Montclair pd

[SCPD]

Back on P25 Trunked?

So they switched back to their P25 system. So noted in the DB. Fire Ch 2 also now lists in the description. (Back up for Police Dispatch). If they switch back and forth its covered!

 

[BIODTL1997]

Hey Ken are you doing the DB updates? One minor correction should probably be made for the fundamentalists out there; the MTC system is actually a type II system, not P25. EMS and PD are P25 voice modulated but the DPW and parking authority talkgroups are analog.

Contractors from Pinnacle were up at the tower today working.

 

[BIODTL1997]

And backup is one word. In this context, and with the rate of failure with their radios, "back up" is very confusing.

don't hate the playa, hate the game!

Biodtl1997,

OK, corrected to backup - one word.

Here is the info taken from the DB, what needs to be changed?

System Name:Montclair Township
Location:Montclair, NJ County:Essex
System Type:Motorola Type II Smartnet
System Voice:Analog and APCO-25 Common Air Interface

Some talk-groups are marked D digital, some A analog and some are blank ? -need info then.

Last night I heard the PD still operating on FD 2. So I don't know if they are switching back and forth from the TRS.

 

[BIODTL1997]

there were on FD2 again until after midnight when the repeater had another stroke and keyed up with a deadly buzz for at least 2 min. You could hear the units trying to talk over the noise, then it stopped and they switched BACK over to the TRS. I think it's time to start from scratch, which is hopefully what is being discussed.

And Ken, you're good, DB's good. I just read P25 system, and just was correcting that it is not in fact a P25 "syetem" but a tII with digital voice.

I have been monitoring also. Yes they have been switching back and forth. However, when I have monitored, they have been using FD 2 only very briefly before switching back.
Best bet is to monitor both.

Anyone slap this system into unitrunker? I've got a couple questions:

Disclaimer: I am a unitrunker NEWB. If I'm just an A$$ that didn't do my due research before asking these questions, shame on me.

Firstly, unitrunker is reporting that there are 9 channels in the system, however only 5 are in the DB, and I have never missed anything with these 5 channels programmed only as conventional scan. LCNs are as follows:

262
274
286
320
642
644
654
666
700

Also, I'm finding a whole bunch of target IDs other than talkgroups that are listed in the RR DB, although it seems that I am hearing all of the traffic while listening in parallel. It seems that a lot of these IDs are radio IDs, but the transmission is broadcasted on the talkgroup, so why the specific radio ID OR another ID that is other than the actual talkgroup that they are transmitting on?

Here are the target IDs:

32816 (known PD dispatch TG)
32880 (known MVAU TG)

32819
32841
32830
65536
32933
32973
32958
32937
32869
21811
32935
32840

Thanks for reading

They're back on the TRS for now, btw.

 

[SCPD]

65536 is fake ID for reporting CW ID.

As for the extra channels, check the hit counts. They may have channels held in reserve only used when the system is busy.

 

[BIODTL1997]

Thanks -- 65536 makes sense.

Hit counts on all channels are pretty significant, and across the board regardless of time of day or activity level.

I wonder if these 4 channels are VHF, used by their portables/VRS somehow...

262
274
286
320

This is the bandplan according to the DB so the above lower channels or "offsets" make me suspicious.


Base Spacing Offset
500.00000 12.5 380
506.00000 12.5 570

Montclair PD is back on FD2 - 500.4325 PL 192.8

reason unknown, just turned on my radio.

 

[ansky]

I have been listening to Montclair PD on the Montclair TRS, and I noticed every once in a while there is what sounds like a grinding noise when they transmit. It only happens occasionally. Is this encryption that they presumably turn on and off as needed?

 

[Markscan]

I think they are still simulcasting so that may be what that is. They have not used much encryption so far.

[BIODTL1997]

Has anyone ever heard any activity on the 700MHz TAC frequency listed in the DB? I dont think I've heard anything on it since I programmed it in over a year ago. If this is not accurate, what is the correct frequency?

I seem to hear much more activity from them on the Montclair TRS than on the NJICS. Maybe only some transmissions are simulcasted.

 

[Markscan]

I think only PD is simulcasting so the ambulance unit can still talk to them if needed. I think the holdup for the MVAU is money, but they want to make the switch.

Does anyone know if Montclair FD uses the township TRS at all? I heard a dispatch earlier today but only heard it on 500.3625, and when I switched over to the TRS I didn't hear anything.

 

[BIODTL1997]

No they use their pair of analog channels only.

Montclair FD

Does anyone know why Montclair Fire sounds so bad on 500.3625? I live literally on the Montclair border and their signal is constantly fading in and out, even with my outdoor antenna. Is it low power or just a bad radio system? From what I understand their repeater is on top of Mountainside Hospital which is no more than a mile or two from my house.

 

[railtrailbiker]

The transmitter site is actually just north of the Claridge House apartment complex, on the First Watchung Mountain. However, the height above ground is low - the antenna is mounted on a water tank that's about 2 stories tall.
