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:
1Time
1Time 1Time 1Time 1Time : In this mode, the transceiver sweeps the current band once.
CONTINUOUS CONTINUOUS CONTINUOUS CONTINUOUS CONTINUOUS : In this mode, the transceiver sweeps the current band repeatedly until the
key is pressed, or the Spectrum Analyzer is turned off.
Full Time Full Time Full Time Full Time Full Time : This mode is activated similar to a “CONTINUOUS CONTINUOUS CONTINUOUS CONTINUOUS CONTINUOUS ” mode. However, the
transceiver outputs the audio of the center frequency (T) from a speaker
when the Spectrum Analyzer is activated between 30 ~ 580 MHz (except
FM Broadcast Band).
