This feature is convenient when you want to monitor an entire amateur band.
The starting point, located at the left edge of the screen, can be set via the Menu. Even if the screen span
(bandwidth) is changed, the start frequency will
not be changed. By watching the screen, you can move your
operation to frequencies where interesting activity appears on the display. Just as with the CTR mode, it is
possible to toggle the Main (VFO-A) or Sub (VFO-B) VFOs. It is also possible to utilize a dual display, with the
Main (VFO-A) VFO in the upper position, and the Sub (VFO-B) VFO below.
1. By pressing the [ 7/18

CTR/FIX

sible to switch between the CTR mode and the
FIX mode. Select the CTR mode at this time.
2. Press the [ 2/3.5
](
SPAN
) key to set the desired
value for the Span (bandwidth). By pressing the

lows.

tral display.

Press the [ MNU
] key momentarily to enter the
Menu mode. Select the item which you want to
change by rotating the Main dial (in this case, the
items will be in the range from “
SCOPE 112 MAIN
FIX 1.8 MHz ” to “ SCOPE 133 SUB FIX 50MHz ”).
Now you may change the setting by rotating the
Sub dial.
When the change(s) are completed, press and hold
in the [
MNU
] key for 2 seconds to save the change.
If you do not want to save the change(s), press
the [
MNU
] key momentarily. The radio will go back
to its previous condition/situation.
There are many setup items in the Menu, and
they are grouped; the group name is displayed at
the top left area of the list screen. It will generally
be more convenient for you if you initially select
the group, by rotating the Main Dial, and then
select the item you want to work on.

Advice :In the case of the Contest version, the [ RX
]
switch to the left of the [ CLAR/VFO-B
] knob will, when
pushed, cause both the VFO itself and the Spec-
trum Scope display to change to VFO-B. Addition-
ally, when the optional
RXU-9000 Dual Receive Unit
is installed, you may use the [ 5/10
](
DUAL
) key to
enable Dual-band Spectrum Scope operation, just
like on the MP version.
6. You may clear the “ Average indication ” or “ Peak
indication ” which was set by TRACE MODE (See
page 17) by pressing the [ F7
](
REFRESH
) key.
7. Just as in the CTR mode, you can use the Marker.
Please see page 14 for information on using the
