Scan types
Scan types
Operation
(Scan function is enabled in the Main band)
VFO SCAN
Used to detect a signal by automatically changing the frequency in the VFO mode.
Programmed scan
Repeatedly scans between two Scan Edge frequencies.
The edge frequencies are programmable, and are preset in P1 and P2 as the default. (pp. 61, 64)
Fine Programmed scan
If the squelch opens while scanning, the tuning step changes to 10 Hz. This reduces the
scan speed, but the transceiver keeps scanning.
MEMORY SCAN
Used to detect a signal by automatically scanning the memories in the Memory mode.
Memory scan
Repeatedly scans all entered Memory channels.
Select Memory scan
Repeatedly scans all or one of 3 select Memory channels.
∂
F SCAN
Repeatedly scans within the
∂
F span area.
The scan starts from the center frequency. (p. 71)
Fine
∂
F scan
If the squelch opens while
∂
F spanning, the tuning step changes to 10 Hz. This
reduces the scan speed, but the transceiver keeps scanning.
Preparation
D
Squelch status
Scans work with the Main band’s squelch status.
Be sure to adjust the squelch level according to your
operating environment.
L
Normally, set
AF
RF/SQL
to the point where noise
disappears, and the TX/RX indicator goes OFF.
When the scan starts with the squelch open:
•
For a Programmed scan
When the tuning step is 1 kHz or less, the scan
continues until it is manually stopped— it does not
pause* even if signals are detected.
* The scan pauses when the squelch is closed and then
opened. The scan resumes after 10 seconds has passed
when the Scan Resume function is ON. It is cancelled
when the function is OFF.
When the tuning step is 5 kHz or more, the scan
pauses on each step when the Scan Resume
function is ON. It does not pause when the function is
OFF.
•
For a Memory scan
The scan pauses on each channel when the Scan
Resume function is ON. The scan does not pause
when the function is OFF.
When the scan starts with the squelch closed:
The scan stops when a signal is detected, regardless
of the tuning step.
• When the Scan Resume function is ON, the scan pauses
for 10 seconds after detecting a signal, then resumes 2
seconds after the signal disappears.
