User Defined Fleet Maps

Type I Programming Information

When a Type I system is designed, the address

information for all the IDs is divided into 8 equal sized

blocks, numbered 0–7. When you program your scanner to

track a Type I system, you must select a size code for each

of these blocks. When you have assigned a size code to all

8 blocks, you’ll have defined the Fleet Map for the system

you’re tracking. Each size code determines the number of

Fleets, Subfleets, and IDs each block will have. For

example, a size code of S-4 has one Fleet, which is divided

into 16 separate Subfleets, and it has a total of 512

individual IDs.

When a block is assigned a size code, the Fleet or Fleets

created within the block are assigned a Type I ID. The way

these IDs display on your scanner depend on the block

number and the block’s size code. When a Type I ID

displays, the leftmost digit represents the block which

contains the ID. The next two digits identify which Fleet is

active, and the last digit(s) identifies the Subfleet.

The details concerning how the size codes are selected by

a Type I System designer are highly dependent on the

specific needs of the system’s users. Some organizations

may want many subfleets with only a few radios each,

while another organization may want only a few subfleets

with many radios each. Your task is to program your fleet

map with the same size code assignments as the trunked

system. If you do this accurately, you’ll track all the

Fleet-Subfleet combinations used by the system. In other

words, you’ll hear complete communications while

monitoring a trunked system.
