4-1-2 Recalling quick memories

Once a few quick memory channels have been stored, key a different frequency into the VFO to assist
identification of recalled data (until you fully understand the process).
While in 2VFO mode
The LCD will display one of the quick memory channels which have been stored, use the
scroll through the list which contains up to ten frequencies. The star legend "
upper right of the LCD to indicate that quick memory recall is in operation.
Note: You will note that a maximum of 9 channels can be saved, this is because the
VFO frequency displayed when quick memory recall is executed is automatically stored
into one of the 10 locations... this allows you to return to the previous VFO display at a later
date without the data being lost and saves having to remember what the frequency / data
settings were.
To revert to the VFO frequency displayed prior to the execution of quick memory recall
, the " " legend will be removed from the LCD to confirm exit from quick memory recall.
Alternatively you may tune away from any displayed quick memory frequency using the main dial and
keys, the " " legend will be removed from the LCD to confirm exit from quick memory recall. The
effect (with careful use) is similar to adding a further 10 VFOs to the AR8200 !

4-2 VFO scan

You will be aware that the AR8200 displays two VFOs with the top VFO being the 'active' VFO which
monitors activity. At present you have to manually intervene by a
change between VFOs when monitoring duplex and semi-duplex channels (split frequency working when
a base station transmits on one frequency and a mobile on another such as VHF marine and public
service PMR... as opposed to simplex which is single frequency operation), this swaps the active VFO
between "V-A" and "V-B".
VFO SCAN causes the AR8200 to monitor the top VFO as PRIMARY and intermittently 'flicks over' to
check for activity on the SECONDARY frequency when the primary frequency becomes inactive.
If the active frequency remains busy then the secondary remains unchecked, if however the primary
becomes inactive (squelch closes) then the secondary is checked every few seconds for activity. If the
secondary frequency becomes active (during the time it is checked) the AR8200 will remain on the active
second frequency for a few seconds, the active secondary VFO lower font size increases to indicate that
the secondary VFO is being 'actively' monitored. The AR8200
will then return to the primary frequency to check for activity
where it remains for a few seconds... so the process continues
over and over.
To toggle the VFO SCAN facility on, use the VFO
environment menu which is accessed with the key
sequence
LCD will display "VFO MODE" with "VFO SCAN"
