Band Scope function
The Band Scope function allows you to visually check a spec-
ified frequency range around the center frequency.
The receive audio during sweeping can be muted in
SOUNDS menu. See page 48 for details.
About the sweep steps:
The specified tuning step (in VFO mode) or programmed
tuning step (in memory mode) is used during sweep.
If the tuning step is set to wide, the present signal may not
be displayed (may be skipped), even that is strong signal.
Thus we recommend to set the tuning step to the 20 kHz
or less to use the Band Scope function.
See page 23 for the Tuning step selection details.
