The database here shows the 153.545 frequency as being FM which would work with your Baofeng. However, their FCC license lists the emission type as DMR (7K60FXE) which cannot be decoded by your Baofeng. In that case, you would need to use a program like DSD+ with your SDR to decode the traffic. If you monitor that frequency with your Baofeng and just hear "data noise," then you can bet they probably switched over to DMR.
