Selecting the

digital IF ﬁlter

The IC-R8600 has 3 digital IF ﬁlter passband widths for

each receive mode.

Touch the ﬁlter icon several times to select FIL 1

(wide), FIL 2 (mid) or FIL 3 (narrow).

Each touch changes the ﬁlter.

Adjusting the passband width

Touch the filter icon for 1 second.

2. Touch [BW].

•

Selects the passband width mode.

You cannot change the passband width in the FM,

WFM or DIGITAL modes.

3. Rotate

MAIN DIAL

to adjust the passband width.

When you change the passband width, the Twin PBT

setting is reset to the center position.

In the SSB or CW mode, you can change the filter

shape by touching [SHARP] or [SOFT].

See "Selecting the ﬁlter shape" to the right.

To close the FILTER screen, push

EXIT

several

times.

Selecting the

ﬁlter shape

In the SSB or CW mode, you can independently

set the DSP ﬁlter shape to soft or sharp for each

operating mode.

SHARP

This selection is to emphasize the passband width

of the ﬁlter. The ﬁlter has an almost ideal shape

factor. Signals out of the passband are extremely

ﬁltered out and it gives you better audio quality.

SOFT

The ﬁlter shoulders are roundly formed as in analog

ﬁlters. This decreases noise components in the

high and low frequencies of the ﬁlter passband and

increases the S/N ratio of the target signal. These

characteristics play an effective role in picking up

very weak signals. The ﬁlter shape is kept, and the

sharpness of the bandpass is excellent.
