NXDN or Trbo?

[N9JIG]

Is there anyone on the Chicago area that has a VHF NXDN radio that can program it to receive on 161.205? There are extensive digital operations on this channel and we are trying to figure out who it is.

Also, if you have a VHF TRBO radio could you try that?

We presumed it was TRBO at first by comparing it to known operations but now I am not so sure.

While this is often used for railroad police operations I know a few in the business in the area and none know of any digital use of 161.205 here.

Rich, do we have an audio sample. Nxdn and trbo are sightily different in audio formats? I have capability for nxdn format running it threw uhf nxdn. But the questions becomes what format of nxdn 12.5 or 6.25? Most of the licenses come back as 4K00F1E which would be 6.25 the lowest format of nxdn as Im sure your aware of.
