Tonight I heard a DPS trooper tell another trooper to "go to MOBILE 1" . This was the first time I've heard a reference to mobile 1. Any ideas what the frequency this is? Making a wild guess at this but there must be more one or it would be just "MOBILE".

My quick first guess is that it's DPS MOB A as listed in RR. Just a guess.

I have not heard that reference in this area. Wild guess on my part- Possibly going simplex, on either the input (mobile to base or repeater) or the 'base' or repeater output frequency. I seem to recall that years ago, before the transition to P25, I heard an occasional reference to "go direct", which turned out to be both units switching to simplex on the (then) base frequency. A couple times that happened, when I was close enough to catch the simplex exchange. But, again, that is only a guess, could be off-target.

What part of the state are you in? The above is correct if they are not on a TRS, but if they are using a TRS, such as TxWarn P25, Mobile 1 could be a talkgroup.

I'm in Lubbock. I dont believe they when to Lubbock's Trunking system-the talkgroups are referred to as "DPS 1, DPS 2",etc and they are rarely used, but it may be possible. I wasnt able to get to my scanner and do any searching for mobile1. Then again if it wasnt a repeater freq they may be out ofrange.

It used to be called Channel 3 (in most areas). But, I was just suggesting to check that frequency (154.950). It may be called Mobile 1 in Lubbock. But, most likely, it is the Primary in simplex, as was the case before the state administrator decided to put all base stations on the repeater a few years ago.

Live near an Interstate Highway and you might hear it once or twice a week, usually by officers from rural counties passing through the big city trying to decide where to eat lunch.

Mobile 1 is either 155.445 or 155.460 simplex with 162 NAC.
It's not in the database. See Department of Public Safety (DPS) (TX) - The RadioReference Wiki.
Also see the programming software screen shots at about 1:20 in this video https://www.youtube.com/watch?v=CkG4xuVirWo. This conflicts with what I hear in the Wichita Falls area. They call 155.445 162 NAC "2" or "Mobile".


In Midland the DPS Troopers used 155.445 with NAC 123, but I have not heard any traffic in sometime. They maybe using the laptops for chitchat.

Midland is near I-20 and other agencies are always in Midland for training. I still can not remember the last time I heard any traffic on 154.94 or 155.37.

Been so long ago that I've heard anything on 154.95 or 155.37.
Same here. Nowdays if the troopers want to talk to the local SO they use the SO channel.

Was that car-to-car simplex or a repeater?
155.445/154.695 NAC 123 is BASE C. The database shows Midland is BASE B.
Maybe they changed and the database is wrong now.

, but I have not heard any traffic in sometime. They maybe using the laptops for chitchat.
If you don't hear anything at all on any of the DPS channels then maybe they are using one of the local trunked systems.

The database could be a joke by now. The smart thing is to ignore the database and program all the DPS frequencies with NAC search if you have a NAC capable scanner.

The Midland DPS Troopers have the VHF/800 radios where they can talk on the PBRPC Regional System, but never have heard them on the system. Never heard them on the Midland old EDACS system or the new Midland P25 Phase II system. I think they are using the laptops. I am using my GRE PSR-500 to search the area for VHF.

There's also possibility of cell phone use along with the MDTs. For an example, check out Animal Planet's "Lone Star Law." The game wardens use cell phones to talk with each other and their dispatcher, as well as the local sheriff departments. They also use radios as necessary, such as with their own units, sheriff departments and DPS (probably on Law 1).

When DPS was analog they had a car to car channel. 159.2100 PL: 162.2 It was used as simplex. When they moved to Digital no one ever updated the DB to reflect that data. I run that in scan but have never heard any traffic on it which was simplex based. I'd have to favor TXCALL2D or maybe (long shot) DPS CLE. More than likely they were referring to the TRS and you missed the chat. Go ask a game warden if you really want to know, those radios are programed almost the same (Z2, Z1 is TPWD) and the GW won't laugh at you!

Probably because they changed it when they went digital. It MIGHT be 159.2175 162 NAC Mobile 3 now.

The talkaround channels in the wiki article have not been verified, did not come from a known reliable source, and the channel names conflict with what has actually been monitored and what is shown in the TPWD radio programming video.

In the analog system Ch 9 was 159.21 simplex PL 162.2 and Ch 10 was supposedly 159.21/154.665 PL 162.2 repeater, but I never heard it used. It may have been for temporary portable repeaters. Channels 10-18 were the same repeater pair with different tones used thoughout the state.

Here is something interesting ND5Y. Long time ago when Midland Police Dept. had their G.E. 4 channel mobile VHF radios. The PD had 154.665 in their channel 4 so they could talk directly with the DPS. That was interesting.

Looking at my current log, I saw 155.46 with NAC 162.
