Thanks Denny, 153.605 and 153.335 must of just become active because I get a constant 5 full bars on both of these frequencies and never saw anything on these frequency before in Fort Erie. If I put these two sites into my scanner as standard LTR SYSTEMS will they trunk track and will I receive audio on the talkgroups.

Yes, you can load the site frequencies into your scanner just like normal LTR sites, matching the LCN numbers to your scanner channel numbers, if your scanner requires that.

I'm finding that the Mobiletech LTR-Net talkgroups are only unique to the last 3 digits, across the network, and not distinct to each site, like normal LTR talkgroups. For example, talkgroup x-xx-065 might show up as 0-01-065 or 1-11-065, depending on which site/LCN they are roaming on. This allows a radio to roam on any site, yet still talk to the rest of their talkgroup, wherever they are located, without having an address collision with an existing user on the roaming site.

Mobiletech uses Fleetsync to augment the LTR-Net talkgroups, which provides unique identifiers for close to a million users. This enables the network to page a specific user, no matter where they are located, without having to ring up the entire LTR talkgroup. The fleetsync identifiers recovered so far are on the wiki page, linked off of the RR Mobiletech network page.

I am using my ARCPRO Software to log everything and it's been running on both of the sites I found, but there is no traffic as of yet but that does not surprise me seeing it's Christmas and the Holidays so I don't think the sites will be to busy tonite.

I just hooked up my new Funcube Dongle Pro Plus to my Royal Discone, and I can 'see' the Mobiletech Lockport site 153.605 Home Status Channel at 115 miles away.

With my Funcube Dongle Pro, I could only see out to ~75 miles.

What an amazing device ... and Western NY is very flat.

I suspect Site 62 is Medina. The Medina School Bus system that I hear on Rochester (TG -097) are too far away for Rochester to be their primary site. Lockport is closer to Medina but I suspect there must be a local site near Medina for the quality of the coverage they have.

I can not hear anything from my location in Rochester for the frequenies on their WQPU255/WQOB319 licenses for Medina.

I see an exception to that with TG 0-05-031 being listed in the RRDB as both Hanibal Central Schools on Hanibal and the LA&L RR on Rochester. I know that 0-xx-031 is valid for the LA&L Dispatcher TG. The HR varies with the Home Status Channel at each site they use.

The two possibilities I see is that either the Hannibal listing is in error or Mobiletech TGs are unique only in the part of the network where a particular user operates. LA&L is in Livingston, Steuben and Monroe County and Hannibal is probably just Oswego and maybe northern Seneca.

Well it took almost 17 hours of listening but finally got some traffic on the two towers I found in my area,

Lockport Tower
1-05-097 = some one checked in but Unknown at this time
1-05-253 = Dead Carrier

Tonawanda Tower,
1-09-097 = Short burst of Audio from Male but still Unknown at this time

I'm sure after the Holidays The towers will get busy.

Talkgroup x-xx-253 is one of the LTR-Net special talkgroups, and is used to call as a unique radio address message. If you run LTR-Analyzer against it, you'll see a start call (x-xx-253), followed by a x-17-xxx unique radio address message, followed by a x-31-253 end call message.

I belive this is the MobileTech network paging a unique LTR-Net radio, so that it can send something to the radio.

Tonawanda, Erie Site 153.335 MHz
I see there is a Neighbor 31 coming up in the log is this the Attica site you already have ???

I'm seeing a very weak Home Status Channel on 152.390, which matches the Mobiletech license for Boston (Erie), WPQE699. This may be site 62.

K2HZ, I discovered today that the Attica site has expanded by 2 channels. Attica has great coverage over the thruway from Buffalo to Rochester, including Medina. I didn't see anything new in the Medina area. For some reason, Attica's Home Status Channel wasn't broadcasting, but the 5 other channels were.

I found site 62 ... it's a single LCN site in Centerville, but doesn't have a Home Status Channel.

Rochester's VHF band is like a desert compared to Syracuse :-)

Seeing there are towers around Buffalo NY, (IE) Tonawanda, Lockport and so on, is it fair to think that they will have a Tower right in Buffalo NY, just wondering.
