Burnet County System

I have a Uniden BCD536HP and have downloaded the ARC536 software and used it to load the Greater Austin/Travis Regional Radio System (GATRRS) and I am only able to listen to dispatch of Burnet/llano counties and not able to hear any mobile units. I have an older scanner that picks up the same transmissions but I guess it is not picking up the digital transmissions.



Any ideas on where to look? I downloaded the database directly from radioreference.com
