LMRN Technical Data Discussion

[Forts]

Unfortunately I'd say you are likely correct.

Site 51 has shown up on Whitby's neighbour list.

Site: 1.51
Channel 0-858: 142.4400 CC

Site: 1.37 NAC=AD7 ; Whitby
Neighbor: BEE00.AD9-1.13 ; Niagara Falls
Neighbor: BEE00.AD9-1.26 ; Sunderland
Neighbor: BEE00.AD9-1.38 ; Pontypool
Neighbor: BEE00.AD9-1.39 ; King City
Neighbor: BEE00.AD9-1.40 ; Toronto
Neighbor: BEE00.AD9-1.51
Neighbor: BEE00.AD9-1.147 ; Toronto

It's using one of Cobourg's control channels. Zone 2 starting?

Just a guess, but I'll bet Durham EMS are screaming about really poor radio coverage in the Newtonville / Kendal Hills area of east Clarington in Durham Region.
They are probably trying to make a rapid intervention and fix coverage that mostly worked on Analog but wont on P25 TDMA.

zoom in
Bell Mobility has a cell tower at the Newtonville Water Tank to solve this gap for 800MHz.
I'll bet that they add a new VHF site at Newtonville Bell in the next 24 months.

An associate in Cobourg says that 142.440 is pounding in locally. So its safe to say 1.51 is LMRN Cobourg.

 

[gary123]

It looks like all the converted LMRN sites now have a dedicated data channel. I am not 100% sure what is being sent but it appears that only units on the site use the data channel for that site. Its not linked to any other site. I do see a neighbor site list on the data channel.

theses are the data freq I have located so far.
site 12 - 142.035
site 18 - 142.485
site 21 - 141.300
site 33 - 142.305
site 45 - 141.675

 

[Muxlow]

I am seeing a data only frequency on all the sites now too
And just about every site seems to have its own little control channel for data also. Dont give frequency or any info other then the site number

 

[w3rwn]

The data channel is likely used for AVL, OTAP, and OTAR. It may also be used for Call Alerts and Status Messages.

 

[gary123]

Here are two more
site 3 - 142.815
site 4 - 142.515

Although these data frequencies now appear to be fixed use I have checked through my records and see that at one time they were used as voice frequencies.

 

[icarus1963]

Here are a couple of more for the list
site 11- 142.875
site 32 -141.555

 

[IdleMonitor]

New sites:

SysID AD9h-001
Mt. St. Patrick - 141.555 Ctrl. Ch.
Site 82
NAC AD2

I am able to confirm site 61 as Kinburn. Kinburn 142.215 has a NAC of AD1.
I'm sure there's more spots around eastern Ontario that will be seeing some changes happening.

 

[webstar22]

In Pembroke on 142.7100

And the numbers line up. 82 is St. Pats, 61 is Kinburn, we think 79 is Barry's Bay

71 or 79 could be Barrys Bay as both have frequencies that were associated with the FleetNet tower.
Site 76 142.665 looks like a new frequency for the area.

 

[Aviator747]

Things are definitely moving East. I am faintly getting Winchester.

 

[Aviator747]

More Winchester. There seems to be an extra frequency as well.

 

[Aviator747]

Vankleek Hill is getting in on the action as well. I think they are the Eastern most site?






Definitely looks like it. I am seeing activity on Winchester and Vankleek Hill.

About an hour ago picked this up on the Morton Tower/Fleetnet. I believe this is info for new Ont.

Cobourg is now officially connected to Whitby. No longer isolated, and has a new CC frequency.

 

[gary123]

One more data channel found: Site 10 - 142.155

 

[thecanadiangod]

Ottawa lost two FleetNet frequencies over night. No CC on those though.
