Memory Skip Scanning; Priority Channel Monitoring - Yaesu FT-530 Manual

r
more than In-second to start the scanner. If the
transceiver is in the VFO or memory tune mode,
band scanning will result. Otherwise, in normal
memory mode, only the memories will
be
scanned.
The scanner pauses when a signal opens the
squelch, and the decimal point on the display
. blinks. When band scanning, a double beep will
sound each time the scanner reaches the band
edge, unless you have disabled the beeper (COCID

Scanning resumes according
to how you set the scan resume mode, described in
the following box.
You can stop the scanner manually by pressing
the PIT switch,
(TI
or
(D
key, which will leave
operation on the current frequency. Scanning is
also halted by (~)r (:~) or ~J, but operation
shifts to the respective new frequency in these
cases.
Memory Skip Scanning
When you have some very active channels
stored in memories you may wish to skip them
when scanning, but still have them available for
manual selection. You can mark a memory to be
skipped by pressing COCID
---7
@ID
while receiving
on the memory. A small "
~
" just outside the right
of the memory box indicates that this memory will
be skipped during scanning (although you can still
recall it manually).
To undo the scan-skip state of a memory, just
repeat the steps you took to disable it: select the
memory manually, and press COCID
---7
@.
Programmable Memory Scan
Besides band and memory scanning, the FT-530
can be set to tune or scan only the frequencies
between two frequency limits of your choice (with
the selected channel steps). These limits are stored
in the special memories labelled L (lower) and V
(upper):
o
Store the lower edge of the desired scanning
range in memory
L,
and the upper edge in mem-
ory
U.
o
With either memory V or L recalled, press
@
to enable memory tuning, as described pre-
viously
("m~"
must be visible below the mem-
ory box). The frequencies stored in memories L
and V now limit your tuning and scanning range
to the resulting subband. If either ARS or man-
ual repeater shift is activated, repeater offset is
applied automatically when you transmit (even
33
-~_---=------========"""""''''''''''''''''''''''''''''''''''----------
34
if the resulting transmit frequency is outside the
subband limits).
Note: The frequency resolution of subband limits is
100 kHz, although the channel resolution of memories
L and V is the selected channel step size. Therefore the
actual subband limits are the frequencies stored in
these memories rounded down to the nearest 100 kHz.
Since the memories themselves are not limited to a
specific frequency, you can still use them for other
purposes on any frequency within the 100-kHz range
above the intended subband limit.
Example: To limit reception to 145.0 - 145.9 MHz
o
Tune a VFO to any channel between 145.000 and
145.095 MHz.
o
Hold
~
for 1/2-second, tune the selector knob
so that L appears in the memory box, and then
press
QIID
again momentarily. The displayed
frequency is now stored to provide a lower sub-
band limit of 145.000 MHz.
o
Retune the VFO to any channel between 145.900
and 145.995 MHz.
o
Repeat the second step, selecting Vin the mem-
ory box. This stores the effective upper subband
limit of 145.900 MHz.
o
Press
@
to change to memory operation, and
@
again to activate the 145.000 -145.900 sub-
band limits for tuning and scanning. Note that
when scanning the subband, as with band scan-
ning, a double beep sounds each time the scan-
ner reaches the subband edge, unless you have

Priority Channel Monitoring
The priority function automatically checks for
activity on a memory every five seconds while
operating on a VFO or other memories. When the
receiver detects a signal on the priority memory,
operation automatically shifts to that memory
while the signal is present (plus a few seconds). If
you transmit while paused on the priority mem-
