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.

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.
