This page displays the Spectrum Scope which is con-
venient for monitoring band activity.
The entire screen will become the spectrum display,
and you can see both strong and weak signals clearly
and easily. Not only the Main (VFO-A) is shown, but
the spectrum of the Sub (VFO-B) side can be also
switched in and displayed simultaneously.
Besides simultaneous display of the Main (VFO-A)
and Sub (VFO-B) spectra, the LBWS function allow
you to realize very high-speed signal detection over
a limited band segment. The CTR mode let you moni-
tor close by your current frequency (your frequency
is located at the center of the screen), and the FIX
mode can also be engaged, whereby the left edge
frequency is fixed. These features have been care-
fully considered for their utility in actual Amateur Ra-
dio operation.
If the Spectrum Scope is not currently displayed, press
the [
DISP

as needed to bring up the Spectrum Scope display
screen.
