RECEIVER ACCESSORIES
IF SHIFT
The receiver’s IF SHIFT feature is an effective interference-reduction tool, which allows
you to shift the passband response higher or lower without changing the pitch of the incom-
ing signal.
1. Press the switch for one second to acti-
vate the IF SHIFT feature. A “ ”, “ ,” or
“ ” icon will appear at the right of the fre-
quency display to indicate the IF SHIFT’s
current position.
2. Rotate the knob, as needed, to reduce
or eliminate the interference.
3. To turn the IF SHIFT feature off, again press the switch
for one second. The last setting of the IF SHIFT control will be
retained until you change it again.
4. If you wish to make a more permanent shift in the receiver’s IF
passband, use Menu #54 (LSB) or #55 (USB) in the “Extended
Menu.” This allows you to set up a higher or lower listening
pitch, if you prefer such as compared to the default passband
response. See page 68.
Engaging of the IF Shift feature does not disable the set-
ting of the Clarifier control. With the IF Shift activated,
press the switch momentarily to switch to Clarifier operation.
