Programming Fleet Maps
If you programmed a trunk tracking bank and press SRC, talk group ID’s appear. Since
your scanner defaults to monitor Type II systems, most if not all ID’s appear as even
numbers. However, if you notice an even mix of odd and even talk group ID’s, for example
6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or
Hybrid system.
You might also notice that you are missing responses when you hold on an active ID.
Unlike Type II systems, Type I/IIi systems require a fleet map that sets specific fleet-
subfleet parameters. It’s easy to select a fleet map for your scanner; what isn’t always
easy is selecting or programming a map that matches your particular area.
There are 16 preset fleet maps listed in the appendix that you can choose, and these are
usually a good place to start when setting up a Type I/IIi trunk tracking bank. If you choose
a preset map and still have difficulty following complete conversations, then you’ll have to
program your own fleet map.
