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.
