Updating Corpus Christi TX area systems ?

[rattlerbb01]

this system 303 band plan is something else but I think I have it pretty close. It is weird the jumping they did around and how the 454.xxx frequencies come after the 460's.

CH 001-321: 451.01250 - 453.01875 (cuts off at beginning of public safety pool), Steps .00625
CH 322-624: 460.65625 - 462.54375 (cuts off at beginning of FRS/GMRS/Paging/Medical), Steps .00625
CH 625-912: 463.20000 - 464.99375 (picks up at end of Medical pool) Steps .00625
CH 913-924: May not exist
CH 925-1004: 454.00000 - 454.98750 Steps .0125

This is mostly based off of my observations of the 451-452 frequencies being used as CC's and all the 454 Part 22 frequencies that are using the 900 channel IDs. I have yet to hear one of the 461-464 frequencies on the air personally so let me know if you hear one and what DSD+ reports it's channel ID as so I can fine tune the band plan.

 

[Michael-SATX]

Bob(ralexander5), you had originally reported that on the system303 site-3 George West - Live Oak Co
that you observed with DSD+ that the cc switched from 389-461.075c to alt cc channel 981- 464.425a.
Now today I see that Paul has edited CH ID-981 to be 454.7000a and no longer 464.425 - is this right ?
To quote that old game show line ... " Will the real CH ID # 981 please stand up " It can't be both freqs!

CH ID Frequency
389 461.075c
589 462.325
981 454.700a

 

[rattlerbb01]

Michael,

I heard 454.7000 as a faint CC from my hotel 4th floor in Cotulla. DSD+ reported site 3 switching to 981 at 00:56 before site 7 Cotulla switched at 00:59. I went ahead and changed it based off that but should we hear 981 as a 464, then we can change it back and begin to wonder how in the hell the band plan got jacked up that bad.

 

[ralexander5]

So let's clarify If I understand you correctly on your site #3 freqs and their role playing observed so far:
389=CC primary and VC, 589=VC Voice Only never been a CC, 981=CC secondary and VC (see below)

003 (3) George West Live Oak (389)461.075c (589)462.325v (981)464.4250a (already submitted like this)

I am currently monitoring 464.425 and it is being reported as channel 981 on site 303-3. I have had this site on for several days now and have only seen the 3 channels above active. I have also seen some activity on another frequency also reporting as channel 981 but I assumed it was an image. Not seeing anything else tonight. 454.700 has no signal.

On my site #1 12=CC primary and VC, 15=CC secondary and VC, 18=VC Voice only never been a CC
So our 2 sites differ in that only my 1st & 2nd freqs rotate being the CC and your 1st & 3rd rotate as CC
001 (1) North Central San Antonio Bexar (12)451.0875c,(15)451.10625a,(18) 451.125v

TG 801 - I first saw this new 3/8/18 Fri 6:30pm & 10:31pm with RID=810 with alias of (3C C4) meaning ?
TG 1904 - I have not seen or heard this TG so far.
TG 3901 - School Buses w/ RID-3901=(Bus23) and 3904=(Bus17) (maybe additional TG for KCISD use ?)

Web search shows 3C C4 as a holder of mineral rights or interest in some oil fields in LaSalle County.

Also seeing some aliases of Beeville?? and Alice?? but so far have not heard any identifiable communications.

ps ~ I can see another future blemish on Live Oak Countys squeaky clean RRDB page with the following:
New Trunking System Name: Industrial Communications (George West) - LTR Standard
LCN#?? 452.4625 (Hey at least it CWID's which should reveal it's LCN#? and if it's a HR Home Repeater)
Wildcard TG's Hit Counter=0 after a few weeks maybe its a dead horse or you may find a rare gem TG
FCC Lic WPSQ521 40W YG 451.300, 451.8375, 452.2125, 452.350. 452.4625 & 452.7500 (put em all)
So best tool would be one of your Pro-197's, manually setup a new LTR and add all 6 freqs on license
Make darn sure to check or enable "Auto Move" or LTR Auto Place feature and create a Wildcard TG etc.
During that hourly, bi-hourly CWID and or an active TG - your 197 will place 452.4625 in it's correct LCN#
I would start off by placing those 6 freqs from LCN#14 thru LCN#20 so that 1 thru 13 are wide open and
besides it will be much easier to notice say when all of a sudden 452.4625 becomes say LCN#2 example.
Sometimes depending on RX conditions you might manually sit on your newly created wildcard TG object
in this manually created LTR Standard TRS, press TSYS(F2), then press Analyz(F3), the scroll down to
the freq 452.4625 and just let it sit awaiting either an actuall active TG or usually a CWID or with our local
Industrial Communications LTR systems when the 7 sec idle data bursts hits the freqs LCN# is revealed
Next make sure that your Pro-197 Hit Count feature is enabled and heck even make the wildcard a FAV !
Also set a "Ring" alert with a flashing white LED mode tied to this new Wildcard TG to alert when active.
So set and forget it while you go to work and sleep. Then drill down once a day and check WC's hit count.
CWID's will not trip this count only new voice TG's and make sure if your right there to hit Store & label it.

I set this system up to record in Proscan and caught TG 0-01-023 on 451.3000. I was about to call it dead but I will now see if I can get the 197 to report more.

Lastly, I saw these 100w freqs licensed to Corpus Christi 158.25 and 851.0125,851.5125 & 852.0125.
You said that you only caught on an automated CWID being broadcast on 851.4625 is this freq a typo ?
Also program these 4 freqs as conventional with yes maybe a beep alert with flashing Blue LED setting.
So are these 85x Mhz EDACS TRS freqs that might fill in the site gaps and belong to this fading system ?
I can't think of what these 85x freqs would belong to or were once planned to go to but the following TRS ?
Four County Coastal Bend Interoperational System Trunking System, Corpus Christi, Texas

Did a little research. The 85x are Interop frequencies 8CAL90, 8TAC91 and 8TAC92. I suspect the might get used during a hurricane evac. It makes sense that the 8CAL90 has a CWID as it would be only one on a repeater.

I'll change it back to 464.425. The CC is heard on 454.700 was too faint to lock in and get data. That really makes the bandplan a steaming pile of garbage. Are we certain site 3 is George West?

 

[rattlerbb01]

Added CH 138 (451.875) to Site 7 Cotulla today bringing it up to three frequencies. TG 801 is the most common on this site but I only caught half the transmissions in discovery mode on the 436 because I didn't have 138 mapped in yet. It mostly consisted of what sounded like family members signing each other up for lifetime NRA memberships. Will know more tomorrow.

 

[Michael-SATX]

It's a "Good Friday" to Discover new Talkgroups in Texas!

Paul, TG# 801 RID=810 has the alias of (3C C4) those mineral rights / interest in some oil fields folks
in LaSalle County so heck yeah they are 2nd amendment folks - gotta protect their assets ya hear
Now with your 436 having the new NXDN upgrade you can be all Locked-N-Loaded like yer NRA fellas!

Bob, any more LTR activity other than TG 0-01-023 on 451.3000. I figure that 451.3000 is likely LCN#1
that carried TG 0-01-023. LTR TG format = A-HR-GRP (0=Area-01=Home Repeater-023=Talk Group)
I already submitted the beginings for this Industrial Communications (George West) LTR back on 3/23
so when my submission is up to be worked probably in another week or two we shall go from there.
Did you manually program one of your Pro-197's with all 6 of this LTR freqs as I explained in Post #40 ?
Those steps will help you first nail down what positions these freqs belong before you try to record any
Talkgroups in ProScan. First those pistons (freqs) have to be firing in the right order (LCN#'s) to track.
So when my submission posts the site name will at first read "Unconfirmed LCN's" until your Pro-197
w/ Menu setting of "AutoMove HRs:= On" arranges them BIGLY Read post #40 in this thread again.

 

[rattlerbb01]

Yeah, I got the alias on 801 and they even mentioned the channel name on air a few times. It seems they are using AVL and other neat functions that the system provides their drivers with. Most of the traffic seemed to do with transportation within the Cotulla area. I went ahead and added the talkgroup in a new category for LaSalle County since that is where the traffic is. Their profile says they are spread out around South Texas but radio traffic doesn't support that yet.

Two days of monitoring Cotulla site 7 has only turned up voice traffic on 801, though several other talkgroups have affiliated. Tomorrow and the next day I'll tune it over to site 5 Pearsall and see what we can come up with. It's 34 miles away from here but comes in fair. This is lazy man's scanning now: tapped PSR500 with DSD running and a 436 with NXDN in discovery mode all while I sleep. Wake up, review, post, haha.

I programmed all freqs for the Industrial Communications in GW along with the Centronix system in Corpus as a test. The Centronix system is weak but readable but I have not seen anymore activity out of the Industrial Communication system although the HR did get set to 3 for 451.3. Since that matches up with the Industrial Communication system in San Antonio I suspect that was system being received. I'll keep the system programmed for a while, but I suspect it is dead.

 

[Michael-SATX]

Bob, when you programmed all 6 freqs for the Industrial Communications in George West - Live Oak
Did you initially program the freqs from LCN#14 to LCN#20 ? This help keeps dead freqs out of the way!
The Industrial Communications (North Central) off 18679 NW Military before the Camp Bullis entrance
is pretty far away from you but it does get out good with only 40 watts having a good elevation of 338 ft
Don't throw in the towel yet as our system does NOT have an LCN#1 Home Repeater for TG 0-01-023
That TG may have been transmitted on your 451.3 as an overflow CH because your LCN#1 was busy ?
Of the 6 freqs on the license in GW maybe a few are valid as well as some listed in other cities, etc.
What would be invaluable is if you had a tapped scanner running LTR Analyzer when 451.3 goes active
to reveal your systems true freq map (Like our 451.3 LCN#3 would show LCN's #2,6,10,15,17 as Free).
Also Industrial Communications is famous for "License it Here ~ Use it over There" like listing it behind
the strip center on 2300 NW Military - The "Churchill" Tower that has only cellular no LTR/UHF period !
I don't buy oh it's "In Market" - If I were in charge updating their FCC licenses they would all correlate.
When you have these legacy systems like this in place for almost 20 years there is no excuse to not
edit site frequency groups and get them accurately submitted for the next 10 year FCC License period.

Bob, try this expirement, program up this system below and gauge how you RX the TG on LCN#17 ?
I just set a Home Patrol on Discovery Record mode on this LTR TRS so I will update this TRS sQQn !

ps~ Load it up as an LTR Standard and see how it maps out ? - yep it's the LTR-NET work-around!

Bob, when you programmed all 6 freqs for the Industrial Communications in George West - Live Oak
Did you initially program the freqs from LCN#14 to LCN#20 ? This help keeps dead freqs out of the way!

I loaded the freqs above LCN 18 and they reordered as follows:
LCN 01 - 452.35
LCN 03 - 451.3
LCN 09 - 452.4625

I've seen TG 0-01-023 (5 hits) and 0-01-036 ( 1 hit) but so far signal is too weak to ID.

What would be invaluable is if you had a tapped scanner running LTR Analyzer when 451.3 goes active
to reveal your systems true freq map (Like our 451.3 LCN#3 would show LCN's #2,6,10,15,17 as Free).

I ported SDRPlay into LTR Analyzer but so far have not received anything yet on 451.3.

For the DelMar location I'm seeing channel LCN 07 as the control reporting status of LCN 3, 11 and 15 on LTR analyzer. I have not heard anything on 453.3875.

I can see the other Centronix 09 signal but it is too week to decode.

 

[Michael-SATX]

Good Work Bob,

If one loads 6 freqs in a Pro-197 from in positions #18 thru #23 ... freqs in 21,22,23 will be ignored
and will NOT get AutoMoved period "while scanning" or even "sitting on the wildcard" just as an FYI.
I just did exactly this on one of my Pro-197's with our 6 freq IC-NC-LTR from 18 to 23 as a test for you.
Only my freqs in LCN slots 18,19 & 20 Automoved correctly which is why I said populate them 14 & up.
When I sat on say LCN#23 by MAN/TSYS/Analyz ... ONLY then did get F3 prompt to moveHR to 17 etc.

Moving forward, when my submission posts before the next RRDB update it will lQQk as follows:

001 (1) George West 01 452.350 03 451.3000 09 452.4625 18 451.8375 19 452.2125 20 452.7500

0-01-023 A Company Ops 023 - Company Operations 023 - Business
0-01-036 A Company Ops 036 - Company Operations 036 - Business

You should port your SDRPlay into LTR Analyzer using LCN#01 452.35 since that's the HomeRepeater
that your 2 talkgroups are homed to that freq and will be transmitted on that freq unless it's busy.
Sitting around waiting for LCN#3 451.3 to go active well you maybe waiting for a while for that to happen.
Load up the 6 freqs as above and then see if 18,19 & 20 go active or an automated CWID moves them.
Ultimately, if you get a read from LTR Analyzer that should reveal this systems frequency position map
which maybe it's only a 3 freq system buy there is no harm in taking more time to double check this etc.

As for the Centronix LTR-Net system RX'ing weak for you that should be a trumpet call for Chase or Gus!
You got your own county to deal with .... not that that ever stops me boundries ... what boundries

 

[rbarker]

I'll be in Corpus the first week of June. Anything new? I'm relying on Radio Reference here to try to monitor what I can. I'll only be there 2 nights in the Marina/Shoreline area. What police district is that? I'll try the Wiki.

 

[gus426]

Corpus Christi

Pretty much what's in the database is what I use it will work just use the Shoreline tower Site 2. It's been the same for a while not many changes in the system.

The downtown area is CCPD Patrol 2 Delta 30 beat area. There isn't much activity on the Marina PD talkgroup. I have it programmed but don't ever hear anything of interest if there is anything going on the PD would be dispatched.

Patrol 1 is west CC Annaville/Calallen area Adam District and Sheriff's Dept. Patrol 2 Delta District Central CC including downtown. Patrol 3 Charlie district is Southside mall area east of Ayers st to Airline. Patrol 4 Bravo district is east of Airline all the way to the beach.

I Hope this helps you and I hope you enjoy your stay in Corpus Christi. ONE WORD OF ADVICE DO NOT leave anything of value whatsoever anywhere visible in your car anywhere you go here in this town.

Centronix (LTR Net) Corpus Christi, Nueces Co, Texas

With the Tropo conditions (11pm~5am) I picked up this 75w LTR-NET over 140 miles away in SATX

Centronix (LTR Net) , Location: Corpus Christi, TX Nueces County
LTR-NET Site #1 Del Mar College 03 451.7875c 07 452.125 11 452.3875 15 452.7375 *
LTR-NET Site #2 (2) Centronix 09 452.2375 *

LTR TG # 0-07-080 A Del Mar College - Del Mar College Campus Security - Security (received TG)

LTR Analyzer Results
Site#1=LCN#7=452.1250 (CWID's with Free=3,11,15) and LCN#15=452.7375 (CWID's with Free=3,7,11)
Site#2=LCN#9=452.2375 (CWID's with Free= 3,11,15 ~ this sites freq map is similair to Site#1's map))

When I tuned 452.1250 HR LCN#7 & during CWID it reveals a system freq map of 3,7,11,15 (no #2 etc).
When I tuned 452.7375 HR LCN#15 & during CWID it reveals a system freq map of 3,7,11,15 (no #2 etc).

OK Rob or Case, next time the conditions are right see if you can map freqs from these licensed freqs
451.9125
452.2375 = LCN#9 (Site#2)
452.7250
453.0125
461.8625
463.3875
463.6625
464.7125

btw ~ I saw a few other Site#1 TG's pop up that were not listed such as these: 0-07-159, 0-07-192, 0-07-211

Need info on the Valero Refining (Corpus Christi) system. There is a pending submission about it switching over to DMR Connect Plus but no more detail yet. It is currently in the database as LTR-Net.

https://www.radioreference.com/apps/db/?sid=3602

Please listeners in the area, if you can analyze the system frequencies and see if we can find out any LCNs, site numbers, etc as well as any frequencies/TGs in use.

Thanks all.

They have definitly made some changes I've seen some of the workers with new Motorola radios. I only have access to a TRX-1 with DMR. I'm not sure if I can be much help. I am picking up DMR traffic on some of their listed frequencies for the west plant though. I'm still trying to figure out this scanner especially manually loading systems instead of the web import feature.

 

[gus426]

It's still a trunked system I'm picking up a talk group 43 sounds like refinery stuff (cable up cable down hold what you got) this afternoon. I programmed it in same order as on the website for Valero West Plant only as DMR. I do see the same talk group on differnet frequencies.
