Mark (NC5267) I clicked on that FCC Link which lead me to their 5 -150 watt listed freqs.
Real quick here is what I get from their tower out at 25870 US 281 North ....
1-856.0125 has Constant Data/MDT Sounding traffic
2-857.0125 has rapid burst, probably LTR Passport LCN
3-858.0125 has normal burst, probably LTR Standard LCN
4-859.0125 was quiet, no burst ... not a LTR HR LCN
5-860.0125 has normal burst, probably LTR Standard LCN

note: I have an LTR analyzer on 859.0125 to catch any hourly CW data
and will post LTR data on the other freqs 3 and 5 after I nail freq #4

OK, some small updates:

1-856.0125 As of now has Constant Data/MDT Sounding traffic, except when #4 had this traffic a day ago.
2-857.0125 has rapid burst, but there is NOT supposed to be any 800Mhz LTR Passport TRS's
3-858.0125 has normal burst, hourly CW ID's as LCN#3 without other peer LCN's
4-859.0125 now quiet, but 24 hrs ago this freq had the CC/data sounding traffic and #1 was quiet, hmm ?
5-860.0125 has normal burst, hourly CW ID's as LCN#5 without other peer LCN's

note: I have an LTR analyzer going and have not logged any talkgroups of voice traffic ....these seem idle ?

PS ~ These above freqs kinda remind me of these freqs listed at the same address below of 25,870 US 281N

APC.Comm NE Bexar Co LTR TRS (2004 old RR data)
6= 856.7875 Listed as LCN6 has Non-Burst with screwed/invalid CW data
7= 858.7875 Listed as LCN7 has LTR Burst of LCN7, only shows no peers
8= 859.7875 Listed as LCN8 has LTR Burst of LCB8 CW=shows no peers
9= 860.7875 Listed as LCN9 has LTR Burst of LCN9 CW=shows no peers

Making Good Progress on Communication Proffesionals LTD

Don't mind me for waking up an old thread that I recently ID'd after NC5267 originally nudged me over 4-1/2 years ago to start looking into this undocumented 800 Mhz LTR TRS. I do run a dedicated Pro-197 scanner programmed with just unidentified freqs and unidentified talkgroups to aid in my many investigations.
On Saturday 9/24/16 early in the morning I hear UNID TG 0-05-004 telling his dispatcher that he was just turning off IH-35N on to FM1103 and would be heading to the "Turning Stone" Cibolo sub-division to pour concrete foundations at multiple jobsites. The spirit moved me and I was out the door with gear in hand to finally solve these UNID TG's that I was meaning to get around to solving someday and now that someday was today :)
It was a cake walk because as I was enroute our very helpfull dispatcher calls Truck # 2179 for his location. Presto copy down street name and in short order I was onsite writing down the company info that was displayed on the Beck Ready Mix Companys Cement Truck. Heck it gets even better for me as on the trucks door was their logo and on either side read "Beck Readymix" and "Beck Disposal" Co complete with "Schertz, TX and their phone (210) 658-6321. As I was driving away our friendly driver keyed up and said truck "2179 to base" and that nailed my 3 scanners, 1 on close call, 1 on input freq and the other on TRS TG# 0-05-004. Next stop was on to their yard located at 550 FM78 in Schertz,TX. I got 2 birds with 1 stone as I drove past their address I see a row of yellow pullaway dumpsters labeled Beck Disposal and Landfill Co also displaying 658-6321 and several dozen White Cement Trucks just like I saw on one of their jobsites. Pretty darn big operation as their yard was "YUGE" as The Donald would say. I counted give or take 50 ish or more trucks and several acres of landfill on their property. Their other TG#0-05-005 keyed up about dumpster numbers and also lit up my 3 scanners to confirm. I was impressed that both their HQ yard dispatchers base radio and their trucks make the far away Communication Professional LTR TRS located way out at 25870 US 281 North ( right next door to the Beefeys Backyard Burgers ). Well having a big radio tower up at an elevation of 374 ft and 150 watts output power can do wonders for wide area coverage right!

I submitted the following data info 9/24 to the RRDB and it just got finally posted on 10/06/16 ...

Business Talkgroups:
0-05-004 A BeckReadyMix - Beck Readymix Concrete Co Business
0-05-005 A BeckDisposal - Beck Disposal and Landfill Co Business

-----------------------------------------------------------------------------------------------------------------------------

As I am solving the LTR side our friend "Dark_Side" had just submitted the DMR Connect Plus Turbo portion
of the mysterious mixed bag of 800 Mhz Communication Professionals LTD frequencies.

FCC Callsign WPQA748 (COMMUNICATION PROFESSIONALS LTD)
856.01250 = DMR LCN=1 LSN=1/2 Alt CC
857.01250 = maybe LTR LCN=2 ?(No CWID or LTR Burst) I will nail this sucker down if it kills me !
858.01250 = maybe LTR LCN=8 ?(No CWID or LTR Burst) (or DMR LCN=2 LSN=3/4) perhaps a dual LTR/DMR network controller ?
859.01250 = DMR LCN=3 LSN=5/6 CC
860.01250 = LTR LCN=5 HR CWID LCN=5 Free=2,8 Map w/LTR Standard Data Burst (10-second)

Communication Professionals LTR TRS : Communication Professionals (LTR) Trunking System, San Antonio, Texas - Scanner Frequencies
CP LTD 800 LTR TRS Business Talkgroups:
0-05-004 A BeckReadyMix - Beck Readymix Concrete Co Business
0-05-005 A BeckDisposal - Beck Disposal and Landfill Co Business

Communication Professionals (Connect Plus) : Communication Professionals (Connect Plus) Trunking System, Various, Texas - Scanner Frequencies
CP LTD 800 DMR TRS Talkgroups:
5020 T Acadian 1 - Acadian Ambulance Ch. 1 EMS - EMS Dispatch
5030 T Acadian 2 - Acadian Ambulance Ch. 2 BCFA/MED-COM (BCFA Contract) - EMS Dispatch
5040 T Acadian 3 - Acadian Ambulance Ch. 3 Medical - EMS Dispatch

ps~I will have to go back onsite and sniff out something other than their LTR HR input freq of 815.0125
Or up 281N and wait for both Beck TG's to talk simultaneously to nail down for sure LCN#2 & LCN#8
So since this event occurs mostly weekdays between 5am and 7am it will prove a tad challenging :(
Any help from the local few usual suspects that solve everything would be GREatly appreciated ;)
