The spectrum scope enables you to display the
activity on the selected band, as well as the relative
strengths of various signals.
The transceiver has two spectrum scope modes, the
Center mode and the Fixed mode.
You can also turn the Waterfall display ON or OFF.
In addition, you can select the Mini scope to display it
in a smaller size on the screen.
