If you listen to the broadcastify playback it sounds like testing TGs as there is occasionally someone reading off numbers. Weird they are using the 92xxx UIDs as I've logged those as LRAA UIDs

I'd surmise that those would be more for airport operations, such as snowplows, maintenance, etc. The airport public safety officers are "dual hatted" and handle both law enforcement and firefighting missions and as such are heard on 1601 mostly. They also still have a VHF alerting frequency from the comm center to the fire station. That alerts public safety to fire and medical incidents.

I added the UofL traffic channel to the node it’s the only TG for UofL in the clear. I’m very curious what’s it use is. I labeled it in the DB as cardinal cab but I think it’s used by UofL PD for student escorts. Is anyone had previous experience monitoring this TG?

I just saw someone on Broadcastify put a feed for EMS I haven’t heard any traffic yet. According to the description the person is streaming encrypted talkgroups no idea if it’s just random garbled mess or if it has a key or not the feed link is below this post

I plugged this in a scanner and will give it a listen. I got a suspicion of what this talkgroup may be, but want to listen to confirm.

The database does not indicate this is an encrypted talkgroup. It is shown as "MED ALERT". It could very well be the talkgroup used by MetroSafe to contact ambulances to say "Hey XXXX, you got a call".

If that is indeed the case, it probably would not be an encrypted channel.

The feed was updated to reflect the MED ALERT channel. It was originally setup on all 3 MED Dispatch channels which are clearly encrypted.

Seems like the provider doesn't know how to read the database.

I’ve monitored MED ALERT in the past and all it usually that happens is the occasional accidental keyup and units accidentally keying the channel before switching to one of the 3 dispatch channels

I found out/had my memory refreshed. This is kind of an alerting channel for suburban fire ambulances. When they return to the fire station, they switch their portables to this talkgroup. Then, when needed for a call, the dispatcher will do a "Call Alert" for their radio. That's where the radio id is punched up on the console and call alert is pressed. When their radio "beeps" they go to the appropriate med channel and say "I'm here, go ahead with the dispatch".

There shouldn't be any tones, voice, etc. as a matter of routine on this talkgroup. The med crews just needed a quiet place to park their radios.

TGID 77 is not in the Database pretty Active but Encrypted, assuming this is another LMPD TAC?

These TG’s are TAC channels that are used for internal operations of the department such as training detectives and SWAT. these channels can be used at any time if a commanding officer request them for a special event per LMPD‘s operating procedures

8,9,10,11 are all encrypted, I'm thinking they might be Patrol Tacs as they are close to the Patrol Channels, but you are correct we don't know, I'm using Unitrunker to track RID's and you can see a pattern
70,71,72,73,74,75,76,77 are also on the pattern not all had voice grants some were just affiliations

According to LMPD’s SOP under the channel assignments it says as follows

“Under routine operations, departmental units will be assigned to the following radio operations channels:
• Police 1 – Divisions 6 and 7
• Police 2 – Divisions 3 and 8
• Police 3 – Divisions 1 and 2
• Police 4 – Divisions 4 and 5
• Traffic CIS – Traffic Unit, Major Crimes Division, and Vehicle Impoundment Unit
In addition to the assigned channels, there are two (2) service channels, Service 1 and Service 2, which, like the operations channels, are monitored by a dispatcher 24/7.
Car-to-car (C2C) communications may be conducted on one (1) of four (4) channels identified as PD C2C 1 through 4. Unless advised otherwise, patrol division members should use the C2C channel that corresponds to their operations channel (e.g. Divisions 6 and 7 should normally use PD C2C1 for car-to-car communications).
Four (4) tactical (TAC) channels, PD TAC1 through 4, are available for conducting special operations, if requested by a commanding officer. The commanding officer must contact MetroSafe if he/she wants the TAC channel monitored by a dispatcher.”
