set the offset frequency by pushing [0] to [9]
[Example]
To transmit on a 1 kHz higher frequency:
- Push [F-INP], [1] and then push [SPLIT].
To transmit on a 3 kHz lower frequency:
- Push [F-INP], [•], [3] and then push [SPLIT].
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
[MAIN DIAL] changes the receive frequency. The Split
lock function is ON by default, but can be turned OFF in
the Others set screen. (p. 15-14)
q In the Split mode, push [LOCK] for both the Main
and Sub bands to activate the Split lock function.
w While pushing [XFC], rotate [MAIN DIAL] to change
the transmit frequency.
If you accidentally release [XFC] while rotating [MAIN
DIAL], the receive frequency does NOT change.
