[. . . ] 500-Channel Trunk Tracking Scanner TRUNK TRACKER III UBC780XLT Introduction The UBC780XLT is a state-of-the-art radio with TrunkTrackingTM and automatic scanning capabilities. It can store frequencies such as police, fire/emergency, marine, railroad, air, amateur, and other communications into 10 banks of 50 channels each. Use your new scanner to monitor: · Police and Fire Departments (including rescue and paramedics), and Ambulance Services Private and Government Trunked Systems · VHF High Band, UHF, 800MHz · Trunking for Motorola, EDACS and LTR Systems · Business/Industrial Radio · Utilities · Marine and Amateur (ham radio) Bands · Air Band · And much more. . . The chart below identifies the scanner band numbers, the frequency range, the modulation mode and the default step size settings. Band No. [. . . ] · Repeat Step 7 for every trunk frequency entered. Selecting Trunking Programming Menu Mode To change the system type which your scanner monitors, you must be in the Trunking Programming menu mode. Select the bank you want to program using v, w or VFO and then press E. Remember!Also instead of pressing E, you can press the VFO/SELECT control or press the SELECT/MUTE key. Selecting Trunking System Type 1. Select TRUNK TYPE using v, w or VFO and then press E, SELECT or VFO. 2. Select the system type you want to program using v, w or VFO and then press E, SELECT or VFO. 34 Setting the Squelch For trunked reception, a good setting for the SQUELCH control is in the centre of the range with the red marker pointing up. If set too high (CCW) in some cases it could prevent your scanner from locking to the control channel reliably. If set too low (CW) it will slightly delay finding the control channel. The best setting is the same as for conventional reception, and is not critical. Receiving Trunked Systems When you have properly programmed all the frequencies for a trunked system, you can receive the system several different ways. You will find that Search, Hold, Lockout, Scan and Manual are all similar to conventional scanning. TRUNKED SEARCH lets you hear all system talkgroup activity (unit-to-unit I-Calls may be received as well). ID HOLD works with Search mode to let you quickly freeze reception on an interesting transmission. ID LOCKOUT works with Search to exclude talkgroups that you don't want to hear. ID SCAN lets you receive only those talkgroups that you store in Scan Lists. MANUAL lets to selectively listen to a talkgroup in your Scan Lists When receiving EDACS systems, remember that Uniden's AFS talkgroups give you powerful flexibility. In a few keystrokes, you can specify a single talkgroup, a fleet, or an entire agency in all the above modes. Read the section "EDACS Reception" to understand how this works. Trunked Search Once you have programmed all the frequencies for a trunked system, SEARCH will let you immediately start hearing transmissions. Press SCAN, and select the bank(s) you wish to receive, just as you select banks in conventional scanning. You will hear the control channel and see active talkgroups on the screen. You will not hear the voice transmissions in MONITOR mode. Hint: MONITOR mode is an excellent way to observe system activity and determine which talkgroups are most active. You should read the appropriate parts of this guide to understand the formats. 35 The bottom line of the display indicates the Bank and the type of trunked system you are monitoring. Regardless of the system, you won't know exactly who you are receiving until you listen for a while. Of course, figuring out who each ID represents is half the fun of TrunkTracking. Later, when you learn more about a system, you will want to store lists of talkgroups. [. . . ] Some organisations may want many subfleets with only a few radios each, while another organisation 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 FleetSubfleet combinations used by the system. In other words, you'll hear complete communications while monitoring a trunked system. [. . . ]
