ABOUT THE SPECTRUM SCOPE
SPECTRUM SCOPE
This page displays the Spectrum Scope, which is conve-
nient for monitoring band activity.
The entire screen will become a spectrum display, and
Both strong and weak signals from the Main (VFO-A)
band receiver are clearly shown.
The LBWS (Limited Band Width Sweep) function pro-
vides very high-speed signal detection over a limited band
segment.
The CTR mode (your frequency is located at the center of
the screen), permits monitoring signals close to your cur-
rent frequency.
The FIX mode (the left band edge frequency is fixed) can
also be engaged. These features have been carefully con-
sidered for their utility in actual Amateur Radio opera-
tion.
If the “Spectrum Scope” screen does not initially appear,
press the

erations to “Page Select” mode. Then press the
