Tomorrow, March 14, 2010, Anne Arundel County will have a full scale disaster drill involving Light Rail. State agencies will also be involved. There are gonna be 400+ participating in the exercise. 6AM-2PM.
Looks like they're up / setting up on Anne Arundel Fire talkgroups INDIA (272) and HOTEL (240) and possibly one or two of the disaster talkgroups (6416 / 6512). Police talkgroup 11- HOTEL (17520) may be patched in as well.
There may also be some activity on a encrypted policed talkgroup (32368) but that activity may be unrelated to the exercise.
22-A (6416) looks to be the exercise dispatch talkgroup - the exercise dispatch was just announced (0908).
22-B (6448) looks like the response (tac) channel / talkgroup.
6512 seems to be the exercise police talkgroup.
