[. . . ] ww w 500-Channel Trunk Tracking Scanner BC780XLT TRUNK TRACKER III Introduction The BC780XLT 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. With the new SmartScannerTM feature, you can also automatically program your scanner by downloading directly from our Uniden/Bearcat national frequency database via a PC or external modem. Use your new scanner to monitor: · Police and Fire Departments (including rescue and paramedics) · VHF High Band, UHF, 800/900MHz Trunked Public Safety Systems · Trunking for Motorola, EDACS and LTR Systems · NOAA Weather Broadcasts · Business/Industrial Radio · Utilities · Marine and Amateur (ham radio) Bands · Air Band · And much more. . . [. . . ] 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 will hear talkgroups and see them on the screen. 39 Talkgroups display differently in Motorola, EDACS and LTR systems. You should read the appropriate parts of this guide to understand the formats. 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 awhile, or refer to frequency guides or internet sites such as www. trunktracker. com. 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. Then you can scan specific agencies and users, and use the many other features your radio provides. ID Hold and Direct Entry ID Hold Mode Just like in conventional Search, HOLD lets you pause ID Search on an interesting transmission without storing the talkgroup into memory. If you hear an interesting ID during SEARCH mode, and want to continue listening to it -· Press HOLD/L to stop the search. If you want to listen to a specific ID, while in HOLD -· Use the keypad to enter the ID you want and press HOLD/L. If you want to stop holding -· Press SRCH to return to Search Mode. ID Lockout Like conventional scanning, it's possible to lockout unwanted traffic. This is particularly important in trunked systems because in many areas, water meters, door alarms, traffic signals, and other mechanical devices are assigned IDs just like other users. Also some departments scramble or encrypt their communications, and you may want to lock out these unintelligible broadcasts. Note: If you lockout an ID in Search mode, it is also locked out in Scan List mode. [. . . ] 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.
