New Wiki Page - Unknown Spotsylvania County P25 Talkgroups

[N4VKF]

I know in the past when I've monitored systems with Harris consoles, sometimes the dispatcher is in the clear (due to operator error) for a few days and then goes back to encrypted after a bit. Not saying that's the case here by any means. It happens pretty often with Charles City County.

Question to confirm this is not the case - are the dispatchers transmitting with the same ID all the time, or are they using different IDs every so often? Not sure what kind of schedule Spotsy's ECC runs, but I'd look for different IDs around shift change times, so maybe 0600/1800 or 0700/1900. Also anytime you hear a new voice. When a dispatcher needs a break, usually another dispatcher pulls the channel up on their console, so the ID will change for a moment.

If all of the different console IDs are in the clear, that means it's intentionally clear. If it's just one console that's clear, it's probably a matter of time before they go back. I'm hopeful, though! It might start a trend.

I've caught the same ID through multiple days. If I remember correctly a particular seating location is designated for Patrol 1.

Yeah. I suspect that the Harris symphony consoles (or whoever is programming them) makes the talkgroup default to encrypted, but it remains selectable by the dispatcher. Then, when they load a new configuration, the talkgroup goes back to secure. I know the Motorola MCC7500s can be "strapped" secure without providing the dispatcher the ability to toggle, but also have an option to make encryption selectable.

I was within range of Spotsy's system tonight, and observed the console RID of 41100510 in the clear on "Patrol 1", I observed within that same timeframe similar RIDs from what I can safely assume are also consoles of 41100530 and 41100550, encrypted. So my assumption remains the above that a dispatcher accidentally changed their console to be clear on Patrol 1, and at some point soon, or as soon as someone from their agency sees this thread, the console will be changed back to E.

*The RIDs may not be exactly correct, they're from memory, but the point stands.

So your observations of the RID specific selectable encryption is correct. I was up that way today for a family event and and the 4110510 was in the clear, 30 minutes later it switched to 4110530 and was encrypted, then the 4110510 RID popped up and it was clear. Units were still encrypted, so it’s definitely a user end error

Shhh

Heard a transmission today on 7106. The speaker made reference to this being a future "SpED Transportation" channel. I am guessing that a future realignment of the School Transportation TGs is coming.

Well the encryption off on Patrol 1 was fun while it lasted. I think they corrected the console settings. :

Sad. It's a treat when it happens though.

Caught 6042 today with some sort of training. It may be in use by the regional training center. Similar traffic occurred on Command 4.

 

[N4VKF]

I believe today was the 2024 North Anna Vopex exercise or a 2024 Hurricane evacuation exercise. These may have been separate events.

Spotsylvania County was using the following talk groups:

Public Safety 1
Public Safety 2
7103 - Schools - (Evacuation Drill)

With 7104 previously being identified as a Schools Emergency talkgroup. I guess 7103 is Schools Emergency 1 and 7104 is
Schools Emergency 2

Catching TG 6058 today. All radio traffic is encrypted.

 

[N4VKF]

TG 7513 has some traffic today. Appears to be IT testing routers or internet connections. This maybe a new IT technician talkgroup.

 

[N4VKF]

TG 7522 is a catch this morning. The traffic sounded like a radio check with the SO dispatch.

 

[N4VKF]

Caught TG 7140 today. It may be Brock Road Elem. I am also catching TG 7105 tonight but the traffic is encrypted. This maybe another school emergency management frequency active due to the Tropical Storm.

7140 is Brock Road Elem.

7503 (encrypted) active 11/5/24. This is probably a Schools talkgroup.

I think 7105 might be the new home of the Transportation office to schools for the regular buses. I think they encrypted 7105 and 7106 now.

7515 is another School Bus Talkgroup

I think i figured out what this talkgroup is. Drivers today made reference to talkaround or a Tac A. I think this is "Bus TAC A"
