VX-8R OPERATING MANUAL96
The Spectrum Analyzer allows viewing operating activity on channels above or below the
current operating channel in the VFO mode.
The display indicates the relative signal strength on channels immediately adjacent to the
current operating frequency.
The Spectrum Analyzer feature can be activated only on the “A-Band” while the VX-8R
is in the “Mono” band operation.
Three basic operating modes for the Spectrum Analyzer are available:
1Time1Time

channel steps with the amateur band you are using.
4. To turn the Spectrum Analyzer off and operate on the center (displayed) channel,
press the key to stop the sweep, if needed, then press the key followed by
