CHANGING THE DISPLAYED FREQUENCY SPAN

(CENTER MODE)

You can change the displayed frequency span (the width

of the lower limit and upper limit frequencies on the

Bandscope screen) while the bandscope is displayed in

Center mode.
1 Press [SPAN] (F4) to change the frequency display

span.

• Each key press cycles the frequency span through 5 kHz >

10 kHz > 20 kHz > 50 kHz > 100 kHz > 200 kHz > 500 kHz

> 5 kHz.

• Each long press of [SPAN] (F4) cycles the selection in the

reversed sequence.

• The selected frequency span appears as "SPAN 50 kHz"

on the toolbar of the Bandscope screen.

• The default is “50 kHz”.

• If [SPAN] (F3) is unavailable in the key guide, press

[MORE] (F1).

SWITCHING THE MARKER OFFSET FREQUENCY (SSB

ONLY)

The marker display location while the bandscope for

SSB mode is displayed can be switched to the carrier

point which is the same as the frequency display or to a

frequency offset from the carrier point.
1 Select Group No. 8, "Bandscope", from the Menu

screen.

2 Access Menu 03, "Marker Offset Frequency (SSB

Mode)".

3 Press [SELECT] (F4) to allow editing of the parameter

box.

4 Press [-] (F4) or [+] (F5) to select "Off (Carrier Point)"

or the offset frequency.

The default is "500 [Hz]" (near the peak of the frequency

spectra for the typical human vocal). While the bandscope

and Waterfall are displayed, placing a marker near the

frequency having the strongest level can easily zero-in even

in SSB mode. The peak of the frequency spectra may vary

or may not be distinguished due to the audio quality of the

transmitting station.

5 Press [

] (F1).

6 Press [MENU] to exit.

Note:

◆ If the bandscope is in Center mode, the frequency which is added

by the frequency configured in Menu 8-03 to the carrier point

frequency will be the center frequency for USB mode, and the

frequency which is subtracted by the frequency configured in Menu

8-03 from the carrier point frequency will be the center frequency

for LSB mode. The lower limit frequency and upper limit frequency

appear following the center frequency.

◆ If the bandscope is in Fixed mode, the frequency which is added

by the frequency configured in Menu 8-03 to the carrier point

frequency will be the marker frequency for USB mode, and the

frequency which is subtracted by the frequency configured in Menu

8-03 from the carrier point frequency will be the marker frequency

for LSB mode.
