NYPD Trunk?

[GTR8000]

They wouldn't. On systems that are partially encrypted, or part-time encrypted, my comment stands. However, one of the previous posters said that the talkgroup was previously in the clear, so there was an opportunity to identify RIDs before encryption.

The SIDs coming up so far are mostly techs, and come up on all talkgroups, so there's nothing to "identify" on this system.

But, if you had been following this thread, the only traffic is of the UHF system so there probably were no trunked system RIDs to be seen.

Yes, I heard it in the clear, then E

I swear, the more and more posts in this thread, the more brain cells I lose.....

Following known RIDs is the best way to identify encrypted talkgroups.

The only "known RIDs" on this system are the radio techs.....

True. Except, If you had been following this specific system or read the other messages in the thread, you would know that the only traffic on this system is multicasted from the UHF conv counterparts. On this system, specifically when multicasted traffic is heard, DSD+ (which I use) displays an EXTERNAL RID for each transmission, regardless of whether it's a dispatcher or a field unit. Because it is a straight multicasted patch, units are natively operating on UHF, not this system.

However, one of the previous posters said that the talkgroup was previously in the clear, so there was an opportunity to identify RIDs before encryption.

Yes, I did mention that. But I heard the multicasted traffic and matched it with UHF audio to identify it, not through RIDs, because, as I mentioned, they all say EXTERNAL. The Talkgroup was clear and then went encrypted right before It was submitted.

Expecting people to actually read the content of posts in threads and not chime in with random generic advice? Ha, yous guys must be new around here!

TG 701 being multicasted from SSD CW1 now.

 

[GTR8000]

Yeah, but did you verify the RID's to be sure of the talkgroup identity?!?!?

Seriously, has anyone seen any actual system subscriber RIDs, other than the radio techs, on this system?

TG 701 being multicasted from SSD CW1 now.

Maybe just for testing right now? I have TG 308 as SSD 1 CW, although I haven't heard 308 since August and haven't been listening today.
Im assuming TGs 701-706 are the Radio Tech talkgroups, But I can't be certain. Some are T, some are TE, and Some are Te.

Negative

 

[seagravebuff60]

Yep, I heard it again today. TG 701 was multicasted with SSD CW 1.

Been a while since the last comment. But I'm going to be across the river in Jersey next weekend. Should I bother programming this system? Sounds like the only reason would be to listen to SI in the clear..

From what I can see the system has been totally inactive for quite a while with nothing being broadcast.

No more SI ....

Anybody seeing any activity?

 

[pro106import]

Yeah as richie said, its been all but inactive for a few weeks. I heard Transit CW pop up a couple of times the other day when I put it back into the scan list. I have since taken it back out due to inactivity.

My guess, only radio shop guys have radios that can affiliate with the system. If they aren’t listening you’re not gonna hear anything. I have my own thoughts of what they are doing with this but I’ll save it till I know more.

 

[seagravebuff60]

I agree. This was my guess as well. Only radio tech/shop guys have radios to affiliate with this system, maybe a select few NYPD Brass. Say one of them switches their radio to listen to TG 1 - 1/5/7 Pcts; that is the only time you will hear traffic from that talkgroup. No Affiliations = No Traffic. The only affiliations are Radio Techs or very high NYPD brass.

I haven't monitored the system since maybe the summer (I don't know; my memory is terrible). However, it seems there is no known reason or method for what they do with this system. My guess is that when and if the system is completed, every NYPD conventional channel will be multicasted to it and mostly encrypted, mirroring what they are doing now with the conventional channels.

I wouldn't bother programming this system.
