ﬂeet map programming | Radio Shack 20-426 guide

Beyond the Basics

exact ﬂeet-subﬂeet hierarchy for a particular area is referred to as ﬂeet map programming, which is discussed further in this manual.

The disadvantage of a Type I system is that when PTT is pressed, the brief burst of data must contain the radio’s ID and its ﬂeet and subﬂeet. This is three times the amount of data a Type II radio sends, and as a result Type I systems usually accommodate fewer users than Type II systems.

Even though there are many Type II systems, Type I systems are still in use. There are also Hybrid systems which are a combination of both Type I and Type II. Your scanner defaults to monitor Type II systems, but it is possible to select a preprogrammed ﬂeet map or create a custom ﬂeet map for your area. For VHF and UHF Type II trunking systems, you will need to know the base, spacing frequencies and offset channels. See “Setting the Base, Spacing Frequencies and Offset Channel for Motorola VHF/UHF Trunked Systems” for details.

If you have programmed a trunk tracking bank for Motorola, press TRUNK to start multi-track, and you will see user IDs on the display. Since the scanner defaults to Type II systems, all the IDs will appear as numbers; however, if you notice a mix of odd and even user IDs, for example 6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or a Hybrid system.

You may also notice that you are missing responses when you hold on an active ID. Unlike Type II, Type I/Hybrid systems require a ﬂeet map that sets speciﬁc ﬂeet-subﬂeet parameters. It is easy to select a ﬂeet map for your scanner; what is not always easy is selecting or programming a map that matches your particular area.
