10 SCAN SCAN 10 Scan is a function that searches for signals by automatically altering the frequency. This transceiver makes use of the following scan methods to search for signals. Scan Type Program Scan Normal Scan VFO Scan Scan Using Memory Channels All-Channel Scan Group Scan Quick Memory Scan Purpose Performs scan in the frequency ranges that are registered in the memory channels for specific band segments (P0 to P9). Performs scan on the entire RX frequency band. When Program Scan is set to OFF for all the memory channels for specific band segments, Program Scan switches automatically to VFO Scan. However, when VFO Scan is selected, VFO Scan is performed even when not all channels are set to OFF. Scans all Memory channels from 00 to 99, P0 to P9, and E0 to E9. Scans the grouped memory channels. Scans the Quick Memory channels. Program Scan Program Scan performs scan between the range specified by the start and end frequencies which are registered in the each of memory channels for specific band segments (P0 to P9). • Configure the frequency range for Program Scan in the memory channels for specific band segments (P0 to P9). Up to 10 frequency ranges that are transmitted by specific stations can be preconfigured. Enabling standby in a nearby frequency makes it easy to perform tuning to a specific station when the station starts communication in the preconfigured frequency range. ● Program Scan performs scan between the start and end frequencies of a memory channel for specific band segments and moves to the next channel after scanning of the specified frequency range has ended. ● While scanning is in progress, turning the Tuning or [MULTI/CH] control allows the frequency to be changed quickly. The same operation can also be used to change the scanning direction. ● Scanning is performed in the ascending order from low to high frequency. Configuring the end frequency to a value smaller than the start frequency by turning the Tuning or [MULTI/CH] control reverses the scanning direction (high to low frequency). ● Scanning is performed based on the step frequency of the Tuning control when in the SSB, CW, FSK and PSK modes, while it is based on the step frequency of the [MULTI/CH] control when in the FM mode, and fixed at 100 Hz in the AM mode. ● Scanning stops when signals are received while performing Program Scan (VFO Scan) in the FM mode or during Memory Scan (All-channel Scan or Group Scan) or Quick Memory Scan regardless of the operating mode. For more information on the conditions to resume scanning, please refer to "Configuring the Conditions for Resuming Scan" (10-4). ● During standby for the CTCSS tone in the FM mode, scan stops only when there is a matching CTCSS tone. ● When the [SQL] control is turned to the right to a level that far exceeds the squelch threshold while in the FM mode, scanning may not stop even at a channel where a signal is present. Configure the squelch level to a point that is near the squelch threshold. Starting the Program Scan (VFO Scan) 1 Press [M/V] to switch to VFO mode. 2 Press F5 [SCAN] to start program scan (VFO scan). • Pressing F5 [SCAN] again or [ESC] ends the Program Scan (VFO Scan). .. Configuring the Program Scan (VFO Scan) Frequency Range Scanning can be configured to the frequency range specified in the memory channels for specific band segments (Program Scan) or the entire RX frequency band (VFO Scan). To perform Program Scan, register the memory channels for specific band segments. 1 Press [M/V] to switch to VFO mode. 2 Press and hold F5 [SCAN] to display the VFO/ Program Scan configuration screen. 3 Press F5 [VFO/PROG] to display the Program Scan segment screen. 4 Press F2 [ ]/ F3 [ ] to select a memory channel for specific band segments. 5 Press F4 [ ] to select whether to scan the memory channel for specific band segments. • Pressing F4 [ ] each time selects (performs scan) or deselects (does not perform scan) the checkbox. • When performing VFO Scan, deselect the checkboxes for all the memory channels for specific band segments or press [VFO/PRG] to switch the display to "VFO SCAN". • Pressing F6 [SEL.ALL] selects the checkboxes for all the memory channels for specific band segments. • Pressing F7 [CLR.ALL] deselects the checkboxes for all the memory channels for specific band segments. 6 Press [ESC] to end the process. 10-1

Scan is a function that searches for signals by automatically
altering the frequency. This transceiver makes use of the following
scan methods to search for signals.
Scan Type
Purpose
Normal Scan
Program Scan
Performs scan in the frequency
ranges that are registered in the
memory channels for specific band
segments (P0 to P9).
VFO Scan
Performs scan on the entire RX
frequency band. When Program
Scan is set to OFF for all the
memory channels for specific band
segments, Program Scan switches
automatically to VFO Scan.
However, when VFO Scan is
selected, VFO Scan is performed
even when not all channels are set
to OFF.
Scan Using
Memory
Channels
All-Channel
Scan
Scans all Memory channels from 00
to 99, P0 to P9, and E0 to E9.
Group Scan
Scans the grouped memory
channels.
Quick Memory
Scan
Scans the Quick Memory channels.
Program Scan
Program Scan performs scan between the range specified by the
start and end frequencies which are registered in the each of
memory channels for specific band segments (P0 to P9).
•
Configure the frequency range for Program Scan in the memory
channels for specific band segments (P0 to P9). Up to 10
frequency ranges that are transmitted by specific stations can
be preconfigured. Enabling standby in a nearby frequency
makes it easy to perform tuning to a specific station when the
station starts communication in the preconfigured frequency
range.
●
Program Scan performs scan between the start and end
frequencies of a memory channel for specific band
segments and moves to the next channel after scanning
of the specified frequency range has ended.
●
While scanning is in progress, turning the
Tuning
or
[MULTI/CH]
control allows the frequency to be changed
quickly. The same operation can also be used to change
the scanning direction.
●
Scanning is performed in the ascending order from low
to high frequency. Configuring the end frequency to a
value smaller than the start frequency by turning the
Tuning
or
[MULTI/CH]
control reverses the scanning
direction (high to low frequency).
●
Scanning is performed based on the step frequency of
the
Tuning
control when in the SSB, CW, FSK and PSK
modes, while it is based on the step frequency of the
[MULTI/CH]
control when in the FM mode, and fixed at
100 Hz in the AM mode.
●
Scanning stops when signals are received while
performing Program Scan (VFO Scan) in the FM mode
or during Memory Scan (All-channel Scan or Group
Scan) or Quick Memory Scan regardless of the operating
mode. For more information on the conditions to resume
scanning, please refer to “
Configuring the Conditions for
Resuming Scan
” (
10-4
).
●
During standby for the CTCSS tone in the FM mode,
scan stops only when there is a matching CTCSS tone.
●
When the
[SQL]
control is turned to the right to a level
that far exceeds the squelch threshold while in the FM
mode, scanning may not stop even at a channel where
a signal is present. Configure the squelch level to a point
that is near the squelch threshold.
Starting the Program Scan (VFO Scan)
1
Press [M/V] to switch to VFO mode.
2
Press F5 [SCAN] to start program scan (VFO scan).
•
Pressing
F5 [SCAN]
again or
[ESC]
ends the Program Scan
(VFO Scan).
Configuring the Program Scan (VFO Scan)
Frequency Range
Scanning can be configured to the frequency range specified in
the memory channels for specific band segments (Program Scan)
or the entire RX frequency band (VFO Scan).
To perform Program Scan, register the memory channels for
specific band segments.
1
Press [M/V] to switch to VFO mode.
2
Press and hold F5 [SCAN] to display the VFO/
Program Scan configuration screen.
3
