To improve your reading skills, start by reading every day for at least 15-30 minutes, since the more you read the easier it will become. Additionally, read out loud if you can, since reading out loud will help you learn more as you both see and hear what you’re reading. The BCD436HP is the first scanner to incorporate the HomePatrol ease of use in a traditional handheld scanner. Simply enter your zip code, and the BCD436HP will quickly select and scan channels in your local area. It's direct sibling is the mobile/desktop BCD536HP which includes a Wi-Fi Dongle, both utilize the same Sentinel.
Available atLast UpdatedDecember 26, 2015ContentsIntroductionHere we go again. Uniden has putout this fabulous scanner that will do a multitude of scanningachievement and you are here to find out how. This scanner isexceptionally harder to program for many (even seasoned programmers)because there is no printed manual and the CD manual is too cluttered.
I have written this manual to keep all of youfrom giving up hope, loosing you mind, trying to return your $500scanner, or all of the above. This manual is a culmination of the Wiki,the CD manual, (273 pages!?) of the BCD396XT Complete Reference, and all other previous ' and Uniden manuals.There are quite a few improvedand new features the 396XT has that the 396T didn't have.
Trunking systems let a large group of 2-way radio users (or evendifferent groups of 2-way radio users) efficiently use a set offrequencies. Instead of selecting a specific frequency for a transmission,the user’s radio selects a programmed trunking bank in the system whenthat user presses their PTT (push to talk) button.
When youprogram Motorola/P25 and EDACS system frequencies into the scanner, one frequency is thecontrol (or data) channel, and the rest are voice frequencies shared byall the users. There may be 3 or 4 frequencies assigned as (primary oralternate) control channels but only one control channel will be active ata time. These scanners will allow you to program just Motorola/P25 controlchannels into the trunking system and the voice channels willautomatically be found (but not programmed). EDACS systems need all the frequencies for thesystem programmed and in the correct (Logical Channel Number)order.The control channel is continually transmitted to the field units andhas a sound similar to listening to a boat engine over the phone (inmanual mode; you won't hear this when you are trunking the system.) Thiscontrol channel is also a good check to see if you can trunktrack thesystem.
If you can't hear a control channel when you step throughthe trunking frequencies (in manual mode), you either don't have all thefrequencies or are too far away to receive the control channel and thesystem. Motorola systems arelimited to a maximum of 28 frequencies per system or site. Ericsson EDACS systemsare limited to 25 frequencies per system or site. Motorola and EDACSsystems can be either analog, digital, or mixed (digital and analogtalkgroups). Mixed Motorola systems should be programmed as Motorolasystems and not P25 digital systems. That way the talkgroup options willallow you to select if it is a digital or analog.LTR systems work a little differently.
LTR systems typicallydo not have a dedicated control channel. This type of system encodes all trunkinginformation as digital subaudible data that accompanies each transmission. The frequencies also have to be in(Logical Channel Number) order or the correct 'slot' for the system totrunktrack properly.
Each repeater has its own controller, and all ofthese controllers are synchronized together. Even though each controllermonitors its own channel, one of the channel controllers is assigned to bea master that all controllers report to. Each of these controllers sendsout a data burst approximately every 10 seconds so that the subscriberunits know that the system is there. This data burst is not sent at thesame time by all the channels, but happens randomly throughout all thesystem channels.

If you listen to the frequencies of an LTR system inmanual mode (not trunking), on every channel in the system you will hearthis data burst that will sound like a short blip of static like someonekeyed up and unkeyed a radio within about 500 msec. LTR systems are limited to 20 frequenciesper system.Trunkscanningis basically scanning IDs that are programmed into IDlocations (same concept as frequencies into channels).You can then trunkscan just the programmed IDs. Trunktrackingis searching for all IDs in a system (sameconcept as searching for frequencies in a band).UnderstandingMulti-Site TrunkingSome Motorola andEDACS systems covering a very large geographic area usemultiple antenna sites that each operate on differentfrequencies and use the same talkgroup IDs for traffic. Each site willhave its own set of trunking frequencies and is monitored like a singlesystem. Each site can have its own quick key, so you can turn eachindividual site on or off while you scan.
Program your talkgroups intochannel groups within that system and all talkgroups in the system areavailable to every site so they don't have to be reprogrammed for eachsite. Since all sites share all the talkgroups within the system,multi-site trunking is much more efficient than programming each site asa separate system.RadioReference.com has an excellent page explaining the various typesof trunking systems in more detail.UnderstandingIDsIDsare what you see instead of frequencies when you monitora trunking system.Motorola IDs come in twoformats: Type I and Type II.
Each format displays anduses talk group IDs in slightly different ways. Type I/IIhybrid systems use both fleet-subfleet and 5-digitformats for talk group IDs.Type I IDs are in the format FFF-SSwhere FFF is the fleet and SSis the sub-fleet.

Type I systems are usuallyorganized with different IDs assigned todifferent fleets. For example, a validfleet/subfleet ID identifying all detectiveswithin a police department might be 000-12, where000 identifies all police IDs and 12 identifiesthe Detective division. To properly trunk a TypeI system, you have to program the fleet map forthe system.Type IIIDs areidentified by a 5-digit number.EDACS IDs come in twoformats: AFS and Decimal.AFS IDs are in the form AA-FFSwhere AA is the agency, FFis the fleet, and S is thesub-fleet. EDACS systems are organized withdifferent IDs assigned to different fleets andagencies. For example, a validagency/fleet/subfleet ID identifying alldetectives within a police department in anagency might be 06-101, where 06 identifies theagency (Police), 10 identifies the Policedivision (East side), and 1 identifies theDetective division.DecimalIDs areshown as a decimal number from 0to 2047.You canfind a chart showing Decimal and AFS IDs here:.I-Call IDS (Motorola/EDACSonly) are direct unit-to-unit transmissions that are notheard by other system users.
I-call IDs are usually6-digit IDs (ex: 700152).Unit IDS (orRadio IDs) are 7 or 8 digit numbers identifying individual radios. Note:To view unit IDs you have to turn the option on in the 'menu.LTR IDSare in the format A-HH-UUU where Ais the area code (0 or 1), HH is thehome repeater (01-20), and UUU is theuser ID (000-254).Turning onthe Scanner and Setting the SquelchNote: this applies to afresh scanner right out of the box or one that has been reset.Press and hold for about 2 seconds to turn on thescanner.
