Simple band scope
The Band Scope function allows you to visually check
the location and strength of signals around a specified
frequency.
The IC-7410’s Band Scope function can be used in
any operating mode and any frequency band.
INDICATOR
DESCRIPTION
Sweep icon
While the band scope is sweeping, “
” is displayed; while stopped, “
” is displayed.
Received audio is not heard from the speaker while the band scope is sweeping.
Band scope
display
Displays the signal location and strength in relation to the center (displayed) frequency. Signal strength is
relative to the S-meter level, S1 to S9, with each vertical dot in the band scope indicator equal to one seg-
ment of the S-meter. Signal activity is measured ±30 steps from the center frequency, with each step equal
to the selected sweep step.
Frequency
display mark
After a sweep, displays the relative position of the reference frequency. When the reference frequency is
outside of the sweep range, “ ” or “ ” blinks. After changing the frequency, hold down [F-3] for 1 second to
automatically return to the center frequency.
Sweep step
display
Displays the selected sweep step. 0.5, 1, 2, 5, 10, 20 and 25 kHz are selectable. Each dot of the band scope
display is approximately equal to the selected sweep step.
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 [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 sweep-
ing.
• During a sweep, “
” is displayed and received sig-
nals cannot be heard.
• 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 [DIAL] to find a signal that you wish to com-
municate with. If you find the signal, communicate
in the normal way.
• If you want to return to the frequency you were using
before rotating [DIAL], hold down [F-3] for 1 second.
• If the selected frequency is set outside of the sweeped
range, “ ” or “ ” blinks.
y
If you want to update the band conditions while re-
ceiving, repeat steps
