PECTRUM
This page displays the Spectrum Scope which is conve-
nient for monitoring band activity.
The entire screen will become the spectrum display, and
you can see both strong and weak signals clearly and eas-
ily on the Main (VFO-A) band.
Furthermore, the LBWS function allow you to realize
very high-speed signal detection over a limited band seg-
ment. The CTR mode let you monitor close by your cur-
rent 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 carefully considered for their utility in actual
Amateur Radio operation.
