RECEIVE AND TRANSMIT
E Functions for receive
© 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 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-Q/RTTY-O modes. The IF shift is not
available in FM and AM modes.
@ Adjust the [SHIFT] control for a minimum interfer-
ence signal level.
e The audio tone may be changed while the IF shift is in
use.
@Set the shift contro! to its center position when
there is no interference.
¢ Graphic display
The IF shift can be displayed graphically in graphic
display mode.
© Select IF shift in graphic display mode.
e Push [DISPLAY] 1 or 2 times when I or © is displayed.
e Push [MENU] one or more times to select the IF shift
display, fa (IF SHIFT appears briefly).
@The IF shift is graphically displayed and updated
as the [SHIFT] control is rotated.
© RIT function
The RIT (Receive Incremental Tuning) function com-
pensates for off-frequencies of communicating sta-
tions. The function shifts the receive frequency only,
up to +9.99 kHz in 10 Hz steps without moving the
transmit frequency. The [SUB/RIT] switch must be
set to RIT mode in advance (p. 48).
© Push [RIT].
¢ The [RIT] indicator lights red.
@ Rotate the [M-CH] control to cancel the off-fre-
quencies.
e The transmit frequency is not shifted.
@To cancel the RIT function, push [RIT] again.
e The [RIT] switch indicator goes out.
e 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.
