Band Scope Operation
The Band Scope allows viewing of operating activity on channels above or below the
current operating channel in the VFO mode.
The display will indicate the relative signal strengths of signals on channels immediately
adjacent to the current operating frequency. A convenient “Channel marker” can be used to
zero in on one of the stations displayed; when you turn off the Band Scope, the
VR-5000
will be set to the frequency set by the Channel Marker.
To activate the Band Scope

(

3. When the Band Scope is activated, press the [ M/S
(

the Channel Marker.
This allows the Channel Marker to be moved anywhere within the programmed sweep
