frequency.
The IC-9100's Band Scope function can be used in
any operating mode and any frequency band.

Sweep step
Displays the selected sweep step. 0.5, 1, 2, 5, 10, 20 and 25 kHz are selectable. Each dot of the band scope

The band scope measures receive signal location
and strength over a specified range on either side of
a selected frequency, in either the VFO or memory
modes.
q Rotate [MAIN DIAL] to select a frequency.
w Push [MENU] to display the "M1" screen (Menu 1),
then push [SCP](F-5) to display the "SCP" screen
(Band Scope).
• Automatically starts sweeping with the previously se-
lected sweeping step.
• During a sweep, received signals cannot be heard.
e Push [F-5] one or more times to select the desired
sweep step.
•
0.5, 1, 2, 5, 10, 20 and 25 kHz are selectable.
r Push [F-1] to start sweeping, then automatically
stop after sweeping.
• Hold down [F-1] for 1 second to start continuous sweep-
ing. In this case, push [F-1] again to stop the sweeping.

• If there is a lot of signal noise, turn OFF the Preamplifier
to reduce the signal input level, and turn ON the Attenu-
ator to improve the readability of the band scope.
t Rotate [MAIN DIAL] to find a signal that you wish to
communicate with. If you find the signal, communi-
cate in the normal way.
• If you want to return to the frequency you were using
before rotating [MAIN DIAL], hold down [F-3] for 1 sec-
ond.
• If the selected frequency is set outside of the sweeped
range, " " or " " blinks.
