107 Appendix User Defined Fleet Maps Type I Programming Information When a Type I system is designed, the address information for all the ID’s 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 are tracking. Each size code determines the number of fleets, subfleets, and ID’s 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 ID’s. 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 ID’s display on your scanner depend on the block number and the block’s size code. When a Type I ID appears, the leftmost digit represents the block which contains the ID. The next 2-3 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 might want many subfleets with only a few radios each, while another organization might want only a few sub- fleets 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. If you don’t already know the size codes used, you’ll have to guess at them. But since you don’t have to figure out all the blocks at once, this isn’t as hard as it seems. Select a size code for a block, and then press Scan. Now listen to the communications. If you decide you are receiving most of the replies to the conversations with ID’s assigned to BC246T Paper OM 062405.fm Page 107 Tuesday, June 28, 2005 10:12 AM
108 Appendix the block you just programmed, then you’ve probably selected the right size code and can work on the next block of the map. Finally, for most public safety systems there are some size codes which are more common. S-3 and S-4 are probably the most common, followed by S-10, S-11, and S-12. Size Code Restrictions If you select size code S-12, S-13, or S-14, there are some restrictions as to which blocks can be used for these codes. S-12 can only be assigned to Blocks 0, 2, 4, or 6. S-13 can only be assigned to Blocks 0 and 4. S-14 can only be assigned to Block 0. Since these size codes require multiple blocks, you will be prompted for the next available block when program- ming a fleet map. For example, if you assign Block 0 as an S-12, you will be prompted for b2, the next block avail- able, instead of b1. And if you assign Block 0 as an S-14, you would not see another prompt because it uses all available blocks. BC246T Paper OM 062405.fm Page 108 Tuesday, June 28, 2005 10:12 AM
109 Planning PlanningCollecting Information Getting your scanner programmed and scanning takes a few steps. This helps guide you through these steps that will make it easier for you to start scanning. 1. Collect information about the system(s) you want to monitor. Do you want to listen to your local police and fire departments? How about the highway patrol, ambulance service, and aircraft? You might even want to listen to your local utility company as they track down a break in electrical service in your area. Make a list of the agencies you want to listen to, then look up the frequencies and systems used by those agencies. The Internet is a great source for current frequencies and information about scan- ning. Here are a few useful sites: •http://www.scannermaster.com/ - frequency resources and home of Police Call. You can also call them at 1 800 SCANNER (hours are from 10:00 a.m. to 5:00 p.m. Eastern Time Monday through Friday.) •http://www.radioreference.com/ - the Internets premier source for user-supported radio system information. •http://www.bearcat1.com/ - frequency information from National Communications. •http://svartifoss2.fcc.gov/reports/index.cfm - conventional frequency information on file with the US Government Tips: • Scanners are designed to monitor complex radio systems. That means that programming your scanner might seem like a daunting task at first. Be patient if you dont get it right the first time. You can also seek out help locally for the systems you want to scan by visiting the forums section of http://www.radioreference.com/forums. • Before you start to program your scanner, decide how you want to organize the frequencies you want to scan. For example, some areas are best organized by Planning BC246T Paper OM 062405.fm Page 109 Tuesday, June 28, 2005 10:12 AM
11 0 Planning geographic location (east, north, south, west, central, etc), while others are best organized by agency (police, sheriff, ambulance, fire, etc.). You might even find it easier to organize a mixture of frequencies (north, southeast, and west for police but fire all in one group for example). 2. Organize the system information using these system worksheets included in this appendix. • Use “Conventional System Worksheet” on Page 114 to organize info about conventional frequencies. • Use “Motorola System Worksheet” on Page 115 to organize information about Motorola frequencies. • Use “LTR/EDACS System Worksheet” on Page 117 to organize information about LTR and EDACS frequencies. 3. Follow the instructions in “Filling Out The Conven- tional System Worksheet” on Page 110, “Filling Out The Motorola Worksheet” on Page 111, and “Filling Out the LTR and EDACS Worksheet” on Page 113 to program your scanner. Tips: • Before you start, make as many copies of the worksheets as you think youll need. You can also go to the download section of http://www.uniden.com/productsupport.cfm and download the worksheets there. • All worksheet instructions assume that you have completed the critical Step 1 (collecting the system information). Dont skip this step. • Use a pencil to fill out the worksheets. This lets you change information if necessary. Filling Out The Conventional System Worksheet System Name and Quick Key Fill in a name that describes the system you want to create. For example, you can enter Dallas Police or Amateur Radio here. If you want to store more than one type of frequency, you can enter Mixed. BC246T Paper OM 062405.fm Page 110 Tuesday, June 28, 2005 10:12 AM
