I can assure you Dare's P25 system is working, the feed I run uses that system. The replies above are all correct
Are you getting full reception bars on your scanner? If not, you aren't picking up the signal. Also make sure your squelch is set correctly since that system seems to be sensitive to that (Mine is set to 4 which is fairly low). Also, unless you have an SDS scanner or a high gain yagi antenna, this system is extremely hard to monitor with a traditional P25 scanner and omni antenna due to all of the severe multipath distortion (it's so bad they had to install a separate multicast site in Buxton).
Also keep in mind they are transitioning to P25 Phase-II sometime in the near future so you will need a scanner capable of that
