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 frequency up to ±1.2 kHz in 15 Hz steps in
SSB/CW/RTTY modes and up to ±250 Hz in 3 Hz
steps in CW-
ã
/RTTY-
ã
modes. The IF shift is not
available in FM and AM modes.
➀
Adjust the [SHIFT] control for a minimum interfer-
ence signal level.
• The audio tone may be changed while the IF shift is in
use.
➁
Set the shift control to its center position when
there is no interference.

The RIT (Receive Incremental Tuning) function com-
pensates for off-frequencies of communicating sta-
tions. The function shifts the receive frequency up to
±9.99 kHz in 10 Hz steps without moving the transmit
frequency. The [SUB/RIT] switch in Initial Set Mode
must be set to RIT mode in advance (p. 51).
➀
Push [RIT].
• The [RIT] indicator lights red.
➁
Rotate the [M-CH] control to cancel the off-fre-
quencies.
• The transmit frequency is not shifted.
➂
To cancel the RIT function, push [RIT] again.
• The [RIT] switch indicator goes out.
