VX-7R OPERATING MANUAL 63

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 only be activated while the VX-7R is operat-

ing in the Mono band mode.

Two basic operating modes for Spectrum Analyzer are available:

1: In this mode, the transceiver sweeps the current band once.

CONTINUOUSCONTINUOUS

CONTINUOUS: In this mode, the transceiver sweeps the current band repeatedly until

pressing the key, or the Spectrum Analyzer is turned off.

lections are ±5, ±8, ±14, ±29, and ±60 channels (default: ±5 channels). The visible

bandwidth, however, depends on the selected channel step size, so match the default

channel steps with the amateur band you are using.
