New (?) P25 trunked system unknown location 855.0625 cc

nd5y · Apr 24, 2015

Good band opening tonight. I'm picking up a P25 control channel on 855.0625.
Unknown location. It appears to be coming from the E or SE of Wichita Falls. I can't find the System ID in the db. No traffic on it.

WACN BEE08
System ID 901
Site 001-001
Site NAC 901
No neighbors
Pri CC 855.0625
Alt CC 857.8625

I can also confirm this system is online from Collin county. Other than the details you gave, it's C4FM modulated.

Code:

====== NAC 0x901 ====== TPI ======
rf: syid 901 rfid 1 stid 1 frequency 855.062500 uplink 810.062500

ID: 1 frequency: 851.006250 step 0.006250 offset -45.000000

I did some digging on the FCC ULS search and found the source. It's a company called "Telecommunication Properties, Inc.". Go to the ULS Advanced License Search and enter 0009773607 for the FRN. I found the two frequencies seen on this system on two different call signs. Those being WQLP513 and WPEG623

I did a Google search for this company and came across this dated April 22, 2015.

FOR IMMEDIATE RELEASE: WJS-Dallas, Texas

Telecommunication Properties, Inc. "TPI" received regulatory approval from the Federal Communication Commission for an 800 MHZ P25 Phase 2 overlay network for North Texas.

Governments are no longer required to buy, build, own, and operate costly P25 radio networks in-house. TPI's 800 MHZ Carrier Hosted P25 service has demonstrated and proven to be more reliable, more scalable, more interoperable, more secure and more affordable than government owned P25 systems. Specifically the FCC approved TPI to build, own and operate a multi-channel wide area 800 MHZ P25 overlay network.

I can hear this system all the way out in Allen. I have profound reservations regarding the vision/practicality of such a system as proposed by TPI (in the linked article). The largest roadblock by far in Dallas has been the staunch unwillingness of police agencies to share systems. Everybody has traditionally wanted to control their own domain. Further, we have regional systems already in place that these guys simply do not use. NCTCOG covers all of DFW and you rarely hear anything on it. The VHF InterOp channels are beginning to see some use outside of DFW, but within the Dallas the telephone and simply programming their radios with neighbor systems are the primary interOp methods in use. Several systems are already P25 or have already bought into P25 (City of Dallas and the northern 'burbs) so I don't see them joining TPI's system. There is a possibility that they are targeting the smaller departments with wide area coverage and modern features but the price point will have to extremely low as these agencies already put very little into their radio systems. Lastly, channel availability is going to be an issue as 800 MHz licenses are getting harder to come by, especially wide area channels - there will be tons of bonks - not good for public safety. I do see several license in the 900 MHz range also owned by TPI, however, I assume those are for commercial users. It's gonna be a pretty tough row to hoe on the Dallas side and impossible on the Fort Worth side with their new regional system. This will definitely be interesting. ISSI certainly creates some very interesting possibilities for all P25 systems.

I've logged some voice traffic on this system in the past 24 hours. There are no secondary control channels listed as of now.

These frequencies are spread across four different call signs. Those are WQLP513, WPEG623, WQSB403, WKM78.

Four frequencies haven't yet been logged: 855.31250, 855.78750, 858.86250, and 860.28750.

This looks like an SMR. Check out this FRN ...

Callsigns for FCC FRN: 0004745493 (CHILES, JAMES T)

Looks like Telecommunication Properties Inc. Check out http://www.tpidas.com/ and click on the Projects tab - very interesting.

I see where PiccoIntegra already found the TPI info, especially the press release. That's what I get for not re-reading the entire thread. I do find it interesting that they are proposing a wide area P25 Phase II for Public Safety use. I would think it would take a lot more channels. Fort Worth Regional and the NCTCOG Overlay would also seem to put a dent in the business model.

PiccoIntegra · Jan 19, 2016

Late last night I heard what I thought was a DPS transmission. What I heard was "DPS CID" on TG 50, but there were no replies. Based on that, I assume that this person was on the wrong system. I have seen encrypted traffic on that same talk group.

Then again this morning, I heard talk about Ft Worth and "TMS" sites and radios being programmed correctly. I wasn't in front of the radio to catch the talk group though.

I wasn't sure how you'd enter the data I posted into the DB, which is why it's in this thread. There are no neighboring sites, no secondary control channels, no BSI information, just the voice grants above.

There was traffic on that same TGID this evening, a long discussion of whether or not they could make use of the helicopter. No unit #s were mentioned (I walked into the room where that system is on one of the scanners after, apparently, the discussion had been ongoing for a while).

PiccoIntegra · Jan 20, 2016

Just now heard the DPS heli pilot(I recognize his voice) talking to someone about equipment not working correctly. Talkgroup 50 is definitely DPS related...

edit; They're referring to the TG as "AOB".

The DPS pilot does have a recognizable voice.

AOB- "Aircraft Operations Backup"??

Russell · Jan 20, 2016

I was thinking "Aircraft Operations Base" ??

FYI ... I hear DPS 101 and Dallas Air 1 chatting on air to air (AM) occasionally.

PiccoIntegra · Jan 20, 2016

It's likely Base as they were talking about the hanger as well. It is weird they're on this system though...

PiccoIntegra · Jan 21, 2016

I think the correct channel is "DPS AOD". I've heard this twice this evening, both crystal clear transmissions.

Next time that talkgroup is active somebody should check to see if it is patched to their VHF air channel 156.2175 NAC 162 or 159.09 or 155.505.

This system is also advertising as Phase I on the Control Channel.

This morning I found a couple 900 MHz DMR Connect Plus control channels on frequencies that appear to be licensed to TPI's owner. (see http://forums.radioreference.com/texas-radio-discussion-forum/333693-texas-dmr-3.html#post2589932) Then I found that the tpicom.com url is now redirected to Extenetnewsreleases_20160511.
