Operation Manual

VX-8DR/DE 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-

8DR/DE is in the “Mono” band operation.

Three basic operating modes for the Spectrum Analyzer are available:

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

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: This mode is activated similar to a “CONTINUOUS” mode. However, the

transceiver outputs the audio of the center frequency (



) from a speaker

when the Spectrum Analyzer is activated between 30 ~ 580 MHz (except

FM Broadcast Band).

SETTING UP THE SPECTRUM ANALYZER MODE:

1. Press and hold the key for one second to enter the Set Mode.

2. Rotate the DIAL knob to select Set Mode Item 91: SPEC-

ANALYZER.

3. Press the key briefly to enable adjustment of this Set

Mode Item.

4. Rotate the DIAL knob to select the desired Spectrum Ana-

lyzer mode (see above).

5. Press the PTT switch momentarily to save the new setting

and exit to normal operation.

TO ACTIVATE THE SPECTRUM ANALYZER:

1. Set the radio to the VFO mode on the “A-Band” in the “Mono” band mode.

2. Press the key, then press the key to activate the

Spectrum Analyzer.

3. When the Spectrum Analyzer is activated, press the or

key to change the visible bandwidth. Available selec-

tions are ±5, ±9, ±16, ±24, and ±50 channels (default: ±16 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.

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

key.
