RECEIVE AND TRANSMIT

D
Two optional filters can be installed in the IC-
706MKIIG.
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.
Consult the table below to select a filter most suitable
for your operating needs.
Narrow filters for AM/FM modes are standard.
After you install a filter (see p. 60 for installation), you
must specify the installed filter in initial set mode (item
19 "OPT. FIL 1" or item 20 "OPT. FIL 2"; see p. 51).
