Welcome to RR unkadon,
The RR DB: Arkansas County Arkansas page lists the frequencies for Stuttgart PD as "(TRBO capable)", which indicates that their system can use DMR/MOTOTRBO technology.
The RR Wiki indicates that

The RR Wiki indicates that
"There are no scanners on the market that can copy DMR MOTOTRBO systems. Apart from using an actual DMR radio, the only other way to receive this system is to use DSD or DSDPlus. DMRDecode can be used to view system information. See the bottom of the DSD article for known working setups. "
So, I'm guessing that the PD is using DMR/MOTOTRBO more often, and this is why you cannot hear them on your scanner.
If you are interested, the RR site has a lot of useful information: You might start with:
- RR Wiki: MOTOTRBO
- RR Wiki: Digital Speech Decoder (software package)
- RR Wiki: DSDPlus
- RR Wiki: DMR
- RR Forums: Voice/Control Channel Decoding Software.
Hope this helps,

Program the frequencies for them manually. Listen and see what your hear. Are you hearing a digital growling noise? If so this would indicate they have indeed switched to DMR. Currently there is only one scanner made that does DMR conventional, and that is made by AOR but it does cost over $1,000.00
Otherwise, the only way to monitor DMR is by running either discriminator audio or audio from a SDR kit to an PC and use software such as DSD+. And hope they are not using encryption.

Almost all of the local PD in SE Arkansas have gone to DMR (Mototrbo). The local radio shops pushed them on these agencies for a while claiming they were secure and unmonitorable by "scanner land." They can be monitored but it takes some work using a PC and software.
Shhhhh!! Don't tell them that they can be monitored!
Actually, I think that some PD agencies already know that they are monitorable, and that in fact they are being monitored. A DMR-using local PD close by to where I live are careful not to discuss sensitive info over the radio. I hear them say "Give me a 21" (i.e., a phone call) a lot.

So, what have you heard? Anything? Does it sound like a diesel engine? if so, that's DMR. If you're not hearing anything then perhaps they've moved to AWIN or another frequency.
With the digital scanners (Uniden and Whistler) you can listen to the AWIN system, which has the state police, highway police (commercial trucks traffic), several other statewide agencies, and a few local agencies scattered throughout the state. So, while it won't pick up the DMR or NXDN radios, you can listen to the AWIN system.
If you want to dig into the computer software to monitor DMR with a SDR dongle, etc., that is also do-able, it just takes some configuring (admittedly I haven't taken the time to dig into it but I know wbswetnam has).
What scanner do you have?
I seem to picking up a lot of differant things. Often from many miles away, much farther than I would have expected. It all seems sum what random tho. Ar county is still using a conventional non digital system I think, as I can still pick them up with my old antique scanners. I'm using a RS pro 197 now. I recently purchased a uniden bcd 996xt, but I haven't figured it out yet. Iv ben farming a few antennas trying to decide what works best.
Well, it is quite possible to hear something on the AWIN system from the opposite side of the state. I don't have time to go into how right now but it has to do with the system and what radios are affiliated with the tower you are listening on.
These links might be of help, if you haven't seen them before:
RS Pro-197: Easier to Read Pro-651/652/106/197 - WS1040/1065 - PSR 500/600 Digital Scanner Manual
Uniden BCD-996XT: Easier to Read BCD996P2/XT Digital Scanner Manual
And no, I am not the Mark who put together those manuals. They are a little easier to follow, however, than the stock manuals...at least in my opinion.
Yes, it looks like both Stuttgart PD and FD are licensed for DMR. If you hear the growling sounds "randomly" that's not a surprise - some DMR systems have frequent data bursts, for reasons I still don't know. The only commercially available scanner which can monitor DMR (assuming that it is unencrypted) is the AOR AR-DV1 which is ludicrously expensive (about $1200).
It's much cheaper to buy a used scanner on eBay or Amazon and modify it with a discriminator tap. The easiest, and safest, ones to modify are the ones which have a pin on the PC board from which you can take the unfiltered audio and send it to a computer for processing. Installing a discriminator tap is actually not as difficult as some folks may think it is, and even if you buy a couple of $100 scanners and ruin the first one in your first attempt at it, it's still a fraction of the price of the AOR AR-DV1.

If the FCC lic has both of the DMR emissions designations, they use both Data and Voice, The Data is used for many purposes, including GPS locating, Text Messaging, Selective Calling/Alerting, and other things. If they are an slower/smaller agency, you won't hear a lot of activity, and thus calls are fewer and further between. If you do hear any digital sounds and never any analog voice, then they are full time DMR, but not very busy.

Stuttgart PD and Fire are using DMR. I have them programmed into a DMR radio and also can monitor them by using a Dongle and the DSD+ software.
So they're unencrypted... Terrific! Please pass on the color codes, slot #s and group call #s to milf.
To the OP (unkadon): another possibility is that you can buy a DMR radio to monitor that system. The TYT 380 is selling for about $140 now on Amazon.com and it comes with the programming cable and software you need (Amazon.com will suggest purchasing the cable along with the radio - don't - it comes with it and you don't need two cables).

Going NXDN or DMR doesn't eliminate "scannerland" but it sure cuts down the size of it. Instead of thousands of scanners out there monitoring local SO or PD traffic, it cuts scannerland down to maybe 10 members of the public listening instead of 2000. They could go with encryption and cut scannerland down to zero but that is added expense and often the signal quality and coverage area are degraded (or so I've read).

Hey, thanks guys. I will check in to the DMR radio from amazon if that will work. Yes its a small community, less than 10k total population. I just figured they were proly so corrupt, they didn't want any body listening in. I hope the DMR radio thing is not as complicated to figure out as these uniden digital scanners are.
