a possible way to track LTR Passport with BC296...

[mr_hankey]

i came up with a crude way to track an LTR Passport system using the Uniden BC296 - if 2 conditions are met...

1) the Passport user must not be mobile outside of the current Passport site
2) the Passport system cannot exceed 10 frequencies per site

example: a hotel using a Passport system for local operations.

using LTRTrunk, i am able to determine a set of 6 frequencies make up LTR Passport Site 1034.

i plug each of the 6 frequencies into it's own memory channel IN 6 SEPARATE BANKS in the 296.

each frequency is then assigned Priority Status, "P"

when a user of interest comes up on the system, the owner of the BC296 can activate the Priority Plus feature of the scanner and instantly track all channels assigned a "P"...if an unwanted user stalls the frequency, the owner of the BC296 can just press RSM and keep tracking all the frequencies in the system.

i know it's crude, but it appears to work better than the 780 "negative delay" for LTR Passport systems trick.

once again, you will not be able to track mobile users roaming from site to site, nor will you be able to plug in more than 10 frequencies for the Passport system you want to monitor (there are only 10 banks in the 296 that can be assigned Priority status...)

Hey this could also be done with a PRO-94, PRO-2052,... any scanner with up to 10 priority Chans. As long as your not interested in any other systems and only monitor the LTR system this could work nicely. Neat trick!

Very good. That's thinking outside the box. :idea:

thanks - i've been beating up on some local LTR Regular and LTR Passport systems all day since 7am.

starting to slowly go crazy... : )

one other thing to keep in mind with LTR Passport systems: if your desired user is airborne (News chopper, etc), you can figure out the frequencies with the aid of LTRTrunk or ltrunk.exe and then calculate the INPUTS (usually 5Mhz offset) and program them into a bank in conventional mode.

doing this will almost guarantee picking up airborne comms before anything else in the area (airborne users having a higher elevation and all that...)

Don't have any passport system here in SF bay area, but plenty of regular LTR systems.
But you idea is workable for some conventional non trucked systems, Great idea.

ok, looks like this needs some added detail.

1) program all the Passport frequencies into their appropriate bank channels (one per bank, remember)
2) mark all Passport frequencies as Priority
3) initiate a scan of ALL banks, 1-10
4) activate the Priority Plus feature by pressing PRI button twice while scanning.
5) this will get you into a mode where all PRI channels are scanned in banks 1-10, but will stop on an active comm and not move on.
6) to get all Priority channels to be checked every 2 seconds, just stop on a Priority frequency (say, channel 1000) and keep it there - the 296 will monitor channel 1000 and every 2 seconds, check every other PRI channel and go to active comms on that channel.
7) in this final mode, you can actively monitor all 10 channels without touching any buttons - they will all check each other every 2 seconds in Priority Plus mode.

good news:

you can actually track 11 frequencies using the above method.

the individual Priority Plus frequencies in each of the 10 banks, plus the one you roll to with the VFO knob.

so let's say your Priority Plus channels in the 296 are:

100
200
300
400
500
600
700
800
900
1000

once programmed, you just "roll" to channel 101 and now you are monitoring 11 frequencies (10 priplus and the one you stopped on in 101 which gets returned to every time priplus is "resting")

:lol: SOMEBODYS always thinking out here in scanner land , thank god for that !!! great posts you guys , iv gotta laugh......but an even better way to track these systems (LTR PASSPORT) ........is for GRE AMERICA >radio shack< to come out with LTR PASSPORT TRUNKING with the new base / mobile thier supposed to be coming out with and beat uniden to the punch like uniden did with digital ...would be nice wouldnt it ??

PRO-83 added to the Passport "Tracking" tools..

And now we have the RS PRO-83 to add to this list.. 10 Priority Chans.. that adds it to the list of tools for "tracking" an LTR Passport system.
