5 FUNCTIONS FOR RECEIVE ■ IF filter selection The transceiver has 3 passband width IF filters for each mode. The filter selection is automatically memorized in each mode. The PBT shift frequencies are automatically memorized in each filter. D IF filter selection q Select the desired mode. w P ush [FILTER] one or more times to select IF filter 1, 2 or 3. • T he selected passband width and filter number is dis- played on the LCD. D Filter passband width setting (Mode: SSB/CW/RTTY/AM) q H old down [FILTER] for 1 second to display the "FIL" screen (Filter) to set the filter passband width. w Select either the SSB, CW, RTTY or AM mode. • Passband widths for FM and DV modes are fixed and cannot be set. e P ush [FILTER] one or more times to select IF filter 1, 2 or 3. r P ush [BW](F-1), then rotate [MAIN DIAL] to adjust the desired passband width. Then push [BW](F-1) to set it. • While holding down [BW](F-1), rotating [MAIN DIAL] also adjusts the passband width. After adjustment, release [BW](F-1) to set it. • H old down [F-3] for 1 second to reset to the default setting, if desired. t Repeat steps w to r if desired. y P ush [MENU] to save, and exit the "FIL" screen.

The filter selection is automatically memorized in
each mode.
The PBT shift frequencies are automatically memo-
rized in each filter.
D
IF filter selection
q
Select the desired mode.
w
Push [FILTER] one or more times to select IF filter
1, 2 or 3.
• The selected passband width and filter number is dis
-
played on the LCD.
D
Filter passband width setting
(Mode: SSB/CW/RTTY/AM)
q
Hold down [FILTER] for 1 second to display the “FIL”
screen (Filter) to set the filter passband width.
w
Select either the SSB, CW, RTTY or AM mode.
• Passband widths for FM and DV modes are fixed and
cannot be set.
e
Push [FILTER] one or more times to select IF filter
1, 2 or 3.
r
Push [BW](F-1), then rotate [MAIN DIAL] to adjust
the desired passband width.
Then push
[BW](F-1)
to
set it.
• While holding down [BW](F-1), rotating [MAIN DIAL]
also adjusts the passband width. After adjustment, re-
lease [BW](F-1) to set it.
• Hold down [F-3] for 1 second to reset to the default set
-
ting, if desired.
t
Repeat steps
w
to
r
if desired.
y
