Reynoldsburg City Schools

[wa8pyr]

All,

Trying to update information for Central Ohio. Anybody close to the Reynoldsburg area who could investigate the Reynoldsburg City Schools radio system?

They abandoned the county 800 MHz system a couple of years ago, their UHF license shows DMR.

If you could locate system type and configuration and any other info that would be helpful.

I am working on this now. When I get home I can share what I have.

 

[RakkFO]

I have focused on the Summit campus site since it is closest to me. I am using DSD+ to decode and it decodes as a DMR BS

463.4250 CC12 TS1 - Data
CC12 TS2 - Data
The data is a 4 second burst with 60 seconds off. This goes on at all hours.

463.8125 CC13 TS1 - High School (Summit Campus)
CC13 TS2 - School bus

radio ID's follow the bus numbering

That is all I have for now and don't expect much activity till next year.

OK, thanks. My guess is that the data transmissions are probably AVL data for the buses.

Is there any evidence that the repeaters are networked with any others?

 

[RakkFO]

Interesting thought on the AVL data, any way I can confirm that?

No evidence so far. I am busy this week but will have some time next week to get some more work done on this.

No way to confirm that I know of, unless you have a way to read the data. It's an educated guess on my part; school bus services are getting interested in AVL lately.

 

[RakkFO]

I used DSD once to get some AVL data. I will see if I can try that again. Thanks for the lead

There are only certain types of AVL data that DSDPlus can decode, mainly because there are quite a few proprietary AVL apps that interface with the DMR systems and the author wouldn't have access to the source and it might just not be a possible type that could be supported based upon just figuring out the datastream.

More often than not, at least around here, AVL cannot be decoded on the DMR systems I monitor. Good luck!

Ok I will keep that in mind also. Thanks Mike.

It depends on large part on what information is being sent from the bus. If it's simply GPS position and radio ID being sent (and received by common mapping software), it can probably be decoded. If the school district actually spent beaucoup bucks on a system which has a box on the bus and a box+computer back at the bus barn and merely uses the radio as a transport mechanism for proprietary data packets, you're probably SOL.

Worth a try though, especially considering that many school districts tend to spend lavishly on stuff the taxpayers can see (as well as overinflated administrator salaries), and get really cheap on behind the scenes stuff like radios.
