[harley092355]

I’ve never heard them talk car to car—must be secret frequencies.
I’m in Tyler area…….

If they are using their Vhf radios to speak car to car, then almost certainly that would be simplex, not via a repeater. If that's the case, then you would need to be very close in order to hear them.

DPS Tyler does have three talkgroups on TxWARN. Do you have those programmed? Occasionally, though rarely, one of the units gets far enough west that their radio affiliates with the Kaufman County site, and I'll catch a little of their communications.

But it's also likely that they are using their MDTs for messaging, instead of voice channels. Other than units assigned to the tollways in this area, I almost never hear any DPS radio traffic other than DPS101 (the DPS helicopter based in Mesquite) who may be working with one of the law enforcement agencies here in the DFW on a suspect search or a pursuit.

They might also be talking on their cellphones, instead of one of the state radios.

every blue moon i'll hear DPS on the ole 154.950 frequency, and it's P25.

Radio is too public. MDC/MDT/In-car computers record everything and the records are retained for years.

Everyone knows to use SMS texts on their personal phones and never on the G-phone. As long as a personal phone is never used for work duties, it is darn near subpoena-proof and employers have no access to what is said or texted.

Do you have the four base channels programmed in with a NAC of 162? That's the main car to car I hear them on around here, and not very often. They generally use one of the channels that is not active where they are.

This is what I heard them on in Uvalde a few days ago, Mobile C. That’s actually the first time I heard them unit-unit simplex in many years too.

There is supposed to be at least 3 car-to-car simplex channels
155.4450 162 NAC Mobile 1
155.4600 162 NAC Mobile 2
159.2175 162 NAC Mobile 3

I used to hear Mobile 1 in the Wichita Falls area a lot but they may have changed it recently.

Back in the day.........I played softball with a couple of troopers. One of them gave me the local car to car and needless to say some of those conversations were quite spicy.
This was in the mid-80s so things have changed quite a bit since then.
The DPS narcotics channel I stumbled across one night was interesting too.
All long gone.

I have heard 154.95 used a couple of times out west of Ft Worth...and surprisingly it was only a couple of months ago. DPS101 was headed west where a trooper had pulled over a pickup and the fellow ran. They used 154.950 to talk to the units on the ground!!! Didn't take 'em long to find the guy and DPS101 was headed back to the east.
The TG on the Parker county system is heavily used by the units out this way.....both simplex and the Mineral Wells dispatch office.

Back in the day 154.950 analog was a powerful intercity channel that the sheriff dept used car-2-car as well as communicating with DPS. the old DPS mustangs, crown vics and chevy caprices all had what looked like a 5/8 wave whip on the back and those radios put out 100 watts. I miss the analog days. don't get me started about patching and agencies not being able to talk to each other post haste these days lol.

Need to be super close as most of the units have all lost their antennas to drive thru car washes. At least in my area they have.

I have 154.950 programmed for PL 156.7 and again with NAC 293.
I don't believe I've ever heard anyone use this since the old Intercity Mobile "channel 3" days.
Maybe I should leave it open in case someone is using something other than these.
Has anyone heard it used other than these?

Texas Statewide Interoperability Channel Plan.
154.950 CTCSS 156.7 mobile to mobile calling channel.

 

[riverradio68]

I have heard various NAC codes on 155.7525 V CALL 10 some of which have been DPS chit chat. I listen to a butt load of DPS and have never heard them on TX CALL 1 or 2. Generally, they use (Like Tom mentioned) Mobile 1, 2, 3.

Back in the Dark Ages (analog) 154.95 was the mobile transmit half of the intercity pair. The base transmit frequency was 155.370. Intercity took up two "channels" in car our radios. One was labeled Car to Car, 154.95 Simplex CSQ. The other was labeled either Mobile to Base, or just Intercity, 154.950 transmit/155.370 receive CSQ. Dispatch also has two intercity channels. One was 155.370 Simplex CSQ to be used to talk to other agencies base to base. The other was 155.370 transmit/154.950 receive CSQ for dispatch to be able to talk to mobile units from other agencies.

During an event, such as a multi-agency pursuit, our dispatch would either relay information to us on our channel or direct units involved to switch to intercity.

Just about every DPS car that I've seen recently have had VHF antennas. So, I suspect there may be car-car comms, especially in rural areas that don't have a TRS, or it may be used for the GATRRS vhf systems.

the good ole days when austin police would link or patch radios, they would call it doubling. sometimes if they were short staffed they would have 1 dispatcher working 2 sectors, usually when someone called in (cough-cough) sick, you'd hear: "WRL498 WSB863 david and frank are doubled"

so to tie dps in in this, whenever there was a robbery or officer needs assistance or other hot call, a dispatcher would patch all radio channels and do a city-wide broadcast, including the CID, narcotics and other back channels, and if the dispatcher was good, they would also select DPS base and APERN which would go out citywide to not only apd, but sheriff, dps, and other agencies. man i miss the good ole analog days.... crystals, the latest police call from radio shack, etc.

 

[Giddyuptd]

Being they have vhf and 700 capabilities anyone ever sniff around the 700 licenses for conventional use?

 

[kmartin]

I used to hear them on 155.4450 when I lived in Mineola back in 2013
that was used for DPS car to car for Tyler and Canton
