5 FUNCTIONS FOR RECEIVE D 1st IF filter selection (Mode: SSB/CW/RTTY/AM) The IC-9100 has a 15 kHz filter passband width at the 1st IF frequency. The 1st IF filters reduce interference from strong nearby signals. If the optional FL-430 1st if filter (6 khz) is installed, a 6 kHz filter width can be used. Or, if the FL-431 1st if filter (3 khz) is installed, a 3 kHz filter width can be used. • T he filter passband width can be selected on only the HF/50 MHz band frequency. q H old down [FILTER] for 1 second to display the "FIL" screen (Filter). w Select SSB, CW, RTTY or AM mode. • T he passband widths for FM and DV modes are fixed, and have no options. e H old down [F-5] for 1 second to select the desired filter width from 15 kHz, 6 kHz and 3 kHz. • Hold down [F-3] for 1 second to reset to the default filter setting, if desired. (The filter passband width setting is also reset to the default setting.) r P ush [MENU] to save, and exit the "FIL" screen. D IF (DSP) filter shape (Mode: SSB/CW) A soft or sharp type of DSP filter shape for both SSB and CW can be independently selected. q H old down [FILTER] for 1 second to display the "FIL" screen (Filter). w Select the SSB or CW mode. e P ush [F-5] once or twice to select either the soft or sharp filter shape. r P ush [MENU] to save, and exit the "FIL" screen (Fil- ter).

1st IF filter selection
(Mode: SSB/CW/RTTY/AM)
The IC-9100 has a 15 kHz filter passband width at the
1st IF frequency. The 1st IF filters reduce interference
from strong nearby signals.
If the optional FL-430
1
ST
IF
FILTER
(6

is installed,
a 6 kHz filter width can be used. Or, if the FL-431
1
ST
IF
FILTER
(3
k
H
z
)
is installed, a 3 kHz filter width can be
used.
• The filter passband width can be selected on only the
HF/50 MHz band frequency.
q
Hold down [FILTER] for 1 second to display the “FIL”
screen (Filter).
w
Select SSB, CW, RTTY or AM mode.
• The passband widths for FM and DV modes are fixed,
and have no options.
e
Hold down [F-5] for 1 second to select the desired
filter width from 15 kHz
,
6 kHz and 3 kHz.
• Hold down [F-3] for 1 second to reset to the default filter
setting, if desired.
(The filter passband width setting is
also reset to the default setting.)
r
Push [MENU] to save, and exit the “FIL” screen.
D
IF (DSP) filter shape
(Mode: SSB/CW
)
A soft or sharp type of DSP filter shape for both SSB
and CW can be independently selected.
q
Hold down [FILTER] for 1 second to display the “FIL”
screen (Filter).
w
Select the SSB or CW mode.
e
Push [F-5]
once or twice
to select either the soft or
sharp filter shape.
r
Push [MENU] to save, and exit the “FIL” screen (Fil-
ter).
