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.

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.

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.

a selected frequency, in either the VFO or memory
modes.
