User manual UNIDEN BC785D

[. . . ] . 95 iv Introduction The BC785D is a state-of-the-art Digital Capable radio with TrunkTracker III and automatic scanning capabilities. It can store frequencies such as police, fire/emergency, marine, railroad, air, amateur, and other communications into 10 banks of 100 channels for a total of 1000 channels. With the optional BCi25D, APCO P-25 Digital Card installed you can monitor Public Safety Organizations who currently use conventional, Trunked at 3600 and Mixed Mode APCO 25 systems. Use your new scanner to monitor: · Police and Fire Departments (including rescue and paramedics) · Trunking for: Motorola Type I Type II Type I & II: (Hybrid) EDACS Wide band Narrow band Scat LTR Digital Communication for: APCO Project 25 Conventional Tranked at 3600 Mixed Mode at 3600 · NOAA Weather Broadcasts · Business/Industrial Radio · Utilities · Marine and Amateur (ham radio) Bands · Air Band · And much more. . . [. . . ] For details on the operation and programming for all of these systems, see pages 45-71. When tracking these types of systems, remember these important points: · Your scanner defaults to monitor Motorola Type II systems; however, you can change this if the system in your area is different. (The types of systems are discussed below. ) · The frequencies for many of the trunked public safety systems are listed in the TrunkTracker National Public Safety Trunked System Frequency Guide included with your BC785D scanner. · If you have internet access, you can visit scanner. uniden. com or www. bearcat1. com/free. htm for additional information, for current news and frequency information, about Trunk Tracking Scanning. * Motorola, SMARTNET, and PRIVACY PLUS are trademarks of Motorola Inc. Johnson Company. 45 Programming and Receiving Digital and Trunked Systems There are three steps for programming a trunked sytem: 1. Program the Trunk Type ­ What type of system will the scanner be tracking, Motorola Type II, Type I, EDACS, LTR, etc. Program the Trunked Frequencies ­ Within a trunked system, the frequencies are shared among all the users, called "Talk Groups". · Within the bank you decide which channels to program the trunked frequencies. Program the Talk Groups ­ Within the trunked system, each agency or department is assigned a Talk Group ID. This ID must be programmed into the scanner in order for it to monitor that specific agency or department. · When programming you decide which "Location" to program the "Talk Groups". Here you need to program Talk Group ID's into Locations. STEP 1: Selecting or Changing Trunking System Type Before using the Trunk Tracking system, you must select the bank and trunk type. You can only track one trunked system per bank, total of 10 trunked systems. You can also enter the Trunk Tracking programming mode by pressing TRUNK. 3 Select the bank number using the keypad or the VFO and pressing E. C 001 OOOO. 0000 1:TRUNK TYPE 2:TRUNK CHANNEL C 001 OOOO. 0000 1:TYPE2 800 2:TYPE1 4. Select 1:TRUNK TYPE / 1:ON and the system type you want to track by rotating the VFO and pressing E. For Type 1 System, you must enter the block and fleet numbers. Please refer to "Programming a Fleet Map" on page 64 for instructions. 1 2 3 4 5 6 7 8 9 LCD display Icon TrunkingType Type 2 800 M Motorola Type 2 800 MHz Type 1 M Motorola Type 1 Type 2 900 M Motorola Type 2 900 MHz Type 2 UHF M Motorola Type 2 UHF Type 2 VHF M Motorola Type 2 VHF EDCS WIDE E EDACS Wideband 9600 baud EDCS NARROW E EDACS Narrowband 4800 baud EDCS SCT. Must program frequencies in exact order and location. Note: Information on APCO P-25 Systems are referred to in "APCO Project 25 Reception" on page 68. STEP 2: Programming Trunking Frequencies After you finish selecting the bank and trunk type you want to track, store the frequencies in the channels for your selected bank in your scanner. Important: If you are programming an EDACS or LTR trunked system, you must enter the frequencies in a specific order. Check the frequency guide included with the scanner for the frequencies in your area. [. . . ] 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. If you decide you are receiving most of the replies to the conversations with IDs assigned to the block you just programmed, then you've probably selected the right size code and can work on the next block of the map.
