Keep in mind that if they are using LTE to access their TG instead of RF, you may not see the TG carried on any site unless something is actually affiliated via RF. I'm not saying that's the case here, but it is a possibility, generally speaking.
Ok since I am a major newbie, let me see what i got straight here (probably verry little)
They are part of the
They are part of the
Metro-25/MTA MRRS NYC Metro 25 simulcast, they are on talk group 9560 but they use LTE. How would do I configure that on my Uniden BCD325P2? |
You can add TG 9560 to your scanner, but if there is no radio affiliated with that talkgroup at any MRRS site, you're not going to hear anything.
Dobbs is definately on 9650 tonight.
But I am unclear how this works.. they have new p25 radios that affiliate with MRRS as their primary communication path? (doubtful) If so, why would a 2 square mile village sometimes affilate but mostly not?
Or do they connect to a local repeater over another means and the MRRS is just backup?
You mention LTE.. cellular? (the apx8000 radios in the purchase order listed above shows 4 band use but doesn't mention LTE that I could see, but admittedly I know nothing about those radios or LTE either. That would explain why no one receives any chatter? So cell with MRRS as backup? and again, why wouldn't every radio from such a small town affiliate with the MRRS sites full time? Clearly I do not understand any of this so perhaps someone can explain? Thanks...
I think we're getting a little ahead of ourselves here. We don't even know if this is a permanent thing, or if the MTA loaned them radios to demo the system. As for that purchase order, it's a year old and could've changed. Those radios were all spec'd for UHF, however the MRRS is a 700 MHz system, so only the APX 8000s on that quote would've potentially been capable of operating on that system.
Continue to monitor the talkgroup on the MRRS as well as their UHF frequencies, and see how it all shakes out.

I very much appreciate you looking into this. I live in Dobbs Ferry and the main reason I bought the new digital scanner was to pick up my local town PD. I think the LTE idea is on the right track. The office I spoke to did mention this connection was like a cell phone and now that I think of it, he did mention LTE. You jogged my memory. He told me they were trying the new system out since they were unhappy with their old arrangement. I got the impression he was not happy with this new arrangement either. Maybe they will divert back. I still scan their original frequencies and twice I heard a basic ID statement specifically stating Dobbs Ferry. FCC requirement
Something Interesting. (And remember iIam very new to the P25 talk groups. I had an old analog only scanner.)
I checked a different Database Web site and looked at all the frequencies for the Village of Dobbs Ferry.
At the very end of the list, they added "state" frequencies of 851.0375c 851.5375c 852.0375c 852.5375c 853.0375c
These are both the Metro-25 Simulcast and Grand Central Madison. So this is where they may be now? I program those in and so far I have heard
nothing at all. (I also have no idea how to configure a talkgroup)

The Metro-25 system and MRRS (aka MTA) system are essentially one big system. They could come up on either the MRRS Zone 3 cell, or the Metro-25 Simulcast cell, I suppose. But again, if they are using LTE capable radios, they may not come up on any RF resource.
I'm curious, where did you find that listing showing the Metro-25 frequencies?

Okay, I see what you're looking at now. Just be advised that list is a raw dump of FCC licenses, not any sort of user-verified list of frequencies actually in use.
That refers to WQED562, which was canceled way back in 2011. The purpose of that license was to put a Metro-21 EDACS site (the system that Metro-25 P25 replaced) at the Dobbs Ferry MTA station, so it's unrelated to whatever Dobbs Ferry PD is doing now...just coincidence.

I have the exact same question! Do I configure this as a P25 standard or Mot type II / P25 ? or possibly something else?

MRSS is a Harris Phase II trunking system, and the only time you will hear an agency other than MTA-PD who operates simulcast system wide is if a non MTA-PD unit affiliates with that local cell. If a units is using LTE you won't hear anything.
From when I was still with MNRR radio there were only five 700 mhz frequencies system wide, and I don't know if there is a way to monitor just a single frequency on both talk paths with a real radio or scanner.

The MRRS, as well as the interconnected Metro 25 system, have five frequencies per simulcast cell/zone, not five frequencies systemwide.
P25 Standard.
However, you may experience simulcast distortion issues with that scanner, as the system is simulcast.

Thanks for the info..... and Yes, it appears the BCD325p2 is having a simulcast issue....I am stuck on the "Finding Control Channel". Does anyone know if a new or better Antenna will fix this issue? or is this an issue of the scanner itself and cant be corrected? Thanks again.
In this area (near dobbs), on that system, using the bcd325p2 (or the bcde536hp) , I was never able to get past "finding control channel", and I tried many antennas (and none), or paper clips, external discone, duckies, nothing worked. But the sds100 fixed all that..it receives that system well, although my analog reception is not as good with the sds100 as with the bcd325 or bcd536hp.

Ugh…. I just got this scanner (bcd325p2) as a gift about a month ago, so I am stuck with it….. thanks for the help. Hopefully they don’t settle on this system!
