Marker Centering (Fixed Mode)

The scope range can be shifted temporarily with the display
frequency span maintained such that the marker of the selected
amateur band is displayed near the center (within one grid to the
left or right from the center).
Press F4 [MKR.CTR].
• If F4 [MKR.CTR] is not displayed, press F [MORE] to display
F4 [MKR.CTR].
The scope range is shifted with the frequency span maintained.
.
Changes in the lower and upper frequency limits due to
●
the marker centering operation are temporary, and does
not alter the preconfigured lower and upper frequency
limits of the scope band in question.
Notification on Exceeding the Lower or Upper Limit
(Fixed Mode)
If the marker frequency falls outside the display range of the
bandscope when a frequency marker is displayed on the
bandscope in the Fixed mode, a display appears to inform the user
that the marker has moved out of the bandscope range.
A " " icon appears at the left edge of the bandscope screen if the
marker frequency value is smaller than the lower frequency limit,
and a " " appears at the right edge if the marker frequency value
is larger than the upper frequency limit.
The markers indicating that the lower or upper limit is exceeded
are color coded as follows.
White: RX frequency
Red: TX frequency

Selecting Relative or Absolute Frequency Display for
the Grid (Center Mode)
During carrier point center display in the Center mode, the mode
of frequency scale display at the bottom of the bandscope can be
switched to one of the options available.
Configure in Menu [8-06] "Frequency Scale (Center
Mode)"
Relative Frequency (default)/ Absolute
Setting Value
Frequency
Relative Frequency: The frequency scale display at the
bottom of the scope area represents the relative frequency from
the center of the scope.
Absolute Frequency: The frequency scale display at the
bottom of the scope area represents the absolute frequency.

Displaying Tuning Assist Line (SSB Only)

A tuning auxiliary line (yellow) referred to as assist line can be
displayed parallel to the RX frequency marker during operation in
the SSB mode.
Set the assist line at 400 Hz to 500 Hz (near the peak of a typical
frequency spectrum of a human voice) for voice communication
and at the frequency of the subcarrier for data communication.
Zero-in can be performed easily by adjusting the assist line to the
strongest point of the spectrum on the waterfall.
Configure in Menu [8-05] "Tuning Assist Line (SSB
Mode)"
Off (default)/ 300/ 400/ 500/ 600/ 700/ 800/
Setting Value

This function works in the Center mode only when Menu

[8-03] "Waterfall when Tuning (Center Mode)" is
configured to "Straight".
The tuning assist line is displayed on the upper side with
●
respect to the carrier point in the case of USB and on the
lower side in the case of LSB.

Configuring the Gradation of the Waterfall

The amount of color change with respect to the signal strength in
the waterfall display can be configured from a scale of 1 to 10.
Configuring a larger value increases the amount of color change
making it easier to find weak signals. Configuring a smaller value
reduces the amount of color change making it easier to observe
strong signals.
Configure in Menu [8-04] "Waterfall Gradation
Level"
Setting Value 1 to 7 (default) to 10 (1 step)
