MICCOM DMR Operations

[W2SJW]

I know it's been a couple of months, but I just wanted to update you guys that this system is a 7-site IPSC setup, and we've found 5 of the sites (most are noticed to be at properties owned by St Clare's:

• Oxford (Warren County)
• Hackettstown (Warren County)
• Randolph (Morris County - main site in the system, it appears)
• Denville (Morris County)
• Sunrise (Sussex County)

Anyone that can help finding the last 2 would be greatly appreciated. The sites should always be carrying MICCOM on slot #1 & Atlantic on slot #2, and it seems the 5 sites discovered already are sticking to CC8 & CC10, so that should help narrow it down...

So it seems that there are two sites (Denville and Dover) who rebroadcast the EMS talkgroups who also repeat hospital operations. You can hear the operator paging floors, security, maintenance etc.. I believe they have a TRBO system tied into their PBX/exchange. The talkgroups are 4000100 and 4000200 always on TS2.

I attached frequencies owned by Prime and my findings for St. Clares EMS. Some results contradict the FCC info in terms of signal strength. I also had a problem with other TRBO systems encroaching in on some of these frequencies from my location. The last 2 frequencies are duplicates but carry data/voice on a different color code.

I'll let you guys decide what to do with it.

I was told about the local in-hospital operations being on the system (that traffic is deliberately designed to not leave the campus coverage area).

I'll see in my travels if I can actually cross-confirm what you found here...

 

[NotATechGuy]

I live right between the two systems and my antenna is pretty high up so it might make sense why I'm picking them up. You can probably pick up Dover from parts of the the Rockaway Mall, not sure how far Denville reaches. I checked each frequency twice on that list before writing confirmed. I don't know if the two sites missing are indeed the hospital campus's or a newer tower to extend the system out. I wouldn't be surprised if one is up in Vernon but Sunrise seems to be a strong signal and a prime location.

I discounted that one 457 channel, as that's obviously a repeater input. The 464 Randolph channel has me confused, as someone already submitted 463.375 as Randolph a few weeks ago.

That's supposed to be the strongest site in the whole system. The re-use in the hospitals was planned, and the maintenance & ops TG's don't go out over the IP side of the network...

 

[NotATechGuy]

I cross-referenced the FCC license with my results. YMMV

I can confirm 464.225 as the main frequency for the Randolph site carrying the ALS traffic. I have it programmed both as a conventional DMR and a DMR One Frequency site and am receiving both AHS and MICCOM on the TG's and Slots in the database.

Not hearing anything on 463.375.

I'll have to take a ride and see if I hear anything on 452.025 in Denville or 452.300 in Dover.

Great! I find it hard to get over that way much during work & any other members willing to help narrow down the last sites is a great help!

OK, I've got the last few updated entered. We seem to be missing 1 more site. Hopefully I can figure out in the next week or so if 452.025 is a campus-only channel or a wide-area one...

 

[W2SJW]

I just had an epiphany this evening when I discovered you can create conventional networked DMR systems in the DB! I pulled the channels out of the respective separate county pages & moved the system here:
Spectrum Communications Trunking System, Randolph, New Jersey - Scanner Frequencies

I'm going to add links in each county's emergency services section to point to this tomorrow...

 

[rr60]

This frequency appears to be for the Morris & Warren areas, so anywhere else, YMMV.

463.850 - CC=8

MICCOM St. Clare's - TG 10005000 - TS1
Atlantic EMS - TG 16000000 - TS2
Hackettstown RMC EMS - TG 11002000 - TS2

I hear Atlantic units at Overlook, so I'm not sure if the channel is linked to other repeaters on other frequencies via IP SiteConnect, or if there are numerous sites on that specific frequency.

I have found another frequency in addition to some of the others on this thread. I suspect one is in Middlesex County. I maybe hearing two systems on same freq (different signal strengths). It appears as DSD on the 536. I will run DSD+ tomorrow.

It is using the same CC and TG's as above and sounds like same areas. I suspect it is a Part22 as I did a quick FCC looksee with negative results.

The frequency is 464.225 CC TG and T\S same as noted above by Scott.

 

[W2SJW]

That is the Randolph site you are hearing - the most powerful site in the whole system.

Thanks Scott! Save me some legwork. Back to Pirate Radio.

I see there is now a Chester site 463.375 (CC 8). What has me tilting my head is that the FCC license is listed as WNRE654 which is licensed for farming with an emissions designation of 11K2F3E. None of that matches anything in this system.

 

[W2SJW]

I was given that info last night from a trusted source. When working with business-band licenses, you are constantly going to find inconsistencies like this...

I left DSD+ open for 12 hours and got zero hits or data bursts. I live about 15 miles away on top of a hill with an antenna up about 40 feet. Maybe it's a very low power output repeater. Can anyone else confirm this frequency?

 

[Sybex7254]

The callsign for the Chester frequency is under the name of Alstede Farms which is in Chester.

WNRE654 (ALSTEDE, KURT) FCC Callsign Details

Doubtful its for MICOM/EMS and would explain the farming classification.

Well if that is it, it appears as if that license shows the site elevation at almost 900' MSL w 500 watts ERP yet no digital emissions and no AAT or AGL for the antenna. Odd.

 

[nosoup4u]

I can confirm the Chester site is part of Spectrum. I heard them loud and clear all the way on Route 78 in Warren Twp. and the talkgroup ID was consistent with the Spectrum talkgroup number plan.

 

[W2SJW]

Thank you! I was getting concerned about the data I was given! That person has been pretty reliable about other Morris County data...
