INTERFERENCE REJECTION
IF NOTCH FILTER OPERATION
(
SSB/CW/RTTY/PKT/AM MODES
)
The IF NOTCH filter is a highly effective system that allows you to slice out an interfering beat note or other carrier signal
from inside the receiver passband.
1. Press the
[
NOTCH
]
button to activate the Notch filter.
The LED inside the
[
NOTCH
]
button glows orange
and the current “null” position of the NOTCH filter
will appear in the NOTCH indicator on the display.
The
[
SELECT
]
knob functions as the Notch adjust-
ment knob.
2. Rotate the
[
SELECT
]
knob to adjust the “null” posi-
tion of the Notch filter.
ADVICE:
The frequency display will show the Notch frequency
for 3 seconds whenever the
[
SELECT
]
knob is turned.
3. Press the
[
CLEAR
]
button to move the “null” position
to center.
4. To cancel the NOTCH filter, press the
[
NOTCH
]
but-
ton (or
[
SELECT
]
knob) momentarily. The graphic
disappears from the NOTCH indicator on the display,
confirming that the NOTCH filter is no longer opera-
tion.
ADVICE:
Alternate presses of the
[
NOTCH
]
button or the
[
SE-
LECT
]
knob, will switch the NOTCH filter between
on or off.
ADVICE:
The IF NOTCH Filter selection will be memorized
independently on each VFO stack of VFO-A and VFO-
B.
When the optional DMU-2000 Data Management Unit
is connected, the effect of the IF NOTCH filter may be
observed on the Audio Scope (on the “Oscilloscope”
page). The Notch will be observed as a “dip” in the
noise platform observed. What’s more, the “Waterfall”
display may be used to observe the effect of the IF
NOTCH filter, which will appear as a white area in the
colored background area.
