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.

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).
