Which rid range? 14XXXXXX (9 digit) , 771xxxx (7 digit) or the 1XXXX (5 digit) ?
Anyone noticed the NYSP, NYSPP and NYSDEC radios with 9 digits are tx'ing OTA aliases on F63?

That's ok; I understand now. Just took me a minute after u posted. SP is "Special Post"; usually, the district is first like "11 SP 1" or "11 Special Post 2". I don't have any hits on that TG for the Zone 2 and 3 Simulcast.

Ok, rid comes back to District 5, they are saying 5 SP 1 & 2 and calling it tac 2, guess I can make a submission shortly.
Was receiving this on Zone 1.
I think the 14xxxxxxx is the new NYSP range on the F63 System.
I didn't notice it before now. Good find.

In my previous post, I meant to write 8 digit rids, not 9.
Tg 5012 is suspected NYSP. (Troop L) On F63, rid's are 8 digit and on 26E the ones that come thru are 5 digit.
Not sure where Troop L went. 5011 not used in a few days now.

Just curious, how exactly does a rid appear differently on each site?
Im getting NYSP Portable Aliases on TG 5012 on the F63 System. Perhaps they are in the process of moving over to that TG?

F63 is/was metro (26D) and has had tg’s for long time as well as on 26E. Also have tg’s on Suffolk and East Hampton trs and most likely on Nassau as well.
F63 is the new Metro Cell, replacing 26D. The frequencies are the same. Most TGs remained the same; however, some have changed, like NYC DEC PD. A lot of Radio IDs have changed as well. Im not sure exactly why the change, but it's there.
I haven't seen the agencies in person since the update, but if I had to take a guess they probably took all of the Metro-25 APX8000s and replaced them with XL200Ps.

On 26E Z1, most of the NYSP radios I saw on New York State Police tg's were 77xxxxx. Not seeing any of those on F63 and only a handful on 26E Z1. And any state radios with aliases are only displaying them on F63.
Thinking outloud here, and someone, please correct me if I'm wrong, but aren't OTA Aliases "proprietary" and outside of the P25 standard still? Or has it been added? Furthermore, again, just thinking out loud with no actual monitoring of the system in question, but I believe over the years, NYSP appears to have moved away from Harris subscribers and onto Motorola portables and even Kenwood mobiles. Could it be possible that the F63 cell is Motorola and implementing a Motorola cell brought out the OTA Aliases? Looking at NYSP's recent Facebook photos, I can't find a single Harris portable on any Trooper, especially on the photos and videos of them in the NYC area. There are just lots of APXs.

I remember hearing techs from EF Johnson back in 2023
Site still saying Harris but who knows if accurate. I mean date in clock says 1999.

I remember hearing a week or two after the F63 cell came to light that on the Metro North Fire Brigade TG there was a conversation about problems with the update and someone said "Harris is going to be here in a few hours", then later on I heard "The techs from Harris are here (at GCT), can someone escort them?" Metro North was also using APX8000s, not that any of that definitively means anything.
Yes and no. DMR and NXDN also have that feature (or whatever their name for it is). As far as I can remember, DSD+ has always decoded the talker alias for them for at least the last three years. DSD+ has also supported decoding Harris P25 talker aliases for as long as I know. In the past six months or so, DSD+ added support for Motorola P25 talker aliases. And other software eventually followed.
The way that talker aliases are transmitted over the air "internally " varies from manufacturer to manufacturer. For example, Harris OTAs are transmitted differently than Motorola Talker aliases. Yes, P25 is just a standard, but each manufacturer operates differently.
A few updates ago, it was easy to differentiate a Hariss transmitted OTA vs a Moto OTA transmitted in DSD+. I had not updated the recent version until today, when I was monitoring the system with OTAs; All of them looked like Harris Transmitted OTAs.

Would you happen to remember which version that was?
Yes. According to my log file, it was 2.506.
Yeah, I knew that DMR and NXDN had that feature for quite some time now. I'm seeing it implemented in DMR more recently, and NXDN, well, I felt like that feature has been implemented forever basically. I was unaware that the Harris talker alias was available in DSD for some time; I thought it was all just something new DSD added and not just an update for Motorola OTA aliases (since October, I believe when the "big" update came out).
I knew Harris and Motorola did them differently, and APCO was trying to come up with some standardization to implement it into the P25 standards, and BELIEVE Motorola wasn't on board with it for whatever reason.
I have yet to see Harris OTA's, as no one locally uses Harris with that feature enabled, so, I'm just looking at it from what I was reading others reporting and trying to come up with a possible reason for it all.
Just wanted to add a quick note to those monitoring the system with an SDS100.
