Selecting the IF lter
SSB, CW, RTTY, PSK, and AM modes
The IC-7760 has 3 IF lter passband widths for
each mode, and you can select them on the FILTER
screen.
You can set the IF lter to wide (FIL 1), mid (FIL 2), or
narrow (FIL 3).
1. Select the operating mode. (Example: CW)
2. Touch the IF Filter indicator for 1 second.
• Opens the FILTER screen.
3. Touch the IF Filter indicator several times to select
FIL 1 (wide), FIL 2 (mid), or FIL 3 (narrow).
4. Touch [BW].
• Selects the passband width mode.

Selecting the IF lter shape
SSB and CW modes
You can set the IF lter shape for each mode.
1. Select the operating mode. (Example: CW)
2. Touch the filter icon for 1 second.
• Opens the FILTER screen.
3. Touch [SHARP] or [SOFT].
L Touching [SHAPE SET] opens the FILTER SHAPE
SET screen.
4. To close the FILTER screen, push
EXIT
.
• SHARP
This selection is to emphasize the passband width of the
lter. The lter has an almost ideal shape factor. Signals
that are out of the passband are extremely ltered out,
and it gives you better audio quality.
• SOFT
The lter shoulders are roundly formed as in analog
lters. This decreases noise components in the high and
low frequencies of the lter passband, and increases the
S/N of the target signal. These characteristics play an
eective role in picking up very weak signals. The shape
factor is retained, and the sharpness of the bandpass is
excellent.
5. Rotate
MAIN
DIAL
to select the passband width.
L You cannot change the passband width in the FM or
FM-D mode.
L When you change the passband width, the Digital
Twin PBT setting value is reset to the center position.
L “BPF” is displayed when a band width is set to
500 Hz or less in the SSB, CW, RTTY, or PSK mode.
6. To close the FILTER screen, push
EXIT
.
TIP: When you set the IF lter to FIL2 or FIL3 in the
FM mode, the transceiver will transmit in the FM
narrow mode.
You can reset to the default settings
by touching this key for 1 second.
