Priority Scan - Yaesu FRG-100 Operating Manual

tuning step size. When activity is de- tected, scan-
ning will stop on that frequency, then resume ac-
cording to the delay mode selected (time or carrier).
Priority Scan
Priority Scan is useful for "keeping watch" on a
frequency of interest (such as an emergency or
hailing frequency), while still being free to tune
around or listen elsewhere. Any single memory
channel (except
: {
I
and
Lo)
can be tagged as the
priority channel.
While receiving in VFO or Memory mode, the
priority channel will be automatically checked
once every 5 seconds for activity. As this happens,
your frequency display will momentarily revert to
the priority channel, and then return to normal. If
activity is received during a scan, the radio will
automatically switch to the priority channel for
monitoring. In the default (carrier delay) mode,
operation will resume to the previous VFO or
memory channel 2 seconds after signal activity
ceases. In the alternate (time-delay) mode, the pri-
ority channel will be monitored for 5 seconds, then
operation returns to the previous VFO frequency
or memory channel regardless if activity continues
on the priority channel (it will be caught on the
next scan). Carrier and Time Delay modes can be
toggled using the power-on sequence as described
before
(See: M e m q scan).
To tag a selected memory channel as the prior-
ity channel, press SCAN SEL until "PRI" appears
above the memory channel number at the right
side of the display Then, from either memory or
VFO operation, simply pressing SCAN will begin
priority scanning.
Example: Priurity scan memory channel
10
while in
VFO operntion.
0
Press VFOIMEM to select memory operation,
then recall channel
! : 1
.
0 Press SCAN SEL until "PRI" appears above the
memory channel number.
M E M
0 Press VFOIMEM to return to VFO operation,
then press SCAN.
Priority scan will now begin, you are still free to
tune as before.
Selectable Group Scan
This versatile scanning mode allows you to scan
memory channels by an assigned group or pattern.
In Memory Scan, all fifty memory channels are se-
quentially scanned, any channels that you do not
want to scan must be individually de-selected or
"locked-out". This can be inconvenient, especially
if there are multiple channels you wish to lock out,
but later want to quickly select again for scanning.
Selectable Group Scanning allows you to ar-
range your 50 memory channels into 5 groups each
containing 10 channels. Each memory channel is
given an alphanumeric designation (such as
I%,
E
7,
etc). The
letter refers to the group that it belongs to,
while the
number refers to the channel within each
respective letter group. Any single selected group
(ten channels) can be scanned, or a common chan-
nel number among all groups (five channels) can
be scanned. Groups and channels can be arranged
according to mode, band, or any significance you
choose. The chart below illustrates how the memo-
ries are arranged by lettergroup and channel-num-
ber.
There are two options in this mode, scanning by
common
letter group or common channel number.
This is visually simplified in the above chart if you
think of group scanning as horizontal scanning, and
common channel scanning as
vertical scanning.
Memory Usage
Please note that the common fifty memory
channels are used in both Memory and
Group Scanning modes, only the assignment
is different.
For example, memory channel 42 would have
an assignment of
"E?"
(group "En, channel
"2") in Selectable Group Scanning mode, but
the memorized frequency contained within
would be the same in both modes.
