Does anyone know what data services Oswego City/County may be using over the CNYICC P25 network?

There's a continuous stream of UDP/IP data packets using port 231 that the network is sending out to the radios. They're also using Motorola's Automatic Registration Services (ARS), so this may be some type of data network overlay service.

Denny, I have seen the stream on Madison County too. So I am not sure it is actually Oswego County. Could be something AMR is doing?

I have some inside contacts I will see what I can find out but it might be some time.

Would that be the AVL or GPS service ...?

Possibly, but they're using Motorola's ARS service, like what is used with MotoTRBO DMR, so I would have anticipated seeing LRRP style GPS messages.

I ran the decoder a bit more and the messages are going to a variety of mobiles: Oswego City (850xxx), Oswego County (860xxx), NYSP Troop D (894xxx), a Madison county radio (700702).

The message format appears to be some form of fixed-length status messaging.

When they Did the Radio System Change from 800 to CNYICC they added AVL Units that ran through the radio in to County Owned Vehicles and other agencies

Had 3 Pis with 3 SDRs running OP25. Moved to 1 desktop and thought I should switch to multi_rx.py, but I am losing significant amounts of audio now.
