Each ID in the block is unique. The left-most digit is the block number in the ID. The next two digits identify which fleet is active, and the last dig- it(s) (after the hyphen) identifies the subfleet.

The size codes selected by a Type I system designer depend on the spe- cific needs of the system’s users. Some organizations might want many subfleets with only a few radios each, while another organization might want only a few subfleets, with many radios each. To scan Type I systems, you must select or program a fleet map with the same size code assignments as the trunked system. If you do this accurately, you will track all the fleet and subfleet combinations used by the system. In other words, you will hear complete communications while moni- toring a trunked system.

Note: www.trunkscanner.com plans to make preset fleet maps available as they become known.

If you do not already know the size codes used, you will have to guess them. But since you do not have to fig- ure out all the blocks at once, this is not as hard as it seems. Select a size code for a block, then press SEARCH.

Now listen to the communications. If you decide you are receiving most of the replies to the conversations with IDs assigned to the block you just pro- grammed, then you have probably se- lected the right size code and can work on the next block of the map.

There are 16 preset fleet maps to choose from, and it is best to start with these when setting up a Type I or hy- brid trunk scanning bank. If none of the following preset fleet maps allow you to follow complete conversations, then you probably need to program your own fleet map (see “Program- ming a Fleet Map” on Page 44).
