RECEIVE AND TRANSMIT 4
■Functions for receive
DIF 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 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
➀Adjust the [SHIFT] control for a minimum interfer- ence signal level.
•The audio tone may be changed while the IF shift is in use.
➁Set the shift control to its center position when there is no interference.

DRIT function
The RIT (Receive Incremental Tuning) function com- pensates for
➀Push [RIT].
•The [RIT] indicator lights red.
➁Rotate the
quencies.
•The transmit frequency is not shifted.
➂To cancel the RIT function, push [RIT] again.
•The [RIT] switch indicator goes out.
• Calculate function
The shift frequency of the RIT function can be added/subtracted to the displayed frequency.
While the RIT indicator is lit, push and hold [RIT] for 2 sec.
Note: The RIT function is not available in FM, WFM or AM modes regardless of the Initial Set mode set- ting (p. 51).
