© IF SHIFT CONTROL [SHIFT]
e Shifts the center frequency of the main band IF in
SSB and CW modes. (p. 22)
- The shift frequency range: +1.2 kHz in 100 Hz steps.
Can be used as the sub tuning dial, sub band RIT
control or sub band IF shift control according to the
selection in set mode with the [RIT] switch. (p. 20)
- See the description on the previous page for details.
What is the IF shift control?
The IF shift electronically changes the IF passband fre-
quency to reject interference. The IF shift is especially ef-
fective in SSB operation and is not available in FM
operation.

€ CALL SWITCH [CALL¢SPLIT-RIT]
@ Calls up the call channel. (p. 36)
e Turns the RIT function ON and OFF while
in satellite mode. (p. 39)
e Turns the split function ON and OFF after
pushing [FUNC]. (p. 26)
- This function is available in VFO mode only.
@ VFO SWITCH [VFO+¢A=B] (p. 17)
VFO e Selects VFO mode and toggles VFO A
and B.
When pushed for 2 sec. after pushing
then [FUNC], equalizes the contents (fre-
cari ;
quency, operating mode, etc.) of the two

ush and :
hold - The rear (undisplayed) VFO contents are
equalized to the front (displayed) VFO con-
tents.

@ MEMORY SWITCH [MEMO-MPVFO] (p. 33)
e Selects memory mode.
-When the selected channel is not pro-
grammed, a selected band name (140 or
400) appears 2 sec. after the selection.
Zan °While pushed and held, the tuning dial
