I had ORNGE in my monitoring set up yetserday. I did not capture any LMRN TG activity on the local sites. I was at the airport when ORNGE arrived and departed. I also did not see any activity on any DVRS. The helicopter landed and the crew went to the local hospital . All I saw was activity on the regular EMS TG. Using DSD decoding the aliases was able to confirm that it was the ambulance at the airport talking as they transported the crew to and from the hospital.
The Ornge land ambulances seem to use 22103 and have logged 7 different ambulances and a couple different console ids

My research into the Delta and Echo EMS designations has come up blank too. I remember hearing on FleetNet emergency button activations and the portables Delta and Echo clearing. All the EMS people I know have no idea why they use Delta and Echo my guess is that the original reason has been lost to history.
D= driver
E= escort/attendant
P= para/trainer

kybervon: good work thats how I would be reading the alias. did you get the RID associated with it?

Bruce: OMG that is kind of obvious when you think about it. Thank you

Everyone. MTO is active with the snow. We know that aside from a few MOT RIDs that identify the MTO yards most MTO aliases just come up with a repeat of the RID. FYI OPP mobiles do the same. We can start fleshing out the vehicle assignments by listening to MTO and getting the unit name or description from the operators talking on air

RID OTA Alias Description
215789 MTO-M-215789 Snowplow 214

When the radio checks are done we should be able to get the supervisor RIDs.

I believe that the CACC talks to ORNGE aircraft on PCOM, and dispatches the land ambulance to meet the aircraft on the local EMS TG.
I think ORNGE also relies on cell phones when on the ground. Certainly our local EMS all have cell phones as well.

Here is another hospital alias that I am not aware of
radio id 752175 AH-HAM-NGH

I also have and ambulance alias but not sure of the county
radio id 752489 "2010 HP" It was on the Hamilton Simcoe 2 talk group
Might be a mistake and should be HD and not HP

Nice catch,

I saw "2094 HP D" the other night on 20822 (Halton North). I guess they were doing an interfacility transfer and had their portable on at the hospital.

The ambulance may have been a unit transporting to that hospital. I have ssn similar cases where a ambulance from one county is active well away from home.

The hospital may be Niagara General Hospital (Greater Niagara General).

Tracking down the EMS stations and Hopsital RIDs/TG is the current project. At least with the hospitals we can match a RID to the Hospital ER TG (23xxx). The RID alias tells us the dispatch area and clue to the hospital name. We can also work on the hospital l
ist assuming only hospitals with a ER will have radios on LMRN.

Your right Mike. Good work on IDing the initials. Also looking in my list I see

752184 AH-NIA-GNG

Sometimes the best way to identify a hospital is to see which units visit it by logging the patch. Then identifying which EMS station that unit works out of. Finally mapping the units station and seeing which hospitals are near by that have similar initials.

1005 also looks like it's another BMR channel
P25, BEE00.AD9, 1005, 100127, 50, Normal, 0, 2024/12/11 13:55, "", "BMR-OPS-100127", 56E8D4A1

I also see a K9 unit for MNR.
P25, BEE00.AD9, 5354, 402449, 50, Normal, 2, 2024/11/27 11:50, "", "R8107 K9 C582", 32EB2720
and hmm..
P25, BEE00.AD9, 5354, 402803, 50, Normal, 3, 2024/12/13 13:11, "", "R1120 - Unmark", C38D954C

Out of curiosity I am working on identifying the last 8 characters of captures "C38D954C" . I suspect this is a internal lCRC of some type used by DSD to verify the data and is NOT part of the OTA alias or anything else.

Could be or maybe some internal checksum of some type.

I was wondering if it might include some date info/CRC, as I have noticed references of DSD resubmitting ID's because they were stale.

I do not want to hijack the thread with a side topic on how DSD may be functioning internally. I believe we all are super grateful for the DSD authors having successfully added the OTA decoding. I am now looking more closely at the data being seen on the "data" frequencies assigned to each site.

If anyone want to discuss this possible CRC and what it is you can DM me and we can put out heads together on identifying it. As a note we are NOT trying to decompile DSD we are simply satisfying the curiosity itch on what this 8 character string is.

Back on the RID/Alias list. It should be possible to combine many .radio files in to one master RID/Alias text or XML file. I believe that DSD does not let you combine the .radio files together but we can make a reference file that may help some add custom aliases to unknown RIDs they may have seen.
