The transceiver has 3 passband width IF filters for
each mode.
For SSB, CW and PSK modes, the passband width
can be set within 50 to 3600 Hz in 50 or 100 Hz steps.
A total of 41 passband widths are available.
For RTTY mode, the passband width can be set within
50 to 2700 Hz in 50 or 100 Hz steps. A total of 32
passband widths are available.
For AM mode, the passband width can be set within
200 Hz to 10 kHz in 200 Hz steps. A total of 50 pass-
band widths are available.
For FM mode, the passband width is fixed and 3 pass-
band widths are available.
q Select the desired mode.
w Push [FILTER] several times to select the IF filter 1,
2 or 3.
• The selected passband width and filter number is dis-

q Hold down [FILTER] for 1 second to enter filter set
screen.
w Select any mode except FM.
• Passband widths for FM modes are fixed, and cannot be
adjusted.
e Push [FILTER] several times to select the desired
IF filter.
r Push [F-1•BW], then rotate the main dial to adjust
the desired passband width. Then push [F-1•BW]
again.
• While holding down [F-1•BW], rotating the main dial also
adjusts the passband width. After adjustment, release
[F-1•BW] to set.
t If desired, repeat steps w to r.
• Hold down [F-4•DEF] for 1 second to select the default
value.
y Push [EXIT/SET] to exit filter set screen.
