AACo MD Miscellaneous TGs

[K4EET]

In the exploration of my new Uniden BCD536HP scanner, I have activated (turned ON) "ID Search" for the Anne Arundel 800 MHz System (sysid A43F). Of course, that will "find" all active TGs on the AACo System. TGs such as 18160, 18000, 17968, 17936, 6544, 5712, etc. to name some. Some TGs that I am hearing are definitely somebody's police department.

While Radio Reference does not list TGs for non-Public Safety, is there somewhere to identify all of the AACo TGs?

Also, for the miscellaneous TG 17936 that was definitely police (they are running DL and tag numbers as if on 11F - Teletype), is it appropriate to flag this for inclusion in the RR database? TG 17968 is also somebody's police dispatch.

Thanks for your time and assistance in advance. Still trying to learn the in's and out's of RR and scanning in general.

73 (best wishes), Dave K4EET

17936 is Sheriff it is in the Database
17968 is Circuit Court Security which is also in the database found here: Anne Arundel County Trunking System, Annapolis, Maryland - Scanner Frequencies

18160 is Anne Arundel Community College which is also found at the same link above!
6544 is MSP Glen Burnie is also there\
5712 is School Talkgroup also there!

17936 is AACo Sheriff Office Dispatch/Operations Channel
17936 is AACo Sheriff Office Circuit County Security Channel

Both are listed in the database.

On 17936, when there is a priority 1 call in the county being dispatched, they will simulcast (patch) it on the District Channel, Channel 5 (CID), and the Sheriff Dispatch channel.

For your future reference, the database does document all known submitted talkgroups. It is not limited to public safety, and you may note that there are sections on the AACO TRS page and different sections and sub-pages to the county/city pages (for instance, the AACO page) that provide public works and business net information. Hopefully that's helpful in your future efforts to ID stuff!

 

[marksmith]

Confused.
Not sure how you came to the conclusion that all talkgroups are not included in the RR database, or where you were in the database where all these talkgroups were not listed.

The ones you listed have been there for literally years.

Hey everyone, thanks for the info and weblinks! As to Mark Smith's comment, I did not know about the databases mentioned in this thread. I am still on a very steep learning curve. I thought that I had read somewhere that RR did not want submissions that were non-Public Safety but then again I might have been having a bad nightmare. :lol: As I've said many times in these threads of mine, I have a LOT to learn still. So again, thanks for the info and weblinks! I'll check the weblinks out thoroughly after I feed my stomach. It's lunchtime for me... 73, Dave K4EET

Thinking about this, and this may turn out to be a dumb question, if these TGs are in-fact part of the RR database, then why don't they display as alpha tags while scanning? Perhaps the answer is that I just have a small subset of AACo Police and AACo County Fire that does not pick up AACo Sheriff, etc. I'll have to go back to the Maryland/AACo portion and see if there are other groups that I need to add to my FLs. As I keep saying, I'm still on a steep learning curve. :lol: One of these days I'll stop asking dumb questions and actually be able to help other noobs to scanning using RR's resources which is amazing as to what all the database actually includes. Thanks again folks! 73, Dave K4EET

There's (almost) no such thing as a dumb question. Everyone here was a noob at one time ...

There are so many resources out there and questions that have been answered... best to just Google the question. It may or may not have already been answered.

As for the alpha tags - my first guess would be that you may not have the most current library update in your radio (but it may be something else because it seems like most of the TGIDs you mentioned have been in the RRDB for a while now).

If you've only loaded a subset of the known TGs and then go to ID Search, then others will appear as if they aren't known (but it sound like that's the conclusion you may have come to on your own).

If you are going to run in ID Search mode, you'll certainly want to program in the entire system and all TGs first.

Yes, that is what I sort of led myself to think - - I have just a subset of the TGs loaded. I am comparing my FLs' TGs and seeing what I may have missed.

We are getting there... Slowly... :lol:

Howdy again... I'm a little stumped still. I updated the Master HPDB. Then I placed all of the Anne Arundel A43F System in a FL. Then I started scanning for all IDs. As known IDs came up with Alpha Tags, I temporarily "avoided" them.

During the time it took to write this post, I found the following Unknown IDs (according to the scanner). Then I looked at the AACo database (Excel CSV Database) and identified those Alpha Tags shown below:

4880 AA 20C Adm
5040 AA 20H Insp
5392 Ann PW 21C
5488 AA 21F Aging
5680 AA Sch 21L
5776 Ann 21O Tran
6544 MSP P Disp
17936 AASO 13A Ops
17968 AASO 13B Sec
18032 APD 13D Ops
18064 APD 13E TTY
18096 APD 13F Tac
18160 AACC PubSafe
18224 AA DetCtr

Sooooooo... Why are these not showing correctly on the scanner? Is there a way to check what Alpha Tags are in the Master HPDB***?

Sorry for my continued confusion...

73, Dave K4EET

EDIT: *** Without going through all of the different Departments in the HPDB looking for the IDs...

 

[K4EET]

***UPDATE***

Scratch the above and quoted below. I must have been scanning the wrong FL. I checked it again and the IDs are all showing up as known. Geez... I am getting myself sooooooo confused! Sorry for the inconvenience. The database is correct and I was wrong. How embarrassing... :roll:

No problem. Confusion is part of this hobby for sure.

I run AA County continuously on unitrunker and doubt you will note any new talkgroups, though I see in another thread that a couple have shown up just in the past couple days.

It's a pretty stable system that has has very few talkgroup changes for a few years now. Just thought I would pass along that you won't see much unidentified coming up on search.

If you are looking for systems in the area to run search for new activity, i would recommend the Fort Meade or Naval Academy sites of the Joint National Capitol Region system - frequently has new TG'S showing up, especially recently. Another good one is the First Responders system which has new activity as the system builds and agencies migrate to it.

Enjoy listening.

I just re-read the other thread and I was wrong. The new talkgroups were showing up on the Anne Arundel County First Responders system, not this one. So even more unchanging than I indicated above.

Thanks for the info, Mark. I'll check out the other systems that you mentioned. What I am basically doing is exercising all of the possibilities of the Uniden BCD536HP scanner. Its a lot of fun and things sure have changed since 1978 when I had my first and only other scanner; a Uniden Bearcat 800XLT.

I helped set up AACo's new 800 MHz system before I was medically retired in 2005. I can see quite a few changes from the system that I knew. I was working for the Police side and responsible for all of the HT and mobile radios. Back then it was the Motorola XTS5000 and Astro Spectras. Ironically, I was working for Motorola as a Systems Engineer when AACo's first 800 MHz system went in with STXs and Syntors.

You might enjoy the occasional times when the techs get working on the AACO system. They have a couple of talkgroups listed.

They are not on often, but when they get on there, you will hear them for hours, tuning each frequency or channel in the system from different tower sites, etc.

The other two systems I mentioned, as well as the Maryland Aviation Administration system at BWI are all better systems to exersize your 436 in search. They all have talkgroups that are not listed in the database. The MAA site mainly after a snowstorm.

Enjoy the radio.

They are making some enhancements to the Joint National Capitol Region system such that by listening locally to Ft Meade or the Naval Academy sites, you will hear bases all around the region now. I am seeing a lot of new talkgroups that are not yet in RR for the JNCR system, I guess mainly due to whatever changes are being made.

I'll have to take a listen to see if I can identify any of the new talkgroup users. 73, Dave K4EET

Seeing unit id 27303, which I have historically logged as a communication tech radio, keying up over and over on talkgroup 6864 on the AA system, which I show as an unassigned talkgroup.
Unitrunker logging 50+ key ups today. No voice or audio.

After years of monitoring every talkgroup id on the AACO system (since well before PD went digital), this afternoon for the first time ever I heard activity on 5424, which is labeled as the "health department" in RR.

The designators were EM3, EM4, and similar. It sounded like they were at the Naval Academy, but I am guessing just because they kept mentioning leaving by "gate 6". Something was probably going on at the academy as I also heard Navy police protecting an area for helicopter departure around 2:30, and discussions on 5424 were a lot about when food would be over, etc.

Have no idea if I was listening to the health department after 2 hours of listening.
