• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

All discussions related to the State of Tennessee's TROOPNET, especially UNID talkgroups, and tower sites should use this thread. The TVRTS will be a subsystem of this expanding Project 25 TRS, and should be discussed here as well.

The Tennessee Dept. of Safety has petitioned the FCC to being testing of their new TROOPNET sites in the Nashville area. Sadly, these new sites will Project 25 Phase II TDMA capable. More details are available on the FCC Web site:

Even though these sites are Phase II TDMA "capable" does that mean that is what they will use, or could they use Phase I. Is there any way of finding out?

How are you getting the information on the P25 phase II? I dont see any info for that on the application.
I sure hope that THP will NOT be using Phase II TDMA, as there are no scanners that will receive this. However, I was concerned before the administrator started this thread,as I noticed in the RadioReference database for the Tennessee Valley Regional Telecommunications System, which I think TROOPNET will be a part of, that two of the talk groups, #3 and #16231, under the Radio Technicians, at the bottom, show a "T" under the mode column which means "TDMA Capable".

I am going to try and program this system into my GRE 500, using the frequencies shown on the license, to find out if I can receive any traffic. Should I program it as P25 Auto?

Under the emission designators area of each frequency:

Action Performed Add Emission Designator 9K80D7W Action Performed Add Emission Designator 8K10F7W
http://wiki.radioreference.com/index.php?title=Emission_Designator&diff=84114&oldid=84113

This tells you what type of modulation will be used. From what I gather, this system will support Project 25 Phase 1 and Phase 2 modulation.

Here is an existing license modification for TEMA 800 MHz sites. They are modifying the emission designator to: 9K80D7W. This is "P25 Phase II fixed-end 2-slot TDMA."

Thus far I have not heard anything on the Troopnet frequencies I programed into my Uniden 396XT or GRE-500. However, I still receive TEMA traffic on the TVTRS system on both radios, and THP on low-band. So, it appears they have not yet switched over. I hope that GRE and/or Uniden will come out with a new scanner SOON that will receive Phase II TDMA!

So I guess we're supposed to put our Unid's for the TVRTS here huh? Well here it goes, anyone have any idea which prison uses space capsul names for different wings? Unid TGID 15105 is active and mentions Gemeni and Apollo gates and areas. I am wondering which prison this would be. It's not listed in the database. Thanks.

Yes. Since the TVRTS is being absorbed into Troopnet, it will make things much easier to identify talkgroups, since they will roam freely from each zone. It will be interesting to see if the future Memphis/Shelby County P-25 simulcast system will be a part of this system or not.

The state of Tennessee, has applied for their first VHF-High band Troopnet trunking site. Located in Dover County, near the town of Stewart, this should be the first of many more VHF Phase II TDMA sites to come. More information is available on the FCC Web site:

I can't quite understand why we're discussing an unmoitorable system here? It seems to me all this is depressing news. The scanner hobby is being snuffed out, at least when it comes to public safety, so I for one wouldn't want to be talking about such depressing news. I mean as far as I know I doñt think any scanner maker out there is even attempting to make a unit that would crack MotoTRBO or this Phase II TDMA garbage. Then you have NEEDLESS encryption, geesh. Such sad times. P25 and digital technology is the worst thing that's happened for the scanner hobbyist.

Easy now, the sky isn't falling, take a deep breath. TDMA IS monitorable with software, GRE also just released some beta firmware that supposedly does track true Phase II P25. Just because there's a chance of using encryption on this system doesn't mean everything is going to be locked down. As far as I know, I can count on both hands what systems are P25 and completely encrypted across the country.

Clearly there's enough to discuss here if we're already ~17 posts into this discussion. If all you have to contribute to the discussion is gloom and doom, then that's what it'll become. Let's keep it positive and minimize speculation until we actually see where this system is going, it's still early in it's infancy.

Does this mean that the GRE-800 can now be upgraded to receive TDMA Phase II?
