Band Scope
•
Allows operators to visually check signal condition around a specified frequency
in any operating mode and frequency band.
•
–
Sweep indicator
Gives visual indication of scope status. Received audio is not emitted
from the speaker while the band scope is “sweeping.”
–
Band scope indicator
Visually represents a relative strength of signals and their
location 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 segment of the S-meter. Signal activity is measured ±30 steps from the
center frequency with each step equal to the selected sweep step.
–
Frequency indicator mark
After a sweep, indicates the relative position of the selected
frequency.
•
When the selected frequency is outside of the sweep range, indicator flashes. After changing the
frequency, push [F3] to automatically return to the center frequency.
–
Sweep step
Indicates the selected sweep step. 0.5, 1, 2, 5, 10, 20 and 25 kHz are
selectable. Each dot of the band scope indication is approx. equal to the selected sweep
step.
