the concept of the Scannable Object. A Scannable Object is
defined as “something that can be scanned”.
The Scannable Object concept is very important in the OOUI
design. Recall that one of the more frustrating things about
current trunking scanners is that entirely different methods of
programming and interacting with the radio are used depending
on whether the user is working with trunking talkgroups or
conventional channels. A method that works with one does not
work with the other. The user must learn two entirely different
“languages” for “talking to” the radio – one for trunking and one
for conventional, non-trunked frequencies.
What if it was possible to use the same basic “language”
regardless of whether a user is working with trunked talkgroups
or conventional channels, such that once a user has learned how
to enter a conventional channel into memory, they already know
most of what they need to know to enter a trunked talkgroup? Or,
a search range, or other “Scannable Objects”? This is how the
OOUI works – the two primary Scannable Objects, talkgroups on
trunked radio systems and conventional non-trunked frequencies
use the same user interface elements.
Additionally, we include limit and service search configurations
and Spectrum Sweeper configurations as Scannable Objects.
This means that it is possible to create, edit, group, scan and
delete service and limit searches, and SWPR configurations
using the same methods that are used when working with
trunked talkgroups and conventional channels.
Object Oriented Scanning also lends itself quite well to the
“collector hobbyist model” we describe above. Object Oriented
Scanning makes it very easy for newcomers to the hobby or the
radio to start off with a small collection Scannable Objects and
expand their collection as needed later. Object Oriented
Scanning makes it easy to group Scannable Objects in Scan
Lists, a powerful and flexible grouping system. Object Oriented
Scanning makes it easy to search for new frequencies or
talkgroups to monitor, and add them to existing or new Scan List
groups. Object Oriented Scanning makes it very easy to delete
or deactivate objects and Scan Lists that you do not want to
listen to, including a powerful temporary lockout mode that allows
you to zero in on activity associated with a specific incident, then
restore your desired configuration when the incident is over.
Finally, Object Oriented Scanning makes it exceedingly easy for
