40 FT-857 Operating Manual
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 and hold in the
[
CLAR
]
button for one sec-
ond to activate the IF SHIFT feature. An icon, such
as “ ”, “ ” (slightly shifted to the upper side),
“ ” (more shifted to the upper side), “ ”(slightly
shifted to the lower side),” or “ ” (more shifted to
the lower side)” icon will appear at the right of the
frequency display to indicate the IF SHIFT’s cur-
rent position.
2. Rotate the SELECT knob, as needed, to reduce or elimi-
nate the interference.
3. To turn the IF SHIFT feature off, again press and hold in
the
[
CLAR
]
button for one second. The last setting of the
IF SHIFT control will be retained until you change it again.
If you wish to make a more permanent shift in the receiver’s
IF passband, use Menu Mode No-015
[
CAR LSB R
]
(for LSB
mode) or No-017
[
CAR USB R
]
(for USB mode). This al-
lows you to set up a higher or lower listening pitch, if you
prefer such as compared to the default passband response.
See page 99.
