■ RIT function
The RIT (Receive Incremental Tuning) function com-
pensates for off-frequencies of the communicating sta-
tion without moving the transmit frequency.
The RIT function can be used for the MAIN band only.
The function affects the MAIN band even when ac-
cessing the SUB band.
q Push [RIT] to turn the RIT function ON.
•“RIT” indicator appears.
w Rotate [RIT] control to cancel the off-frequencies.
•Rotate [RIT] control to the center position, after commu-
nication.
e Push [RIT] to cancel the RIT function.
•“RIT” indicator disappears.

■ IF shift function
The IF shift function electronically changes the pass-
band frequency of the IF (Intermediate Frequency) and
cuts out higher or lower frequency components of the
IF to reject interference. The function shifts the IF fre-
quency up to ±1.2 kHz in 100 Hz steps in SSB/CW
mode. The IF shift is especially useful in SSB opera-
tion and not available in FM mode.
The IF shift function can be used for the SUB band
using the SUB tuning dial function (p. 24)

MAIN band IF shift operation
q Set the [SHIFT] control to its center position when
there is no interference.
w Rotate the [SHIFT] control to adjust for minimum in-
terference signal level.
• The audio tone may change while the IF shift is in use.
DD
SUB band IF shift operation
q Assign the SUB band IF shift function to either [RIT]
or [SHIFT] control using the RIT/SHIFT set mode
(p. 68).
w Push [RIT] for 1 sec. to turn the SUB tuning dial
function ON.
•“RIT” indicator flashes.
e Rotate [RIT] or [SHIFT] control for a minimum inter-
ference signal level.
r Push [RIT] to cancel the SUB tuning dial function.
•“RIT” indicator disappears.
•Set [RIT] or [SHIFT] control to the center position after
the communication.
In satellite operation mode, the SUB tuning dial
function cannot be activated. Therefore, the [SHIFT]
control acts as an IF shift for the receive band (dis-
played in the upper area).
