Fort Sill new P25 system

[nd5y]

It looks like Fort Sill P25 system is changing.
I found a "new" system this morning and didn't know where it was coming from. Details are here:

New(?) P25 system C51B0-03B

Band is open good this morning. I'm getting a CC on 385.025 WACN C51B0 SID 03B RFSS 5 SITE 5 NAC 005 No neighbors. It appears to be N or NE of Wichita Falls, TX. I don't know how far or what state. It looks like a Harris system with all freqs as CCs. Unitrunker picked up the callsign "1US AS?"

forums.radioreference.com

The new site 5-5 has the same frequencies as current/old site 1-1 Bald Ridge but different WACN, SID and NAC.
I didn't see any traffic on it. I think it just came on line in the past week or so.

Somebody in the Lawton area needs to search 380-390 MHz for P25 control channels and see if there are any more new ones that don't match with the current "old" system.
I think site 001-001 is gone.

Here is what I submitted this morning:

New US Army Fort Sill, OK system
Unknown if this is part of a larger multi-state system
(McAlester Army Ammunition Plant has the same WACN but different SID)

WACN C51B0
System ID 03B

Site 005-005 Bald Ridge?
Coodinates probably the same as the site with the same frequencies on the "old" system.
Lat 34.6924 Lon -98.3356

NAC 005

Harris system with all channels as alt CCs.
385.025
385.325
385.675
385.975
386.275
386.575
387.175
387.475
387.775
388.0875
388.3875
388.700
389.025
389.4375

385.025 has been active the past few days
These are the same channels as site 001-001 on the old system.
The sites on the old system are showing 385.675 as the CC for site 001-001
but I haven't been able to receive it.
I can't tell if that site is off the air and replaced with this one or
they moved it someplece where I can't receive it.

So far there has been no traffic at all but it shows some patch talkgroups
38052
38053
38054
38055
31159
31161
31300

The past couple days these were the talkgroup patches
61973 > 30855, 31313
61987 > 30854, 31300
62002 > 30852, 31159
62003 > 30853, 31161

Today they were gone and it was
62020 > 30852, 31191

Still no traffic or affiliations

The sites on the old system are showing 385.675 as the CC for site 001-001
but I haven't been able to receive it.

It's still on the air but too weak to decode.

This morning there are some active radios on the system.

RID ranges
590007xx
590008xx

Several data transmissions. Probably OTAR.

One phase I talkgroup 40510 had a few encrypted transmissions.

The only channels used so far where 385.025 (still the CC), 385.325 and 385.675.

Several patches are still active but I haven't seen any traffic on them.

I haven't noticed any changes on the old system but I haven't been able to decode all the sites for about a week.

 

[nd5y]

More RIDs in the 592xxxx and 593xxxx ranges and
TGs
40539
40699
40980
40994
affiliations but no traffic.

I haven't noticed any changes on the old system but I haven't been able to decode all the sites for about a week.

On the old system they removed or quit using several channels. I'm not sure exactly when.
I haven't had hits on some of them in over two years. This may not be a recent change.

These appear to be no longer used:

Site 1-1
385.025
385.325
385.675
385.975
387.775
389.025
389.4375
(7 active channels remaining)

Site 2-2
380.075
380.375
381.625
(3 active channels remaining)

Site 3-3
380.4125
(5 active channels remaining)

Site 4-4
no channels removed
(8 active channels remaining)
