866.5375?

[mbstone99]

Picking up a strong Motorola carrier here in Burlington on 866.5375. Unfortuately I have no means of figuring out who it is atm as I am at work. I checked the RR Database for Ontario but there are no listings for anything close. There is a system out in Kingston and one in Sudbury but both EDACS. I checked the TAFL but nothing again for around here. I even checked neighbouring states New York, Ohio, Pennsylvania & Michigan and the only 2 systems that come back with a hit is a system down in Wayne County, Michigan and the statewide Ohio system. I have my 246T in control channel only mode but yet to hear any traffic or see any talkgroups pop up when I monitor the control channel.

It rings a bell but unfortunately my memory isn't that good these days.

IIRC, it's the 2nd Hamilton Wentworth Regional Police trunk system which isn't in the database.

System ID used to be the same as the regular system 4b1c but it had it's own control channel and voice channels.

The system was made up of 2 old conventional intelligence channels (astro) and a channel or two from the regular trunk system.

There was a handful of talkgroups on it but all traffic was encrypted.

It still causes problems as some people find the old channel listings for the regular trunk system, enter all the frequencies in, their scanner stops on the intelligence system control channel and then they get all upset that Hamilton has suddenly gone digital.

Of course, with my memory, this could all be wrong.

I was thinking that too but then again I have done 800 Mhz range searches over the past few months on the way to and from work and at my home in Ancaster but never hit anything other the usual, Hamilton's analog Motorola control, channel, Brant EDACS control channel, Haltons 3 EDACS control channel, sometimes on a good day Waterloo EDACS control channel. It's weird how all in a sudden if this is Hamilton other system that it popped back up out of nowhere. Oh and I am finally getting a single talkgroup that keeps on coming up active ever few minutes. The talkgroup of 112 is coming up but all I hear is the digital noise and nothing else.

Mike: Your memory is superb! I can remmeber sending a post here or the Yahoo group 'chicken littling' that Hamiltons system suddenly was unmonitorable.
It was back in 2003, the early spring and at the time you or one of the members set me straight.

It's fooled a lot of people. There's some really old frequency lists floating around that people seem to stumble across every so often.

I'll take a look and see if I can get any further frequencies for the system. I remember two conventional astro channels and 1 possibly two frequencies were borrowed from the trunk system.

It always surprised me that they used the same system id.

I'm out of town this weekend, Mike, but if you've had no luck figuring it out by Sunday I'll put trunker on it and get a sysid and as much other info as possible.

It's still in use, then? I've heard vague stories about this system before but I've not found the control channel or even really bothered to since the last I heard there was only encrypted communictations on it.

 

[jellotor]

I managed to find a few minutes this morning to stop in at my place and set trunker to work on that control channel. Here's what I've sussed so far...though it's only 10 minutes worth of decoding time.

SysID: 4B1C (same as Hamilton TRS in database)
Control channel: 866.5375
Alternate: 866.1625

Trunker claims that this is cell #1 of the Hamilton TRS (4B1C) and that the connect tone is 138.46 Hz.

As of the time I left, only 2 radio IDs were affiliated with the system and there were no talkgroups or patches assigned. Since there was no traffic I couldn't determine any voice frequencies right away, although trunker showed the control channel as a voice frequency as well.

Sorry to repeat some of my previous questions, but what was the original purpose for this system? Was it to provide coverage for H-W police in the outlying areas back in the day? I was getting a decode rate between 85-100% so I'm pretty sure that either the tower is located further away from me (I'm right downtown on Bay St.) or the ERP is lower than the regular TRS...which I never have any problem getting a 100% decode rate on.

Questions, questions, questions. Mike, if you can shed any light on this that would be great. I'll post any more info trunker gleans this morning.

I'm hesitant to submit any of this info here to the database until I have a better idea of which voice frequencies are on this cell. I'll also have to put trunker on the 'regular TRS' to determine if it has a cell number...something I figured I would have noticed by now if it was there.

As an aside question, can two Moto type 2 radio systems that are networked exist with both having the same SysID and only one acting as a cell? My reference point is Fleetnet, which has a cell number for each site unto itself, and when trunker is on a different control channel it of course creates a new file for each cell...and I don't recall seeing a file called 4b1cc1.txt until now...but I have been wrong before.

 

[mikewazowski]

These are two separate systems.

The regular analog 4b1c is a AMSS system while the digital 4b1c is a single site Smartzone Astro system.

The only users are the intelligence guys and I've never seen them unencrypted.

The intelligence guys started off with two conventional digital channels. At some point, these two channels and a couple of channels from the analog 4b1c were put together to form the digital 4b1c.

Not sure why they switched from conventional to trunked but perhaps they thought in the future, they could take over the analog 4b1c and add those channels to this system and move everybody over.

 

[jellotor]

Mike, thanks for the info. Once I've got some info from trunker I guess I'll submit it to the database.

Any idea why Moto would assign the same SysID to the two systems? I assume from your brief history lesson it's for possible future interoperability between the two systems.

And one other question, do you know where the tower site is?

 

[mikewazowski]

No, I'm not sure why they assigned the same id and no, I don't know where the tower site is.

What is the connect tone for the analog system? For some reason its not showing up in my trunker and is not listed in the DB

What is the connect tone for the analog system? For some reason its not showing up in my trunker and is not listed in the DB

Wow, anther old thread up from the dead for whatever reason.

The analog system was working fine today, I am in rexdale and I cannot monitor the system here but I will look at it when I get home.

BTW-Are you in the area today, your location says Middlesex London.
There is no way you are gonna hear this system from there.

 

[Muxlow]

Few nights ago i was able to connect to it but my signal was low

Hamilton PS Intelligence Trunk

Holy old thread comes back from the dead Batman!

Anyways I just looked and the connect tone is there there. http://www.radioreference.com/apps/db/?sid=4152

System ID Connect Tone
4b1c 138.46

You won't be able to hear anything on this system anyways as everything is encrypted.

[Muxlow]

I didnt mean for that system. Thats why i asked about the analog one not the other. Odd system

 

[slicerwizard]

The connect tone is 138.46 Hz. Why the hell did you revive this old thread?

 

[Muxlow]

Did feel like making a whole new one for one small question about the semi same system
...is that bad?

 

[slicerwizard]

Pretty sure it is.

 

[Muxlow]

Soo... then why wasnt this locked or moved or something?

 

[slicerwizard]

Because... most users don't dig up three year old threads and post to them? That would be my guess.
