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.
CONTINUOUS
: In this mode, the transceiver sweeps the current band repeatedly until
pressing the
key, or the Spectrum Analyzer is turned off.
Setting up the Spectrum Analyzer mode:

Press the
key, then press the
key to enter the Set mode.
