The other day I passed by the Transportation Test Center located east of Pueblo. The RR data base shows a number of frequencies in use at the Test Center that have NXDN modulation. My new scanner, a Whistler TRX-2, was able to decode the NXDN traffic so I could understand it. I only heard parts of conversations which made me wonder if their radio system is a trunked VHF system.
Anyone have any information about their system? The RR data base doesn't indicate it is trunked. Any ideas?
