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
) key, it is possible
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
[
2/3.5
](
SPAN
) key, the span will change as fol-
lows.
25 kHz 50 kHz 100 kHz 250 kHz
500 kHz 1000 kHz 2500 kHz 25 kHz ......
3. Press the [ 3/5
](
ATT
) key to set the desired at-
tenuation value. By pressing the [ 3/5
](
ATT
) key,
the attenuation will change as follows.
0 dB 10 dB 20 dB 0 dB ......
4. Press the [ 4/7
](
A/B
) key to toggle between the
Main (VFO-A) and Sub (VFO-B) VFOs.
5. Press the [ 5/10
](
DUAL
) key to engage dual spec-
tral display.
The Main VFO will appear in the upper display
field, and the Sub VFO will appear in the lower.
When you rotate the Main Tuning knob for Main
(VFO-A) or
CLAR/VFO-B knob for Sub (VFO-
B), the yellow arrow “ ” will move to follow your
receive frequency.
If the receive frequency is outside of the screen,
the position of the operating frequency will be
“shown” in the lower area of the display as “
<< ”
“ >> ”, and “
RCV Freq is out of range
” will also be
displayed.
6. Just as in the CTR mode, you can use the Marker.
Please see page 14 for information on using the
marker.
Advice : In either CTR or FIX mode, the current op-
erating frequency will be indicated on the screen by
the yellow arrow “

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 “107:
MAIN FIX 1.8
MHz ” to “128: 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
Spectrum Scope display to change to VFO-B. Addi-
tionally, 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.
