If you check the emission designator on the FCC license application, here is what I came up with: 8K30F7W = 12.5 kHz voice and data NXDN (IDAS, NEXEDGE). Sadly, there isn't a scanner currently manufactured that can decode this format. I was hoping they would go Project 25, but so much for interoperability.
