state troopers are still on analog. i drove thrue mobile last week heard A136 talking to dispatch. A is troop location, and 136 is trooper number.
That may be, but they are also digital in certain areas. They are definitely using Mobile county P25 system.
analog is still used state wide but some digital is used also.Is that just a simulcast, or separate from the old analog repeaters? I used to listen to the Mobile post since it was one of the few analog VHF signals left around here, but I rarely heard any activity, and most of that seemed to be one-way dispatches to troopers well outside my listening range.
RadioJonD:Might be time to load 154.6875, 154.7025, 154.9425, & 155.4675 as NXDN for trooper traffic.
If there is any use at all, I would suspect only mobile to mobile simplex for now.

RadioJonD:
For the four frequencies you suggest programming as NXDN, do you happen to know the appropriate RAN code?

No, sir. No insider information this time.
The KA2108 mobile license was updated to authorize NXDN on only those four. Of course, that doesn't mean usage but curiously only those four out of 28 (30, if the two lowbands are counted) were changed to add NXDN.
I check that license at least every three months. In fact, mobile licenses, in general, often offer insight.
I checked the KA2108 license, but I only see 8K10F1E, P25 C4FM voice added. 12.5 kHz NXDN voice is 8K30F1E.
P25 would make more sense as many/most of their mobile radios should be P25 capable by now.
Warren, do you know the frequencies for the ABI? I've always assumed they operated on the ALEA (State Trooper) frequencies which may or not be true. I would also appreciate the P25/NAC codes if you have them.That's interesting you said P25. Back in 2008, Prattville got hit with a EF-3 tornado. I was listening to the different agencies that were assisting in the aftermath, including the Red Cross. I managed to pick up a then-ABI agent. He was transmitting on the old ABI frequency in P25 mode. I even got his NAC. He realized his radio was on the wrong channel, since I next heard him in analog on another frequency (I can't remember which one.)
In some parts of the state you will also hear them mention "the link" quite often. This refers to their Critical Linc handsets. For those who may be familiar, Critical Linc is the LTE replacement for the Southern Linc iDEN system. Critical Linc provides them push-to-talk communications with bases and other troopers statewide, and is unmonitorable.
