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 monitoring a trunked system.

Note: Preset fleet maps might be available at www.trunkscanner.com.

If you do not already know the size codes used, you will have to guess them. But since you do not have to figure out all the blocks at once, this is not as hard as it seems. Select a size code for a block, then press SRCH. Now lis- ten to the communications. If you decide you are receiv- ing most of the replies to the conversations with IDs assigned to the block you just programmed, then you have probably selected 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 tracking 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 “Programming a Fleet Map” on Page 49).
