All over NW and North Central Ohio I have heard CW IDs on AAR 91, but more rarey I see on my NX210 ≪RECEIVE DATA≫ in 12.5 kHz NXDN. I have tried setting my RID to 1 to see if I could receive any data but I couldn't. NS is licensed for MO at 50 watts and FXO at 27 under multiple licenses for this frequency. Anyone have any idea what that channel is used for?
Norfolk Southern NXDN data on AAR 91
- Thread starter dryfb
- Start date
Might be for the grade crossing monitoring system. IIRC they're using 161.565 in Central Ohio for it.
That would make sense, I figured it was either that or EOTs.
I have been a Rail Fan since 1980s, of course I didn't get a scanner until I maybe 14 or 15 years old. Putting in my hands is
Have any sdr dongles and DSDPlus?
No, I haven't even put much consideration into getting an SDR.
Would be interesting to see what data is being transmitted.

Tom, do you know how that system works ???
Does it only send out a signal when a train is going across the crossing ???
Maybe one day some software authors could develop software to interpret the nxdn data stream being used in rail devices.
I really don't know. From what I've heard it sends diagnostic info out if there's a problem.

OK, thanks for the information.
