ASSISTING YOUR SMOOTH QSO 5 RIT/XIT FUNCTIONS (FINE-TUNING FUNCTIONS FOR TRANSMIT AND RECEIVE FREQUENCIES) RIT (FINE-TUNING OF RECEIVE FREQUENCIES) RIT is a function that fine-tunes the receive frequency in steps of 10 Hz up to ±9.999 kHz without changing the transmit frequency. Use this function if the transmit frequency of the station with which you are working fluctuates. If the FINE mode is active, the RIT offset frequency can be adjusted in steps of 1 Hz. RIT functions in the same manner on all modes while the VFO or memory channel mode is in use. XIT (FINE-TUNING OF TRANSMIT FREQUENCIES) XIT is a function that fine-tunes the transmit frequency in steps of 10 Hz up to ±9.999 kHz without changing the receive frequency. If the FINE mode is active, the XIT offset frequency is adjusted in steps of 1 Hz. 1 Press [XIT]. The "XIT" LED lights, and the XIT offset frequency appears. 2 Rotate the RIT/XIT control. • The XIT transmit frequency can be fine-tuned. • To clear the XIT offset frequency, press [CL]. The XIT offset frequency instantly reverts to zero. 3 Press [XIT] to exit. XIT is deactivated. The current transmit frequency reverts to the previous transmit frequency in step 1. 1 Press [RIT]. The "RIT" LED lights, and the RIT offset frequency appears. 2 Rotate the RIT/XIT control. The RIT receive frequency can be fine-tuned. To clear the RIT offset frequency, press [CL]. The RIT offset frequency instantly reverts to zero. 3 Press [RIT] to exit. You can disable the RIT. The current receive frequency reverts to the previous receive frequency in step 1. Note: ◆◆The RIT control operates on the receive frequency for the main band. XIT SHIFT This is a function for shifting from operation using XIT to the split mode at one touch. 1 Press and hold [XIT]. When the TX frequency that is adjusted using XIT is set to a TX band, the operation switches to the split mode at the same time. The XIT frequency is then cleared and the XIT function is turned off. Note: ◆◆When RIT is on, RIT also turns off. RIT SHIFT This is a function for setting the frequency adjusted with RIT to an RX band. 1 Press and hold [RIT]. The RX frequency that is adjusted using RIT is set to an RX band. The RIT frequency is then cleared and the RIT function is turned off. Note: ◆◆When XIT is on, XIT also turns off.

RIT/XIT FUNCTIONS ±FINE-TUNING FUNCTIONS
FOR TRANSMIT AND RECEIVE FREQUENCIES²
RIT ±FINE-TUNING OF RECEIVE FREQUENCIES²
RIT is a function that fine-tunes the receive frequency
in steps of 10 Hz up to ´9.999 kHz without changing
the transmit frequency. Use this function if the transmit
frequency of the station with which you are working
fluctuates.
If the FINE mode is active, the RIT offset frequency can
be adjusted in steps of 1 Hz. RIT functions in the same
manner on all modes while the VFO or memory channel
mode is in use.

You can disable the RIT. The current receive frequency
reverts to the previous receive frequency in step 1.
Note:
◆

control operates on the receive frequency for the main
band.
RIT SHIFT
This is a function for setting the frequency adjusted with
RIT to an RX band.

.
The RX frequency that is adjusted using RIT is set to an RX
band. The RIT frequency is then cleared and the RIT function
is turned off.
Note:
◆
When XIT is on, XIT also turns off.
XIT ±FINE-TUNING OF TRANSMIT FREQUENCIES²
XIT is a function that fine-tunes the transmit frequency
in steps of 10 Hz up to ´9.999 kHz without changing the
receive frequency. If the FINE mode is active, the XIT
offset frequency is adjusted in steps of 1 Hz.

•
The XIT transmit frequency can be fine-tuned.
•
To clear the XIT offset frequency, press
[CL]
. The XIT offset
frequency instantly reverts to zero.
3
Press
[XIT]
to exit.
XIT is deactivated. The current transmit frequency reverts to
the previous transmit frequency in step 1.
XIT SHIFT
This is a function for shifting from operation using XIT to
the split mode at one touch.
1
Press and hold
[XIT]
.
When the TX frequency that is adjusted using XIT is set to
a TX band, the operation switches to the split mode at the
same time. The XIT frequency is then cleared and the XIT
