Anyone in the Brick area listening to Ocean Medical Center Security, the license in the database is expired. It looks like they may have gone to DMR… but it looks like they maybe using the same freqs under the new license listed on the FCC site.

I’ll try one more time, anyone listening to the Ocean Medical Center (Brick), Security… I haven’t setup a DMR system, having trouble… I’m trying it with the new frequencies that are listed on the FCC site for there update license, anyone have the system running? If not I’ll keep fooling, color code and LCN are required I think, am I correct with that statement, and having trouble finding them… The Analyze and LCN functions aren’t helping…

if no luck I’ll just forget that system… lol

I might be down in the area next week, so I'll see what I can find while I'm there.

Thanks, any help would be appreciated… I’m lost trying to figure this out. Database entries say license expired, looks like a couple of frequencies have changed according to the FCC.

Had a chance to be in the area for an hour earlier today while at work, and this is what I was able to capture:

DMR digital mode
461.5750 CC: 3 TG: 1001 SL: 1

I didn't have a chance to monitor the communications since I was on a phone call with work, so I'm not sure what they were talking about. Perhaps some listeners in the local area could tune that info in and see what comes about before a database submission is made.

Thanks… Not getting anything, I programmed it as a single freg DRM system, and conventional and I’m not getting anything, I just may not be hearing the system. I’ll keep fooling… been fooling with scanners for many years and this DMR has me baffle.

Well, I’ve tried everything, signal strength is ok, I’m just stumped, actually don’t know where to start with programming a DMR system. I tried what was given, and listened for at least 3 hours, not a peep. I’m just hoping someone with that kind of system experience can help me out. I interested in Security only, part of the problem is I can’t figure out how to program it, what type of system, conventional, one frequency, or single site, I’m lost… I have the SDS 200 uniden scanner.

You may want to search up above all forums. RAS. That might be one clue.
It it possible the system is encrypted? Check YouTube for programming DMR.
Also be sure to check your squelch. It should be low or loose not tight.

Good Luck!

I checked youtube, also searched forums. Let me start from the beginning.

Ocean Medical Center in Brick NJ in the database that license is expired, I searched on the fcc site and they have a new license, with a few different frequencies then the old license, I checked the emissions and I think it’s a DMR system. I have no clue what type of system to enter it as or what the real frequencies they are using. I tried the old and new and nothing, the LCN and color codes are another story, I’m just lost.

i was hoping to listen to security, family member works in that hospital, and last week another hospital in the area had a bomb threat in the ER, so i was hoping I’d be able to monitor Brick to to keep on top of any problems that may arise.

If I can’t figure it out I’ll just forget it and keep an eye on the database maybe someone who monitors the hospital will update the database In the future.

Thanks for your reply…

I wonder if the problem is that the DMR channel(s) is/are encrypted. GM -- what device did you use to capture that data, would it have filtered out encrypted comms?

The SDS100 & SDS200 remain muted for DMR encrypted transmissions, as best I can tell it gives no good indication of the transmission. So I suggest, to troubleshoot it, program two channels side-by-side:
  • frequency 461.575, modulation Auto, audio option Digital / DMR Color Code 3.
  • frequency 461.575, modulation Auto, audio option Analog, CTCSS/DCS Search.
The CTCSS/DCS search forces the scanner to open up for encrypted DMR comms (it won't decode them or display any color code/ talkgroup/ userid). You can Google for the DMR sound through an analog receiver to know what to listen for -- if you get it strong on the analog channel but nothing on digital then it may be encrypted.

I'm not a DMR expert by any stretch but some DMR channels/systems put out what I'll call here a sync message at a regular interval. The SDS will not open up for this in digital or auto mode but will play the noise in analog mode. When I've heard it the sync is about 4s with 60s quiet between. So you can look for a pattern like that if you hear relatively short bursts.

If you do get audio through the digital channel programmed above then you can delete the analog one and start paying attention to other data, especially TGID under the channel name and system type (DMR or CAP+ being common) near the top. That may give you more information for more-advanced programming which may allow you to listen to some users on that frequency and to ignore others.

Good luck.

I had the Whistler TRX-1 programmed for both analog and DMR in two separate channels, for all listed frequencies in the licenses. I also used a Pro-106 in Signal Stalker mode while sitting in the Hospital lot for the limited time that I was there. The transmission I heard was in the clear, but I don't know what they were talking about as I was on the phone at the time.

Regarding encryption on DMR, the SDS will generally mute it. The TRX-1 has the option of passing encrypted noise or muting the encryption. I opt for passing the noise so I can tell if the transmissions are in the clear or encrypted.

On the topic of the DMR data burst, the SDS nor the TRX-1 will open squelch for it. However, that data burst is very useful as it sends out the Color Code used for that frequency. Using this information, you can then program any DMR capable scanner with the specific Color Code that was sent out in the data burst to select only that specific agency using the repeater. If multiple agencies are using the same frequency in the area, but with different Color Codes, the DMR scanner will filter out the other repeaters in the same fashion that CTCSS/DCS tones are used for analog frequencies. The way that I would get the Color Code being broadcasted is using a scanner with a Discriminator tap, along with DSD+ software programming on my laptop.

I might be back in that area this week, but unsure yet as I have some tasks at work to take care of during my travels. Best time to monitor Hospital Security is normally from 6-11 am when operations for the facility are gearing up for the day.

The raw audio (not decoded in analog mode) that you would hear on a DMR repeater sounds like this: http://www.w2sjw.com/sounds/DMR_TDMA.mp3

The raw audio that you would hear on DMR in simplex mode sounds like this: http://www.w2sjw.com/sounds/DMR_FDMA_Simplex.mp3

When you say both analog and DMR, analog I get, what type of system did you program the DMR frequencies, as a conventional channels or single site, etc., that‘s where I get lost trying to figure what type of system to choose to program the DMR channels. Some let you add the SL, others don’t. Users talk about DMR, Cap+, it’s Greek to me.

I’d like to thank you for your and anyone else trying to help me. About 10 years ago I was very active in the scanner world, family member needed my attention (caretaker) so I was out of the loop. I’m 77 now and don’t grasp it like I did when I was younger. I’ve helped many to get their scanners up and running, co-authored the Win 500 software guide (on Utah Wiki) with a Vietnam buddy from Utah, who has since passed.

Once again, Thanks!

On the SDS200 scanner, it will have to be programmed as System Type: DMR One Frequency. As you build the system in Sentinel, you will have to program in the frequency with Color Code in the Site section, and the Talkgroup and Slot number in the Department section, under Channels. And in order to access these sub-sections, you'll have to create the System, Site, and Department first, then click on both sections on the left side in Sentinel programming, and then be able to add it on the screen. It's confusing, I agree but that's how they have it written for programming purposes.

Ok, I’ll try DMR one freguency tomorrow, wife wants to watch the debate… lol

Thank You…

To start with you can also program as conventional with digital audio, cc 3, as I had suggested. Then it will open for any unencrypted DMR transmission using color code 3 regardless of TGID and slot. If that works you can start paying attention to the TGID and slot and, if you want to monitor some but not others, you can reprogram it as DMR One-Frequency. If you skip right to programming it as a single-channel DMR system, you should consider whether or not to turn on ID Search in the system options.

I tend to choose Any Slot because I've found some issues where the SDS shows it as a new channel but really it's a TGID I already have saved.

GM - my SDS usually (always?) shows the CC for data bursts on CAP+ systems, it's just the DMR One-Frequency where it frustratingly doesn't. I wish it also gave at least the CC for encrypted channels (TGID and UID too, if they aren't encrypted themselves).

I just ordered a SDS100 to take to work with me,I’ll see what I can get. I’ll also see what I can get for Monmouth Medical Center Southern Campus.

Well, since my first post I’ve tried all the suggestions, nothing, I can’t even get conventional programmed as digital to show anything, stops on conventional while scanning but no audio. I’ve tried cc search.

So with that I got to stop a while, never thought I’d be defeated, but always a first time for everything. Lmao

Thank you everyone for your suggestions… time for a couple of beers!
