BandScopefunction
Use the Band Scope function to visually search a spec-
ified frequency range around the displayed frequency.
You can use this function to search for a signal, and see
the received signal strength level.
The Band Scope function has two sweep types, Single
sweep and Continuous sweep:
• A Single sweep searches the specied frequency
range only once.
• A Continuous sweep repeatedly searches the speci-
fied frequency range.
The transceiver sweeps in the following ranges cen-
tered on the displayed frequency.
• The sweep steps may differ, depending on the tuning step.
Single watch mode: ±38 × Tuning step
Dualwatch mode: ±18 × Tuning step
(‘ ±38 ’ and ‘ ±18 ’ are fixed.)
For example in the Dualwatch mode, if the display fre-
quency is 146.010 MHz and its tuning step is 20 kHz,
the sweep range is between 145.650 MHz (lower fre-
quency) and 146.370 MHz (higher frequency). (146.010
MHz±0.36 MHz) See the calculation below.
+18 × 20 kHz = +360 kHz (0.36 MHz)
–18 × 20 kHz = –360 kHz (–0.36 MHz)
Upper frequency: 146.370 MHz
(146.010 MHz + 0.36 MHz)
Lower frequency: 145.650 MHz
(146.010 MHz – 0.36 MHz)
Example: A strong signal is received on 146.030 MHz.

Aboutthesweepsteps:
The specified tuning step is used during a sweep.
If the tuning step is set too wide, the signals in the
sweep range may not be displayed (they may be
skipped), even if they are strong signals.
Thus we recommend that you set the tuning step to
20 kHz or less to use the Band Scope function.
See page 2-6 for tuning step selection details.
• For Single watch operation, you can hear the dis-
played frequency’s audio during a sweep.
• The audio output during a sweep can be turned
OFF in the MENU screen.

D Sweepoperation
Example: Continuous sweeps centered on 146.010 MHz
Rotate [DIAL] to set 146.010 MHz. q
Touch the Function group icon one or more times. w
• Selects the F-3 menu.
Touch [SCOPE]. e
• Opens the Band scope setting window.
Touch “Continuous Sweep.” r
• Returns to the frequency display and starts continuous
sweeping.
• While sweeping, touch [≈] to stop the sweeping. Touch
again to start single sweep.
• When the sweeping stops, touch [≈] for 1 second to
restart continuous sweeping.
While continuous
sweeping
When the sweeping stops, rotate [DIAL] to move the t
sweep marker to a detected signal.
• You can hear the signal audio.
When the sweeping stops,
move the sweep marker
to a detected signal to
hear the signal audio.
To turn OFF the Band Scope function, touch y
[SCOPE].
• Opens the Band scope setting window.
Touch “Scope OFF.” u
In the Band scope setting
window, touch “Center
Recall” to set the sweep
marker to the center fre-
quency.
