LMRN Technical Data Discussion

Yep, seen them hop on, do a radio check, test Emergency button, acknowledge and move onto the next one. Noted it during a series of many radios being checked over a few days.

I saw that one radio, 100025 was in the clear. Of course, I wasnt home to hear what they were saying..

Someones radio must have a crappy signal because all day long today my screen has been filled with registration login from the same radio id on the same talkgroup. I figured it's just a junk signal and comes in and out, and keeps affiliating
Damn things gotta have over 70 affiliations since 8am today, every few minutes

I've logged that one out off Whitby. The 1000xx series radios all seemed to be radio site checks from what I had logged. They usually were checking out locations for coverage. It sounded like sometimes they would test with encryption and without when doing checks. I've logged 4 IDs in that range.

 

[Muxlow]

Just had radio 214010 join group 2506. I don't have either of them in my list for any sites

 

[Enjoi19]

Lots of chatter this morning on a new talkgroup for me, 697, with 600xxx and 502xxx series RIDs which I haven't seen much (or any) of either. Fresh key ID compared to previous encrypted calls I've logged.

 

[Muxlow]

Since 697 seems to be the radio test group and this one being 1 digit off.. perhaps its another testing group? Perhaps for the comm centers to do testing? Total guess here by the 600028 radio.

Starting at 21:00:01 tonight, my Trunk-Recorder system on Fleetnet Site 27 (Fenelon Falls) lost the usual control channel signal.

I'll skip over the diagnosing/troubleshooting time while I was trying to figure out why trunk recorder was apparently broken.
Oddly, my Uniden SDS200 was very very quiet also, so I had a clue that something else had just occured.

I decided to reconfigure Trunk Recorder for P25/QPSK instead of Smartnet/FSK.
This is what I see. Unless I'm dreaming, Fenelon just became site 058 in PSRN tonight, about 9pm local.

Writing again just after Midnight. Fenelon Site now seems to be off the air completely.
I used GQRX and scanned the spectrum for any control channels that I can receive.
142.170 - Decodes as P25 Site 038, which corresponds to LMRN Pontypool. (South of me 20 miles)
142.590 - Decodes as Smartnet, and has 2OPS35 traffic for Bancroft, corresponds to Fleetnet Zone 2 Harcourt/Haliburton site.

Looking at my logs, between 11:07pm and 11:09pm, while I had Trunk Recorder in P25 mode, I see two P25 digital-TDMA transmissions on TG 1025, Source ID 100015, Clear audio, which was some sort of test transmission with a person counting numbers up.
142.185 is usually associate with Fenelon site.

}

And as of 01:05am, Fenelon is back to Smartnet with the control channel on 142.605.
There was a few minutes of control channel with no calls, and then the usual FleetNet TGIDs and voice calls were back live again.

Been getting a lot of these the last couple weeks. It's always the same freq as the others that are in service on the old system, Oxford Tower (21).

 

[mikewazowski]

Looking at my logs, between 11:07pm and 11:09pm, while I had Trunk Recorder in P25 mode, I see two P25 digital-TDMA transmissions on TG 1025, Source ID 100015, Clear audio, which was some sort of test transmission with a person counting numbers up.

Checked my logs and I see a Registration, Affiliation to Group 1025 and then a Deregistration on the Edgar site from that ID just before 9pm. Log shows no other traces of Group 1025 or that RID except those 3 events.

 

[32dave]

They just told the MTO in Oxford to switch to the new system Here is a screen grab of them testing it about 20 mins before being told to switch.

 

[Forts]

I'm seeing this off the Byron tower as well. I've seen testing recently on 2006 and 2011.

 

[Forts]

2011 has units calling XJF445 London.

 

[32dave]

I believe Talk Group 2012 is Woodstock MTO

 

[gary123]

Last night heard 2021 off site 45(Monro). Perth West with road patrols 21-29
today heard them on Group 2020 again on Site 45. Last night they may have been on the wrong TG??

I am also seeing some of the neighbor lists have changed. So those who can should reverify the current list.

Site 33(Tavistock) is on air but not active no neighbors although site 45 and 4(Listowel) have it in their list.

Site 4 = 3,8,12,25,33,36,44,45
Site 12 = 3,4,5,9,23
Site 45 = 4,18,21,25,27,33,36

 

[ve3tej]

Patrol 15 radio id 200249 was on talkgroup 2015

London is definitely 2011 and is Patrol 11
Woodstock is definitely 2012 Patrol 12

Last night heard 2021 off site 45(Monro). Perth West with road patrols 21-29
today heard them on Group 2020 again on Site 45. Last night they may have been on the wrong TG??

They were more than likely patched.

 

[mikewazowski]

MTO was the first to switch over to Fleetnet when it came online. Looks like they're doing it again.

 

[gary123]

Time to start logging RIDs and the TG they are on.
