Galveston county sheriff units question

[kmartin]

I have been monitoring the Galveston county sheriff T.Gs dispatch channel 1 and the alternate channel 2
both dispatch sheriffs department and police units through out Galveston county as well as constables
but not sure the difference of what areas of the county channel 1 covers and what areas of the county
channel 2 covers i have used the record feature to try to figure this out but i just makes it more confusing
is there anyone currently monitoring these channels that can help or maybe post the info on the county"s
wiki page ?
Thanks

Try listening to where you hear the Beach Patrol. Also listen for keywords such as "Broadway", "Seawall" or "Seawall Boulevard".
That would most definitely be Galveston Island. Then the other channel would "probably" be the mainland Galveston County - Texas City, LaMarque, Hitchcock, Santa Fe, Dickinson, Bacliff and San Leon. Just a guess, but it's a good start.

I was curious if anyone knows the unit numbering system for GCSO. I figure that the ....P... units are patrol, ....J...are the paddy wagons, ....B...are beach patrol, but I can't figure out what the 3 digit number units are and other units (are ...C... constables?) I currently live overseas but I used to live in Galveston County before I moved and I listen on Broadcastify to keep up with what's going on back home.

Also, there's a feed on BC that says Hitchcock Fire which is 154.37, which is actually the fire departments for North Galveston County (except for League City). Lately though, I haven't heard GCSO dispatching any calls on there for Bacliff or San Leon (my old home) VFD's, so I'm wondering if they went to another freq. I hear Dickinson and Santa Fe all the time, but recently haven't heard Bacliff or San Leon VFD, or Galveston EMS in that area being dispatched by GCSO.

I was thinking "P" was for constables because of PCT districts. But i could be wrong i know that high island, tiki island and bayou Vista dispatch on GSO 1. But not sure what other areas are on this channel. As far as GSO 2 i have no clue but they do dispatch units on GSO 2 as well.

 

[TXDispatcher1]

Well, I'm pretty sure P units are patrol units because I hear them making patrol calls in Bacliff and San Leon all the time. I also hear some units with 3 digit numbers making calls in those areas too, but I can't figure out what they are. Do you have any idea if Bacliff and San Leon VFD's and Galveston EMS in that area have moved to a frequency other than 154.37? I haven't heard them talk in quite a while.

 

[TXDispatcher1]

Also, I'm sure that 9900 units are Hitchcock PD

 

[kmartin]

Bacliff and San leon as well as Galveston are on the TXWARN system. I haven't heard a thing on the old Vhf hi frequencies in a long time
You are probably correct on the patrol unit's and Hitchcock has it's own PD talkgroup and as far as i know not dispatched by GSO

 

[TXDispatcher1]

I heard Bacliff and San Leon VFD's on 154.37 as recently as a month ago. When was the last time you heard them? I still hear Dickinson and Santa Fe VFD's on there. It sounds to me like Hitchcock PD is dispatched by GCSO. They don't seem to have their own dispatcher. I'm starting to think that the ...C... units are constables because I heard them today getting out at various addresses to serve papers and you don't hear them that much at night. They occasionally do some patrol work but not that much. I still don't know what the three digit numbered units are that I hear on GCSO. The 1900 and 2000 units on Galveston PD are definitely patrol units. Sometimes I hear 1700 units but I don't know what they are

 

[TXDispatcher1]

I finally figured out that ....C... units on GCSO are definitely constables ( I believe that the 1st number is the precinct). Also, ....B.... units are definitely beach patrol. Three digit numbers seem to be off-duty officers and officers working extra jobs.

 

[TXDispatcher1]

Also, the GCSO dispatcher identifies itself as "Galveston", and the Galveston PD dispatcher identifies itself as "Headquarters', so that helps you to know who you're listening to.

1700 to 1720 unit's are Jamaica beach PD and are dispatched by Galveston PD on tg 3263

I'm trying to figure out the unit numbers for Tiki island PD I'm pretty sure The are dispatched by GCSO on channel 1. I recently posted unit numbers I've verified on This county's wiki page

They are 18xx units

I remember when Galveston began identifying itself as Galveston. The city and another coastal city in the Northeast USA were on the same frequency. I don't know if they were CSQ or had the same PL tones or were low band. But, they had similar street names and wharf identifiers, and it caused a lot of confusion late at night. So, they decided to identify themselves as Galveston and the other city's name. Similar identifiers in the local greater Houston area started identifying themselves thusly, too. I don't recall who Katy PD mirrored on their VHF frequency in, if I recall correctly, in Brazoria County, but I can tell if it is probably a veteran in Katy if they ID as Katy when talking with the dispatcher.

But Similar events happened when conditions were "right" between Harris County SO channel 1 and Angelina County Sheriff. I recall hearing Angelina County relaying HC Channel 1, patrol District 3, unit's calls to the HC dispatcher and Angelina County repeating the HC Dispatcher's traffic to the units late at night. I think they had the same PL tone. VHF was fun to listen to late at night, back then.

Ok, thanks for the responses about unit #"s from you and SB819. Does anyone know what type of units that xxDxx are on Galveston SO? I don't hear them very often but I can't figure out what they are. Also, does anyone know what type of units the 3 digit numbers on Galveston SO are? Some of them are definitely off duty officers, but others seem to be something else-for example, 3 digit unit numbers that begin with 4 that patrol in Bacliff and some other areas.

 

[kmartin]

They are 18xx units

Thanks for that info senior

 

[kmartin]

After continuous monitoring I have added my findings to the Galveston wiki Page to help understand the area's that GCSO 1 and GCSO 2 patrol hopefully this will help

 

[TXDispatcher1]

I figured out that xxxDxxx units on GCSO are almost certainly traffic units. Also, one thing that 3 digit numbers on GCSO are used for is definitely off-duty officers, as you will hear, for example, a unit say"438 is 10-41 as 2P11". 2P11 would definitely be an on duty GCSO patrol unit. However, I also hear units with 3 digit numbers patrolling Bacliff and other areas, so I haven't figured that out yet, unless Bacliff pays off-duty officers to provide extra patrol in that area as extra jobs. I dunno. Also, I almost never hear DPS units talking to either GCSO or GPD. There seems to be very little coordination between DPS and the local PO-lice in Galveston County. The coordination was much better when the old intercity (155.37/154.95) system was in use.

Bacliff is on GCSO Channel 2 alternate
Unit's are P2x. Or they will include their shift number ..say 1 or 2. So the unit will report as 1P2x first shift or 2P2x second shift and I hope I'm correct on this. I'm going by hour's of recording this T.G
The off duty 400 units I have heard are at the Galveston college here in town. However I have heard unit 403 dispatch to a few calls in the city of Galveston. DPS working in the city of Galveston usually use GPD 2 T.G 3265 when they need assistance from GPD ..or to confirm a warrant however most of the time DPS units are on DPS Texas city channel 1 and I usually only hear the dispatcher and NOT the mobile's unless the repeater has been turned on because of a chase. But haven't heard them much on GCSO channels... however during the topless jeep weekend last year I heard them on GCSO 1 a few times and on the Galveston county events channels. DPS also used drone's during bike rally downtown strand could be heard on events channel as well. Another thing I noticed is DPS talk group's use P25 type II T.Gs where as GCSO uses P25 type I don't know if this really matters

Over the weekend I was trying to listen to the Galveston County Sheriff calls on the Bolivar Peninsula/Crystal Beach and for some reason I was not receiving their calls on my radio, but yet when tuned into Broadcastify, I was hearing lots of activity from the busy Jeep weekend. I tried updating my database and talk groups on my scanner, but still nothing. Apparently they tune to an alternate system for these busy events, but I could not find it this weekend. Anyone know what frequencies or talk groups they use during these busy weekends?
