Federal Protective Service - 410.8000
The Federal Protective Service uses 408.2000 [ $201] and 410.8000 [ $201] in the DC area. 408.2000 is usually encrypted, and appears to be the primary dispatch channel. 410.8000 has some encryption, although much of the traffic is in the clear. This frequency was thought to be an alternate to 408.2000, but it appears to be used instead for security for a particular building. There are frequent radio checks, and some units are called "concourse rovers" and "food court rovers." At this point, there hasn't been enough information to identify the location/building.
