As posted on CONNSCAN, Windsor is going trunked in the not too distant future. Try 453.5375 to hear the Passport LTR key up. Unsure at this time who is moving to the system.

Town of Windsor will be switching over to "Passport LTR" the first week of June.
Testing of system is now under way,
Testing of system is now under way,
Windsor & LTRTrunk
Trying to monitor the Windsor system with LTRTrunk and LTRDump, I get a strange combination of Passport and Multinet. I cannot easily get the LTRTrunk to lock on the system without going to "Regular LTR, system 0000".
A dump file shows multiple Multinet lines and only a few passport lines. I am not sure if the unloaded, idling system is confusing LTRTrunk/LTRDump

System is not up and running full yet.
It is going on-line June 2, "Passport" system can not be run on any scanners as of yet.

Hello,
I fixed some of the problems with incorrect multinet comming up. It is a side effect of passport check not being used in the past. I made changes to the code that deals with the ltr bursts. I am also working on LTRTrunk showing Neighbor site frequencies, affiliations, and home channel assignments.
I got some strong lift last night into this morning and actually logged some bursts from the Windsor system. The neighbor frames are similar to Bloomfield site 1 with no neighbors defined and a 'configuration' word of 0015 hex. I suspect that the 1 is the network id and the 5 represents the frequency band (450 to 470).

Windsor PD (t/g 54598) is running on the trunked system. Bloomfield is running 59xxx t/g numbers so it looks like the intention is to not duplicate system ID and t/g #'s, this would likely be necessary to allow interoperability down the road.
System ID is 000c.
FD may be looking at a June 8th changeover date. 453.8000 will be a paging/dispatch freq and is not likely to have a simulcast of fireground traffic.
I have to start LTRTrunk on 453.5375 and once it recognizes the system, go to 453.4750.
End of transmission keeps the second scanner open a bit longer than needed when delay is turned on. Perhaps there is an EOT code/signal transmitted?

As a side note for the listeners out there...
"System A" will be the primary Windsor system while "System B" will be the backup/Marcus Communications commerical side.
East Windsor is holding off on their upgrade and doing the wait and see with Windsor's.
Windsor is also using a Orbcom radio/telephone interface for it as well. Looks pretty neat.

Hello,
With the ability of having 127 sites and thousands of IDs and talkgroups I know I would plan the system out not to duplicate talkgroups or site IDs. There may also be some benefits like the ability to share some equipment between all the sites.
The LTRTrunk program has not been "tuned" as I am still in the process of figuring out how Passport works. So the tracking of LTR will be alittle rough for awhile.
Passport is tough because I have to spend hours figuring out how the protocol works. I can easily see another year or so before there is a refined program.
Thanks for the logs and the feedback.

was monitoring windsor passport LTR yesterday on 453.475 the old pd freq. was listening to radio service setting off pagers and so forth , monitored the pd , and i thought i heard what might be DPW on the freq. as well , again turned off the delay with no pl. programmed to monitor the trunk. sucks listening to every dept. on one freq. but guess its better than getting nothing at all !
ok if the systen only uses existing freqs as it looks in the last post, why not just assign different pl's?

LTR systems do not use PL's. They get their information with the same concept of 800 trunking systems...which also do not use PL's.
However, in the case of Windsor, they send out the paging tones the same way. Before LTR, they sent out the pages on their ops freq with PL.
