QUICK REFERENCE GUIDE
f. Filter:
One optional filter can be installed in the IC-703.
Narrow filters help reject interference from adjacent
signals and obtain good selectivity.
Wide filters provide improved audio for SSB opera-
tion when no interfering signals are present.
Narrow filters for AM/FM modes are standard.
FILTER PRESETTING:
After you install a filter (see p. 87 for installation), you
must specify the installed filter in initial set mode (item
“22 OPT. FIL” ; see p. 79).
